Abstract

The invention provides a high-adhesion antistatic paint for electronic components. The high-adhesion antistatic paint comprises the following components (by weight): 50-70 parts of polytetrafluoroethylene, 30-50 parts of an organic polymer composite material, 20-30 parts of a pigment, 5-10 parts of a filler, 5-10 parts of a curing agent, 4-6 parts of an insulating agent, 1-3 parts of a dispersingagent, 1-3 parts of a leveling agent, 1-3 parts of a drier, 1-3 parts of a plasticizer, 1-3 parts of a coalescing agent, and 100 parts of a solvent gasoline. The invention also provides a method for preparing the above high-adhesion antistatic paint for electronic components. The preparation method of the high-adhesion antistatic paint for electronic components is simple and is prepared by compounding of polymer and nano-alumina. On one hand, the adhesion is improved by the use of long oil alkyd resin for compounding; and on the other hand, corrosion resistance and electrical conductivity arevery excellent.

Description

technical field [0001] The invention relates to the field of powder coating materials, in particular to an antistatic coating with high adhesion for electronic components and a preparation method thereof. Background technique [0002] With the development of science and technology, all walks of life such as petroleum, chemical industry, and medical treatment are more and more inclined to mechanization and electronics. These factors make the harm of static electricity in society more and more dominant. Static electricity is easy to accumulate on the surface of metal and non-metallic materials, which can cause malfunctions in the operation of instruments and equipment, or break down electronic components, causing accidents such as electric shock, fire or explosion. Therefore, the anti-static requirements of electronic components and equipment are getting higher and higher. [0003] At present, there are many anti-static technical methods. Compared with electroplating and vacu...
