Car refinishing paint in blue-phase ultra-black color and preparation method thereof

Abstract

The invention relates to a car refinishing paint in a blue-phase ultra-black color and a preparation method thereof. The black paint comprises the following components in parts by weight: 18-26 parts of acrylic resin, 43-53 parts of cellulose acetate butyrate, 4-8 parts of dispersing auxiliary, 0.1-0.5 part of anti-settling agent, 9-13 parts of soaking solvent, 2.5-4.1 parts of pigment, 5-7.8 parts of solvent, 0.1-1 part of flatting agent and 0.1-1 part of UV auxiliary. According to the invention, a high pigment coating system carbon black pigment is adopted; the dispersing auxiliary with special dispersing effect for such a color, compared with the traditional dispersing auxiliary, has an obvious effect; the car refinishing paint can promote the tinting strength, blackness and blue-phase value; the pure black and black pearl color in high blackness can be conveniently and quickly regulated; and compared with the prior art, the car refinishing paint has the advantages of high saturation degree, pure color, sufficient blackness, obvious blue-phase feature and capability of meeting the market requirement for high-class car refinishing paint product.

Description

technical field [0001] The invention relates to an automobile refinish paint, in particular to a blue phase extra black automobile refinish paint and a preparation method thereof. Background technique [0002] According to the survey and statistics of the color and color development trend of automobiles every year, black occupies a large share, including plain black, black pearl, etc., and is one of the most popular colors for consumers. Whether it is the original whole car painting or partial repair, black is a main color masterbatch with a large amount. At present, black with red and yellow hue is the main color, and black with blue phase is supplemented. However, the occasions where special black with blue phase is used are increasing day by day. Many high-end models use more and more black with black phase. It has the characteristics of high density, heavy blue phase, clear and pure, without red and yellow phase, black appears turbid, it is easy to adjust from high blac...

Problems solved by technology

At present, black with red and yellow hue is the main color, and black with blue phase is supplemented. However, the occasions where special black with blue phase is used are increasing day by day. Many high-end models use more and more black with black phase. High density, heavy blue phase, clear and pure, no red and yellow phase, black appears turbid, easy to adjust from high blackness to low blackness, easy to adjust from blue phase to red and yellow phase, and vice versa

In order to achieve the characteristics of the blue phase, the existing manufacturers often use the method of mixing and grinding with blue pigments, but this method reduces the purity and blackness of the product, and cannot take into account both blackness and blue phase

[0003] Chinese patent CN 102146245 B discloses a blue-phase special black automotive refinish paint and its preparation method, which is made of the following raw materials in parts by weight: 74.29-78.29 parts of acrylic resin, 2.40-2.60 parts of high pigment carbon black powder, super dispersion aid 1.90-2.10 parts of agent, 0.95-1.05 parts of multiplier, 0.07-0.09 parts of high-pigment dye, 0.45-0.55 part of nano-titanium dioxide, and 16.63-18.63 parts of mixed solvent, but the high-pigment dye and nano-titanium dioxide added in the invention will affect the high-pigment dye and nano-titanium dioxide. The purity of pigment carbon black reduces the blackness and blue phase of the product, and the addition of dyes will affect the weather resistance and solvent resistance of the pigment system
