Abstract

The invention provides a preparation method of a polyethylene polypropylene fiber composite waterproof coiled material, which uses polyethylene polypropylene fiber composite waterproof coiled material preparation equipment, and the equipment comprises a mounting plate, a conveying and gluing device and a pressing and winding device. The method can solve the following problems in the preparation process of the polyethylene polypropylene fiber composite waterproof coiled material: a, most of the conventional polyethylene polypropylene fiber composite waterproof coiled material is not provided with self-adhesive glue, so that glue needs to be coated on the wall body in actual use, and then the polyethylene polypropylene fiber composite waterproof coiled material is paved on the wall body, the construction steps are multiple, and the working intensity is increased; and b, the surface of the existing traditional polyethylene polypropylene fiber composite waterproof coiled material is coated with self-adhesive glue in advance, so that the self-adhesive glue is not uniformly coated, gaps exist when the coiled material is paved on the wall body, the water leakage phenomenon still exists, and bubbles exist when isolation paper is attached to the surface of the coiled material.

Description

Technical field

[0001] The present invention relates to the preparation of waterproof web preparation, and more particularly to a polyethylene polypropylene composite waterproof web preparation method. Background technique

[0002] The asphalt or polymer waterproof material is immersed on the carcass and produced a waterproof material product, which is provided as a waterproof web. The waterproof web requires good water resistance, no flow of temperature changes, does not flow, does not blister, disclaimed; low temperature does not criticize, a certain mechanical strength, extensibility and anti-cracking, must have certain Flexibility and anti-aging. Waterproof coils are mainly used for building walls, roofs, and tunnels, roads, landfills, etc., which enrolls the outside rainwater, groundwater leakage, can be curled into a roll-shaped flexible building materials, as a foundation There is no leakage between the buildings, the first barrier for the entire project waterproof, which ...
