titleOfInvention | A kind of continuous preparation method of electronic grade methyl silicone oil |
abstract | The invention relates to a continuous preparation method of electronic grade methyl silicone oil. ; The raw materials are pre-mixed, and the pre-treated raw materials are input into the screw mixer according to a certain mass ratio for heat preservation and mixing; for polymerization, the pre-mixed materials are input into the first-stage static fluidized bed for pre-polymerization, and then into the second-stage static fluidized bed for equilibrium polymerization. The semi-finished product is obtained; the low-boiling product is removed, and the semi-finished product is sent to a thin-film evaporator for primary purification to remove low-boiling substances, and then sent to a short-path low-molecular-weight distiller for second-stage purification to obtain a finished product. The above is a continuous production process, the polymerization is stable and the conversion rate is high. The finished product index: the molecular weight distribution coefficient is small, the low boiler is less than 0.20%, the content of silanol is low, and the content of Na, K and heavy metal plasma is less than 10ppb, which can meet the requirements of electronic and micro Application requirements in electronics and other industries. |
