Abstract

The invention relates to an environment-friendly type elastomer modified asphalt waterproof roll which is a multi-layer composite structure. A long fiber polyester base material reinforcing layer is arranged in the middle of an environment-friendly type elastomer modified asphalt layer; and the environment-friendly type elastomer modified asphalt layer consists of the following components in parts by mass: 45-55 parts of low-smoke asphalt, 4-12 parts of SBS (styrene butadiene styrene) thermoplastic rubber, 1-4 parts of powdered butadiene styrene rubber, 5-10 parts of natural asphalt master patch, 0-3 parts of polybutylene elastomer, 5-10 parts of rubber processing oil, 0-2 parts of polyolefin auxiliaries, 0-2 parts of amide wax, and 20-30 parts of 180-mesh talcum powder. The environment-friendly type elastomer modified asphalt waterproof roll has the beneficial effects that: by optimizing and applying environment-friendly raw materials such as the low-smoke asphalt and the like, a low-temperature production process of the modified asphalt is realized, so that generation and discharge of atmospheric contaminant such as non-methane hydrocarbon, particulate matters and the like in a production process of the elastomer modified asphalt waterproof roll are effectively reduced, and therefore, the pollution problem in the production process of the elastomer modified asphalt waterproof roll is completely solved.

Description

technical field [0001] The invention relates to a preparation method of a waterproof coiled material, in particular to an environment-friendly elastic body modified asphalt waterproof coiled material. Background technique [0002] After more than 20 years of development in China, the traditional modified bitumen waterproofing membrane is constructed by hot-melt method because of its excellent high and low temperature resistance. The method is simple and reliable, and it can be constructed all year round. Small impact. Therefore, it has been actively promoted and applied in China, and it has occupied more than 70% of the national waterproof material market. It is expected that the market share of modified bitumen waterproof membrane will remain high in the next 5-10 years. However, at present, there are many domestic manufacturers of such products, most of which are small in scale and backward in management and technology. They add a large amount of waste asphalt, waste rubb...
