Abstract

The invention discloses a high-resistance chromium-nickel electrothermal alloy material for electric heating elements. The alloy material comprises a chromium-nickel alloy main body, wherein the chromium-nickel alloy main body is subjected to film coating treatment; the film coating treatment comprises the following steps: (1) sequentially adding 1-2 parts (by weight) of sodium silicate, 1.1 parts (by weight) of hydrolytic polymaleic anhydride, 2.8 parts (by weight) of polyethylene glycol and 0.7 part (by weight) of sodium alkylarylsulfonate into 40 parts (by weight) of deionized water, and carrying out uniform stirring; (2) then, sequentially adding 5.9 parts (by weight) of methyl laurate, 3.1 parts (by weight) of methacrylic acid, 1.3 parts (by weight) of sodium alpha-cyclohexylsulfamate and 0.8 part (by weight) of N-phenyl-2-naphthylamine into the solution, and continuing to carry out stirring until thorough and uniform mixing is achieved, so as to prepare a film coating treatment solution; (3) dipping the chromium-nickel alloy main body in the film coating treatment solution, taking out the chromium-nickel alloy main body, and then, baking the chromium-nickel alloy main body. According to the high-resistance chromium-nickel electrothermal alloy material for the electric heating elements, disclosed by the invention, the surface of the chromium-nickel alloy main body is coated with a protective film, so that the performance is good, and the surface smoothness is good.
