摘　　要：以聚酯丙烯酸酯(EB524)、环氧树脂(EP828)为基体树脂,丙烯酸胶液作为增黏树脂,并加入Tinuvin765受阻胺光稳定剂,制备光学透明压敏胶膜。通过对光学透明压敏胶膜的成膜性、持黏性能、透光率、折射率和耐老化性的测试,研究了基体树脂、增黏树脂和光稳定剂对压敏胶成膜性能的影响。结果表明:当mEB524∶mEP828为1∶5,增黏树脂和Tinuvin765受阻胺光稳定剂的质量分数分别为5%和0.5%时,制得的光学透明压敏胶膜成膜性和耐老化性较好,持黏性能优良,透光率达到90.24%,折射率达到1.514。With EB524 and EP828as matrix resin,acrylic resin glue as tackifying resin and adding Tinuvin765 hindered amine light stabilizer,an optical transparency（OCA）pressure sensitive adhesive film with good light transmittance and bonding strength was prepared.the influences of matrix resin,tackifying resin and light stabilizer on the properties of pressure sensitive adhesive film were discussed by testing the filmforming,holding stick properties,light transmittance,refractive index and resistance to aging.The results show that the OCA pressure sensitive adhesive film has better film-forming and resistance to aging,the holding stick properties are excellent.Its light transmission rate reaches 90.24%,refractive index reaches 1.514 when the mass ratio of EB524 and EP828is 1∶5,the mass fractions of tackifying resin and Tinuvin765 are 5% and 0.5%respectively.
