Pugging type silicon rubber structured control agent

[0028] Example 1

[0029] Take 310g of DMC and perform vacuum distillation to remove 14g of DMC and water, then add 105g of methyl vinyl dimethoxy silane, stir evenly, heat to 100 ℃, add 21g of granular activated clay, stir and react at constant temperature for 1 hour, then slowly Warm up to 120℃ and continue to stir and keep the reaction for 3 hours, then cool to normal temperature, filter to remove activated clay, filtrate 120℃, -0.1Mpa vacuum distillation to remove 30g of low molecular substances, finally get 364g colorless, transparent liquid, its viscosity 6.5mm 2 / s, the methoxy group content is 8.82% (the methoxy group content is a weight percentage, the same hereinafter), and the vinyl content is 14.0% (the vinyl content is a mole percentage, the same hereinafter).

[0030] Example 2

[0031] Take 310g of DMC and perform vacuum distillation to remove 14g of DMC and water, then add 128g of methyl vinyl diethoxy silane, stir evenly and then heat to 120°C, add 21g of granular activated clay, stir for 4 hours and cool to room temperature. , Filter to remove activated clay, the filtrate is distilled under reduced pressure at 120°C and -0.1Mpa to remove 32g of low-molecular substances, and finally 384g of colorless and transparent liquid with a viscosity of 7.0mm 2 / s, the ethoxy content is 12.8%, and the vinyl content is 13.8%.

[0032] Example 3

[0033] Take 310g of DMC and perform vacuum distillation to remove 14g of DMC and water, then add 105g of methyl vinyl dimethoxy silane, stir evenly, heat to 100 ℃, add 21g of granular activated clay, stir and react at constant temperature for 1 hour, then slowly Warm up to 120°C and continue to stir and keep the reaction for 3 hours, then cool to 64°C, add 24g of water to 78°C and keep the reaction for 3 hours, cool to room temperature, filter to remove the activated clay, and remove the filtrate by distillation under reduced pressure at 120°C and -0.1Mpa 25g low-molecular substances, finally get 390g colorless, transparent liquid with a viscosity of 11.0mm 2 / s, the hydroxyl content is 3.02%, the methoxy content is 5.29%, and the vinyl content is 13.2%.
