Problems solved by technology

At present, the EPDM waterproof membranes sold in the market are basically produced according to the national polymer waterproof membrane standards. When used on buildings, they have good waterproof effects and long working life. The fly in the ointment is that : Both the EPDM waterproof membrane and the waterproof layer used to generate it are easy to burn when exposed to open flames, so there are certain safety hazards, especially not suitable for waterproof and anti-corrosion projects for buildings with high fire protection requirements Therefore, it is not ideal from the perspective of practicality and economy

Abstract

The invention relates to an asbestos fiber reinforced EPDM rubber/POE waterproof coiled material. The waterproof coiled material is characterized by being prepared from the following raw materials in parts by weight: EPDM rubber, butyl rubber, POE, 1,3-bis(tert-butyl peroxy diisopropyl)benzene, triallyl isocyanurate, stearic acid, 2-mercapto benzimidazole, lanthanum oxide, propanediol sebacate polyester, methyl triethoxysilane, citric acid, a crosslinking agent TAC, gamma-mercaptopropyl trimethoxysilane, polyoxyethylene octylphenol ether, zinc oxide, chloroplatinic acid, asbestos fiber, 8-10% sodium hydroxide solution, sodium lignin sulfonate, benzophenone imine, tributyl citrate, 2,2'-dithio-dibenzo thiazole and deionized water. Due to addition of non-inflammable asbestos fiber resistant to heat, water, acid and chemical corrosion, heat insulation and energy saving effect, flame resistance and weather resistance of the waterproof coiled material are enhanced.

Description

technical field [0001] The invention relates to a building waterproof material, in particular to an asbestos fiber-reinforced EPDM / POE waterproof coiled material and a production method thereof. technical background [0002] EPDM membrane is recognized as the waterproof membrane with the best comprehensive performance in the world, and EPDM has been used in a large number of Chinese construction projects because of its excellent physical properties. In recent years, with the advancement of social science and technology and the enhancement of people's awareness of environmental protection, the industry's requirements for building waterproof materials have changed from the previous single waterproof function to the multifunctional direction of long life, flame retardancy, and ozone aging resistance. At present, the EPDM waterproof membranes sold in the market are basically produced according to the national polymer waterproof membrane standards. When used on buildings, they ha...
