热固性硅橡胶以耐低温、耐热、柔性、表面惰性、耐水、抗化学腐蚀等性能突出而受到重视。但又存在固化时间长,强度低,对极性物表面粘结性差等缺点,使应用受到限制。近年来光敏性聚合物的研究与开发引人注目,利用电子束或紫外光固化的聚合材料,具有固化时间短、性能好,能耗低,少污染的优点。研究能快速光固化,又具备热固性硅橡胶性能的有机硅光敏性予聚物代替热固性硅橡胶,用这种聚合材料作石英光纤涂复材料,能提高
Thermosetting silicone rubber to low temperature, heat, flexibility, surface inertness, water resistance, chemical resistance and other prominent performance and attention. However, there is a long curing time, low strength, poor adhesion to the polar surface defects, so that the application is limited. In recent years, the research and development of photosensitive polymers attracts attention. The use of electron beam or ultraviolet curing polymeric materials has the advantages of short curing time, good performance, low energy consumption and less pollution. The research can be fast light-cured, but also has the thermosetting silicone rubber properties of silicone photosensitive prepolymer instead of thermosetting silicone rubber, with this polymeric material for quartz optical fiber coating material, can improve
