Problems solved by technology

However, as we all know, most of the components of electronic products will generate heat during operation. If the heat is not exported in time, it will affect the service life of components and increase the probability of product repair.
However, the existing adhesive tape only has the function of decoration and protection, and does not have the function of heat dissipation. In this case, long-term use will increase the load on components, cause certain damage, increase the probability of damage to components, and also Increased cost of use

Abstract

The invention provides a heat-conducting matt black adhesive tape and a preparation method thereof. The heat-conducting matt black adhesive tape sequentially comprises a matt ink layer, a black ink layer, a PI base material layer, a pressure-sensitive adhesive layer added with heat-conducting filler and a release film layer from outside to inside, wherein the thicknesses of the matte ink layer, the black ink layer, the PI substrate layer, the pressure-sensitive adhesive layer added with the heat-conducting filler and the release film layer are 1-10 microns, 1-10 microns, 4.5-100 microns, 1-50 microns and 25-100 microns respectively. The heat-conducting matt black adhesive tape can be rapidly prepared, has the effects of shading, fingerprint prevention, scratch prevention and the like, can increase the heat-conducting property while having viscosity, improves the heat conduction effect of the adhesive tape, and effectively solves the problems that in the prior art, the adhesive tape does not have a heat dissipation effect, components are easy to damage, the service life is short and the like.

Description

technical field [0001] The invention belongs to the technical field of adhesive tape preparation, and in particular relates to a heat-conducting matt black adhesive tape and a preparation method thereof. Background technique [0002] In electronic terminal products, a variety of materials involved require certain covering or beautifying effects. In this case, the surface of the tape needs to be treated with matte black to achieve light-shielding, anti-fingerprint and anti-scratch effects. However, as we all know, most of the components of electronic products will generate heat during operation. If the heat is not exported in time, it will affect the service life of the components and increase the probability of product repairs. However, the existing adhesive tape only has the function of decoration and protection, and does not have the function of heat dissipation. In this case, long-term use will increase the load on components, cause certain damage, increase the probabilit...
