Abstract

A fabric internally-enhanced block polyolefin waterproof roll at least comprises two block polyolefin layers and a fabric enhancement layer, and the three structure layers are compounded into a whole. Each block polyolefin layer is an elastic body which comprises, by weight, 30-70 parts of block polyolefin, 30-70 parts of polyolefin, 20-90 parts of fire retardant, 1-2 parts of compatilizer, 3-6 parts of pigment, 0.3-0.6 part of antioxygen and 0.3-0.6 part of light stabilizer. The fabric internally-enhanced block polyolefin waterproof roll solves the problems that a common waterproof roll is high in hardness, the composite strength of an upper thermoplastic polyolefin layer and a lower thermoplastic polyolefin layer is low, and welded joints are not reliable after being used for a long time, and the waterproof roll has the advantages of being soft, high in composite strength, reliable in welded joints and the like, thereby being an advanced waterproof roll.

Description

technical field [0001] The invention relates to a waterproof coiled material. In particular, it relates to a novel fabric inner reinforced block polyolefin waterproof membrane. Background technique [0002] Thermoplastic polyolefin (TPO for short, the same below) material is a material containing only carbon and hydrogen. It has the advantages of environmental friendliness, easy processing, good low temperature performance, weldability, and good weather resistance. It is used in single-layer roofing systems. has been widely used. [0003] The single-layer roofing system is generally suitable for large-scale roofing such as supermarkets and factories, and has been widely used at home and abroad. Most of the commercially available TPO coils currently use copolymerized modified polypropylene as raw material, which was developed in the 1980s. Produced by traditional Ziegler-Natta catalyst, the molecular weight distribution is wide and contains a considerable part of low molecu...
