Description

A pure latex paint

technical field

The invention mainly relates to the field of coatings, in particular to an odor-clean latex paint.

Background technique

A large class of synthetic resin emulsion coatings represented by acrylate copolymer emulsions. Latex paint is a water-dispersible paint. It is based on synthetic resin emulsion, and the filler is refined by adding various additives after grinding and dispersing. Latex paint has many advantages that are different from traditional wall paints, such as easy to paint, fast drying, water-resistant paint film, good scrub resistance, etc.; water-soluble interior wall latex paint is non-polluting, non-toxic, and has no fire hazards. Brush and dry quickly, the paint film has good water resistance and scrub resistance, and the color is soft. Water-soluble interior wall latex paint, using water as the dispersion medium, has no environmental pollution problems caused by organic solvent poisonous gases, has good air permeability, and avoids the disadvantages of blistering of the coating film caused by the temperature and pressure difference between the inside and outside of the coating film. Dry new wall paint.
