Problems solved by technology

[0004] However, as the price of asphalt continues to rise; the technology of self-adhesive membranes is becoming more and more mature. Due to the increasingly mature technology, some small factories flood the market with a large number of defective products. There is no guarantee; at this stage, people have more and more strict requirements for environmental protection, and asphalt is a very complex substance, which contains many

Abstract

The invention discloses a self-adhesive waterproof material and a preparation method thereof. The waterproof material is composed of the following materials: 25-50% of softening oil, 0-5% of a hot melt adhesive elastic body, 1-9% of a styrene-butadiene-styrene block copolymer, 0-5% of a tackifying rubber, 8-18% of a waste rubber elastomer, 0.1-0.5% of a UV resistant agent, 5-8% of a high temperature resin, 10-25% of a tackifier resin, 0.1-0.15% of an interfacial agent, and 4-44% of a pigment filler. The waterproof material provided by the invention has excellent weather-proof and ageing-proof performance to solve the problem that a traditional asphalt coiled material loses waterproof effect with time and seasons, and has super stripping performance 2-3 times of that of the traditional asphalt coiled material, and can closely combined with the concrete to form a skin-type waterproof barrier.

Description

technical field [0001] The invention relates to the technical field of chemical waterproof materials, in particular to a self-adhesive waterproof material different from traditional asphalt-based materials and a preparation method thereof. Background technique [0002] The continuous update of waterproof technology has also accelerated the diversification of waterproof materials. Generally speaking, materials that prevent rainwater, groundwater, industrial and civil water supply and drainage, corrosive liquids, and moisture and steam in the air from intruding into buildings are basically collectively referred to as waterproof materials. For waterproof material. Waterproof materials are mainly divided into four categories: coiled materials, coatings, rigid materials and sealing materials. The present invention belongs to the class of coiled materials. As people have higher and higher requirements for the service life of buildings, and many buildings have reduced service lif...
