Abstract

The invention relates to a glossy composition, a preparation method and a glossy method. The glossy composition comprises citric acid, hydroxyethylidene diphosphoric acid and dodecylbenzene sulfonic acid, and the mass ratio of the citric acid to the hydroxyethylidene diphosphoric acid to the dodecylbenzene sulfonic acid is (1-1.5): (2-4): (1-1.5). The method has the advantages that the metal oxide on the stainless steel fastener can be locally removed at a certain temperature by adopting the mild citric acid, and the influence on the size and the physical and chemical properties of the part is small; hydroxyethylidene-1, 1-diphosphonic acid is adopted as a weakly acidic complexing agent, oxides on the surface of the stainless steel fastener are adsorbed, complexed, loosened and separated from the surface through the complexing effect, and the effect of efficiently, rapidly and safely removing the oxides is achieved; dodecylbenzene sulfonic acid is used as an anionic surfactant and has the effects of reducing surface tension, increasing decontamination and cleaning capacity and improving the surface brightness of the stainless steel fastener.

Description

technical field [0001] The invention relates to the technical field of industrial manufacturing, in particular to a gloss composition, a preparation method and a gloss method. Background technique [0002] Stainless steel fasteners are processed by cold heading and warm heading, and then processed by rubbing and tapping processes. There will be a large amount of processing lubricating oil, high-temperature sludge and high-temperature metal oxides on the surface, and then undergo alkaline degreasing and degreasing processes, chemical Polishing and activation treatment can remove oil and sludge on the surface of stainless steel fasteners, between teeth, cross holes and inner holes, and can remove most of the colored oxides and metal oxide scales on stainless steel fasteners, but it needs to increase The bright appearance of fasteners must be processed with gloss. [0003] The existing products and processes of traditional stainless steel fasteners are as follows: [0004] 1....
