Waterborne color transparent glass paint and preparation method thereof

Abstract

The invention discloses a waterborne color transparent glass paint and a preparation method thereof and relates to the glass paint industrial field. The waterborne color transparent glass paint comprises the following raw materials by weight percent: 60%-68% of waterborne epoxy emulsion, 4%-8% of waterborne amino resin, 2%-4% of cosolvent, 0.3%-0.8% of neutralizer, 15%-20% of deionized water, 5%-10% of waterborne metal complex dye, 0.5%-1.0% of waterborne silane coupling agent and 0.1%-0.4% of waterborne defoaming agent. After the waterborne color transparent glass paint prepared by the preparation method is sprayed on the surface of glass, the glass is roasted at 180-200 DEG C for 10-15min for curing and film-forming; and the paint film has bright color, high glossiness, good transparency, good water boiling resistance, high hardness and high adhesive force to glass.

Description

technical field [0001] The invention relates to the field of glass coating industry, in particular to a water-based colored transparent glass paint and a preparation method thereof, which are mainly used for coating protection and decoration of glass and glass products. Background technique [0002] As a functional and environment-friendly water-based paint, water-based glass paint, especially water-based colored transparent glass paint, has the advantages of obvious decorative effect, gorgeous paint film color, and easy cleaning. It is widely used in glass lamps, wine glasses, vases, lanterns, candlesticks, etc. decorative items. [0003] However, due to the weak permeability of the solvent (water), the poor wettability of the water-based paint to glass, and the high surface finish of the substrate (glass), it is difficult for the water-based paint to adhere well to the glass substrate. Seriously hindered the development of water-based glass paint. At present, the types o...

Problems solved by technology

[0003] However, due to the weak permeability of the solvent (water), the poor wettability of the water-based paint to glass, and the high surface finish of the substrate (glass), it is difficult for the water-based paint to adhere well to the glass substrate. Seriously hindered the development of water-based glass paint

At present, the types of water-based glass paint mainly include polyurethane aqueous dispersion type, water-soluble polyacrylic resin type, acrylate modified polyurethane type, etc. The main problems are poor adhesion, poor chemical resistance, poor solvent resistance, and poor boiling resistance.
