Problems solved by technology

[0003] The existing metal flash paint, the paint liquid itself can conduct electricity, but the resistivity of this paint liquid itself is unstable, and it is used for electrostatic automatic spraying, and the paint film is very easy to be "broken down", which makes the paint film on the workpiece spray Uneven, and more seriously, this has the potential to trip the production line and cause a fire
[0004] At the same time, during electrostatic spraying construction, the paint film formed at one time is thicker, and the metallic glitter paint is easy to bloom, and the spraying decoration effect is poor

preparation example Construction

[0016] The preparation method of acrylic resin metal flash baking varnish of the present invention is as follows:

[0017] 1) Disperse the aluminum-silver paste: weigh the aluminum-silver paste in the dispersion tank, accurately weigh the organic solvent in another bucket, stir well to make a mixed solvent, and add the mixed solvent to the dispersion tank containing the aluminum-silver paste, Use a high-speed disperser to disperse for 20-40 minutes at a speed of 1-8m / s, and set aside;

[0018] 2) Add the metal pigment alignment aid into the organic solvent, stir, dissolve, and set aside;

[0019] 3) Paint preparation: Weigh and put acrylic resin and amino resin in order in the paint mixing tank, turn on the high-speed disperser and adjust the speed to 1-8m / s, and add metal pigment alignment aids, leveling agents, For the remaining materials such as conductive additives, after adding each material, disperse for 20-60 minutes.

[0020] 4) Paint preparation: Add the aluminum-si...

Abstract

The invention discloses acrylic resin metallic brilliant baking paint. The baking paint comprises the following components in parts by mass, 25 to 55 parts of acrylic resin, 10 to 35 parts of amido resin, 4 to 20 parts of aluminum paste, 5 to 25 parts of metal pigment alignment auxiliary agent, 0.2 to 2.0 parts of flatting agent, 0.1 to 2.0 parts of conductivity improver, and 5 to 25 parts of organic solvent. When the acrylic resin metallic brilliant baking paint is used for an auto spray coating line, punch-through cannot occur in a range that construction voltage is between 50 and 120kV in a working solution state of low impedance (1 to 10 M omega), and the acrylic resin metallic brilliant baking paint has the advantages of high varnishing rate of paint liquid, uniform and flat paint film appearance and excellent paint film performance, and can meet the requirement on paint film performance of most home appliance, ironware and artware.

Description

technical field [0001] The invention relates to a metallic flash paint, in particular to an acrylic metallic flash paint which can be used in an electrostatic automatic production line. Background technique [0002] The spraying efficiency of electrostatic automatic line is high, the rate of paint application is high, and the loss of paint is more than 30% lower than that of conventional methods. Therefore, electrostatic automatic spraying is more and more used in various batch coatings. [0003] The existing metal flash paint, the paint liquid itself can conduct electricity, but the resistivity of this paint liquid itself is unstable, and it is used for electrostatic automatic spraying, and the paint film is very easy to be "broken down", which makes the paint film on the workpiece spray Uneven, and more seriously, this has the potential to trip the production line and cause a fire. [0004] At the same time, during the construction of electrostatic spraying, the paint fil...
