Abstract

The invention discloses a household appliance color plate textured finish paint coating and a preparation method thereof, and belongs to the field of color-coated steel plate coatings. The coating comprises the following components in parts by weight: 55-60 parts of saturated polyester resin; 10 to 15 parts of amino resin; 0.5 to 1 part of a defoaming auxiliary agent; 0.5 to 1 part of an acid catalyst; 0.4 to 0.8 part of polysiloxane; 0.3 to 0.5 part of fumed silica; 5 to 10 parts of aluminum powder; 8-10 parts of a solvent; and 5-10 parts of color paste. The household appliance color plate textured finish paint coating can form different surface texture effects by being matched with primers of different colors, the textured effect of a coating after film forming is uniform, no short lineis generated, and the construction mode and application performance of roller coating can be met. In addition, a paint film formed by the household appliance color plate textured finish paint coatingis high in hardness, high in scratch resistance and easy to process, and has wide application prospects.

Description

technical field [0001] The present application relates to the field of color-coated steel plate coatings, in particular to a skin-grain finish coating for home appliance color-coated steel plates and a preparation method thereof.
