Problems solved by technology
The general colors of automotive electrophoretic paint produced by domestic paint manufacturers are gray and black, which are used as anti-corrosion primers. If you want to change the color, under normal circumstances, you need to discard and update the matching tank, and you have to bear environmental risks and cost losses. Risk and cost of bath liquid treatment, etc.

Embodiment 1
[0035] An online toning electrophoretic paint, comprising the following components, in parts by weight (parts)
[0058]The anti-corrosion pigment can be selected from AF-700, AF-710 or strontium chromate. The filler is kaolin ASP170, kaolin ASP200 or superfine talcum powder. The anti-sedimentation pigment adopts expanded EW or white carbon black PDS-1 dispersant, SV5040 or SN5050. The neutralizing agent adopts monoethanolamine and triethylamine. Co-solvent adopts propylene glycol methyl ether, propylene glycol butyl ether or butanol. The yellow pigment adopts Bayer Iron Yellow, Lead TH629 or Lead TH630, and the red pigment adopts Bayer Iron Red, Lead TH671 or Lead TH672. Titanium dioxide adopts R930, R2190, CR828 or...

Abstract
The invention relates to on-line color-mixing electrophoresis paint, which is characterized in that the paint comprises following components with parts by weight of 50-70 parts of water-base resin, 1-3 anti-rot pigment, 6-9 titanium dioxide, 1-3 yellow pigment, 2-4 red pigment, 3-6 filling, 0.5-1 anti-immersion pigment, 0.2-0.6 dispersing agent, 1-3 neutralizing agent, 8-15 deionized water and 6-10 auxiliary solvent. The beneficial effect of the invention is that on-line color-mixing electrophoresis has the characteristics of voltage resistance, salt fog resistance and easy dispersion, can beprepared into complex pigment, and has excellent paint film property and favorable stability. The paint has excellent of pigment wetting dispersing function, can be used to research on-line color-mixing color master-batch paint through optimizing pigment, anti-immersion agent and auxiliary agent and the like, achieves the technical requirements of on-line color-mixing paint, monitors the generation of tank liquor of electrophoresis paint production flow in different time through utilizing the beam splitting and color measurement technology and gas chromatography technology, the change of paint film and color difference delta E, and realizes the on-line color-mixing.
Description
technical field [0001] The invention belongs to chemical industry and paint, and in particular relates to an on-line toning electrophoretic paint mainly used in the fields of automobiles, industrial anticorrosion and daily household appliances and a preparation method thereof. Background technique [0002] Anodic electrophoretic coating is a new type of anti-corrosion coating with water as solvent. It does not pollute the environment, is non-toxic and harmless, saves organic solvents, has no fire hazard, and has excellent corrosion resistance and high throwing power. It can be used for any complicated workpieces. It has the advantages of uniform and dense coating, high degree of coating automation, and low environmental pollution. At present, anodic electrophoretic coatings are mainly divided into epoxy ester type, phenolic type, polybutadiene type, and acrylic type. The first three types are dry oil esterified synthetic resins, and are added with unsaturated carboxylic acid...
