摘要
Abstract
Vi-MQ silicone resins with different M/Q ratios were successfully prepared through hydrolysis and condensation using raw materials including tetraethyl orthosilicate,hexamethyldisiloxane,vinyldimethylethoxysilane,glacial acetic acid,etc.The structure and thermal properties of the synthesized Vi-MQ silicone resins were characterized by FT-IR,1H-NMR,and TGA,confirming the successful synthesis of the target resins.Solvent-free silicone pressure-sensitive adhesives(PSAs)were prepared by blending the synthesized Vi-MQ silicone resins with silicone oils.The effects of factors such as the M/Q ratio of the Vi-MQ resin,resin content,viscosity of the silicone oil,and Si-H ratio on the properties of the silicone PSAs were systematically investigated.The results indicated that the overall performance of the PSA was optimized when the M/Q ratio was 0.8,the resin content was 50%,a vinyl silicone oil with a viscosity of 200 mPa·s and a hydroxyl silicone oil with a viscosity of 500 mPa s were used,and the Si-H ratio was 1.5.Under these conditions,a 180 °peel strength of 19.32 g/25 mm and a holding time of 7.42 h were achieved.关键词
