摘要
以丙烯酸丁酯(BA)、丙烯酸异冰片酯(IBOA)为软单体,甲基丙烯酸甲酯(MMA)、丙烯酸甲酯(MA)为硬单体,丙烯酸(AA)、丙烯酸羟乙酯(HEA)为功能单体,过氧化二苯甲酰(BPO)、偶氮二异丁腈(AIBN)为引发剂,乙酸乙酯为溶剂,添加硅烷偶联剂,制备了电子显示屏防爆膜用溶剂型丙烯酸酯压敏胶。采用单因素试验法探讨了软硬单体配比、功能单体用量、引发剂用量、硅烷偶联剂用量、丙烯酸异冰片酯用量对压敏胶黏度、180°剥离力、透光率、抗反弹性能的影响。研究结果表明:对于电子显示屏防爆膜用溶剂型丙烯酸酯压敏胶,软硬单体配比、功能单体的用量对压敏胶的180°剥离力和抗反弹性能影响较大;适量的硅烷偶联剂可以提升压敏胶对玻璃基板的粘接性能;适量的丙烯酸异冰片酯单体可以明显改善防爆膜胶带产品的透光率。目前所研发的压敏胶胶水及防爆膜胶带产品已开始批量化生产。
Solvent-based acrylate pressure sensitive adhesive for explosion-proof film of electronic display screen was prepared by using butyl acrylate(BA)and isobornyl acrylate(IBOA)as soft monomers,methyl methacrylate(MMA)and methyl acrylate(MA)as hard monomers,acrylic acid(AA)and hydroxyethyl acrylate(HEA)as functional monomers,benzoyl peroxide(BPO)and azobisisobutyronitrile(AIBN)as initiators,ethyl acetate as solvent,and adding silane coupling agent.The single factor experimental method was used to investigate the effects of soft and hard monomer ratio,functional monomer dosage,initiator dosage,silane coupling agent dosage,and isobornyl acrylate dosage on the viscosity,180°peeling force,transmittance,and rebound resistance of pressure sensitive adhesive.The research results showed that,for solvent-based acrylate pressure sensitive adhesive used in explosion-proof film for electronic display screen,the ratio of soft and hard monomers and the amount of functional monomers had the significant impact on the 180°peeling force and rebound resistance of pressure sensitive adhesive.An appropriate amount of silane coupling agent could enhance the bonding performance of pressure sensitive adhesive to glass substrates.An appropriate amount of isobornyl acrylate monomer could significantly improve the light transmittance of explosion-proof film tape products.At present,the developed pressure sensitive adhesive and explosion-proof film tape products had entered mass production.
