Anti-scraping and anti-wear color coated steel plate

Abstract

The invention discloses an anti-scraping and anti-wear color coated steel plate, which comprises a base plate, wherein the base plate comprises a low-carbon steel plate, a hot galvanized layer and analloy anti-wear layer; the alloy anti-wear layer is laminated on the lower surface of the low-carbon steel plate; the hot galvanized layer is laminated on the lower surface of the alloy anti-wear layer; an anti-scraping and anti-wear layer is laminated on the upper surface of the low-carbon steel plate; the top end of the anti-scraping and anti-wear layer is coated with a finishing coat layer; a protective layer is arranged on the outer surface of the finishing coat layer; a chemical reaction layer is arranged on the lower surface of the hot galvanized layer; and the lower end of the chemicalreaction layer is coated with a primer layer. The anti-scraping and anti-wear color coated steel plate is high in wear resistance and high in anti-scraping strength; the anti-scraping and anti-wear layer is made of polyvinylidene fluoride; quartz powder is added and used as a reinforce; and therefore, the wear resistance of the polyvinylidene fluoride is improved, and the strength is enhanced.

Description

technical field [0001] The invention relates to the technical field of decorative material processing, in particular to a scratch-resistant and wear-resistant colored coated steel plate. Background technique [0002] With the development of the economy and the improvement of living standards, the application fields of color-coated steel plates continue to expand. At present, high-grade color-coated steel plates have been increasingly used in building materials industries such as high-clean workshops, cold storage, three-dimensional garages, etc., and are also used in Some electrical appliances such as set-top boxes, some home appliance panels such as the back and side panels of refrigerators and freezers, solar water heaters, etc., as well as ship decoration, interior decoration and furniture industries. It is required to have excellent scratch resistance and wear resistance, excellent long-term use performance and beautiful outer tube. [0003] After more than 20 years of ...

AI Technical Summary

Problems solved by technology

[0003] After more than 20 years of development history, the color-coated steel plate industry has been greatly developed in my country, and its output has grown at an average rate of 40% per year. However, the existing color-coated steel plates have poor scratch and wear resistance. , when the steel plate is made into a finished product, it is often damaged, which seriously affects the quality of the product and has poor practical performance
