Water-based environment-friendly porcelain glaze-like plastic coating and preparation method thereof

Abstract

The invention discloses water-based environment-friendly porcelain glaze-like plastic coating and a preparation method thereof. The water-based environment-friendly porcelain glaze-like plastic coating adopts a formula comprising the following materials by mass: 20 to 40 percent of a water-based acrylic emulsion, 10 to 20 percent of water-based silica sol, 35 to 50 percent of water-based inorganic silicon dioxide nanodispersion, 0.1 to 0.3 percent of a wetting dispersant, 1 to 5 percent of silane, 0.1 to 0.5 percent of an amine neutralizing agent, 5 to 10 percent of lead-free pigment, 0.5 to 2.5 percent of a film-forming additive, and 5 to 25 percent of deionized water. The water-based environment-friendly porcelain glaze-like plastic coating can be coated on the surfaces of various materials in the form of porcelain glaze, and can be applied on the surfaces of the materials of various shapes through roller-applied coating, shower coating, spraying, blade coating, brush coating, dip coating and the like; moreover, the formed porcelain glaze coating is unique and free from hydrolysis, and cannot be melted at a certain temperature, so that a base material can be effectively protected from corrosion, abrasion, scraping, acid-alkali, impact, inflaming and fire.

Description

technical field [0001] The invention relates to the technical field of water-based imitation enamel materials, in particular to a water-based environment-friendly imitation enamel plastic coating and a preparation method thereof. Background technique [0002] With the development and progress of social civilization, people's awareness of low-carbon environmental protection is gradually increasing. Specifically, in terms of coating products, in addition to the requirements for the decorative function of coatings, they pay more attention to the needs of human health and environmental protection. At the same time, countries The enacted environmental regulations have strict restrictions on volatile organic compounds (VOC) in coatings. Controlling VOC emissions and pollution has become a worldwide environmental protection issue and an inevitable requirement for the development of circular economy in my country. Traditional solvent-based coatings contain a large amount of volatile ...

AI Technical Summary

Problems solved by technology

Traditional solvent-based coatings contain a large amount of volatile organic compounds (VOCs). VOCs are volatile organic compounds that have a huge impact on human health. At the same time, VOCs are also an important source of PM2.5, so they are also the main cause of smog. Inflammable and explosive, waste of petroleum resources, in addition, the traditional solvent-based coating film layer also has residual harmful substances pollution, pollution caused by the use of heavy metal pigments, etc.

[0003] In addition, the existing solvent-based coatings often have defects such as relatively poor fire resistance and flame retardancy, short service life, narrow application range, insufficient maintenance of material surface cleanness and aesthetics, complex preparation process, and high energy consumption.
