Problems solved by technology

In addition, in order to achieve a certain high flicker effect, several aluminum powders and pearls are often combined, which is complicated in formula design, long in production cycle, and poor in product stability.
During the construction of the automobile factory, the color, appearance and performance of the paint film are greatly affected by the formula of the paint itself, resulting in poor workability
[0004] The defects in the prior art are: improving the scintillation of colored paint can only be carried out by increasing the particle size and adding ratio of aluminum powder and pearl powder in the formula; one is that the range of raw materials to be selected is narrow; The aluminum powder and pearl powder made of aluminum powder have poor workability, and the paint film is prone to defects such as zebra patterns and ghost images in practical applications. In addition, it is easy to separate the filtrate and block the filter bag when filtering in the production and on-site circulation pipelines, and the potential risk is very high. ; The third is to add a high proportion of pigments and fillers to make the appearance and performance of the paint film worse, resulting in hidden dangers in appearance and performance

Abstract

The invention discloses solvent-based colored paint with a high flickering degree effect. The solvent-based colored paint is prepared from the following components in parts by weight: 4 to 16 parts offirst amino resin, 23 to 37 parts of first acrylic resin, 0.01 to 10 parts of pigment filler, 3 to 6 parts of microgel, 1 to 4 parts of a first anti-settling agent, 0.02 to 1.2 parts of a first stabilizer, 0.01 to 1 part of an auxiliary, 0.01 to 1 part of a dispersant, 0.1 to 5 parts of a resistance regulation auxiliary, 12 to 25 parts of semi-finished resin and 6 to 52 parts of a first solvent.According to the solvent-based colored paint with the high flickering degree effect, glass powder serving as the pigment filler is added into coating, and can be suitable for both solvent-based coating and water-based coating, so that a paint film with high flickering effect is finally obtained. The coating prepared with the preparation method is high in performance, high in storage stability, high in product quality stability and low in cost, and is suitable for low, middle and high-grade vehicle models in the market.

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to a solvent-based color paint with high scintillation effect and a preparation method thereof. Background technique [0002] With the soaring of the automobile market, consumers have higher and higher requirements for automobile colors. At the same time, automobile manufacturers are constantly developing new colors to improve the flashing effect of current market colors, and the requirements for coatings are also getting higher and higher. , Such as: the previous plain paint gradually transitioned to metallic paint, pearlescent metallic paint, etc. Traditional solvent-based coatings can give better brightness, saturation and better sparkle to the paint film, but with the stringent environmental protection requirements and regulations, the application range of solvent-based coatings is getting narrower and the requirements are getting higher and higher , and water-based coatings hav...
