Abstract

The invention discloses a double-component organic silica gel for packaging of a large power IGBT (insulated bipolar translator) and a preparation method thereof. The organic silica gel is prepared by mixing a component A and a component B, wherein the component A is prepared by mixing the following components in parts by weight: 100 parts of vinyl silicone oil and 0.02-1 parts of platinum catalyst, the component B is prepared by mixing the following components in parts by weight: 70-90 parts of vinyl silicone oil, 10-30 parts of chain extender (end of which contains hydrogen silicone oil), 0.5-5 parts of cross-linking agent (side chain of which contains hydrogen silicone oil), 0.1-1 part of inhibitor, and 0.05-0.5 parts of antioxygen. When the double-component organic silica gel is used, the component A and the component B are stirred and mixed uniformly according to weight ratio of 1 to 1 so as to be solidified to obtain the organic silica gel. The organic silica gel takes silicone oil of high purity as raw material, and has good heat stability, low volatile matter, and high dielectric strength, thus meeting the use requirement of a large power IGBT module.

Description

technical field

[0001] The invention relates to the technical field of silicone gel, in particular to a two-component silicone gel for encapsulating high-power IGBTs and a preparation method thereof, which can be used for the encapsulation of IGBT modules above 6000V. Background technique

[0002] With the increasingly sharp contradiction of power demand, the development and application of new power electronic devices has achieved rapid development, and IGBT (Insulated Gate Bipolar Transistor, insulated gate bipolar transistor) is one of the mainstream devices of new power electronic devices. Simply put, IGBT is a device that turns direct current into controllable alternating current. It has the advantages of high frequency, high voltage, and high current. It has a wide range of uses, especially high-power IGBT. Devices, traction drives, lighting circuits and other fields have been widely used.

[0003] Silicone gel is widely used in the potting and bonding of electronic co...
