The waterproof coiled material comprises two main categories of polymer modified asphalt coiled materials and synthetic polymer coiled materials, and the waterproof coating is also divided into polymer modified asphalt coating, asphalt-based coating, synthetic polymer coating and the like. Although the waterproof investment only accounts for 1 percent of the total construction cost of the buildingHowever, 99% of complaints of the quality problems of the buildings belong to house leakage, 65% of buildings have the phenomena of water leakage and water seepage according to official data, and the market of the waterproof material is huge according to the data, and the market of the waterproof material in China reaches billions of production values according to official statistics. The annual growth rate is more than 20%. The building waterproofing industry would also benefit from the increased need for infrastructure waterproofing brought about by sponge city construction. Underground pipe network construction is expected to bring 4,000 plus 5,000 billion investment, and new increment is brought to the demand of waterproof materials. In addition, the industry would benefit from the waterproofing requirements associated with the renovation of an inventory house. The stock of houses is over 500 hundred million m280% of the buildings are built 5 years ago, and the house renovation plugging is increased explosively; the demand of the house renovation in 2014 on the waterproof material only accounts for 5.8 percent of the total demand, the waterproof demand of the house renovation in 2015 is increased by 1.3 and 0.2 percent in anticipation of increasing the construction area in 2015 and 2016, and the waterproof demand of the house renovation in ten years is expected to be increased by more than 15 percent.
However, most of the building waterproof materials in China contain organic materials, and have serious fatal defects in the aspects of weather resistance, water resistance and the like, particularly contain carcinogenic substances such as formaldehyde, toluene and the like. There is currently no more solution to these problems. In recent years, although some breakthroughs are made, the difference from foreign countries is still large.
At present, the waterproof material has the main problems of complex construction, different thicknesses, easy cracking, pollution to construction environment, short service life and difficult storage.
