Problems solved by technology

At present, most of the thermally conductive tapes used in the electronics industry are imported from abroad, and the price is relatively high. Although there are a few companies in China that are developing and producing thermally conductive tapes, the products produced are not only high in cost, but also inferior in performance to foreign counterparts due to immature technology. Products, which are mainly manifested in that the thermal conductivity is too low, and some indicators of physical properties just meet or fail to meet the general requirements of the electronics industry
Thermal conductivity does not meet certain requirements

Abstract

The invention discloses a glass fiber cloth heat-conducting double-faced adhesive tape which is characterized by comprising a substrate (3) and heat-conducting adhesive layers (2), wherein the substrate (3) adopts a tabby glass fiber cloth layer; each heat-conducting adhesive layer (2) is formed by spreading a heat-conducting adhesive layer on one surface of the substrate by a scraper in a transfer coating mode; and the heat-conducting adhesive is a mixture of an acrylic pressure-sensitive adhesive, aluminum oxide powder, boron nitride powder, nano metal powder, nano graphite powder and a coupling agent. The adhesive tape disclosed by the invention has the advantages of favorable heat-conducting property, simple manufacturing technique and low cost.

Description

technical field [0001] The invention relates to a double-sided adhesive, in particular to a glass fiber cloth thermally conductive double-sided adhesive suitable for bonding, fixing and heat dissipation of materials such as LED and electronic industries. Background technique [0002] The development of science and technology and market demand make electronic devices develop in the direction of miniaturization, light weight, compact structure and efficient operation, which makes their heat dissipation effect the key to the miniaturization design of the whole machine. In order to ensure the stable operation of electronic devices or equipment, the generated heat needs to be exported in time. Therefore, higher requirements are placed on the quality, thermal conductivity, strength and stability of the heat dissipation material. So the thermal conductive tape came into being, which is used for electronic devices first, to export heat in time to ensure the normal operation of the ...
