Abstract

Provided are a self-bonded macromolecular composite waterproof roll with a large waste rubber powder doping amount and a preparation method thereof. The self-bonded macromolecular composite waterproof roll is composed of an upper surface micro-crosslinking thermoplastic elastomer layer, an upper middle waste vulcanized rubber powder resin layer, a lower middle hot melting pressure-sensitive rubber layer and a bottom face isolating layer. The overall thickness ranges from 1.2 mm to 2.0 mm, the thickness of the micro-crosslinking thermoplastic elastomer layer accounts for 17% to 35% of the total thickness, the thickness of the hot melting pressure-sensitive rubber layer is 0.35 mm, the thickness of the isolating layer is 0.15 mm, and the rest is the waste vulcanized rubber powder resin layer. The self-bonded macromolecular composite waterproof roll is free of plasticizer, has high durability, high mechanical performance and prominent low-temperature flexibility, and meanwhile has the advantages of being excellent in waterproofness, thermal weldability and yellowing resistance, long in service life, convenient to construct and the like.

Description

technical field [0001] The invention relates to a polymer composite waterproof coiled material, in particular to a self-adhesive polymer composite waterproof coiled material with a high content of waste rubber powder. Background technique [0002] With the rapid development of my country's automobile industry and tire industry, my country has become the world's largest producer of tires, and tire production accounts for 1 / 3 of the world's production. However, at the same time, my country's waste tire recovery rate is low, and the application field is narrow. It is getting more and more serious, and the recycling and reuse of waste tire resources has been put on the agenda. [0003] At present, crushing waste vulcanized rubber products such as waste tires into vulcanized rubber particles (rubber powder), and then blending them with other polymers through rubber and plastic processing equipment to prepare new products is the main way of recycling. However, a large amount of th...
