Problems solved by technology

Waterproof membranes are often used to paste underground waterproofing with concrete cushions, but waterproof membranes cannot be directly bonded to the main underground structure, causing the waterproof layer to be separated from the main structure, so that the waterproof layer is easily damaged
Traditional waterproof self-adhesive materials will flow, rapidly age, and dry out under extreme conditions of repeated cold and heat alternation, resulting in shortened service life of waterproof materials in such extreme environments

Abstract

The invention discloses a waterproof self-adhesive coiled material prepared from butyl rubber. The coiled material is prepared from, by weight, 7-15 parts of the butyl rubber, 0.5-5 parts of carbon black, 10-16 parts of polyisobutene, 0.3-2 parts of resin, 2-8 parts of white oil, 60-80 parts of kaolin and 0.1-0.8 part of anti-aging agent. The invention further discloses a preparation method of the waterproof self-adhesive coiled material prepared from the butyl rubber. The waterproof self-adhesive coiled material prepared from the butyl rubber has the advantages of being good in chemical stability, good in aging resistance, capable of being used for a long time under the environmental condition of -40 DEG C-80 DEG C, capable of prolonging the service life, long in service life, environmentally friendly, safe, easy, convenient and rapid to use, good in air tightness and water tightness, strong in viscosity, capable of being firmly bonded with a building main structure and the like.

Description

technical field [0001] The invention relates to building waterproof materials, in particular to a butyl rubber waterproof self-adhesive coiled material and a preparation method thereof. Background technique [0002] Building waterproofing is an important part of construction engineering, and the quality of waterproofing projects directly affects the service life and safety of buildings. Waterproof membrane is a commonly used material in building construction and plays an important role in preventing leakage. Nowadays, the waterproof membrane is often used to paste the concrete cushion for underground waterproofing, but the waterproof membrane cannot be directly bonded to the underground main structure, causing the waterproof layer to be separated from the main structure, so that the waterproof layer is easily damaged. Traditional waterproof self-adhesive materials will flow, rapidly age, and dry out under extreme conditions of repeated alternating cold and heat, which will ...
