单组分RTV(室温硫化)硅橡胶的硫化反应是通过其与空气中的水分发生反应而硫化成弹性体的。根据交联剂与端羟基聚二硅氧烷进行交联反应时生成副产物的种类,可将缩合型单组分RTV液体硅橡胶分为脱酮肟型、脱醇型、脱丙酮型、脱乙酸型、脱胺型和脱酰胺型等6种。脱酮肟型、脱醇型是较常见的品种:前者粘
One-component RTV (room temperature vulcanization) vulcanization of silicone rubber is vulcanized into elastomers by reacting with moisture in the air. According to the cross-linking reaction of the cross-linking agent and the terminal hydroxyl-terminated polydisiloxane, byproducts can be formed, the condensation-type one-component RTV liquid silicone rubber can be divided into the keto-oxime type, the dealcoholization type, Acetic acid type, deamination type and deamidation type 6 kinds. De-ketoxime-type, alcohol-type is the more common species: the former sticky
