preparation example Construction

[0045] It can be understood that the preparation method of the water-based metallic baking paint also has an important influence on the performance of the water-based metallic baking paint. In order to further make the overall system compatibility better, the present invention also provides a preparation method of water-based metal baking paint, please refer to figure 1 , the preparation method of water-based metal baking varnish comprises the steps:

[0046] S110: mixing and stirring the water-based acrylic resin and the amino resin to obtain a first mixture;

[0047] For example, the water-based acrylic resin and the amino resin are mixed at a speed of 450 rpm to 590 rpm and stirred for 6-10 minutes, so that the water-based acrylic resin and the amino resin are evenly mixed. Preferably, the water-based acrylic resin and the amino resin are mixed and stirred at a speed of 580 rpm for 7.5 minutes, so that the water-based acrylic resin and the amino resin are mixed more unifor...

Embodiment 1

[0068] Water-based metallic baking varnish comprises each component of following mass parts:

[0069]

[0070]

[0071] Its preparation method is as follows: water-based acrylic resin and amino resin are mixed and stirred at a rotating speed of 580rpm for 7.5 minutes to obtain the first mixture, after adding pigment and leveling agent to the first mixture, mixed and stirred at a rotating speed of 500rpm for 6 minutes , to obtain the second mixture; add neutralizing agent and cosolvent to the second mixture and mix and stir for 9 minutes at a rotating speed of 450rpm~590rpm to obtain a third mixture; add water to the third mixture at a rotating speed of 560rpm Mix and stir for 12 minutes to obtain the water-based metallic baking paint.

[0072] Its use method is as follows: add the water-based metallic baking varnish to a diluent to dilute to obtain a diluent, wherein the diluent is water; wherein the ratio of the water-based metallic baking varnish to the diluent is 1:0....

Embodiment 2

[0074] The difference with embodiment 1 is:

[0075] Water-based metallic baking varnish comprises each component of following mass parts:

[0076]

[0077] Other methods are the same as in Example 1.

Abstract

The invention relates to an aqueous metal baking varnish and a preparation method thereof, wherein the aqueous metal baking varnish comprises, by mass, 40-60 parts of an aqueous acrylic resin, 10-30 parts of an amino resin, 0.1-1.5 parts of a leveling agent, 1-10 parts of a neutralizing agent, 5-20 parts of a cosolvent, and 5-20 parts of water. According to the present invention, the film formingsubstance is formed by using 40-60 parts of the aqueous acrylic resin and 10-30 parts of the amino resin, and is subjected to the cross-linking reaction under the high temperature baking during the use so as to form the continuous phase on the metal surface, such that the decoration and protection effect is provided for the metal surface, the characteristics of high adhesion, high hardness, salt spray resistance, boiling resistance, wear resistance and the like can be achieved, the harm of the organic solvent to the construction operation is reduced, the aqueous metal baking varnish has good environmental protection property, the construction hazard is low, and the problems of traditional pinholes and blistering of the aqueous metal baking varnish can be solved.

Description

technical field [0001] The invention relates to the technical field of baking varnish, in particular to a water-based metal baking varnish and a preparation method thereof. Background technique [0002] With the development of home appliances and paint industry, the coating requirements of home appliances tend to be greener and more environmentally friendly, and the requirements for environmental protection are getting higher and higher. This puts forward higher requirements for the production and processing of coatings, and also makes the environmental protection quality and surface requirements of household appliances in the coating process and use process more and more high. [0003] In the traditional home appliance painting process, most of the paints used are solvent-based paints. The environmental protection of solvent-based coatings is poor, and the construction safety hazards are relatively large. During the spraying process of solvent-based paint, the solvent in ...
