Preparation of Pressure Sensitive Adhesives Based on Visible Light-Cured Natural Rubber Latex
摘要
Abstract
Degraded natural latex was mixed with terpene resin emulsion and other additives and then cured under the visible light initiator system to prepare oil-in-water emulsion type of pressure-sensitive adhesive (PSA). The ratio of degraded natural rubber to terpene resin emulsion,molecular weight and amounts of other additives were measured to observe their effects on the properties of PSA under a given light intensity. The results showed that the PSA with optimum properties was prepared under the following conditions: the ratio of the degraded natural latex and terpene resin emulsion was 1:1,molecular weight of the degraded natural rubber latex 19.8×10~4,the amount of initiator 1.2%,the amount of cross-linker 15%,and the amount of accelerant 0.4%. The DSC and TG/DTG showed that the PSA was improved in thermal stability after the PSA containing photo-initiator was cured by visible light. The PSA containing photo-initiator showed an increase of 5℃ in Tg,and was still available under a very low temperature.关键词
