Waterborne interference type pearly flashing paint for automobile and preparation method of waterborne interference type pearly flashing paint

Abstract

The invention discloses a waterborne interference type pearly flashing paint for an automobile and a preparation method of the waterborne interference type pearly flashing paint. The waterborne interference type pearly flashing paint is prepared from the following components: mica pearl powder dispersion paste, waterborne polyurethane dispersoid, self-thickening acrylic emulsion, waterborne amidogen resin, a thickening agent, an amine neutralizer, a diluent and water. The waterborne interference type pearly flashing paint has scientific matching, the components are adjusted mutually, the drying speed is high, the construction performance is good, the requirements of 2C1B coating process on coating are met, costs are greatly saved, energy consumption is reduced, and the water-soluble interference type pearly flashing paint has the advantages of energy conservation and emission reduction. A paint film formed by the pearly flashing paint has gorgeous and gentle gloss, has pearly colors, is full of sense of beauty, does not have phenomena such as color difference, floating, seediness, dulling or poor pearl effect, has excellent water resistance and corrosion resistance performance andgood weather resistance performance, and meets the decorative requirements of limousines.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a water-based interference type pearlescent glitter paint for automobiles and a preparation method thereof. Background technique [0002] The development of modern automotive coatings not only actively changes to green environmental protection, but also strives to give cars a good aesthetic feeling. The color of the car body has gradually become a symbol to show the personality of the car owner. People have higher and higher requirements for the high decorativeness of the car top paint. of favor. According to statistics, at present, more than 70% of the color paints of cars at home and abroad are made of metallic color or pearlescent color or the mixed color of the above two pigments, and the demand for the latter two is increasing. [0003] Pearlescent paint has a gorgeous and soft luster and illusion-like colors, and has always been a commonly used color paint fo...

AI Technical Summary

Problems solved by technology

For example: the flash-off time between the varnish and the pearlescent paint is insufficient or the solvent is not compatible, that is, the pearlescent paint does not achieve a sufficient interval time, and "insufficient drying" causes part of the pearlescent pigment to be dissolved by the varnish, and the result is that the pearlescent pigment in the pearlescent paint Or other pigment particles float to change the position, causing color difference and blooming (cloud spots); the viscosity of the paint is not adjusted properly, the greater the amount of diluent, the lower the viscosity of the base paint, the easier it is to produce floating color and fading. Flowers and other paint film disadvantages, resulting in color difference; pearlescent pigments have complex surface properties, uneven dispersion in the paint, resulting in flocculation, precipitation, granulation, and poor pearlescent effects; the weather resistance and corrosion resistance of resin base materials are not enough or The selected pearlescent pigment is not suitable, which will easily cause the paint film to lose its luster
