Conductive heating coating

Abstract

The invention relates to the technical field of a chemical coating, specifically to a conductive heating coating. The coating comprises the following materials, by weight, 40-80 parts of graphite powder, 30-50 parts of acetone, 5-20 parts of zinc dust, 1-5 parts of silicon dioxide and 1-5 parts of silicone oil. The invention aims to provide an efficient and high temperature resistant conductive heating coating.

Description

Technical field [0001] The invention relates to the technical field of chemical coatings, in particular to a conductive heating coating. Background technique [0002] Since the 1960s, the United States, Britain, Japan and other countries have begun to develop conductive coatings, using polyethylene, polystyrene varnish or sodium silicate as a binder, adding carbon black, graphite powder and metal powder to make conductive coatings. It is called electric heating paint, but the heating temperature is generally not more than 100 ℃, otherwise the film layer is easy to arc and burn when power is applied. The current prior art has the disadvantages that the conductive material of the electric heating paint is easy to oxidize, and the film layer is easy to be burned by arcing, so the heating temperature rise is limited. Summary of the invention [0003] The purpose of the present invention is to provide an efficient and high temperature resistant conductive heating paint. [0004] The te...
