AI Technical Summary

Problems solved by technology

Traditional EPDM coils are mostly bonded with adhesives and adhesive tapes. This bonding method has the disadvantage that the overlapping parts of the coils are not firmly bonded and cracks are prone to occur, which affects the overall waterproofing of the coils. effect, it can not form an overall waterproof layer, and at the same time, the construction environment must be dry, flat and firm when bonding, which limits the scope of use of EPDM membranes

Abstract

The invention discloses an EPDM (Ethylene-Propylene-Diene Monomer) rubber waterproof rolling material and a production method and a welding method thereof. The EPDM rubber waterproof rolling material is prepared from the following active ingredients in parts by weight: EPDM rubber, a DOP (Dioctyl-Phthalate) thermal welding agent, a reinforcing agent, a powder filler, an anti-aging agent, a catalyst, a rubber accelerator DM and a vulcanizing agent. The EPDM rubber waterproof rolling material prepared from the above raw materials in parts by weight is stable in physical and mechanical performances, good in durability and anti-aging capability, and has oil-resistant and solvent-resistant properties equivalent to universal chloroprene rubber; the EPDM rubber waterproof rolling material is good in heat resistance and cold resistance, and can be used in the range of -60 DEG C to 150 DEG C; the EPDM rubber waterproof rolling material has high tear strength and ductility, and is strong in adaptability to shrinkage or cracking of a building; the EPDM rubber waterproof rolling material is light in specific weight (0.90-0.97), even in appearance quality, and has good flexibility and elasticity; and the EPDM rubber waterproof rolling material is good in weldability, and the materials can be directly welded.

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 and their welding 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. Traditional EPDM coils are mostly bonded with adhesives and adhesive tapes. This bonding method has the disadvantage that the overlapping parts of the coils are not firmly bonded and cracks are prone to occur, which affects the overall waterproofing of the coils. As a result, it cannot form an overall waterproof layer. At the same time, the bonding requires that the construction environment must be dry, flat, and firm, which limits the s...
