Preparation method of polyethylene polypropylene fiber composite waterproof coiled material

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 ...

Problems solved by technology

[0005] The invention provides a preparation method of polyethylene polypropylene fiber composite waterproof membrane, which can solve the following problems in the preparation process of polyethylene polypropylene fiber composite waterproof membrane: a. most of the current traditional polyethylene polypropylene fiber composite waterproof membranes do not have Self-adhesive, so in actual use, it is necessary to apply glue to the wall first, and then lay the polyethylene polypropylene fiber composite waterproof membrane on the wall. This method has many construction steps and increases the work intensity; b. Now Some traditional polyethylene polypropylene fiber composite waterproof membranes are coated with self-adhesive glue on the surface of the membrane in advance, and the self-adhesive glue is not evenly applied, resulting in gaps when laying on the wall, and there is still water leakage, and the release paper There are air bubbles when it is pasted on the surface of the roll material, and the release paper and the roll material are prone to front and rear misalignment, which leads to the failure of the self-adhesive glue at both ends of the roll material during actual use, and cannot be effectively laid on the wall
