摘要

以丙烯酸异冰片酯(IBOA)、丙烯酸十二酯(La)为单体,亚磷酸三苯酯(TPO)和1-羟基环己基苯基甲酮(184)为光引发剂,γ-甲基丙烯酰氧丙基三甲氧基硅烷(KH-570)为偶联剂,双官能脂肪族聚氨酯丙烯酸酯(YNW25)为低聚物,松香和氢化松香为增粘树脂,采用紫外光引发聚合的方法制备出了一系列光学胶样品。对该样品光学性能、压敏性能、耐老化性能等进行了测试,探讨最优的配方组合。结果表明:软硬单体配比m(La)∶m(IBOA)=5∶3,当低聚物YNW25质量含量为50%,增粘树脂配比m(松香)∶m(氢化松香)=1∶1,光引发剂配比m(TPO)∶m(184)=3∶4时,可制备出透光率达93.3%,初粘力达8.51N/25mm,180°剥离力达10.81N/25mm,保持力达16.51h,且耐老化性能优异的光学胶压敏胶膜。

Abstract

Using isobornyl acrylate (IBOA) and dodecyl acrylate (La) as monomers,triphenyl phosphite (TPO) and 1-hydroxycyclohexyl phenyl ketone (184) as photoinitiators,γ-methyl Acryloyloxypropyltrimethoxysilane (KH-570) as coupling agent,bifunctional aliphatic urethane acrylate (YNW25) as oligomer,rosin and hydrogenated rosin as tackifying resins,a series of optical adhesive samples were prepared by UV light-initiated polymerization.The optical properties,pressure-sensitive properties and aging resistance of the samples were tested,and the optimal formula combination was discussed.The best condition was:the ratio of soft and hard monomers was m(La)∶m(IBOA)=5∶3,the content of oligomer YNW25 was 50wt%,the ratio of tackifying resin was m(rosin)∶m(hydrogenated rosin)=1∶1,and the photoinitiator ratio was m(TPO)∶m(184)=3∶4.Under the optimal condition,a optical pressure-sensitive adhesive film with a light transmittance of 93.3%,a initial adhesion of 8.51N/25mm,a peeling force of 10.81N/25mm at 180°,a holding force of 16.51h,and excellent aging resistance could be prepared.
