Rubber and preparation method thereof

Abstract

The invention relates to rubber and a preparation method thereof. The rubber comprises ethylene-propylene-eiene monomer raw rubber, softening agents and filling agents, wherein polyethylene glycol is also contained in the rubber, and the flash point of the polyethylene glycol is between 160 and 175 DEG C. Rubber sealing strips prepared by the rubber disclosed by the invention have good sound insulation, shock absorption and sealing performance and good mechanical property. Meanwhile, the sealing strips have low intensity and cater to the light weight trend of the sealing strips at present. Inaddition, the rubber has the advantages of simple preparation process and low cost.

Description

【Technical field】

[0001] The invention relates to a rubber and a preparation method thereof. 【Background technique】

[0002] With the increasing development and popularity of automobiles, automobile-related components have also been greatly developed. As the main component that isolates the compartment from the outside world, the role of automotive sealing strips is becoming more and more significant. Generally, the sealing strip is required to have good sound insulation, dustproof, vibration reduction and sealing performance.

[0003] In the prior art, automobile sealing strips are generally made of ethylene propylene diene monomer (EPDM), which has excellent weather resistance and excellent processing performance. Good performance, excellent mechanical properties. However, due to the compact structure of the EPDM sealing strip, it is usually also a compact rubber sealing strip, and the sound insulation and vibration reduction effects of the compact rubber sealing strip ...
