Embodiment 1

[0030] According to the preparation process of the above-mentioned formula water-based industrial dip coating:

[0031] Dispersion: Add water-based alkyd-modified acrylic resin, deionized water, neutralizer, wetting and dispersing agent, defoamer, drier, high-pigment carbon black, anti-rust pigment, and filler to the mixing tank in sequence according to the formula Medium, rotating speed 800r / min, disperse for 15min;

[0032] Grinding: Grind the dispersed slurry on a sand mill, and check the fineness every 15 minutes until the slurry fineness is ≤30 μm;

[0033] Thinning: put the slurry with qualified grinding fineness into the paint mixing container, and adjust to the required viscosity to obtain the water-based industrial dip coating.

Embodiment 2

[0035] According to the preparation process of the above-mentioned formula water-based industrial dip coating:

[0036] Dispersion: Add water-based alkyd-modified acrylic resin, deionized water, neutralizer, drier, defoamer, wetting and dispersing agent, high-pigment carbon black, antirust pigment, and filler to the mixing tank in sequence according to the formula Medium, rotating speed 800r / min, disperse for 15min;

[0037] Grinding: Grind the dispersed slurry on a sand mill, and check the fineness every 15 minutes until the slurry fineness is ≤30 μm;

[0038] Thinning: put the slurry with qualified grinding fineness into the paint mixing container, and adjust to the required viscosity to obtain the water-based industrial dip coating.

[0039] The above-mentioned Example 1 can be ground for 1.5 hours to reach the specified fineness of 30 μm, and Example 2 can be ground for 2 hours to reach the specified fineness of 30 μm.

Abstract

The invention discloses a preparation process of a water-based industrial dip-coating paint, comprising the following steps of: dispersion: sequentially adding water-soluble resin, deionized water, afunctional assistant, high-pigment carbon black, an antirust pigment and a filler into a stirring tank according to the formula ratio, and dispersing at the rotating speed of 800 r / min for 15min; grinding: grinding the dispersed slurry on a sand mill, and detecting the fineness once every 15 minutes until the fineness of the slurry is less than or equal to 30 microns; and diluting: putting the slurry with qualified grinding fineness into a paint mixing container, and adjusting to the required viscosity to obtain the water-based industrial dip-coating paint. The process can improve the paint making efficiency.

Description

technical field [0001] The invention relates to a preparation process of water-based industrial dip-coating paint, and at the same time, the invention also relates to a water-based industrial dip-coating paint suitable for the preparation process. Background technique [0002] The surface of metal materials is easily damaged and rusted due to the oxidation of air during use, so it needs to be protected by anti-corrosion coating to make it unaffected before and after application. There are many ways of anti-corrosion coating, the common ones are spray coating, brush coating, roller coating, dip coating, shower coating and so on. The construction method of dip coating has been widely used in many fields because of its simple application process, high coating production efficiency, high paint utilization rate, low labor intensity and continuous production. In the field of motor vehicles, due to their small size, various types and complex structures, accessories, as special-sha...
