Problems solved by technology

[0002] At present, most of my country's automobile manufacturing industry is using solvent-based automotive paints, and the organic solvents in solvent-based automotive paints contain a large number of substances harmful to the human body and the environment. During the production and automotive spraying process, a large amount of organic solvents will volatilize. Cause air pollution and safety hazards, causing harm to personnel and the ecological environment
To solve this problem, it is necessary to solve the problem of organic solvents in automotive paints. This is also a problem that has been solved and overcome in the field of coatings for many years. Water-soluble automotive paints have been developed for primers, intermediate paints, and metallic paints. Only the paint for the last process—water-based base paint or varnish has not been overcome, resulting in the environmental protection problems of automobile production and spraying.

Embodiment Construction

[0014] Water-based automotive paint is divided into: finish varnish, organic pigment color paint (black, blue, green, red) and inorganic pigment color paint (white, yellow, iron red, orange red).

[0015] (1) Finish varnish (paint):

[0016]

[0017] The above materials are put into the tank under the stirring of the disperser, fully stirred for 20 minutes to make them uniform, and the physical and chemical indicators are tested. After passing the test, they are packaged in separate tanks, which is the finished product.

[0018] (2), organic pigment paste (black, blue, green, red)

[0019]

[0020] Put the deionized water into the tank, the speed of the disperser is 500-1000 rpm, and put in the wetting agent, ammonium salt dispersant, copolymer dispersant, defoamer, pigment in turn, after stirring for 20-30 minutes, pass through the sand mill Grind to below 15μm, then add bactericide and stir for 10 minutes.

[0021] (3), inorganic pigment paste (white, yellow, iron re...

Abstract

The invention discloses a high-gloss water-based paint for car. The finishing varnish is prepared by mixing methacrylate resin(27-36%), ethyl acrylate resin(31-41%), water-soluble methyl-etherifying amino resin(9-14%), water-soluble polyurethane rheological agent(0.1-0.3%) , water-based polyurethane thickening rheology agent(3-5%) and deionized water(3-18.5%) in a container. A colored paint can be made by adding pigment concentrates into the finishing varnish. The stabilities of pigment dispersing into tiny particles and the miscibility of different pigments are guaranteed by using blended dispersants to wet and disperse the pigment. Good film fullness and glossiness can be obtained due to a higher solid content of the water-based paint by a mixture of more than two high-solid basic resin. The specification of this paint reaches and surpasses the standard level of common solvent car varnish by reducing the pollution of the harmful volatile organic solvent.

Description

1. Technical field [0001] The invention belongs to the technical field of paint production, and in particular relates to a production method of a finishing varnish and a color paint used in the last process of an automobile spraying process. 2. Background technology [0002] At present, most of my country's automobile manufacturing industry is using solvent-based automotive paints, and the organic solvents in solvent-based automotive paints contain a large number of substances harmful to the human body and the environment. During the production and automotive spraying process, a large amount of organic solvents will volatilize. Air pollution and potential safety hazards are caused, causing harm to personnel and the ecological environment. To solve this problem, it is necessary to solve the problem of organic solvents in automotive paints. This is also a problem that has been solved and overcome in the field of coatings for many years. Water-soluble automotive paints have bee...
