A kind of adhesive EPDM waterproof membrane

Abstract

The invention provides an adhesive ethylene propylene diene monomer rubber waterproof coiled material mainly comprising, by weight: 38-43 parts of ethylene propylene diene monomer rubber, 13-16 parts of carbon black, 28-32 parts of a filler, 6-8 parts of an anti-aging agent, 1.5 parts of a catalyst, 2-4 parts of an accelerator, 2-3 parts of a vulcanizing agent, and 0.5-1 part of a nano-grade modifier. The material is obtained through internal mixer mixing, refining, filtering, extruding, and continuous vulcanization processing. The adhesive ethylene propylene diene monomer rubber waterproof coiled material provided by the invention has good compatibility with bonding agent, high elasticity, high tearing strength, excellent low-temperature performance, excellent water resistance, excellent ozone resistance; and excellent aging resistance. The rubber can be used in high-coldness and high-temperature environments, and various structural deformations, Also, the waterproof coiled material has good environment friendliness. During a construction process, construction period is short, and paving efficiency is high.

Description

technical field [0001] The invention relates to the technical field of waterproofing, in particular to an adhesive EPDM waterproof coiled material. Background technique [0002] At present, 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 used in a large number of Chinese construction projects due to its excellent physical properties. . Compared with other domestic waterproof materials, EPDM waterproof membrane has light weight, wide temperature range, excellent weather resistance, high tensile strength at break, high elongation at break, and strong adaptability to base expansion and cracking. And other characteristics, and no harmful substances are produced during production, construction and use, and can be recycled, and will not produce construction waste and other environmental protection, and this kind of mate...

Problems solved by technology

[0003] While improving the production technology of EPDM coils abroad, they attach great importance to the development and research of application technology and system supporting materials. my country has developed and applied EPDM coils since the 1980s. It has been more than 20 years, but in There is a big gap between the application technology and the advanced countries. Due to the lack of attention to the development and application of system supporting materials, there have always been problems in the sealing treatment of the lap joints of the waterproof layer of the membrane and the treatment of special-shaped parts such as detailed nodes, and have not been well received. The problem of water leakage caused by this problem occurs from time to time, which hinders the development of EPDM membrane waterproofing system in China.
