[0047]

[0048] The preparation of metal wheel paint in the present embodiment may further comprise the steps:

[0049] (1) Premixing: Add 2 parts of propylene glycol methyl ether acetate into the stirring tank for stirring; then slowly add 30 parts by weight of CR201-65, 1.3 parts of dispersant 32500, and stir at a speed of 700-800r / min (rev / min) 5-10min, adjust the premixed viscosity to 90-95KU / 25℃ with an appropriate amount of diluent;

[0050] (2) Soaking silver: Add 7.33 parts of butyl acetate into the stirring tank, then slowly add 8.5 parts of nano-metallic pigment 5000 and 1 part of nano-metallic pigment 706, stir evenly for 5-10 minutes (400 rpm), until uniform After soaking, add to the premix and stir well;

[0051] (3) Paint making: Add the remaining 22.7 parts of CR201-65, 20 parts of 821 amino resin, 1.4 parts of BYK-358N leveling agent, 3.3 parts of CAB 551-0.2, and 2 parts of S-100 solvent into the ...

Abstract

The invention belongs to the technical field of coatings, and particularly relates to one-step coated film-formed high-gloss automobile metal wheel hub paint and a preparation method thereof. The paincomprises 40-55 parts of acrylic resin, 20-26 parts of amino resin, 8.0-13 parts of nano-metal pigments, 4.0-7.0 parts of auxiliaries and 10-15 parts of diluents. The acrylic resin reacts with the butyl ether amino resin, and the one-step coated film-formed high-gloss automobile metal wheel hub paint with high-temperature resistance, good adhesive force and high additional values can be obtainedby the aid of the metal pigments. Moreover, an original triple-coating triple-baking or triple-coating one-baking preparation process is changed into a one-coating one-baking paint preparation process, and the paint has better performances such as high gloss and salt fog resistance. The method is simple in preparation process and suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a high-gloss automotive metal wheel hub paint formed into a film by one-time coating and a preparation method thereof. Background technique [0002] The automotive wheel industry has very strict quality requirements for coatings. To produce high-quality automobile wheels, high-quality materials, good coating technology and coatings with excellent comprehensive properties are required. At present, there is still a certain gap between domestically produced automobile wheel paint and foreign products in terms of quality and technology. Most of the traditional car wheel coating schemes are three coats and one bake, which is a complex process and high cost. [0003] Amino baking varnish mainly uses acrylic resin or alkyd resin and amino resin as the main film-forming substances. It is packaged in one component at room temperature, and at a higher temperature (about 130...
