Embodiment 1

[0016] The water-based colored transparent glass varnish provided by the present embodiment 1 is made by following raw materials proportioning by weight, specifically:

[0017] 61% water-based epoxy emulsion, 7.5% water-based amino resin, 3.5% co-solvent, 0.6% neutralizer, 19% deionized water, 7.6% water-based metal complex dye (Yellow-099), 0.6% Water-based silane coupling agent and 0.2% water-based defoamer.

[0018] Among them, Shanghai Lujia G-935 can be used for water-based epoxy emulsion, and INEOS R-747 resin can be used for water-based amino resin;

[0019] The preparation method of above-mentioned water-based colored transparent glass paint specifically comprises the following steps:

[0020] 1) Add water-based epoxy emulsion, water-based amino resin, co-solvent, neutralizer and deionized water into the stock preparation pot in sequence according to the above raw material ratio, and stir for 5-10 minutes;

[0021] 2), add the water-based metal complex dye into the m...

Embodiment 2

[0025] The water-based colored transparent glass varnish provided by the present embodiment 2 is made by following raw materials proportioning by weight, specifically:

[0026] 65% water-based epoxy emulsion, 6% water-based amino resin, 3% co-solvent, 0.5% neutralizer, 17% deionized water, 7.4% water-based metal complex dye (Red-311), 0.8 % of water-based silane coupling agent and 0.3% of water-based defoamer.

[0027] Its preparation method is the same as that of Example 1, and will not be repeated here.

[0028] The method adopted in this embodiment, wherein, the hydroxyl group and ether bond contained in the molecular structure of the water-based epoxy resin, after curing reaction with the amino resin, further generate new hydroxyl group and ether bond, so that the paint film has very high cohesion and adhesion Adhesion; at the same time, the thermal expansion coefficient of epoxy resin is small, which makes the adhesion of the paint film good; when preparing, the water-ba...

Embodiment 3

[0030] The water-based colored transparent glass varnish provided by the present embodiment 3 is made by following raw materials proportioning by weight, specifically:

[0031] 67% water-based epoxy emulsion, 5% water-based amino resin, 2.5% co-solvent, 0.4% neutralizer, 16% deionized water, 7.8% water-based metal complex dye (Blue-762), 0.9 % of water-based silane coupling agent and 0.4% of water-based defoamer.

[0032] Its preparation method is the same as that of Example 1, and will not be repeated here.

[0033] The method adopted in this embodiment, wherein, the hydroxyl group and ether bond contained in the molecular structure of the water-based epoxy resin, after curing reaction with the amino resin, further generate new hydroxyl group and ether bond, so that the paint film has very high cohesion and adhesion Adhesion; at the same time, the thermal expansion coefficient of epoxy resin is small, which makes the adhesion of the paint film good; when preparing, the water...

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...
