氧化改性SBS粘接性能的研究

Research for the adhesive property of oxidated modification in styrene-butadiene-styrene block copolymer

对SBS主链中丁二烯软链段的双键进行氧化反应,并引入极性基团进行化学改性。测试结果表明氧化改性后的SBS,主链的双键被打开,引入了极性基团,其T型剥离强度提高了71.44%。

The double bonds of the butadiene soft matrix in styrene-butadiene-styrene block copolymer （SBS） were oxidated reaction,and chemical modification was happened. The results showed that the double bonds were opened,and made the main chain to have high polarity. The T-peel strength was raised 71.44% after modified.
