Abstract

The preparation method comprises the following steps: adding water, a dispersing agent and a defoaming agent into a stirring tank, stirring, then adding a flame-retardant additive, continuously stirring to obtain a mixture A, adding montmorillonite particles and hollow glass beads into the mixture A, stirring for 1-2 hours to obtain a mixture B, adding the mixture B into the stirring tank, and stirring for 1-2 hours to obtain the water-based paint capable of forming the large-particle bumps. The pure acrylic emulsion, the coalescing agent, the wetting agent and the flatting agent are added into the mixed material B and stirred, the thickening agent is added to adjust the viscosity, and the water-based paint is obtained. According to the water-based paint, large-particle protruding points can be formed on the surface of a matrix through montmorillonite particles and hollow glass beads, the protruding points are full and firm and are not prone to falling off, the large-particle protruding points can adsorb harmful gas, and therefore the water-based paint is environmentally friendly. And by adding the flame-retardant additive, the water-based paint is endowed with excellent flame-retardant and fireproof performance.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based coating capable of forming large particle bumps and a preparation method thereof. Background technique [0002] Coatings are a mixture of polymer substances and ingredients, and can be coated on the surface of the substrate to form a new type of polymer material that firmly adheres to a continuous coating film. Any coating that uses water as a solvent or as a dispersion medium can be called water-based coatings. The biggest difference between water-based coatings and solvent-based coatings is that most of the organic solvents in the coatings are replaced by water, which is composed of water, organic matter, fillers, etc. Water-based coatings are the development trend of the architectural decoration industry. They have the following characteristics: use water as a solvent, save resources, reduce the risk of fire during construction, and reduce air pollution; Good adaptabilit...
