Wear-resistant paint applied to surface coating of metal bolt piece

Abstract

The invention discloses a wear-resistant coating applied to a surface coating of a metal bolt piece. The wear-resistant coating is prepared from the following components in parts by weight: 30 to 40 parts of methyl etherified high imino melamine resin emulsion, 30 to 40 parts of acrylic resin emulsion, 2.5 to 3 parts of hydrochloric acid solution, 20 to 23 parts of sodium chloride, 1.7 to 2 parts of stannous chloride, 0.6 to 1.3 parts of hydroquinone, 8 to 16 parts of water, 0.5 to 1 part of flatting agent, 0.4 to 0.6 part of modified polydimethylsiloxane and 8 to 12 parts of coalescing agent. Methyl etherified high-imino melamine resin emulsion and acrylic resin emulsion are used as reaction matrixes and matched with components such as a hydrochloric acid solution, sodium chloride, stannous chloride and hydroquinone, and a film layer which is good in dispersity and excellent in adhesive capacity can be formed through curing under promotion of a coalescing agent; and the formed film layer has the characteristic of good salt spray corrosion resistance.

Description

technical field [0001] The invention belongs to the technical field of surface coatings, in particular to a wear-resistant coating applied to the surface coating of metal bolts. Background technique [0002] A screw is a tool that uses the circular rotation and friction of an object's inclined plane to tighten the device's parts step by step. Screws are indispensable industrial necessities in daily life, such as cameras, glasses, clocks, electronics and other products. Screws, commonly used screws for TV, electrical products, musical instruments, furniture, etc., as well as large screws used in engineering, construction, and bridges, have different materials or shapes according to different application places, among which metal screws with a protective layer on the surface are the most Commonly, the surface coating of this type of metal screw is usually an oily surface coating or an anti-oxidation metal coating. Among them, the surface coating formed by the paint is usually ...

[0002] A screw is a tool that uses the circular rotation and friction of an object's inclined plane to tighten the device's parts step by step. Screws are indispensable industrial necessities in daily life, such as cameras, glasses, clocks, electronics and other products. Screws, commonly used screws for TV, electrical products, musical instruments, furniture, etc., as well as large screws used in engineering, construction, and bridges, have different materials or shapes according to different application places, among which metal screws with a protective layer on the surface are the most Commonly, the surface coating of this type of metal screw is usually an oily surface coating or an anti-oxidation metal coating. Among them, the surface coating formed by the paint is usually more likely to be damaged, because the surface varnish coating used is poor, and it is difficult to adhere to the coating. On the surface, and the formed paint layer is not smooth enough, it is easy to be damaged when the bolt is used
