Self-adhesion waterproof material

Abstract

The invention discloses a self-adhesion waterproof material which is prepared from the following raw materials in parts by weight: 25-50 parts of softening oil, 2-5 parts of hot melt adhesive grade elastomer, 2-6 parts of synthetic rubber, 30-55 parts of asphalt, 1-5 parts of p-phenylenediamine, 1-9 parts of styrene-butadiene-styrene block copolymer, 2-5 parts of tackifying rubber, 8-18 parts of waste rubber elastomer, 0.1-0.5 part of an anti-ultraviolet agent, 5-8 parts of high-temperature resin, 10-25 parts of tackifying resin, 0.1-0.15 part of an interface agent and 4-44 parts of pigments and fillers. The waterproof material is excellent in weather and ageing resistance, the defect that the waterproof effect of a conventional asphalt-based coiled material is invalid along with time and seasons is overcome, the waterproof material is very good in stripping performance which is 2-3 times that of the conventional asphalt-based coiled material, and the waterproof material is closely combined with 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. 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 life due to water erosion, so people pay more and more attention to the quality of wate...

Problems solved by technology

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 substances that are not friendly to the environment. Due to the existence of asphalt, it will affect environmental protection; people are concerned about waterproof The waterproof life of materials is getting higher and higher, and the weather resistance of asphalt is very limited; the above four conditions make the market urgently need to introduce a non-asphalt-based self-adhesive membrane that can solve the above four problems
