This paper studied the synthesis of rubber accelerator DZ by rubber accelerator DM, dicyclohexyl amine and ammonia in the solvent of methanol.
采用促进剂DM和二环己胺为原料,以氨气为缚酸剂,用甲醇做溶剂合成橡胶硫化促进剂DZ。
The one step method was adopted in this study to synthesize aliphatic polyurethane with 4,4 methylene dicyclohexyl diisocyanate(HMDI), 1,4 butanediol(BDO) and poly (tetrahydrofuran)(PTMG).
The property of HA-1 vapor phase inhibitor was evaluated in laboratory. It showed that HA-1 has better protection for steel, copper and aluminium, compared with dicyclohexyl amine nitrite.
