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 discloses an ethylene-propylene-diene monomer rubber waterproof roll. The ethylene-propylene-diene monomer rubber waterproof roll is prepared from the following raw materials in parts by weight: ethylene-propylene-diene monomer rubber, DOP (Dioctyl-Phthalate) thermal welding agent, carbon black, light calcium carbonate, stearic acid, zinc oxide, rubber accelerator, sulfur, processing oil, fire-retardant plasticizer, chlorinated polyethylene (CPE), white carbon black and rubber accelerator tetramethyl thiuram disulfide (TMTD). A production method of the ethylene-propylene-diene monomer rubber waterproof roll comprises the steps of banburying, filtering, compounding, thermal cracking, calendering, rolling, vulcanization and packaging. The ethylene-propylene-diene monomer rubber waterproof roll produced by the method has good ageing resistance, small possibility of cracking and good waterproof effect and has an inflaming retarding function, the initiation temperature exceeds 300 DEG C, and the ethylene-propylene-diene monomer rubber waterproof roll has no water-permeating phenomenon through permeable experiments.

Description

technical field [0001] The invention relates to a building waterproof coating, in particular to a EPDM waterproof roll [0002] materials and their production methods. Background technique [0003] EPDM membrane is recognized as the waterproof membrane with the best comprehensive performance in the world. Carlyle Company of the United States established a branch in China in 1987. Imported EPDM began to be widely used in China because of its excellent physical properties. [0004] Construction project application. 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 p...
