Problems solved by technology
In the late 1970s, the appearance requirements of automobile topcoats became higher and higher. Especially in recent years, the vividness of the coating has been taken as the main reference index of automobile topcoats, and the requirements for clarity, wear resistance and flatness are also Great improvement, especially the increase in coating brightness, greatly increases the technical difficulty of automotive topcoats
The automotive topcoat has strong adhesion, acid and alkali resistance, oxidation resistance and other chemical resistance properties, and has excellent properties such as anti-wear and scratch resistance, but its solvents are toxic solvents such as xylene and butanol, and are volatile Strong, harmful to the environment and human body

Abstract
The invention discloses environment-friendly nano-metal automobile finish. The automobile finish is prepared from the following components in parts by weight: 30-50 parts of waterborne acrylic resin, 25-40 parts of amino resin, 2-6 parts of nano-metal powdered slurry, 1-3 parts of pearl powder, 1-2 parts of rectorite nano-powder, 5-10 parts of dimethyl silicone oil, 3-8 parts of sodium hydroxymethylglycinate, 1-2.5 parts of alkylphenol ethoxylates, 0.5-1 part of a crosslinking agent, 0.08-0.15 part of surfactant and 20-30 parts of deionized water. The nano-metal automobile finish has the advantages of high coating hardness, good scraping resistance, good corrosion resistance, excellent abrasion resistance, low VOC content, no toxicity and environmental friendliness.
Description
Technical field: [0001] The invention relates to the technical field of automobile coating, in particular to an environment-friendly nano-metal automobile topcoat. Background technique: [0002] From the perspective of development, automotive paints include early oil paints, later nitro paints, phenolic paints, alkyd paints, and water-based paints, synthetic resin primers, aminoacrylic paints, metallic flash paints, electrophoretic paints and paints in recent decades. Powder coating etc. [0003] Before the 1950s, the top coats for automobiles were mainly room temperature self-drying alkyd paints, nitro spray paints and volatile acrylic resins. After the 1950s, automotive topcoats were gradually replaced by thermosetting amino baking varnishes. In the 1970s, amino baking varnishes in automotive topcoats had dominated. In the late 1970s, the appearance requirements of automobile topcoats became higher and higher. Especially in recent years, the vividness of the coating has ...
