Embodiment 1

[0034] A special coating for water-based home appliance plastics, consisting of the following raw materials in parts by weight:

[0035] 35 parts of water-based modified acrylic emulsion resin, 25 parts of water-based modified polyurethane emulsion resin, 16 parts of water-based modified epoxy resin, 1 part of defoamer, 1 part of dispersant, 1.5 parts of anti-settling agent, 0.5 parts of bactericide, organic 9 parts of color pigments, 11 parts of deionized water;

[0036] The preparation method is:

[0037] Mix the above raw materials according to the stated ratio, stir and disperse, then grind to obtain a fineness below 20 μm, then add the deionized water to adjust the viscosity to reach the 4# cup for 35-45 seconds, filter and pack to obtain "Product A ".

Embodiment 2

[0039] 55 parts of water-based modified acrylic emulsion resin, 15 parts of water-based modified polyurethane emulsion resin, 11 parts of water-based modified epoxy resin, 1.5 parts of defoamer, 1 part of dispersant, 1 part of anti-settling agent, 0.5 part of bactericide, organic 9 parts of color pigments, 6 parts of deionized water;

[0040] Its preparation method is identical with embodiment 1, the product "B" of gained.

Embodiment 3

Abstract

The invention discloses a water-based household appliance plastic special coating and a preparation method of the coating, and belongs to the technical field of coatings. The water-based household appliance plastic special coating comprises the following raw material components by mass: 45-80% of combined resin, 8-15% of deionized water, 7-15% of a pigment, and 0-10% of an auxiliary agent; wherein the combined resin is prepared from water-based modified acrylic emulsion resin, water-based modified polyurethane emulsion and water-based modified epoxy resin; and the auxiliary agent is prepared from a defoaming agent, a dispersing agent, an anti-settling agent and a sterilizing agent. According to the coating disclosed by the invention, the adhesion effect is good, and requirement for the surface of a base material is low; the film-forming time is short, and the construction efficiency is high; the solid content is high, the viscosity is low, and construction is facilitated; the freezing resistance is high, freezing is avoided, and the coating can be used at -10 DEG C; alcohol resistance and washing resistance are high, and cleaning of household appliance parts is facilitated; and the weather-resistant, damp-heat-resistant and temperature-change-resistant effects are good, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a special coating for water-based home appliance plastics and a preparation method thereof. Background technique [0002] With the continuous development of the domestic economy and the improvement of people's living standards, people pay more and more attention to environmental protection and other aspects. Consumers not only require more complete, newer and more convenient functions for household appliances, but also have high expectations for the environmental protection and appearance quality of home appliances. And decoration also put forward higher requirements. Painting, as the most important surface treatment method for the appearance of home appliances, will be supervised and condemned for behaviors and industries that endanger and destroy the living environment. [0003] Most of the coatings used in the home appliance industry, especially the coating on plastic parts,...
