Problems solved by technology

[0008] The purpose of the present invention is to aim at the above-mentioned defects existing in the prior art, and to provide an environmentally friendly modified bitumen waterproof coiled material with a heat-sealing strip, on the one hand, the shrinkage stress at the edge of the coiled material is effectively weakened, and the aging of the overlapping parts of the coiled material is avoided The resulting edge shrinkage and warping stress caused the problem of disengagement and separation, and at the same time effectively solved the problem that the "blind bonding area" between the upper and lower coils and the base layer in the overlapping part of the length direction of the coil cannot be improved by hot melting. On the other hand, it solves the pollution problem in the production process of the existing modified asphalt waterproofing membrane, so that the air pollutants such as carbon monoxide, sulfur dioxide and hydrogen sulfide produced in the production process of the modified asphalt waterproofing membrane Emissions drop by more than 50%

Abstract

The invention relates to an environment-friendly modified bituminous waterproof sheet material with heat sealing strips. According to a technical scheme in the invention, the bituminous waterproof sheet material asphalt comprises a base reinforcement layer, an environment-friendly modified asphalt layer, an upper isolation protection layer, a lower isolation protection layer, heat sealing strips,thickness gradually-changing areas, construction overlap joint warning lines and the like. The environment-friendly modified bituminous waterproof sheet material has the beneficial effects that: the production efficiency of modified asphalt is improved, the emission amount of atmospheric pollutants such as carbon monoxide, sulfur dioxide and hydrogen sulfide in the production process of the modified asphalt is reduced by 50% or above, and pungent smells in the preparation process of the modified asphalt and the production process of the bituminous waterproof sheet material are greatly reduced;through ingenious structural design, the problem of disengagement and separation of overlap joint parts of the sheet material is avoided, so the hidden danger of water channeling in a bonding dead area of the sheet material is effectively avoided; system viscosity of the modified asphalt is effectively reduced, and the flatness and smoothness of the surface of the sheet material are effectively improved; and production efficiency is greatly improved, production cost is remarkably reduced, and the lodging resistance of the sheet material in a high-temperature environment is improved.

Description

technical field [0001] The invention relates to a modified asphalt waterproof coiled material, in particular to an environment-friendly modified asphalt waterproof coiled material with a heat-sealing strip. 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. It has occupied more than 70% of the national waterproof membrane market and more than 50% of the national waterproof material market. The rate remains high. 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 rubber powder, waste plastics, and ...
