Abstract

The invention relates to an organic siloxane polymer material for electronic packaging. The organic siloxane polymer material comprises hydroxy-terminated polydimethylsiloxane, silane or siloxane containing at least two alkoxy groups, poly(methylphenylsiloxane) containing vinyl groups, hydrogen-containing silicone oil, a condensation catalyst, a platinum catalyst, a curing inhibitor and white carbon black, wherein the vinyl groups in poly(methylphenylsiloxane) are located at an end group and a side chain, and the mass content of the side-chain vinyl group is 3%-10% on the basis of the mass of the component. The organic siloxane polymer material can be applied to the field of electronic packaging and has the characteristics of good mechanical properties, high mechanical strength and excellent transparency.

Description

Technical field [0001] The invention involves a new type of silicone polymer material for electronic packaging, which belongs to the field of electronic electrical appliances. Background technique [0002] With the development of science and technology, the application of electronics is becoming more and more widely used, but its application environment is complicated, especially the development of electronic appliances is integrated, miniaturized, and modular development. Therefore, it has put forward higher requirements for its use stability.Factors affecting electronic electronics stability are mainly device moisture, dust pollution, invasion of corrosive substances, mechanical vibrations, external force damage, etc., and there is a problem of calorie transmission for devices with greater power.Therefore, technical measures need to be used to ensure the stability of the performance parameters of electronics, where polymer packaging is a common method.The packaging is the opera...
