China Paint Online News Information: The air quality
has become a concern of the whole country. The amount of energy consumed by a building is directly related to the degree of haze produced. According to statistics from the Ministry of Housing and Urban-Rural Development, the bricks used in rural buildings are not only a waste of resources, but also destroy farmland. The total energy consumption of domestic construction, operation and building materials production accounts for 49.5% of the total energy consumption of the whole society, while the energy consumption of heating is even more alarming, and the energy consumption of heating in the northern region is 6 times that of Europe. The cement production process required for traditional buildings is a major carbon emitter. The development of new energy-saving building materials can effectively and rapidly reduce energy consumption. Only by vigorously researching and developing new technologies and materials related to building energy conservation can related enterprises achieve the goal of energy conservation and emission reduction.building materials innovation, so that the industrialization of housing is possible. Residential industrialization is a kind of residential construction mode of change, that is, from semi-manual, semi-mechanical relatively backward construction mode, into an industrial production mode. Japanese consumers have been building houses using the residential industrialization model for nearly half a century, and Europe and the United States have long abandoned the practice of building brick-and-mortar buildings. From our country's point of view, people buy a house in addition to looking at the location, look at the price, also began to pay attention to residential comfort, environmental protection, safety performance, etc. , the previous extensive residential 'production' model will certainly not be able to meet demand in the future.the real core of residential industrialization is to protect the ecological environment and living environment. Compared with the traditional construction methods, industrial construction methods can reduce the use of high-polluting, high-energy and high-carbon building materials such as bricks and cements, the generation of building waste, the discharge of building sewage, interference with building noise, harmful gases and dust emissions, so as to achieve energy saving, water saving, land saving, material saving, the whole process is very environmentally friendly.From the 1970s to the 1980s, due to the high production cost of pure polyurethane waterproof coatings, the main production of two-group tar polyurethane waterproof coatings (851), single-group and pure polyurethane waterproof coating production is very small.the end of the 20th century, the domestic production of polyurethane waterproof coatings is about 30,000 tons, of which tar polyurethane waterproof coatings accounted for 2/3. Production enterprises are mainly distributed in Beijing, Shanghai, Guangdong and Jiangsu and other southeast coastal areas. Among them, beijing area production of about 10,000 tons, followed by Shanghai, Guangdong, each 5000 tons.tar polyurethane waterproof paint pollution of the environment, serious harm to human health and even life safety, in 1999 the state banned the use. The elimination of tar polyurethane waterproof coating, so that polyurethane waterproof coating product quality and environmental performance on a new level, promoting the development and application of China's single-group, two-group polyurethane waterproof coating.Polyurethane waterproof coatings are listed by the Ministry of Construction as the "95th" and "15th" period to focus on the promotion of "ten new technologies" recommended waterproof materials, but also the national chemical building materials "15" and the 2010 development outline of the focus on the promotion and development of waterproof coatings. Therefore, it was estimated and speculated that in 2002, 2005 and 2010, the demand for polyurethane waterproof coatings would be 60,000 tons, 80,000 tons and 100,000 tons, respectively (90% of polymer waterproof coatings).polyurethane products in the domestic waterproof coatings market, is the market share of the second-largest products, occupy the first polymer cement waterproof coatings. At present, the production of polyurethane waterproof coating enterprises have about a hundred, large-scale enterprise annual output of tens of thousands of tons, a total annual output of about 300,000 tons, with a wide range of uses and development prospects.Emined water-cured polyurethane waterproof coating water-cured polyurethane waterproof coating is the Beijing Municipal Construction Commission to encourage the development and recommended use of one of the six environmentally friendly polyurethane waterproof coatings, is a polyether-type, solvent-free environmentally friendly high-grade synthetic polymer waterproof coating, with traditional tar-type, petroleum asphalt polyurethane Compared with water-resistant coatings, with solvent-free volatile, non-toxic, tasteless, construction pollution-free, fast curing and other advantages, in the construction of paint as a curing agent, which is significantly different from other single or two-part polyurethane waterproof coatings, reflecting the new ideas, new technology, with broad market prospects.
