Abstract

A preparation method of insulating paint with heat transfer function, comprising the following steps: preparation of base material, pretreatment of filler, preparation of liquid mixture, pretreatment of copper foil, coating, and imidization. The invention overcomes the disadvantage of poor thermal conductivity of the thermally conductive paint, is simple and practical, adopts a composite thermally conductive powder accumulation method, so that the insulating paint has high heat transfer performance and voltage breakdown resistance, and the cured paint film is subjected to voltage breakdown. Tests have verified that this insulating paint has excellent thermal conductivity and surface breakdown resistance; the compounded thermally conductive filler has high fluidity, is easy to disperse, the thickness of the paint film is controllable, the compound medium has no visible bubbles, and the process is simple Controllable, low scrap rate; the obtained polymer material is cheap, easy to process, low cost, and can be industrially produced.

Description

technical field [0001] The invention relates to the field of preparation of insulating paint with thermal conductivity, in particular to a preparation method of insulating paint with heat transfer function. Background technique [0002] With the development demand of high frequency and high energy consumption, thermal conductive materials are widely used in various fields. Generally, the thermal conductive materials are mostly metals such as Au, Ag, Cu, Al, Mg and hydroxides or oxides, as well as AlN, BN, SiC graphene, graphite, etc. The rapid development of industrial production and science and technology has put forward newer and higher requirements for thermally conductive materials. In addition to thermal conductivity, materials are expected to have excellent comprehensive properties such as light weight, easy processing and molding, good mechanical properties, and chemical corrosion resistance. For example, heat exchanger materials used in chemical production and waste...
