Abstract

The invention discloses an anti-scratch aqueous automobile nano coating and belongs to the technical field of automobile coatings. The automobile nano coating includes the following raw materials, by weight, 30-50 parts of alkyd resin, 20-30 parts of light calcium carbonate, 10-20 parts of ethylene glycol amine, 10-20 parts of span-80, 0.5-3 parts of chitosan, 5-10 parts of nano zinc oxide, 5-10 parts of nano zirconium dioxide, 0.1-1 part of nano sheet-like brass powder, 1-10 parts of branch-like polyamide, 0.5-2 parts of polycarboxylate, 0.1-1 part of a defoamer and 20-40 parts of water. The alkyd resin is prepared by polymerizing soybean oleic acid and glycerin. The aqueous nano coating has the advantages of both aqueous coatings and nano coatings, is environment-friendly in performance, is simple in preparation, is convenient to use, is less in thickness of a coating layer, can save raw materials, is odor-free in a coating film, is strong in anti-washing performance, is excellent in toughness, is 0-grade in adhesion force and 4H in thickness, is high in coating fullness and is widely used in automobile coating.

Description

technical field [0001] The invention belongs to the technical field of automotive coatings, in particular to a scratch-resistant water-based automotive nano coating. Background technique [0002] Automobile coatings refer to the coatings applied on the body and parts of various vehicles such as cars, and generally refer to coatings and auxiliary materials for new cars and coatings for vehicle repairs. With the development of my country's automobile industry, the growth of automobile ownership has provided a huge market development space for my country's automobile coating industry. [0003] Existing automobile paints are prone to paint surface cracking and falling off; at the same time, due to the increasing number of vehicles, scratches between automobiles are unavoidable; the existing automobile paints have poor scratch resistance and cannot satisfy people. Demand for Automotive Coatings. Contents of the invention [0004] The invention provides a scratch-resistant wat...
