Abstract

A bi-component heat-conducting gel for 5G communication comprises a component A and a component B, wherein the component A is prepared from organic silicon resin, filler, terminal group modified polyhedral oligomeric silsesquioxane and styryl silane; the component B is prepared from organic silicon resin, a catalyst, liquid rubber, filler, liquid crystal type epoxy resin modified organic silicon,polydiphenyl siloxane with specific functional groups at the two tail ends, nano shell-core structure powder grafted with a surface modifier and pigment. The invention further discloses a preparationmethod of the bi-component heat-conducting gel for 5G communication. The bi-component heat-conducting gel is packaged by double tubes, and the component A and the component B are mixed when the bi-component heat-conducting gel is used. The bi-component heat-conducting gel has good heat conduction performance, is convenient to repair, can be repeatedly used after repair, improves the repair efficiency and reduces the repair cost.

Description

【Technical field】 [0001] The invention relates to the field of a two-component gel material, in particular to a two-component thermally conductive gel for 5G communication with good thermal conductivity, easy repair and low cost and a preparation method thereof. 【Background technique】 [0002] With the development of 5G communication, while putting forward higher requirements for the integration of electronic components, it also requires electronic components to have higher sensitivity. However, highly integrated electronic components are prone to failure due to high temperature or vibration, and need to be repaired before they can continue to be used. The heat-conducting materials used in existing electronic components mainly include heat-conducting silicone grease, heat-conducting gel, and heat-conducting pads, which generally have defects such as inconvenient cleaning, easy damage, and need to be replaced with new materials after maintenance, which not only reduces mainte...
