Study on Effect of Different Phenyl Content on Performances of Silicone Rubber Cured With Polysilazane
Using polysilazane as the curing agent and curing with four kinds of silicone rubber with different phenyl content,the effect of phenyl content on the performance of silicone rubber cured with polysilazane was investigated.The results show that as the phenyl content increases,the glass transition temperature of the silicone rubber at low temperatures increases,the low-temperature crystallization performance of the silicone rubber decreases,and the damping performance of the silicone rubber is significantly improved.At room temperature,the tensile strength and elongation at break of silicone rubber are improved,but the hardness and deformation resistance of the material are reduced.
