Flame-retardant EPDM rubber/POE waterproof coiled material and preparation method thereof

Abstract

The invention provides a flame-retardant ethylene-propylene-diene monomer (EPDM) rubber / POE waterproof coiled material. The coil material is characterized by being prepared from the following raw materials in parts by weight: EPDM rubber, nitrile silicone rubber, POE, 1,3-bi(tertiary butyl peroxide diisopropyl)phenyl, triallyl isocyanurate, stearic acid, 2-mercapto benzimidazole, lanthanum oxide, polyethylene glycol, caprolactone, polyoxyethylene octylphenol ether, zinc oxide, trimethyl phosphate, isopropyl tri(dodecyl benzenesulfonyl)titanate, graphite, 3,3,4,5-tetrachloro salicylamide, ammonium dihydrogen phosphate, micro-capsule red phosphorus, 2.2'-disulfbenzothiazole, and deionized water. According to the flame-retardant EPDM rubber / POE waterproof coiled material, flame-retardant EPDM rubber is utilized as the base body, and the graphite is dispensed in the EPDM rubber base body, so that spreading of fire can be stopped; the ammonium dihydrogen phosphate and the micro-capsule red phosphorus are added to effectively delay firing and reduce the fire spreading speed; and after external flame leaves away, the self combusted flame can be quickly and automatically extinguished.

Description

technical field [0001] The invention relates to a building waterproof material, in particular to a flame-retardant 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 have good wat...

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
