Abstract

The invention discloses a nickel-chromium flat wire for electrical heating elements. The nickel-chromium flat wire comprises a nickel-chromium alloy body which is subjected to coating treatment, and coating treatment comprises the following steps that 1, 1-2 parts by weight of urotropine, 2.4 parts by weight of amino trimethylene phosphonic acid, 2.5 parts by weight of hexyldecanol and 0.7 part of lauryl trimethy ammonium chloride are put into 40 parts by weight of deionized water in sequence, and the materials are stirred to be uniform; 2, 5.6 parts by weight of polyvinyl alcohol, 8.5 parts by weight of ethyl acrylate, 1.3 parts by weight of igepon T and 0.7 part by weight of hexamethylenetetramine are added in sequence, stirring continues to be conducted till the materials are fully mixed to be uniform, and a coating treatment fluid is obtained; 3, the nickel-chromium alloy body is placed in the coating treatment fluid to be soaked and then taken out to be dried. According to the nickel-chromium flat wire for the electrical heating elements, the surface of the nickel-chromium is coated with a protective film, the performance is good, and the surface smoothness is good.

Description
