preparation example Construction

[0044] A method for preparing finished paints of various colors for vehicle appearance repair, characterized in that it comprises the following steps:

[0045] S1. Weigh each required coating by a certain weight portion;

[0046] S2. Slowly add various components into the container tank, and disperse at a speed of 500r / min or less for 20-30min with a disperser to obtain a mixed solution;

[0047] S3. Take 20 grams of evenly dispersed mixed solution, and observe the color difference between the color and the model from 30°, 45°, and 90° angles with a paint ruler. If the color difference is large, you can add appropriate color paint to adjust the color difference. When fine-tuning, use a disperser to disperse and fine-tune;

[0048] S4. Take 20 grams of the mixed liquid that is evenly dispersed and the color is closest to the sample, spray the sample with a size of 10×10cm with a spray gun, and dry the sample in an oven. Car boards are compared, when the color difference is te...

Embodiment 1

[0052] S1, a kind of proportioning of gray finished paint with black as the main bluish phase (also known as fixed color paint, original factory paint) for repairing the appearance of a vehicle, including the following coatings by weight: 50 parts of high molecular weight acrylic black paint , 20 parts of high-molecular acrylic white paint, 5 parts of high-molecular acrylic blue paint, 5 parts of high-molecular acrylic red paint, 5 parts of high-molecular acrylic yellow paint, 5 parts of high-molecular acrylic resin, and 10 parts of solvent. In this example, the polymeric acrylic paint can be oily or water-based. When the polymeric acrylic paint is a paint, the polymeric acrylic resin must be oily, and the solvent must be an organic solvent.

[0053] Specifically, in this implementation example, the carbon black used in the polymer acrylic black paint is Orion 6# high-pigment carbon black.

[0054] Specifically, in this implementation example, the titanium dioxide used in the ...

Embodiment 2

[0064] S1. A kind of gray finished paint with black as the main reddish-yellow phase for vehicle exterior repair. The proportioning ratio: 37 parts of high-molecular acrylic black paint, 20 parts of high-molecular acrylic white paint, 15 parts of high-molecular acrylic red paint, high-molecular acrylic paint 5 parts of yellow paint, 3 parts of polymer acrylic green paint, 10 parts of polymer acrylic resin, and 10 parts of solvent.

[0065] Specifically, in this implementation example, the carbon black used in the polymer acrylic black paint is Orion FW200 high-pigment carbon black.

[0066] Specifically, in this implementation example, the titanium dioxide used in the polymer acrylic white paint is rutile titanium dioxide by filtration method.

[0067] Specifically, in this implementation example, the pigment used in the polymer acrylic green paint is phthalocyanine green pigment.

[0068] Specifically, in this implementation example, the pigment used in the polymer acrylic r...

Abstract

The invention discloses a preparation method of various-color finished paint for vehicle appearance repair. The preparation method comprises the following steps of: firstly, weighing required paint according to certain weight parts; then acquiring a mixed solution, lifting a paint mixing ruler, respectively observing the color difference between the color and a sample plate from angles of 30 degrees, 45 degrees and 90 degrees, and finely adjusting the color difference; then spraying a sample plate by using a spray gun, drying the sample plate by using an oven, comparing the dried sample platewith an original vehicle plate, and determining that the color is qualified when the color difference is less than 0.5 by using a colorimeter; and finally, adjusting the viscosity by using the mixed solution with qualified test color to obtain the qualified finished paint. The method can be used for preparing the repairing finished paint with the color very close to that of the original vehicle body, the appearance colors are consistent during vehicle repairing, the construction efficiency is improved, the universality and the practicability of the paint are improved, the colors can meet the repairing requirements of various vehicle body colors of various vehicles on the market through preparation of the various-color finished paint for vehicle appearance repair, and the paint can be widely applied to vehicle coatings.

Description

technical field [0001] The invention relates to the technical field of preparation of polymer coatings for vehicles, in particular to a finished paint of various colors for vehicle exterior repair, also known as color-fixing paint and original factory paint, hereinafter referred to as "finished paint" Background technique [0002] As early as December 3, 2015, our company was authorized for the invention patent of "a vehicle paint", the patent number is "ZL201310218567.1". Through this patented technology, butyl methacrylate, butyl acetate, 2-hydroxyethyl methacrylate, isobutyl acrylate, isobutyl methacrylate, styrene, six-membered ring carbonate lactone, Silica powder or talcum powder or aluminum silicate powder, pigments, etc. are used as vehicle paints as the main raw materials, and sprayed with a spray gun, a coating with bright color and smooth paint layer can be obtained on the vehicle body. [0003] Vehicle paint can not only protect the vehicle sheet metal from corr...
