Abstract

The invention discloses wear-resistant anti-static paint and a preparation method thereof. The wear-resistant anti-static paint is prepared from the following raw materials: novolac epoxy resin, bisphenol A-type epoxy resin, tricresyl phosphate, zinc oxide crystal whisker, polysiloxane, talcum powder, mica powder and the like. The preparation method comprises the following steps: uniformly mixingthe novolac epoxy resin, the bisphenol A-type epoxy resin, the tricresyl phosphate, the polysiloxane, the talcum powder, and the mica powder, to obtain a mixture A; adding the zinc oxide crystal whisker, a dispersing agent, and a coupling agent into the mixture A, uniformly mixing, to obtain a mixture B; and adding a defoaming agent and a flatting agent into the mixture B, after uniformly dispersing in a high speed, to obtain the wear-resistant anti-static paint. The provided wear-resistant anti-static paint has a stable and good anti-static property and good corrosion resistance, and is suitable for various electronic devices, chemical industry devices, energy devices, and anti-static sites, such as an electronic appliance factory, a fuel factory and an automobile refueling station.

Description

technical field [0001] The invention relates to the field of paint preparation, in particular to a wear-resistant and antistatic paint and a preparation method thereof. Background technique [0002] Antistatic coatings are functional coatings that have the ability to conduct electricity and dispel accumulated static charges. Antistatic coatings have been developed along with modern science and technology, and have a history of more than half a century. As early as 1948, the United States published a patent for making conductive adhesive from silver and epoxy resin, which was the earliest disclosed conductive paint. In the 1950s, Japan began to produce anti-static coatings mainly based on silver and carbon. In the 1960s, the United States, Britain, Japan and other countries successively developed antistatic coatings. In the 1980s, foreign antistatic technology and electrothermal coating technology developed rapidly, and my country also began to study and apply antistatic c...
