description | The invention discloses low-viscosity methyl vinyl silicon oil and a preparation method thereof. The preparation method comprises the following steps: weighing 100 weight portions of methyl cyclosiloxane, 10-50 weight portions of tetravinyl tetramethylcyelo tetrasiloxane, 5-15 weight portions of hexamethyldisiloxane, 0-10 weight portions of vinyl dual-head, 0.01-0.03 weight portions of polymerization inhibitor, and 0.3-2 weight portions of alkaline catalyst, putting all the components in a reaction container, heating up to 90-120 DEG C, reacting for 2-8 h to obtain a reaction solution; cooling, adding a diluted acid solution for neutralization, adjusting the pH value to 7.0, washing with water 3 times, carrying out centrifugation to obtain crude silicone oil, and carrying out pressure reduction on the crude silicone oil at a temperature of 95 DEG C to remove low-boiling-point substance to obtain the low-viscosity methyl vinyl silicon oil. The methyl vinyl silicon oil prepared by the method has the characteris |
