Abstract

The invention discloses a high-resistance electric heating alloy wire for an electric heating element. The high-resistance electric heating alloy wire comprises a nickel-chromium alloy body, wherein the nickel-chromium alloy body is coated in the way of 1, adding 1-2 parts by weight of sodium sulfate, 0.7 part by weight of bis-imidazoline, 1.9 parts by weight of gamma-methacryloxy propyl trimethoxyl silane and 2.2 parts by weight of alkylethoxylate carboxylate to 40 parts by weight deionized water in sequence, and conducting uniform stirring; 2, adding 4.3 parts by weight of propylene glycol phenyl ether, 5.5 parts by weight of acrylonitrile, 1.6 parts by weight of sodium secondary alkyl sulfonate and 0.7 part by weight of 2-aminoethyl heptadecenyl imidazoline in sequence, and continuing stirring till sufficient and uniform mixing is achieved, so that coating treatment fluid is obtained; 3, placing the nickel-chromium alloy body in the coating treatment fluid to be soaked, and taking the nickel-chromium alloy body out to be dried. By coating the surface of the nickel-chromium alloy body with a protective film, performances are good, and surface smoothness is high.

Description

technical field [0001] The invention relates to a high-resistance electric heating alloy wire for electric heating elements. Background technique [0002] Existing high-resistance electric heating alloy wires for electric heating elements need to be improved in terms of abrasion resistance, oxidation resistance, corrosion resistance, rust resistance, and weather resistance of the nickel-chromium alloy main body, and the surface finish is not ideal. Contents of the invention [0003] The object of the present invention is to provide a high-resistance electric heating alloy wire for an electric heating element. The main body of the nickel-chromium alloy is coated with a film, and the surface of the main body of the nickel-chromium alloy is covered with a protective film, which has excellent abrasion resistance, oxidation resistance, corrosion resistance, Anti-rust, weather resistance, and good surface finish. [0004] In order to achieve the above object, the technical solu...
