Abstract
The invention provides a polymer waterproof material, which comprises polymer colloid. The polymer colloid is obtained by mixing the following ingredients (by weight): 20-48 parts of hot melt adhesive, 1.7-5 parts of naphthenic oil, 10-20 parts of white cement, 30-60 parts of quartz sand and 0.3-1 part of green pigment. The polymer waterproof material also comprises a fetal membrane and an isolating membrane. The polymer colloid is uniformly dip-coated between the fetal membrane and the isolating membrane. The polymer waterproof material has excellent weatherability, peel strength and waterproofness, and can provide a skin-type waterproof barrier for building materials. Environmentally-friendly non-asphaltic base raw materials are adopted, and the ingredients are not complex. The preparation technology is simple, and production cost is low. The polymer waterproof material has economical and environmental-protection characteristics and has a wide prospect for large-scale industrial application.
Description
technical field [0001] The invention belongs to the field of waterproof materials, in particular, it relates to a polymer waterproof material. Background technique [0002] At present, my country's waterproof materials are still dominated by asphalt-based waterproof materials, accounting for 65% of all waterproof materials, polymer waterproof membranes account for about 15%, and other waterproof materials account for about 20%. Among them, polymer waterproof membrane is a typical new building waterproof material. Because of its excellent performance, in line with the purpose of building material innovation, and the rise of light steel structure buildings, it has developed very rapidly in recent years. [0003] In the prior art, on the one hand, the traditional asphalt-based waterproof materials have low peel strength and insufficient waterproof performance. With the prolongation of use time, their waterproof performance weakens; on the other hand, the use of asphalt-based ma...
