Anti-incrustation heating pipe inner wall coating layer and machining process thereof

The invention provides an anti-incrustation heating pipe inner wall coating layer and a machining process thereof. The machining process comprises two steps of forming a bottom layer and a surface layer on the inner wall of a heating pipe through coating in sequence, wherein the bottom layer is obtained by coating bottom-layer paint; a preparation method of the bottom-layer paint comprises the following steps: firstly, chlorine-ether resins are fed in bottom-layer solvent for stirring and dissolving; then, polyether-ether-ketone powder and tetrafluoroethylene-hexafluoropropylene copolymer arefed; and a grinding machine is used for grinding; and a preparation method of the surface layer comprises the following steps: firstly, allyloxyethanol, Karstedt catalysts, ethoxylated trimethylolpropane triacrylate, the chlorine-ether resins and a first part of ultraviolet initiators are mixed as mixed liquid; then, the mixed liquid is dripped in hydrogen-contained silicone oil for reaction, andis cooled to the room temp
