Description

A kind of water-based paint and preparation method thereof

【Technical field】

The invention relates to decoration materials used in the construction field, in particular to a water-based paint and a preparation method thereof.

【Background technique】

Water-based paint is a paint that uses water as a medium and diluted. Compared with organic solvent paint, water-based paint not only reduces the emission of organic solvents (VOC) but also saves organic material resources, thereby greatly reducing the impact of organic solvent volatilization on the atmosphere in the paint. Pollution and fire hazards during construction. Water is an extremely abundant resource on the earth. It is easy to use and low in cost. It is used as a solvent in paint and will not cause damage to water resources or less. Therefore, water-based coatings not only reduce the emission of volatile organic solvents, but also save resources and energy, and are convenient for transportation and storage. With the enhancement of people's awareness of environmental protection, the relevant environmental protection laws and regulations on the production and use of chemical products are becoming more and more stringent, making water-based coatings have become the mainstream direction of the development of modern coatings industry.

Most of the water-based paints currently used in the market use water-based synthetic acrylic resin emulsion as the base material, titanium dioxide as the pigment, and calcium carbonate as the main filler. This kind of paint has poor color retention and relatively single color. Defects.
