Water-based decorative coating and preparation method thereof

Abstract

The invention discloses a water-based decorative coating and a preparation method thereof, and relates to the field of water-based coatings. The water-based decorative coating is prepared from the following parts by weight of raw materials: 25-50 parts of an aqueous hydroxyacrylic acid dispersion, 5-20 parts of a curing agent, 2-5 parts of a co-solvent, 1-5 parts of organic silicone powder, 0.1-3parts of menthol, 1-8 parts of a flame retardant, 0.05 to 0.5 part of nano zinc oxide, 0 to 10 parts of a pigment, 0.1 to 0.2 part of a pH adjuster, 0.1-0.2 part of a defoamer, 2 to 5 parts of a filmforming aid, 0.3 to 0.5 part of a dispersant, 0.3 to 0.5 part of a substrate wetting agent, 5 to 10 parts of deionized water and 0.5 to 1.0 part of a thickener. The water-based decorative coating hasa smooth paint film surface and strong stain resistance, has a certain antibacterial effect, achieves a fireproof effect, is suitable for appearance decoration and repair of plastic products such as flower arrangement, prolongs the use time of the plastic products, improves the production efficiency of the plastic products, and reduces production cost.

Description

technical field [0001] The invention relates to the field of water-based coatings, in particular to decorative and repairing coatings such as plastic flower arrangements. Background technique [0002] In daily life, plastic products such as flower arrangements are widely used as decorations, but plastic products will age and change color after long-term use, and are easy to burn. At the same time, using plastics of different colors will also reduce production efficiency and increase production costs. Processing can not only simplify the production process, but also obtain various appearance colors. As a low-VOC water-based environmental protection coating, it can achieve the application effect very well. [0003] VOC meaning: volatile organic compounds (volatile organic compounds); VOC is the English abbreviation of volatile organic compounds, and the chemical substances (except heavy metals) in wall paint that are usually harmful to human body refer to VOC. These volatile...
