Problems solved by technology

[0002] Non-substrate thermally conductive double-sided adhesive tape is a kind of tape that is directly coated on the release paper without coating any substrate. It has excellent waterproof performance, good processability, good temperature resistance, dimensional stability, Good thermal stability, chemical stability, good initial tack and long-lasting tack, etc., are widely used in the electronics industry. Due to the poor thermal conductivity of existing double-sided adhesives without substrates, electronic products have poor heat dissipation capabilities and shortened lifespans.

Abstract

The invention discloses a substrate-free heat-conducting double-faced adhesive tape which comprises an adhesive tape and release films, wherein both sides of the adhesive tape are provided with the release films; the adhesive tape is composed of a colloid matrix and a heat-conducting material; and the colloid matrix is pressed into a sheet. The substrate-free heat-conducting double-faced adhesive tape has the advantages of high reliability, favorable heat conductivity, high temperature resistance, low price and the like, is convenient to manufacture, easy for adhesion and convenient die cutting, and has wide market prospects in electronic industry.

Description

technical field [0001] The invention relates to the field of adhesive tapes, in particular to a substrate-free heat-conducting double-sided adhesive. Background technique [0002] Non-substrate thermally conductive double-sided adhesive tape is a kind of tape that is directly coated on the release paper without coating any substrate. It has excellent waterproof performance, good processability, good temperature resistance, dimensional stability, Good thermal stability, chemical stability, good initial tack and long-lasting tack, etc., are widely used in the electronics industry. Due to the poor thermal conductivity of existing double-sided adhesives without substrates, electronic products have poor heat dissipation capabilities and shorten their lifespan. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a thermally conductive double-sided adhesive without base material, which can improve the thermal conductivity ...
