Embodiment 1
[0037] Add 200 g of dimethylcyclosiloxane mixture, 120 g of tetramethyltetravinylcyclotetrasiloxane and 0.9 g of potassium hydroxide successively into the reaction kettle equipped with stirrer, thermometer and condenser tube, under nitrogen protection Raise the temperature to 150 o C. After constant temperature reaction for 3 h, after depressurized distillation to remove small molecular water, a transparent oily high-reactivity silicone oil was obtained.
[0038] Add 200 g of dimethylcyclosiloxane mixture, 8 g of allyltrimethoxysilane, 0.5 g of trimethylethoxysilane and 0.8 g of hydrogen into a reaction kettle equipped with a stirrer, a thermometer, and a condenser Potassium oxide, under the protection of nitrogen, the temperature was raised to 180 o C. After constant temperature reaction for 4 hours, after decompression distillation to remove small molecular water, a transparent oily thixotropic ultra-high molecular weight silicone oil was obtained, with a molecu...
Embodiment 2
[0043] Same as Example 1, but the amount of highly reactive silicone oil in step (4) is changed from 100 g to 120 g, the amount of thixotropic ultra-high molecular weight silicone oil is changed from 100 g to 80 g, and the others remain unchanged.
Embodiment 3
[0045] Same as Example 1, but the amount of highly reactive silicone oil in step (4) is changed from 100 g to 80 g, the amount of thixotropic ultra-high molecular weight silicone oil is changed from 100 g to 120 g, and the others remain unchanged.
