Waterproof material is an important functional material required by the construction industry and other related industries, and is an important part of the construction materials industry. With the rapid development of China's national economy, not only industrial buildings and civil buildings require multiple varieties and high quality requirements for defense materials, but also require high quality in industries and fields such as bridges, tunnels, national defense industry, agricultural water conservancy, and transportation. Waterproof seal material.
Since the reform and opening up, China's building waterproof material has achieved rapid development. Waterproof material has got rid of the backward situation under the dominance of paper tar mats. At present, it has five categories including asphalt linoleum (including modified asphalt linoleum), synthetic polymer waterproofing membrane, building waterproof coating, sealing material, plugging and rigid waterproof material. product. In 1995, the output of new waterproofing membranes was 42 million square meters, accounting for about 5% of the output of waterproof membranes. China's waterproof material has basically formed a waterproof material industrial system with complete categories, product specifications and grades, and technological equipment development that has begun to take shape. There are some foreign varieties that we basically have.
At present, compared with foreign advanced countries, China's waterproof materials have the following major problems: First, the product structure is irrational. At present, the production and use of new waterproof sealing materials are very small, and the paper felt still accounts for 95% of the waterproofing materials; The product quality is generally low, and the fake and Chang products flood the market. Third, the design and application technology needs to be improved. The leakage of the building is still quite serious. The waterproof material industry needs to adjust its structure and regulate the market.
