Problems solved by technology

[0002] Several electrothermal paint patents (publication numbers CN1068582, CN1112592) have been disclosed on the market at present. They mainly use carbon powder and graphite as fillers. The problem that exists is that the resistance of these electrothermal paints is all above tens of ohms. If the filler content is used to reduce the resistance, the adhesion of the coating will become poor, and the heating efficiency will be relatively low in actual use, which is not conducive to practical application

Description

technical field [0001] The invention relates to the field of coatings, mainly a carbon crystal coating. Background technique [0002] Several electrothermal paint patents (publication numbers CN1068582, CN1112592) have been disclosed on the market at present. They mainly use carbon powder and graphite as fillers. The problem is that the resistance of these electrothermal paints is all above tens of ohms. If the filler content is used to reduce the resistance, the adhesion of the coating will become poor, and the heating efficiency will be relatively low in actual use, which is not conducive to practical application. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a carbon crystal coating, which can be used for indoor and outdoor heating coatings for integrated ceilings and integrated walls. It can realize heating and heating, and through the control of resistivity, it can meet different ...
