Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that the flow of air causes the seeds of the plants to fall to the upper surface layer to take root. Since the roots of the plants are well developed and have strong penetrating power, it is easy to penetrate the waterproof membrane, so that the waterproof membrane loses its moisture. protection of buildings

Abstract

The invention discloses a modified bitumen waterproof coiled material and a preparation method thereof. The film layer contains the following components by weight: 200-230 parts of PVC resin, 7-8 parts of light stabilizer, 10-12 parts of heat stabilizer, 65-80 parts of plant root inhibitor; the modified asphalt waterproof roll of the present invention The material has the advantages of being able to inhibit the growth of plant roots, reduce the possibility of being penetrated by plant roots, and have a longer service life.

Description

technical field [0001] The present invention relates to the technical field of waterproof rolls, and more particularly, to a modified bitumen waterproof roll and a preparation method thereof. Background technique [0002] Waterproof membrane refers to a waterproof material product made by impregnating asphalt or polymer waterproof material on the carcass, which is provided in the form of a membrane, which is called a waterproof membrane. The waterproof membrane is mainly used for building walls, roofs, tunnels, highways, landfills, etc. It is a flexible building material product that can be rolled into a roll to resist external rainwater and groundwater leakage. There is no leakage connection between the building and the building, which is the first barrier of the entire project waterproofing and plays a vital role in the entire project. [0003] The invention patent application with the application publication number CN108248128A discloses a modified bitumen waterproofing ...
