Abstract

The invention relates to a self-adhesive reactive ethylene-octene copolymer composite waterproof coiled material and a production method thereof. The self-adhesive reactive ethylene-octene copolymer composite waterproof coiled material is formed by superimposing and compounding a base layer, a surface layer and an anti-adhesive isolating layer, wherein the base layer is an ethylene-octene copolymer waterproof layer, the surface layer is a self-adhesive reactive butyl rubber layer, and the isolating layer is a PE (polyethylene) anti-adhesive isolating film; on the basis of 100 parts of ethylene-octene copolymer, the base layer comprises 50-110 parts of carbon black, 30-70 parts of superfine talc powder, 5-10 parts of calcium carbonate, 20-60 parts of a plasticizer, 2-10 parts of polyethylene glycol, 1-6 parts of dicumyl peroxide, 0.5-2.75 parts of a crosslinking agent and 1-3 parts of an anti-aging agent; and the surface layer comprises the main raw materials namely butyl rubber, polyisobutylene, amorphous alpha-olefin copolymer and viscosity increasing resin, and the surface layer comprises auxiliary materials namely desulfurization gypsum, bentonite, calcium stearate, lithium chloride, calcium chloride, a swelling agent and a crosslinking agent. The invention can realize molecular chain complete crosslinking of the ethylene-octene copolymer waterproof coiled material to improve the thermal stability of the material and can achieve the aim of self-repairing by stopping water with water.

Description

1. Technical field [0001] The invention relates to the field of building waterproof materials, in particular to a self-adhesive reactive ethylene-octene copolymer composite waterproof coiled material and a production method thereof. 2. Background technology [0002] In underground building structures, due to the soft foundation, uneven settlement, and high groundwater level, water leakage often occurs in underground structures. It is difficult to achieve the waterproof performance of concrete itself. According to previous studies, the concrete structure with micro-cracks of 0.02mm will begin to leak water. Therefore, for underground structures with high waterproof requirements, a continuous outer waterproof layer is a must. prepared conditions. The existing waterproof materials used for underground concrete structures are generally three types of waterproof products: polymer coils, asphalt coils and coatings. Among them, the coils are treated with base treatment agents or a...
