Abstract

The invention discloses an electro thermal paint and preparation thereof, which relates to the technical field of chemical coating. The raw material of the electro thermal paint comprises, by weight, 4-30 parts of polyurethane resin, 3-5 parts of cellulose acetate resin, 8-10 parts of epoxy resin butyl acetate, 8-10 parts of acrylic resin, 8-10 parts of inorganic nano ceramic and mixture of the diluents of butyl acetate, dim ethyl benzene and cyclohexanone in a ratio of 30:45:25. The electro thermal paint is prepared from the mixture of the mixture prepared , elastic polyurethane emulsion, compound zinc phosphate, waterborne silicone acryl ate emulsion, anhydrous wolfram, barium sulfate, m-nitro phenol, calgon, p-chlorophenol, ammonium polyphosphate, silane coupling agent and solvent at the certain ratio by stirring evenly and grinding in a ball crusher. Compared to the existing technology, the electro thermal paint and preparation thereof has the advantages of high heating efficiency and good adhesion.

Description

technical field [0001] The invention belongs to the technical field of chemical coatings, in particular to a synthesized electrothermal coating and a preparation method thereof. Background technique [0002] The electrothermal coating has the function of heating after the safety voltage is connected to two levels. By controlling the resistivity of the coating, different heating requirements can be met, and the performance of 5°C to 20°C higher than the ambient temperature can be achieved. . At present, such coatings on the market basically use carbon powder and graphite as conductive fillers. The coatings made of such fillers have a large resistance value, even reaching tens of ohms or more. If you want to further increase the content of conductive fillers to achieve If the resistance value is reduced, the adhesion of the coating will be deteriorated, and in actual use, there will be relatively low heating efficiency, higher than the safe voltage of 36 volts, and poor safet...
