Problems solved by technology

In the process of making bitumen or modified bitumen waterproofing membrane and the construction of applying the waterproofing membrane, toxic gas with strong odor will be volatilized, which will cause great impact and harm to production, construction personnel and ambient air.
Moreover, in the application of exposed parts of the roof, long-term exposure to the sun's ultraviolet rays can easily accelerate aging and cause cracking. The black color of the asphalt can also easily absorb the heat of the sun and heat up, making the asphalt or modified asphalt layer soften, sticky and bulging
As a result, leakage is caused, which seriously shortens the service life of the product

Abstract

The invention relates to a waterproof roll with multilayer structure, comprising a plastic substrate, asphalt or modified asphalt layers and a color nano fluorine-silicon-acrylate layer and a faying surface plastic side membrane; wherein, the first layer of the asphalt or modified asphalt layers and the color nano fluorine-silicon-acrylate layer are coated in sequence on the upper surface of the plastic substrate, and the faying surface plastic side membrane is compounded on the upper surface of the asphalt layer or the modified asphalt layer on the two sides of the color nano fluorine-silicon-acrylate layer; wherein, the thickness of the asphalt layer or the modified asphalt layer is 0.3-6.0mm; the thickness of the color nano fluorine-silicon-acrylate layer is 0.1-1.0mm. The waterproof roll with multilayer structure of the invention has colors on the surface, can prevent the erosion of strong solar ultraviolet and other harmful gases in the air, suppress the volatilization of the toxic gas in the asphalt under high temperature, improve the environment and be wholesome to the society. The waterproof roll can improve the service life of the asphalt or modified asphalt waterproof rolls, and can be taken as an environmental protection product with double functions of waterproofing and decorating and beautifying the environment.

Description

technical field [0001] The invention relates to a building waterproof material, in particular to a waterproof coiled material with colored nano-fluorosilicone-acrylic compound layers for roofing or other exposed surfaces. Background technique [0002] At present, the asphalt or modified bitumen waterproofing membrane produced by modifying asphalt or SBS, APP and other materials is a common waterproof material widely used in buildings in China, and belongs to the middle and lower grades of waterproofing membrane products. The product is popular in the construction industry because of its low price. This kind of asphalt or modified asphalt waterproofing membrane is used in a large and wide range. It is mainly used for foundation waterproofing of buildings with deep buried bottom layers, and some are also used for roofs and other exposed buildings. parts. However, it is necessary to compound a layer of aluminized polyester film on the surface of the exposed part or make a laye...
