【摘要】 本文以端羟基氢化液态聚异戊二烯橡胶(HLBH2000)为改进剂,对水性聚氨酯压敏胶进行改性研究。结果表明,当异氰酸酯指数(R值)为1.05,物质中硬段结构与软段结构的摩尔数之比(C/A值)为3.5,氢化液态聚异戊二烯橡胶用量为7.5%时,可以得到性能优异的聚氨酯水性压敏胶。更多还原

【Abstract】 Hydroxy-terminated liquid polyisoprene rubber(HLBH 2000) was used as modifier to modify waterborne polyurethane pressure-sensitive adhesive. The results showed that when the isocyanate index(R value) was 1.05, C/A value was 3.5, and hydrogenated liquid polyisoprene rubber was 7.5%, the waterborne polyurethane pressure-sensitive adhesive with excellent performance could be obtained.更多还原
