Abstract

The invention discloses a high-resistance nickel-chromium electrothermal alloy material for electric heating elements. The alloy material comprises a nickel-chromium alloy main body, wherein the nickel-chromium 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 hydroxide, 3.3 parts (by weight) of amino trimethylene phosphonic acid, 2.1 parts (by weight) of gamma-epoxy propyl ether trimethoxysilane and 1.1 parts (by weight) of nonylphenol ethyl oxide carboxylate into 40 parts (by weight) of deionized water, and carrying out uniform stirring; (2) then, sequentially adding 5.5 parts (by weight) of diethylene glycol phenyl ether, 2.6 parts (by weight) of methyl vinyl ketone, 0.5 part (by weight) of secondary sodium alkyl sulfate and 0.7 part (by weight) of benzotriazole e 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 nickel-chromium alloy main body in the film coating treatment solution, taking out the nickel-chromium alloy main body, and then, baking the nickel-chromium alloy main body. According to the high-resistance nickel-chromium electrothermal alloy material for the electric heating elements, disclosed by the invention, the surface of the nickel-chromium alloy main body is coated with a protective film, so that the performance is good, and the surface smoothness is good.
