Embodiment 1
[0026] Add 20g of methyltriethoxysilane into a reaction bottle with a stirrer, add 6g of dilute hydrochloric acid containing 153uL / L of HCl, reflux at 80°C for 12h, and age at room temperature for 12h to settle the resin at the bottom of the bottle. Wash off the HCl with distilled water until pH=7 is neutral, pour off the upper layer of water, add 12g of ethanol after drying, and prepare a 20g concentration of 30% (mass fraction) polymethylorganosilsesquioxane solution, and analyze it by mass spectrometry The number average molecular weight was measured to be 900.
[0027] Hydroxymethyl silicone oil (viscosity at 20°C is 15-50mm 2 the s -1 ) is a product of Beijing Dingye Industry and Trade Co., Ltd., and the brand number is 203. Add 4 g of hydroxymethyl silicone oil into the 20 g of polymethylorganosilsesquioxane solution prepared above, and mix evenly to obtain a clear and uniform mixed solution. Among them, the weight ratio of hydroxymethyl silicone oil to polymethylorga...
Embodiment 2
[0033] Add 24g of phenyltrimethoxysilane into a reaction bottle with a stirrer, add 10g of dilute hydrochloric acid containing 153uL / L of HCl, reflux at 80°C for 24h, and age at room temperature for 48h to settle the resin at the bottom of the bottle. Wash off HCl with distilled water until the pH=7 is neutral, pour off the upper layer of water, add 12g of acetone after drying, and prepare a 20g concentration of 30% (mass fraction) polyphenylorganosilsesquioxane solution, and use mass spectrometry Its number average molecular weight was measured to be 1500. Hydroxymethyl silicone oil (viscosity at 20°C is 15-50mm 2 the s -1) is a product of Beijing Dingye Industry and Trade Co., Ltd., the brand name is 203, 2g of hydroxymethyl silicone oil is added to the 20g of polyphenylorganosilsesquioxane solution prepared above, and mixed evenly to obtain a clear and uniform mixed solution. Among them, the weight ratio of hydroxymethyl silicone oil to polyphenylorganosilsesquioxane is 0...
Embodiment 3
[0039] Add 26g of vinyltriethoxysilane into a reaction bottle with a stirrer, add 12g of dilute hydrochloric acid containing 153uL / L of HCl, reflux at 80°C for 24h, and age at room temperature for 48h to settle the resin at the bottom of the bottle. Wash off the HCl with distilled water until the pH=7 is neutral, pour off the upper layer of water, add 12g of tetrahydrofuran after drying, and prepare a 20g concentration of 30% (mass fraction) polyvinylorganosilsesquioxane solution, and analyze it by mass spectrometry The number average molecular weight was measured to be 2000. Hydroxymethyl silicone oil (viscosity at 20°C is 15-50mm 2 the s -1 ) is a product of Beijing Dingye Industry and Trade Co., Ltd., and the brand name is 203. Add 5 g of hydroxymethyl silicone oil to the 20 g of polyvinylorganosilsesquioxane solution prepared above, and mix well to obtain a clear and uniform mixed solution. Among them, the weight ratio of hydroxymethyl silicone oil to polyvinylorganosils...
