Epoxy ester dip-coating water based paint and preparation method thereof

Abstract

The invention discloses an epoxy ester dip-coating water based paint and a preparation method thereof, and belongs to the technical field of water based paints. The epoxy ester dip-coating water based paint is prepared by proportioning a base material, an auxiliary and a pigment filler according to weight percentage, wherein the base material is prepared from 30 to 35 percent of water based epoxy ester resin and 5 to 10 percent of a water based acrylic emulsion; the auxiliary is prepared from 3 to 6 percent of a cosolvent, 0.5 to 1 percent of a dryer, 1 to 2 percent of a neutralizer, 30 to 35 percent of deionized water, 0.5 to 2 percent of a wetting dispersant, 0.1 to 0.5 percent of a defoaming agent, 1 to 2 percent of a flash rust remover, 1 to 3 percent of a thickener and 1 to 3 percent of an anti-settling agent; the pigment filler is prepared from 8 to 12 percent of heavy metal-free black pigment and 5 to 10 percent of composite zinc phosphate. The water based paint is low in carbon content and environment-friendly; the problems of low storage stability, low salt fog resistance, low water resistance and low epoxy ester paint drying speed of the existing water based dip-coating paint can be solved; meanwhile, the shortcomings that the dip-coating paint is not liable to coat, cannot be hung at corners and has sagging and pilled-in selvedge are also overcome.

Description

technical field [0001] The invention belongs to the technical field of water-based paint, in particular to an epoxy ester dip-coating water paint and a preparation method thereof. Background technique [0002] At present, most engineering track coatings in my country use solvent-based spray paint or immersion paint. The disadvantages of the spray coating process are: large production area occupied, low production efficiency, and difficult to form balanced production; and low raw material utilization rate, large pollution, The labor intensity of the operator is high; in addition, due to the complex structure and shape of the track, there are many parts that are prone to leaking spray, which seriously affects the coating quality of the track. Using the dip coating method, although the utilization rate of the paint is high, the solvent-based dip-coating paint will release a large amount of VOC (volatile organic compounds) during the coating, causing air pollution, and the solven...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a kind of epoxy ester dip coating water paint and its preparation method. Oxygen ester paint has a slow drying speed problem, and at the same time solves the problems of dip paint that is not easy to apply thickness, no paint hanging on the corners, sagging, shrinkage, etc.
