Waterproof materials on the market thereare two categories: First, polyurethane waterproof coating. Such materials aregenerally made from polyurethane and coal tar as raw materials. It is volatilein the tar gas toxicity, and is not easy to remove, so in 2000 was banned inChina. Still in the sale of polyurethane waterproof coating, is the use ofasphalt instead of coal tar as raw materials. However, the use of suchcoatings, the general use containing toluene, xylene and other organic solventsto dilute, and thus contains toxicity; the other for the polymer cement-basedwaterproof coating. It consists of a variety of water-based polymer synthesisof emulsion and mixed with various additives, high-quality cement composition,polymer (resin) flexibility and cement rigidly integrated, making itimpermeability and stability of the outstanding performance. It has theadvantage of convenient construction, integrated low cost, short constructionperiod, and non-toxic environmental protection. Therefore, the polymercement-based waterproof coating market has become the protagonist.
