Abstract

The invention discloses a polytetrafluoroethylene coating and a preparation method thereof. The polytetrafluoroethylene coating comprises the following components: polytetrafluoroethylene, epoxy resin, organic silicon resin, silver powder, benzyldimethyl ketal, ammonium stearate, 2-((2-hexyloxy)ethoxy)ethanol, calcium dodecylbenzene sulfonate, ammonia water, aluminum oxide, copper powder, graphite powder, diacetone alcohol, tributyl phosphate, dimethyldiallylammonium chloride and epoxy chloropropane. The preparation method comprises the following steps of adding polytetrafluoroethylene, epoxy resin, organic silicon resin, the silver powder, ammonium stearate, the copper powder, the graphite powder, aluminum oxide, tributyl phosphate and 2-((2-hexyloxy)ethoxy)ethanol into a reaction kettle, heating and uniformly stirring; then, discharging after grinding by using a grinder to obtain a mixture I; stirring and uniformly mixing the rest components, and grinding to form a mixture II with the particle size same as that of the mixture I; and finally, mixing the mixture I and the mixture II.

Description

technical field [0001] The invention relates to a paint, in particular to a polytetrafluoroethylene paint and a preparation method thereof, and belongs to the technical field of chemical paint preparation. Background technique [0002] The R & D technology of new functional materials is one of the factors to measure the development level of a country's productivity. It can affect the development of many fields such as electronics, aerospace, communications, etc. Conductive materials are one of them. Conductive coatings refer to coatings on non-conductive substrates. On the surface, it is a functional coating with a certain ability to conduct electric current and dissipate static charge. Due to its special functions, conductive coatings can be used to eliminate static electricity, electromagnetic shielding, electric heating and anti-corrosion, and have been widely used in various fields such as modern electronics, construction, transportation and military affairs. Compared w...
