Micromolecular anionic waterborne glaze and preparation method thereof

Abstract

The invention relates to a micromolecular anionic waterborne glaze and a preparation method thereof. The micromolecular anionic waterborne glaze is prepared from 40%-50% of micromolecular waterborne acrylic emulsion, 5%-10% of micromolecular waterborne epoxy resin, 5%-8% of totally-methylated amino resin, 3%-5% of partly-methylated amino resin, 0.3%-0.5% of a defoaming agent, 0.2%-0.4% of a flatting agent, 0.3-0.8% of a wetting agent, 0.6%-1% of an anti-sagging aid, 0.6%-0.8% of an anti-doodling aid, 1%-1.5% of wax liquid, 3%-15% of anionic powder, 0.1-0.5% of a PH value regulator and the balance micromolecular water. As micromolecular water has high activity and small groups, air in a construction and spray site environment can be effectively purified; in the waterborne glaze spray process, the surface expansion force is small, and thus a surface glaze film is smoother; the micromolecular water in the glaze is regular in molecular structure arrangement and high in density, does not carry free charges, and can permeate into every part of a base material or parts with spray difficulty in the spray use process due to large seepage force and activation force; besides, sagging is not likely to occur, and the surface of the waterborne glaze is smoother and more saturated than that of glaze produced with deionized water or tap water on the market.

Description

technical field [0001] This invention relates to coatings. Background technique [0002] With the rapid development of my country's industry, the demand for surface treatment of high-end metal products such as magnesium alloy, aluminum alloy, magnesium-aluminum alloy, and stainless steel is increasing day by day, especially for automotive substrates, automotive wheels, and supporting products for high-end metals in the metal door industry. At present, the surface treatment materials used in the market are mainly oil-based paints. Oil-based paints are flammable and explosive, and have great safety hazards in production, transportation, and use. Moreover, the paints contain a large amount of organic substances such as benzene, ketones, and alcohol ethers. Solvents are harmful to the human body. Water-based glazes do not contain organic solvents such as benzene, ketones, and alcohol ethers. They use water as a solvent, bringing safety and environmental protection, and are becomi...

Problems solved by technology

However, the existing water-based glazes require high drying temperature, long surface drying time, and low permeability and wet spreadability, so there is a need for improvement
