According to relevant plans, the number of affordable housing units to be built nationwide will reach 13 million in the next two years. The large-scale acceleration of the construction of affordable housing will bring considerable market demand to new building materials and construction chemicals such as architectural waterproofing architectural coatings. According to relevant data, during the “Twelfth Five-Year Plan” period, the annual growth rate of China's new waterproof materials will remain above double digits, and the total application volume will reach 1.66 billion square meters. It is understood that at present, China's building waterproof materials mainly include waterproof coatings, glass fiber asphalt tiles, self-adhesive waterproofing membranes and other new waterproof materials, as well as asphalt linoleum waterproofing based on petroleum asphalt paper tire linoleum and asphalt composite tire flexible waterproofing membrane. Coil and the like. Strengthening the research of special waterproof technology and strengthening the new in recent years, many enterprises are expanding their industrial chain and expanding the scale of market operation while expanding and strengthening the waterproof engineering industry. Now they are in the international leading position in the technical application of the building maintenance industry. .
