Limonene is an important subsidiary agricultural product obtained from orange peel that can also be prepared by microbial engineering, but its application degree of deep processing is relatively lower. By studying the application of limonene to silicone rubber, the application field of limonene has been expanded. Triethoxy (2-(4-methylcyclohex-3-en-1-yl)propyl)silane (LTES) was synthesized by a hydrosilylation reaction in the presence of Karstedt's catalyst using limonene and triethoxysilane as raw materials. FT-IR and 1H NMR were used to determine the structure of the product (LTES). Thereafter, a series of room temperature vulcanized (RTV) silicone rubbers was modified with the LTES cross-linking agent and hydroxy silicone oil under the catalytic action of dibutyltin dilaurate. The results showed that the tensile strength, elongation at break and heat resistance of the synthetic silicone rubber modified with LTES were significantly higher.

三乙氧基(2-(4-甲基环己基-3-烯-1-基)丙基)硅烷为新型交联剂的室温硫化硅橡胶的制备及性能

柠檬烯是从橙皮中获得的重要的辅助农产品,也可以通过微生物工程来制备,但是其深加工的应用程度相对较低。通过研究柠檬烯在硅橡胶中的应用,扩大了柠檬烯的应用领域。以柠檬烯和三乙氧基硅烷为原料,在Karstedt催化剂的存在下,通过氢化硅烷化反应合成了三乙氧基(2-(4-甲基环己基-3-烯-1-基)丙基)硅烷(LTES)。FT-IR和11 H NMR用于确定产物的结构(LTES)。此后,在二月桂酸二丁基锡的催化作用下,用LTES交联剂和羟基硅油对一系列室温硫化(RTV)硅橡胶进行了改性。结果表明,用LTES改性的合成硅橡胶的拉伸强度,断裂伸长率和耐热性明显更高。
