【摘要】 采用FTIR研究了过氧化物预硫化天然胶乳(PPVL)胶膜在120℃时的空气老化过程.结果表明,随着老化时间的延长,PPVL胶膜橡胶分子链上羟基、羧基、羰基、醚的数量不断增加,在相应红外谱带吸收逐渐加强;甲基、次甲基则缓慢氧化降解.更多还原

【Abstract】 The air aging process of peroxide prevulcanized natural rubber latex(PPVL) film by FTIR at 120℃ wasstudied. The results showed that the numbers of hydroxyl, carboxyl carbonyl and ether in rubber molecular chains ofPPVL film increased constantly with the extending of aging time, and absorption in corresponding infrared bandgradually increased; while methyl and methylene oxidized degradation slowly.更多还原
