Bi-component silica gel for IGBT (Insulated Gate Bipolar Translator) and preparation method thereof

The invention relates to the field of silica gel, and particularly discloses bi-component silica gel for an IGBT (Insulated Gate Bipolar Translator) and a preparation method of the bi-component silica gel. The bi-component silica gel for the IGBT comprises the following raw materials in parts by weight: a component A comprising 98-100 parts of vinyl silicone oil and 0.1-2 parts of a catalyst; the component B is prepared from 40-50 parts of vinyl silicone oil, 35-45 parts of modified MQ silicon resin, 0.05-2 parts of side hydrogen-containing silicone oil and 0.01-0.2 part of an inhibitor. The silica gel disclosed by the invention is soft and elastic and has relatively excellent heat resistance, shock absorption and insulating properties. 本申请涉及硅凝胶领域，具体公开了一种IGBT用双组分硅凝胶及其制备方法。本IGBT用双组分硅凝胶包括以下重量份的原料：组分A包括：乙烯基硅油98-100份，催化剂0.1-2份；组分B包括：乙烯基硅油40-50份，改性MQ硅树脂35-45份，侧含氢硅油0.05-2份，抑制剂0.01-0.2份，本申请中的硅凝胶柔软、有弹性，具有较优的耐热、减震、绝缘性能。
