Waterproof coiled material with high tensile strength

Abstract

The invention discloses a waterproof coiled material with high tensile strength. The material comprises a blank body, a self-adhesive material base layer, an anti-sticking isolation film and a covering layer. A blank base is arranged on the blank body. The blank base is prepared with a filament polyester non-woven fabric material. The self-adhesive material base layer is coated on the blank body. One side of the self-adhesive material base layer of the blank body is provided with the anti-sticking isolation film; the covering layer is arranged on the other side of the self-adhesive material base layer of the blank body. According to the invention, the covering layer is added on the basis of existing waterproof coiled materials, such that the tensile strength of the waterproof material can be effectively improved. The added covering layer can protect the waterproof coiled material, and assists in improving the waterproofing performance of the coiled material. Therefore, the waterproof coiled material has the advantages of long service life, wide application range, and multiple applications.

Description

technical field [0001] The invention relates to the technical field of building waterproofing, in particular to a waterproof coiled material with high tensile strength. Background technique [0002] Waterproof membrane is a waterproof material product made by impregnating asphalt or polymer waterproof material on the carcass in the form of membrane. According to the different main components, it can be divided into asphalt waterproof membrane, polymer modified asphalt waterproof membrane and synthetic polymer waterproof membrane. It is mainly used in building walls, roofs, tunnels, roads, landfills, etc., as a building material product that resists external rainwater and groundwater leakage. It is used as a non-leakage connection between engineering foundations and buildings. The first barrier of waterproofing for the entire project plays a vital role in the entire project. [0003] Waterproof membranes age under long-term sunlight, air, rain and other natural environments...

AI Technical Summary

Problems solved by technology

[0003] The waterproof membrane will age under long-term sunlight, air, rain and other natural environments, and the waterproof coverage will break and become unstable

With the increase of the use time of the waterproof membrane, the surface of the waterproof material is worn, and the ductility, tensile strength, and durability of the waterproof material decrease accordingly, which makes the service life of the waterproof membrane short and the waterproof effect is poor, resulting in damage to the surface of the building. Local water leakage and water seepage often occur
