苯基羟基硅油及其制备方法和应用
摘要：
本发明公开了一种苯基羟基硅油及其制备方法和应用。该苯基羟基硅油结构式为HO(R2SiO)a(R’C6H5SiO)bOH，其中300≤a≤550，100≤b≤150，且均为整数，R为甲基或乙基，R’为甲基或乙基。其在25℃常压下折光系数为1.45-1.47，粘度为3000-10000mPa.s。该苯基羟基硅油可作为基胶制备高透明高强度缩合型液体硅橡胶，以纳米SiO2为补强剂可制得透光率≥82％(680nm，2nm)，拉升强度大于5.4MPa，断裂伸长率大于148％的缩合型液体硅橡胶材料。
摘要（英）：

The invention discloses phenyl hydroxyl silicon oil and a preparation method and application thereof. The structural formula of the phenyl hydroxyl silicone oil is HO (R2SiO) a (R'C6H5SiO) bOH, wherein 300<=a<=550, 100<=b<=150, a and b are integers, R is methyl or ethyl, and R' is methyl or ethyl. The refraction coefficient at 25 DEG C and normal pressure is 1.45-1.47, and the viscosity is 3000-10000 mPa.s. The phenyl hydroxyl silicon oil can serve as base to prepare high-transparency high-strength condensed type liquid silicone rubber, nanometer SiO2 is used as a reinforcing agent, and therefore the condensed type liquid silicone rubber can be prepared, wherein the light transmittance is larger than or equal to 82% (680 nm, 2nm), the tensile strength is larger than 5.4 MPa, and the elongation at break is larger than 148%.
