Abstract

The invention discloses modified wear-resistance paint for casts. The paint is prepared from the following components in parts by weight: 20-27 parts of dual-component polyurethane, 15-22 parts of modified graphene, 6-8 parts of mica powder, 2-3 parts of a silane coupling agent KH-570, 5-7 parts of sodium orthophosphate, 8-19 parts of an alkyd resin, 5-9 parts of aluminum silicate, 25-35 parts of acrylic modified polyurethane, and 15-26 parts of a glycerine epoxy resin. The invention provides the modified wear-resistance paint for the casts, and the outside paint films of the casts, using the paint, not only have high abrasion resistance, but also have high corrosion resistance.

Description

technical field [0001] The present invention relates to coatings and, in particular, to a modified wear-resistant coating for castings. Background technique [0002] Paint is a chemical mixture paint that can firmly cover the surface of objects for protection, decoration, marking and other special purposes. [0003] Coatings belong to organic chemical polymer materials, and the formed coating film belongs to the type of polymer compounds. According to the classification of modern chemical products, coatings belong to fine chemical products. Modern coatings are gradually becoming a class of multifunctional engineering materials and an important industry in the chemical industry. The external coating film of existing castings often falls off due to wear and tear, resulting in poor appearance or affecting use. Contents of the invention [0004] The purpose of the present invention is to provide a modified wear-resistant coating for castings, so as to solve the problem in t...
