Description

technical field [0001] The invention relates to the technical field of water-based paint, in particular to a flame-retardant water-based paint and a preparation method thereof. Background technique [0002] Water-based paint is a type of paint that uses polymer emulsion as a film-forming substance. It is usually made of synthetic resin as the base material, and then supplemented with pigments, fillers and various additives. Because of its good decorative effect, convenient construction, little environmental pollution and low cost, it is widely used in indoor walls, Decorative decoration of the ceiling. [0003] Water-based paint is a paint that uses water as a dispersion medium and thinner. Compared with organic solvent-based paints, water-based paint not only reduces the emission of volatile organic solvents, but also saves resources and energy (energy consumption is required to produce solvents), and is convenient. Transport and storage. According to the dispersion form...
