Environmentally Friendly Waterproof Material 2011 Becomes Market Focus

The southern part of China, especially Guangdong Province and Hainan Province, is affected by the tropical and subtropical climate. It is in a state of high temperature and heavy rain throughout the year. In the north, it is mostly frozen and cold and the main wind is sand.

This requires that manufacturers of waterproof materials and contractors for waterproofing projects should not simply use the same type of waterproof material and the same construction method in all areas for promotion and application. In the United States, TPO environmental protection waterproof materials, EPDM environmental protection waterproof materials and planting roofing systems known for energy conservation have greatly surpassed the trend of traditional waterproofing membranes.

The TPO environmental protection waterproof material manufactured by Carlyle of the United States, the waterproof system formed by the combination of EPDM waterproofing material and Carlisle auxiliary materials can completely meet the US UL "A" class fire protection standard (the highest grade). Beijing Carlyle Waterproofing Material Co., Ltd. is the only authorized company of Carlyle in the United States. The company fully introduces the advanced equipment and technology from Carlyle of the United States and adopts the most mature formula in the United States to produce CCW-525 one-component polyurethane waterproof. Coatings, their physical and chemical properties fully meet the requirements of the United States ASTMC836, ranking the leading domestic level.

CCW-525 one-component polyurethane waterproof coating construction method is based on the United States Carlyle advanced and mature waterproof system, based on China's actual and related national standards compiled.

It is understood that the United States Carlisle company has white EPDM and white, tawny TPO waterproofing membrane, making the material's solar reflectance is much higher than the traditional waterproof material, thereby effectively reducing the indoor temperature, significantly reducing air conditioning and refrigeration cost of. According to calculations, this product has reached the energy-saving star requirements and LEED (Note: LEEDLeadershipinEnergyandEnvironmentDesign issued by the United States Green Building Council) sun reflex index requirements.

TPO waterproofing membranes also perform very well in reducing waste on site and reducing volatile gases. Carlyle's CCW-525 one-component polyurethane waterproof coating has been used for many years in the history of production and application. It not only has excellent technical performance, but also is an environmentally-friendly waterproof material. The construction method has been applied in the underground, toilets, swimming pools, subways, tunnels and other projects of dozens of national key construction projects in China, and has achieved very good waterproof effect. Practice has confirmed that CCW-525 one-component polyurethane coating system can ensure the overall waterproofness of the waterproof layer and excellent waterproof effect under any non-exposed conditions.

At present, environmentally-friendly waterproof materials have been successfully used in Olympic venues, new locations of CCTV, Guangzhou Opera House, Beijing Zhongnanhai Huairen Hall, Tianjin Airbus A320 China assembly line plant, domestic major cities subway, Beijing Pangu Daguan and many other national priorities. engineering. And export to many countries to be recognized.

Polyurethane waterproofing materials for home improvement New favorites For home improvement waterproof materials, the current market is diversified, domestic, imported, joint venture; high-end, mid-range, low-grade. Home-installed waterproof material is commonly used in petroleum asphalt polyurethane waterproof coating, environmental protection polyurethane waterproof coating and polymer cement waterproof coating.

Polyurethane waterproof coating has been widely used in waterproof engineering because of its excellent physical and chemical properties. Of these, tar-based polyurethanes are the most widely used.

However, with the development of society and the improvement of people's living standards, people began to pay more attention to environmental protection and their own health of home improvement waterproof materials. Coal tar contains a large number of aliphatic and aromatic compounds, and has a strong irritating odor. Among them, cesium, naphthalene and other components are extremely harmful to the human body.

The pollution of tar-type polyurethane to the environment has drawn increasing attention. In 1997, the Beijing Municipal Construction Commission proposed that manufacturers wish to develop environment-friendly polyurethane waterproof coatings suitable for home-improvement waterproof materials; at the end of 1998, it issued the “Restriction and elimination of tar-type polyurethane waterproof coatings.

The Beijing Municipal Construction Committee also encourages the development and recommendation of six types of environmentally friendly polyurethane waterproof coatings; (1) one-component polyurethane waterproof coatings; (2) colored polyurethane waterproof coatings; (3) inorganic filler-type polyurethane waterproof coatings; (4) water curing Polyurethane waterproof coating; (5) Petroleum pitch-based polyurethane waterproof coating; 6) Petroleum resin type polyurethane waterproof coating. The former four are not used in the market because of their high cost. The latter two have become the direction of development of various companies and have been applied in the market. Home improvement waterproof materials now advocate the promotion of non-tar type polyurethane waterproof coatings, mainly based on environmental protection requirements, tar-type and non-tar type polyurethane waterproof coatings. Mainly in: 1. Smell tar type: There are severe irritating odors, coating film has odor; Non-tar type: only slight odor or odorless, coating no obvious smell. 2. Film burning method tar type: It has a pungent odor, produces a dense black smoke with black floc formation, and burns rapidly; Non-tar type: There is a loose or slight odor, a small amount of black smoke, slow burning , leaving the fire is not flammable. 3. Mixed tar type: The viscosity increases at the initial stage of mixing, that is, the thickening phenomenon when mixing; Non-tar type: The viscosity does not change during compounding, and there is no thickening phenomenon.

The above three methods can basically determine qualitatively the tar-type and non-tar-type polyurethane waterproof coatings, which can prevent the tar-type polyurethane coatings from counterfeiting the non-tar type, so that excellent home-installed waterproof materials can enter the market. The polymer cement waterproof coating (JS coating) is a two-component water-based architectural waterproof coating made of a polymer emulsion such as acrylic ester and cement as the main raw material and added with other admixtures. It has the characteristics of “hardness and softness” and has both polymer coating properties. The extensibility and water repellency of the film also have the advantages of high strength of the hydraulic binder and ease of adhesion of the moisture base layer.

Home-made waterproof material coatings use water as a dispersant to solve the environmental pollution caused by the use of solvent-based waterproof coatings such as tar and asphalt, as well as harm to the human body, so consumers can purchase products they want without worry.

After 2010, the main type of low-carbon, energy-saving and environment-friendly waterproof material dominated the Copenhagen conference. Low-carbon is a theme of this year's development and an inevitable direction for future development. Therefore, if you want to open a door and window in the market, you must take environmental protection. The route can be established in the market.

In recent years, China's modern waterproofing business has grown from scratch, from small to large, especially since the reform and opening up has been rapid development. At present, China's waterproof material has formed including SBS, APP modified bitumen waterproofing membrane, polymer waterproofing membrane, construction waterproofing Coatings, rigid impervious and plugging materials, including a complete series of high-middle and low-end varieties and functions, and formed an industrial system consisting of materials, production, equipment manufacturing, waterproof design, professional construction, research and teaching, and business network. However, compared with advanced countries, we still have many problems in terms of product quality, application technology, market cultivation, etc. In particular, the proportion of high-quality products is relatively small, and the overall level is not high. All of these require us to work hard in the new century.

During the 10th Five-Year Plan period, China’s economy will enter a new stage of development. The average annual growth rate will remain at 7%, and the GDP will increase from 9.5 trillion in 2000 to 123 trillion in 2005. The scale of investment in fixed assets will increase from 3.5 trillion yuan in 2000 to 4.7 trillion yuan in 2005. The implementation of infrastructure, housing, urban construction, municipal construction, and the strategy for the development of the western region will provide greater access for the waterproof material industry. Market. Only 5.7 billion square meters of residential buildings (2.7 billion square meters of town) were completed, and industrial buildings and other various types of housing were 3.4 billion square meters. By 2010, the number of city-based cities will increase from 667 in 2000 to 800, and investment in urban housing construction will double than in 2000. Referring to the above indicators, the demand for new types of waterproof materials will increase significantly in 2005 and 2010, and linoleum will gradually decrease (this forecast is appropriately adjusted on the basis of the National Chemical Building Materials “10th Five-Year Plan” and the 2010 Development Plan Outline). The sealing material will need 120,000 tons in 2005 and 160,000 tons in 2010.

In the next 10 years, SBS and APP modified bitumen waterproofing membranes will continue to be the leading products and will be developed in accordance with the requirements of the National Building Materials Bureau's "Catalogue of New Building Materials and Products Guidance" and market trends; Polymer waterproof membranes will focus on the development of EPDM and PVC. (P type) two kinds of products, and actively develop TPO products; waterproof coating prospects are promising polyurethane (especially one-component) and acrylic; sealing material is still focused on the development of silicone, polyurethane, poly*, acrylic four major categories; waterproof Insulation materials, rigid waterproof materials, anti-seepage and plugging materials, metal roofing materials, asphalt shingles, and geotechnical materials will have a certain market. Other materials will follow the market, but we must adhere to the principle of helping the superior and eliminating the inferior and improving the overall level of waterproofing. We must resolutely resist and severely crack down on fake and shoddy products. In the next ten years, we will also vigorously improve material support and construction technology.

In the next decade, the market will have a bright future and the situation facing it will be severe. The majority of members of the Building Waterproofing Material Association will be the backbone of the industry. There will be “tigers” in front of them (foreign products will enter China); there will be “wolf” behind (counterfeit) Fake and shoddy products will continue to hit the market. We hope that a group of leading enterprises will learn the hero Wu Song of Jing Yang Gang and fight tigers, and must not "dance" with wolves.

Looking into the future, with the steady and rapid development of the national construction industry and the continuous improvement of people's lives, we will require more quality waterproof materials and construct a large number of waterproof engineering products. We believe that through hard work, by 2010, China's new waterproof material will dominate, product structure will become more reasonable, product quality and application technology will also be close to the world's advanced level and field.
