Problems solved by technology

[0004] There are also many patents or documents in the prior art disclosing some water-based imitation stone paints and water-based enamel and their production methods, but the coating effects in these patents mostly only meet some basic physical performance indicators of environmental protection performance and paint film. The special additional functions are not very ideal, and the cost is high. In addition, most of these coatings do not have the characteristics of iron and wood general purpose and additional composite functions such as imitation stone illusion and anti-mold. Etc performance

Abstract

The invention discloses multifunctional waterborne enamel paint which comprises a first component, a second component and a fossil agent. The first component is mainly prepared from a water-soluble polyurethane dispersoid, a self-crosslinked phenylanine polymer, modified acrylic core-shell emulsion, modified epoxy silane, a film-forming agent, barium sulfate, functional additives, other additivesand water. The second component is mainly prepared from color concentrate and pigments. The fossil agent is mainly prepared from dipropylene glycol methyl ether acetate, ethyl alcohol and water. The multifunctional waterborne enamel paint forms high-weather-resistant stone imitation color intrigued coatings on metal substrates and wood substrates, surface decoration effects of the two substrates are enriched, firing energy consumption of ceramic stone imitation glaze can be reduced, natural stone extraction and secondary pollution are decreased, and the multifunctional waterborne enamel paintis environmentally friendly, low in carbon, efficient in energy, good in hardness, high in plumpness, resistant to stain and mold and medium in cost and can be universally used for the metal substrates and the wood substrates. The invention further discloses a preparation method of the multifunctional waterborne enamel paint.

Description

technical field [0001] The invention belongs to the technical field of water-based paints, and in particular relates to a multifunctional water-based enamel and a preparation method thereof, in particular to a general-purpose water-based imitation stone magic color enamel for iron and wood and a preparation method thereof. Background technique [0002] As a decorative material, enamel coatings have higher and higher decorative requirements and environmental performance. As enamel decorative materials, traditional solvent-based alkyd and PU enamel coatings have mature product formulas and processes. The performance can also meet the higher demand, mainly in good fullness, high hardness, good rust resistance and weather resistance, and not easy to tarnish, but because it contains a large amount of volatile organic compounds (VOC), it is harmful to air pollution and construction The health of personnel brings certain hazards, and the restrictions of relevant national environmen...
