Abstract
The invention relates to a manufacture method of rubber used for a building shock-isolation support, which is performed by carrying out internal mixing, open mixing, sheet adding and sheet vulcanizing processes on natural rubber (NR), butadiene rubber (BR), S, an accelerator DM (2,2'-dibenzothiazole disulfide), an accelerator CZ (N-cyclohexyl-2-benzothiazole sulfenamide), ZnO, a coupling agent Si-69, carbon black N774 and N330, stearic acid (StA), an aromatic oil, protective wax, coumarone, an antiageing agent 4010NA (N-isopropyl-N'-phenyl-p-phenylenediamine), an antiageing agent RD (poly(1,2-dihydro-2,2,4-trimethyl-quinoline)) and an antiageing agent AW (6-ethoxyl-2,2,4-trimethyl-1,2-dihydroquinoline). According to the manufacture method, the use of a semi-efficient vulcanization system can well balance the performance of the rubber support during the low-temperature long-time vulcanization process; the combined use of the accelerators DM and CZ can well balance the relationship between the vulcanization characteristics and physical properties; and the appropriate combined use of natural rubber and butadiene rubber can improve anti-reversion properties and heat aging performance of the rubber.
