Description

【Technical field】 [0001] The invention relates to the technical field of polymer materials, in particular to a sealing strip composite material and a preparation method thereof. 【Background technique】 [0002] As a sealing product, the sealing strip can play the role of shock absorption, waterproof, sound insulation, heat insulation, dustproof, fixing, etc. Its basic material is mainly EPDM rubber. EPDM rubber is a kind of non-polar rubber with saturated main chain. It belongs to synthetic polymer material. It has outstanding ozone resistance, excellent weather resistance, good high temperature and low temperature resistance, and chemical resistance. It is resistant to a variety of polar solutes and has a low relative density, but it has a large amount of expansion in minerals and lubricating oils and poor oil resistance, so its durability is greatly limited. [0003] In order to enhance the durability of EPDM rubber and eliminate its shortcoming of oil resistance, using it...
