Problems solved by technology

The metal flash paint used on automobiles is mostly solvent-based metal flash paint. The coating process is to bake the electrophoretic primer, and then spray the metal base paint and finish varnish system. The investment in large production equipment is large, and the process Complex, high production costs, high requirements for technical personnel, and pollution to the environment; at the same time, this coating method is difficult to apply to hardware, small household appliances, handicraft industries, so automobiles, hardware, small household appliances, handicrafts, etc. The industry is calling for new environmentally friendly, low-cost, high-quality metallic flash paint

Embodiment 1

[0042] Referring to Figure 1, add 100g of aluminum silver powder into a reaction kettle equipped with 1000g of cationic acrylic resin, then add 20g of dispersant and 40g of thickener in sequence, control the stirring speed at 150 rpm, and control the temperature at 20°C for 3 hours. After the aluminum silver powder is fully wrapped by the resin, add 2000g of deionized water to emulsify, then add 80g of color paste to make a flash electrophoretic paint solution, and after aging for 2 hours, the present invention is obtained, and the flash electrophoretic paint can be obtained by carrying out electrophoretic construction of the present invention membrane.

Embodiment 2

[0044] Add 60g of pearlescent powder into a reaction kettle equipped with 1000g of cationic polyurethane resin, then add 10g of dispersant and 30g of thickener in turn, control the stirring speed at 1500 rpm, and control the temperature at 50°C for 0.5 hours, and the pearlescent powder passes through the resin After fully wrapping, add 2000g of deionized water for emulsification, then add 50g of color paste to make a flash electrophoretic paint solution, and after aging for 2 hours, the present invention is obtained, and the flash electrophoretic paint film can be obtained by carrying out electrophoretic construction of the present invention.

Embodiment 3

[0046] Add 100g of aluminum silver powder and 100g of pearl powder into a reaction kettle equipped with 1000g of cationic acrylic resin and 500g of cationic epoxy resin, then add 50g of dispersant and 40g of thickener in turn, control the stirring speed at 150 rpm, and control the temperature Stir at 25°C for 3 hours, after aluminum silver powder and pearl powder are fully wrapped by resin, add 4000g of deionized water for emulsification, then add 300g of color paste to make flash electrophoretic paint solution, and the present invention can be obtained after aging for 2 hours. The flash electrophoretic paint film can be obtained by electrophoretic construction.

Abstract

The present invention discloses one kind of flash electrophoretic paint and its preparation process. The flash electrophoretic paint is compounded with the materials including resin as the base material 1000-1500 weight portions, flash powder 15-200 weight portions, dispersant 5-50 weight portions, thickener 5-100 weight portions, color paste 50-300 weight portions and deionized water 2000-4000 weight portions. The electrophoretic paint film formed with the flash electrophoretic paint and through an electrophoresis process has high toughness, high hardness, bright beautiful color, no discoloring and excellent corrosion resistance. The electrophoretic paint may be used to replace available paint combination of electrophoretic primer, color primer and coating varnish, and this results in short technological path and low cost. In addition, the water-thinned electrophoretic paint is environment friendly.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a flash electrophoretic paint and a preparation method thereof. Background technique [0002] With the development of society and the advancement of science and technology, the field of coatings and coatings has ushered in an era of diversification, multi-variety, multi-function and colorfulness. The metal flash paint used on automobiles is mostly solvent-based metal flash paint. The coating process is to bake the electrophoretic primer, and then spray the metal base paint and finish varnish system. The investment in large production equipment is large, and the process Complex, high production costs, high requirements for technical personnel, and pollution to the environment; at the same time, this coating method is difficult to apply to hardware, small household appliances, handicraft industries, so automobiles, hardware, small household appliances, handicrafts, etc....
