Glass fiber construction waterproof material is a new type of building waterproof material that was developed in the United States in the 1960s, gradually promoted in the 1970s, and developed rapidly in foreign countries in the 1980s.
Fiberglass waterproofing materials are divided into two categories: glass fiber cloth and glass fiber mats. After the substrate is impregnated with the modified asphalt, a mineral powder or a covering material such as a polyethylene film is sprinkled on the surface of the asphalt, which is used as a new building waterproof material.
The material has high tensile strength, good anti-leakage performance, and can meet Class A waterproof standards. It is an ideal material for solving the problem of building roof leakage. Because the material of this material is inorganic fiber, it has good anti-corrosion and anti-aging properties, and it is not degraded under wind, rain and light conditions on the roof. In the application of subway, underground and pipeline engineering, it has excellent waterproof and antiseptic properties. Service life up to 20 years. After the material is compounded with modified asphalt, its elasticity, softness and thermal shock resistance are greatly improved, such as modified by APP (atactic polypropylene), with better elasticity and dimensional stability, suitable for high temperatures and the sun It is used in areas with strong radiation, and modified with SBS (styrene-butadiene-styrene) maintains good flexibility at low temperatures of -15-25 degrees Celsius, and is more adaptable to cold regions and structural deformations in the north. Building waterproofing.
According to reports, in the early 1980s, the rapid development of waterproof materials for glass fiber construction in the United States almost completely replaced paper-based asphalt waterproof materials, thereby increasing the production of glass fiber in the United States by nearly 200,000 tons. Finland is one of the most developed countries in the world paper industry, but according to the Finnish Ahistrom company, the country has also eliminated paper-based bituminous waterproofing materials. The company owns 3 glass fiber construction waterproofing material production lines with an annual production capacity of more than 200 million square meters. Meter.
It is said that at present, the waterproof material for glass fiber construction in European countries has accounted for 45%-50% of the total building waterproof material, while in the United States it is as high as 80%, while China still only accounts for 8%-10%. This shows that the market potential of China's glass fiber construction waterproof material is great.
At present, China's glass fiber construction waterproof material market demand is about 20,000 tons. According to the forecast of experts, by 2010, the total market demand will quadruple, breaking the one-million-ton mark.
In addition, glass fiber can also be used as auxiliary reinforcement materials, civil engineering reinforcement materials, and heat insulation materials. The material form is mainly a small grid organization and has a considerable amount of use in the stadium construction. Others mainly include the reinforcement and crack prevention of high-grade asphalt concrete pavements on soft roadbeds, and the reinforcement and reinforcement of reinforced concrete structures of buildings and bridges. In addition, there are sound-absorbing materials, decorative materials, coatings and composite materials. Glass fiber cotton felt and cotton board can be used as thermal insulation materials to join building envelopes. Experiments have shown that the addition of 50 mm thick thermal insulation materials to the building wall in Beijing can achieve an energy saving efficiency of 60%.
