A kind of preparation method of waterproof roll material resistant to plant root system penetration

Abstract

The invention discloses a preparation method of a waterproof coiled material resistant to penetration of plant roots, and relates to the field of building waterproofing, comprising the following steps: S1, selecting glass fiber cloth as a glass fiber layer, and coating asphalt on both sides of the glass fiber layer Paint, put waterproof film on the asphalt paint, the asphalt paint will bond the waterproof film and the glass fiber layer together, the asphalt paint will form an asphalt layer after drying and curing; S2, a modified asphalt paint is coated on the outside of a waterproof film, and then A barrier layer is placed on the modified asphalt coating, the modified asphalt coating connects the barrier layer and the waterproof membrane, and the modified asphalt coating is cured into a modified asphalt layer after drying to obtain a coil; S3, the coil prepared by S2 The material is calendered to obtain a waterproof membrane.

Description

technical field [0001] The invention relates to the field of building waterproofing, and more particularly, to a method for preparing a waterproofing membrane resistant to penetration of plant roots. Background technique [0002] In recent years, with the continuous expansion of urban construction, people's living standards continue to improve, but the green space in the living environment is getting smaller and smaller; for this reason, people rationally use the roof area to expand the green space of the living environment, mainly including in the Planting small shrubs, sagebrush, sage and other green plants on the roof can effectively purify the air, improve and beautify the environment. [0003] Building a roof garden first needs to solve the problem of waterproofing. At present, asphalt waterproofing membranes are used more. It is called bitumen waterproofing membrane; it is mainly used for building walls, roofs, tunnels, highways, landfills, etc., and is a flexible bui...

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
