Abstract

The invention relates to the field of rubber and discloses a foam rubber composition, vulcanized rubber and a preparation method and application thereof. The foam rubber composition contains a rubbermatrix, a reinforcing agent, a vulcanizing agent, a vulcanization accelerator, a vulcanization activator and a foaming agent, wherein the rubber matrix contains nitrile-butadiene rubber, polyvinyl chloride and halogenated butyl rubber, and every 100 parts of rubber matrix contains 3-20 parts of halogenated butyl rubber. The preparation method of the vulcanized rubber includes: mixing various components in the foam rubber composition, and vulcanizing the obtained mixed rubber. The vulcanized rubber is low in density, uniform in foam pores and evident in low-temperature resistance while the mechanical performance is guaranteed.

Description

technical field

[0001] The invention relates to the field of rubber, in particular to a foamed rubber composition, a vulcanized rubber and a preparation method and application thereof. Background technique

[0002] Since the 1950s, the molding process of blending nitrile rubber and polyvinyl chloride (NBR / PVC) rubber and plastic has been developed and perfected. The combination of NBR / PVC rubber and plastic blends can not only reflect the excellent elasticity and oil resistance of NBR, but also combine the excellent ozone resistance and chemical resistance of PVC.

[0003] In general, when rubber is used alone as the main frame material, the foam material has a large shrinkage rate but good elasticity; when resin is used alone as the main frame material, the foam material has poor elasticity but small shrinkage rate. The foamed material prepared by rubber-plastic blending has properties such as flexibility and lightness, which are better than those prepared by a single poly...
