Problems solved by technology

[0002] 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, so many asphalt self-adhesive waterproofing membranes on the market are mixed with good and bad people, resulting in poor waterproof quality. There is no guarantee; at this stage, people's requirements for environmental protection are becoming more and more stringent, 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; The requirement for waterproofing life is getting higher and higher, and the weather resistance of asphalt is very limited; in addition, due to the heavy weight of the traditional waterproof membrane, it brings great difficulty to storage and construction. Stirring needs to be heated to about 200°C, which increases energy consumption and causes great environmental pollution

Abstract

The invention provides a modified non-asphalt-base self-adhesion waterproof coiled material with floating beads. The modified non-asphalt-base self-adhesion waterproof coiled material is characterizedby comprising, by weight, 15-48% of electron-rich system softening oil (which is a mixture, contains large pi bonds and accordingly is an electron-rich system), 0.5-6% of hot melt adhesive grade elastomers, 2-10% of styrene-butadiene-styrene block copolymers, 1-5% of tackifying rubber, 5-20% of waste rubber elastomers, 0.1-0.5% of anti-ultraviolet agents, 3-8% of high-temperature resin, 8-20% oftackifying resin, 0.1-0.2% of interfacial agents, 5-30% of floating beads and 5-15% of waste edible oil. The electron-rich system softening oil, the hot melt adhesive grade elastomers, the styrene-butadiene-styrene block copolymers, the tackifying rubber, the waste rubber elastomers, the anti-ultraviolet agents, the high-temperature resin, the tackifying resin, the interfacial agents, the floatingbeads and the waste edible oil are prepared to obtain the modified non-asphalt-base self-adhesion waterproof coiled material.
