以α,ω-二羟基聚二甲基硅氧烷(107硅橡胶)、交联剂、催化剂、偶联剂为原料,制得脱醇型单组分室温硫化(RTV-1)硅橡胶。考察了107硅橡胶的黏度、交联剂用量、催化剂种类、偶联剂类型和用量对脱醇型RTV-1硅橡胶硫化速度的影响。结果表明,当107硅橡胶的黏度为60000 mPa· s,交联剂用量为4%,1%的钛酸酯配合物1作为催化剂,偶联剂KH-792的用量为0.3%时,制得的脱醇型RTV-1硅橡胶具有较好的硫化速度,表干时间为15 min,8 h硫化深度为1.32 mm,24 h硫化深度为2.24 mm。
以α,ω-二羥基聚二甲基硅氧烷(107硅橡膠)、交聯劑、催化劑、偶聯劑為原料,製得脫醇型單組分室溫硫化(RTV-1)硅橡膠。攷察瞭107硅橡膠的黏度、交聯劑用量、催化劑種類、偶聯劑類型和用量對脫醇型RTV-1硅橡膠硫化速度的影響。結果錶明,噹107硅橡膠的黏度為60000 mPa· s,交聯劑用量為4%,1%的鈦痠酯配閤物1作為催化劑,偶聯劑KH-792的用量為0.3%時,製得的脫醇型RTV-1硅橡膠具有較好的硫化速度,錶榦時間為15 min,8 h硫化深度為1.32 mm,24 h硫化深度為2.24 mm。
