Abstract

The invention discloses a method for applying a polyether-ether-ketone heat-conducting insulating coating. The method for applying a polyaryletherketone film comprises the steps of directly coating prepared polyether-ether-ketone h heat-conducting insulating coating which is uncooled on base material, cleaning the coated base material with water, removing solvent and inorganic salt, drying in a baking oven for 3-5 hours at the temperature of 180 DEG C, and then placing the material into a vacuum sintering furnace and sintering for 5-10 minutes at the temperature of 380-400 DEG C to obtain thebase material of which the surface is coated with polyether-ether-ketone. The polyether-ether-ketone heat-conducting insulating coating is obtained by adding a heat-conducting inorganic filler in thesynthetic process of polyether-ether-ketone. The coating has good thermal conductivity, insulativity and toughness and can be widely applied to a non-sticky cookware and chemical anticorrosion. By adopting the application method, the traditional construction process is simplified, and PEEK (polyether-ether-ketone) coating material with smooth surface and excellent toughness and durability can be more easily obtained.

Description

technical field [0001] The invention relates to the field of high-performance special engineering plastics, in particular to a method for using polyetheretherketone heat-conducting and insulating coatings. Background technique [0002] PEEK coatings are widely used in the field of high temperature resistant and anti-corrosion materials. Coatings made of PEEK are used in various fields around the world: cooking utensils, such as soldering irons and frying pans; water pump parts; gaskets on the top of automobile cylinders; compressor parts; semiconductor wafer holders; oil field antennas; food and chemicals mixing parts. [0003] PEEK coatings have huge advantages such as superior abrasion resistance, durability and adhesion. Compared with fluorine coatings and nylon coatings, PEEK coatings mainly show the following advantages: 1. There is no need to pre-coat the transition layer, which simplifies the construction process. 2. The solvent can be recycled after construction, ...
