Preparation method and application of high-resilience EPO polymer material

Abstract

The invention discloses a high-molecular waterproof board for roads. Particularly, macromolecule waterproof materials used in tunnels, subways, high-speed rails and basement areas are all hard plasticplates. In a harsh environment, in order to solve the problems of insulation performance defect and difficult construction caused by size change in the prior art, the invention aims to provide a high-resilience EPO high polymer material which comprises the following raw materials: a toughening agent, linear low density polyethylene, homopolymerized PP, a mineral filler, a compatilizer, a modification assistant, an antioxidant and an anti-ultraviolet agent. The preparation method comprises the following steps: premixing the raw materials, extruding through double screws, carrying out three-roller calendering, eliminating internal stress through high and low temperature circulation, and carrying out corona treatment, drying, cooling, drawing and rolling to obtain the high-resilience EPO polymer waterproof board, which has the advantages of excellent mechanical properties, favorable flexibility, favorable weather resistance and excellent high resilience.

Description

technical field [0001] The invention belongs to the technical field of building waterproofing engineering, and in particular relates to a high-resilience polymer material, in particular to the preparation and application of a high-resilience EPO polymer material. Background technique [0002] Polymer waterproof materials used in roads in my country, especially those used in tunnels, subways, high-speed rail and basement areas, are mainly PE waterproof boards and EVA waterproof boards, which need to meet GB / T 18173.1-2012 standard high resistance Permeability, aging resistance, and excellent mechanical properties, etc., but the existing polymer waterproof sheets for road tunnels are all hard plastic sheets. There is a phenomenon of dimensional changes, which leads to insulation performance defects; at the same time, the performance of the material will attenuate after long-term use in harsh environments. The problem of good construction will affect the efficiency of constructio...
