Abstract

The invention discloses an ultralow-VOC water-based metal glaze and a preparation method thereof. The ultralow-VOC water-based metal glaze comprises the following components, in percentages by weight:30%-46% of a water-based acrylic resin dispersion, 8%-10% of amino resin, 40%-55% of purified water, 0.2%-0.8% of a wetting levelling agent, 0.5%-0.8% of a dispersing agent, 0.1%-0.4% of an anti-sagging auxiliary agent, 0.1%-0.3% of a defoaming agent, 0.8%-1.5% of an adhesion promoting agent, and 0.2-2% of DMEA; and the preparation method of the ultralow-VOC water-based metal glaze comprises thefollowing steps: putting the water-based acrylic resin dispersion, the DMEA, and the purified water into a container, and performing uniform stirring; adding the amino resin, the wetting levelling agent, the dispersing agent, the defoaming agent, the anti-sagging auxiliary agent and the adhesion promoting agent, performing uniform mixing, performing dispersion at a high speed for 30-60 min, and performing adjustment by using the purified water to a desired viscosity with to obtain glaze slurry; and performing filtration on the glaze slurry, and performing packaging to obtain the ultralow-VOC water-based metal glaze product. The metal glaze provided by the invention solves the problem that a current metal glaze contains a large amount of VOCs.

Description

technical field [0001] The invention relates to the field of water-based industrial paints, in particular to an ultra-low VOCS water-based metallic glaze and a preparation method thereof. Background technique [0002] Metallic glaze is a special artistic glaze in the ceramic industry glaze. It is mainly applied on antique bricks and tiles, and also on bottles, vases or art porcelain for daily use. The surface of the ceramic tile with metallic glaze presents a metallic luster, and can present various colors, such as red, yellow, silver, blue, black and so on. [0003] Metallic glaze can emit metallic luster, has a special formula, and is widely used in the market at present; It is easy to cause acute poisoning. In mild cases, headache, dizziness, cough, nausea, vomiting, or drunkenness may occur; in severe cases, liver poisoning or even coma will occur soon, and some may be life-threatening. Long-term living indoors polluted by volatile organic compounds can cause chronic p...
