Abstract

The utility model discloses a polyethylene-polypropylene composite waterproof coil. The polyethylene-polypropylene composite waterproof coil comprises a self-adhesion rubber waterproof layer; a non-woven fabric layer is coated on the self-adhesion rubber waterproof layer; a polyethylene octene elastomer (POE) plastic layer is coated on the non-woven fabric layer; a glass fiber layer is coated on the POE plastic layer; a polyethylene-polypropylene material layer is coated on the glass fiber layer; the polyethylene-polypropylene material layer, the glass fiber layer, the POE plastic layer, the non-woven fabric layer and the self-adhesion rubber waterproof layer are integrated through hot pressing; the thickness of the polyethylene-polypropylene material layer is 0.5 to 1.5 millimeters; the thickness of the self-adhesion rubber waterproof layer is 1 to 3 millimeters; the thickness of the non-woven fabric layer is 0.5 millimeters; due to the arrangement of the polyethylene-polypropylene material layer, the leakage resistance performance of the waterproof material is improved; due to the arrangement of the POE plastic layer, the waterproof material has toughness and elasticity; and the waterproof coil is good in waterproof effect and high in toughness and is prevented from being broken.

Description

A kind of polyethylene polypropylene composite of water-proof coiled material

Technical field

The utility model relates to a kind of waterproof material, relates to specifically a kind of polyethylene polypropylene composite of water-proof coiled material.

Background technology

Existing waterproof roll is by carcass and cover that waterproof membrane on side of carcass forms; What carcass generally adopted is the sheet materials such as glass fabric, polypropylene long fiber free-weaving fabric, fabric, nonwoven, is soaked with the waterproof materials such as pitch, rubber in carcass.This waterproof roll, general tensile strength, garden ball bursting strength, trap tear strength are lower, and anti-permeability performance is poor, and the life-span of use is shorter.

Summary of the invention

Problem to be solved in the utility model provides long service life, a kind of polyethylene polypropylene composite of water-proof coiled material of good water-proof effect.

In order to address the above problem, the utility model by the following technical solutions:

A kind of polyethylene polypropylene composite of water-proof coiled material, comprise the self-adhering rubber watertight composition, the top of described self-adhering rubber watertight composition is covered with nonwoven layer, the top of described nonwoven layer is covered with the POE plastic layer, the top of described POE plastic layer is covered with glass layer, the top of described glass layer is covered with the polyethylene polypropylene material layer, and polyethylene polypropylene material layer, glass layer, POE plastic layer, nonwoven layer and self-adhering rubber watertight composition are hot pressed into integrative-structure.

Below be to further improvement in the technical proposal:

The thickness 0.5-1.5 millimeter of described polyethylene polypropylene material layer; The thickness of self-adhering rubber watertight composition is the 1-3 millimeter; The thickness of nonwoven layer is 0.5 millimeter.

The polyethylene polypropylene material layer the leakage resistance that has increased waterproof material is set, the setting of POE plastic layer makes waterproof material more flexible and elasticity, the utility model good water-proof effect, good toughness prevents the fracture of waterproof material.

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
