Low heat-generation rubber composition

摘要: PURPOSE: To obtain a rubber composition free from peptizing action to polymer and having remarkably improved heat-generation property without lowering abrasion resistance, by compounding natural and/or synthetic diene with reinforcing filler specific improving agent. CONSTITUTION: (A) 100pts.wt. of composed is compounded (B) 20W150pts.wt. such as carbon black, (C) 0.1W10pts.wt. one or more agents formula I II (R H methyl; n 3W11), e.g. γ-thiobutyrolactum, ω-thiolauric lactam, N-methyl-γ-thiobutyrolactam, 4- trifluoromethyl-2-thiouracil, etc., and, if necessary, (D) softener, an antioxidant, vulcanization accelerator, etc. COPYRIGHT: (C)1988,JPO&Japio
