Problems solved by technology

However, the non-polar structure of butyl rubber molecules causes it to be like natural rubber, which does not possess sufficient oil resistance (see the first volume of "Rubber Industry Handbook", Chemical Industry Press, the second edition in September 1989, P477- 487)

Abstract

This invention discloses an oil-resistant butyl rubber composition. The butyl rubber composition comprises: a blend of butyl rubber and acrylonitrile-butadiene rubber, alkyl phenolic resin as co-curing agent, and SnCl2 as activator. The content of acrylonitrile in the acrylonitrile-butadiene rubber is 23-30 wt. %. The wt. ratio of butyl rubber to acrylonitrile-butadiene rubber is (85-75) :( 15-25).

Description

technical field [0001] The present invention relates to a composition based on polymer elastomer material and its compounding technology, in particular, to an oil-resistant butyl rubber composition with butyl rubber itself having high damping characteristics as the main material and Its matching technology. Background technique [0002] With the continuous improvement of human living standards, people's requirements for the environment are getting higher and higher, and the rapid development of science and technology has prompted the continuous increase of the power of machinery and equipment, and the acceleration of operation speed, resulting in vibration and noise hazards. It is becoming more and more prominent, because vibration and noise will not only affect the service life of machinery and equipment and cause early damage to equipment, but also have a harmful impact on people's work efficiency and physical and mental health. An effective means to deal with such vibrat...
