Edge covering rubber for new energy automobile battery, and manufacturing method thereof

The invention discloses an edge covering rubber for a new energy automobile battery, and a manufacturing method thereof. The edge covering rubber is prepared from, by weight, 100 to 120 parts of methyl vinyl silicon-based rubber, 5 to 15 parts of cerium-containing polysiloxane, 0.5 to 2 parts of 2, 5-dimethyl-2, 5-bis, 1 to 5 parts of tert-butylperoxy, 3 to 10 parts of 2, 5-bis (tert-butylperoxy) hexane and 1 to 5 parts of white carbon black. The invention relates to the technical field of rubber processing. The edge covering rubber for the new energy automobile battery solves the problems that in the use process of the new energy automobile battery, a large amount of heat is usually generated, all mechanical properties of the edge covering rubber for the new energy automobile battery become poor in a high-temperature atmosphere, and the long-time service life becomes short. 本发明公开了一种用于新能源汽车电池用包边橡胶及其制造方法，按重量组分配比包括有以下成分：甲基乙烯基硅基胶100-120份、含铈聚硅氧烷5-15份、2，5-二甲基-2，5-双0.5-2份、叔丁基过氧基1-5份、双二五硫化剂3-10份、白炭黑1-5份，本发明涉及橡胶加工技术领
