Preparation method of plant root system penetration-resistant waterproof coiled material

Abstract

The invention discloses a preparation method of a plant root system penetration-resistant waterproof coiled material, and relates to the field of building waterproofness. The preparation method comprises the following steps of: S1, selecting glass fiber cloth as a glass fiber layer, coating two sides of the glass fiber layer with an asphalt coating, placing a waterproof film on the asphalt coating, and bonding the waterproof film and the glass fiber layer together by the asphalt coating, drying and curing the asphalt coating to form an asphalt layer; S2, coating the outer part of a waterprooffilm with a modified asphalt coating, then placing a barrier layer on the modified asphalt coating, connecting the barrier layer and the waterproof film together by the modified asphalt coating, drying and curing the modified asphalt coating to form a modified asphalt layer, thus obtaining a coiled material; and S3, carrying out calendering molding on the coiled material prepared in the S2 to prepare the waterproof coiled material.

Description

technical field [0001] The invention relates to the field of building waterproofing, in particular to a preparation method of a waterproof coiled material resistant to penetration of plant roots. Background technique [0002] In recent years, with the continuous expansion of urban construction and the continuous improvement of people's living standards, the green area in the living environment has become smaller and smaller; for this reason, people rationally use the roof area to expand the green area of ​​the living environment, mainly including Green plants such as small shrubs, sage, and sage are planted on the roof, which can effectively purify the air, improve and beautify the environment. [0003] To build a roof garden, the first thing to do is to solve the problem of waterproofing. At present, asphalt waterproofing membranes are used more often. Asphalt waterproofing membranes refer to the waterproof material products made by impregnating bitumen waterproof materials...

AI Technical Summary

Problems solved by technology

[0004] However, the existing asphalt water membrane generally does not have the function of anti-plant root puncture, and because this type of waterproof membrane has a single formula, the strength of the membrane is low, the crack resistance and anti-aging performance are not high, and it can be easily punctured by plant roots. Penetration, causing building damage and leakage, and even affecting the structure of the building
