Polyethylene polypropylene fiber composite waterproof roll

Abstract

The invention discloses a polyethylene polypropylene fiber composite waterproof coiled material, which comprises a sand surface layer, a polyethylene polypropylene fiber material layer, a glass fiber layer, a mineral particle layer, a tire base layer, a POE plastic layer, and a non-woven fabric layer sequentially arranged from top to bottom. Layer, self-adhesive rubber waterproof layer and isolation membrane layer. Adopt a kind of polyethylene polypropylene fiber composite waterproof membrane of the present invention, the setting of polyethylene polypropylene fiber material layer has increased the tensile strength of waterproof membrane, anti-leakage, deformation adaptability is strong, and the setting of POE plastic layer makes waterproof membrane More toughness and elasticity, good waterproof effect, good toughness, can prevent the breakage of the waterproof membrane, improve the poor deformation resistance of the waterproof membrane and adaptability to temperature changes, and ensure the overall waterproof performance of the waterproof membrane .

Description

technical field [0001] The invention relates to the technical field of engineering waterproof materials, in particular to a polyethylene polypropylene fiber composite waterproof coiled material. Background technique [0002] Waterproof materials play an important role in building construction. In the construction of roads, bridges, roofs or buildings that need to be waterproofed, a large amount of waterproof materials need to be paved to prevent leakage. Waterproof membrane is a kind of flexible building material product that can be rolled into a roll. As a non-leakage connection between the engineering foundation and the building, it is the first barrier for waterproofing the entire project and plays a vital role in the entire project. In engineering construction, waterproofing is an important item, and its quality directly determines the quality of the project. [0003] At present, PVC waterproofing membranes are mainly used in single-layer roof waterproofing membranes an...

AI Technical Summary

Problems solved by technology

[0003] At present, PVC waterproofing membranes are mainly used in single-layer roof waterproofing membranes and waterproofing of underground projects. Among them, single-layer roof waterproofing technology adopts mechanical fixing method for construction, the cost of accessories is high, and the construction speed is slow. The professional level of the construction personnel is high; similar asphalt-based self-adhesive coils corrode the polymer sheet layer, so direct self-adhesive construction cannot be carried out, and the weather resistance cannot reach the same lifespan as the polymer sheet

This kind of waterproof membrane generally has low tensile strength, poor impermeability, and short service life.
