Problems solved by technology

[0006] However, people's understanding of EPDM reclaimed rubber is still insufficient. How to better apply EPDM reclaimed rubber is still being explored by various manufacturers.
According to investigations and visits, it is common for relevant companies to use EPDM reclaimed rubber only based on experience, regardless of its blending ratio, and only ask customers for certain performance requirements before mixing and using.
At present, there is no research report on the blending ratio of rubber hoses and sealing strips for automobiles.

Abstract

The invention discloses an ethylene propylene diene monomer rubber and EPDM reclaimed rubber co-used rubber composition, and a preparation method and application thereof. The ethylene propylene diene monomer rubber and EPDM reclaimed rubber co-used rubber composition comprises, by mass, 90-50 parts of ethylene propylene diene monomer rubber and 10-50 parts of R-EPDM. The ethylene propylene diene monomer rubber and EPDM reclaimed rubber co-used rubber composition may also comprise other components such as an accelerator or sulphur. By doping ethylene propylene diene monomer reclaimed rubber and other components in a raw rubber, an ethylene propylene diene monomer rubber and EPDM reclaimed rubber co-used rubber composition that has excellent physical properties, has greatly reduced cost and can be widely applied in automobile engineering materials is developed.

Description

[0001] technical field [0002] The invention belongs to the field of macromolecular materials, and in particular relates to a combined rubber composition of EPDM rubber and EPDM reclaimed rubber, a preparation method and application thereof. [0003] Background technique [0004] China is a big consumer of raw rubber, and it is also a big country with a shortage of raw rubber resources. Finding the source of rubber raw materials and their substitute materials has become one of the important tasks for the Chinese people. Therefore, reclaimed rubber has gradually attracted the attention of relevant enterprises and has been widely used. On the one hand, it can replace rubber and alleviate the serious shortage of synthetic rubber and natural rubber; The problem of polluting the environment. [0005] Reclaimed rubber is cheap and has many types, among which EPDM reclaimed rubber (English: R-EPDM) is a rubber substitute material that has been used in large quantities in recent ...
