Problems solved by technology

However, most of the current composite rock slab emulsions are simply compounded by elastic emulsion and ordinary emulsion. In the above compounded emulsion, due to the low glass transition temperature of the elastic emulsion, its water resistance and solvent resistance are extremely poor.
In addition, after the composite rock slice is mixed with the emulsion, it is very easy to break during storage and transportation, resulting in the pattern becoming smaller, discolored, and even gelatinized.
Therefore, traditional compound emulsions are difficult to meet the needs of composite rock slices.

Abstract

The invention discloses emulsion special for composite rock slices. The emulsion special for composite rock slices is characterized by comprising water, styrene, butyl acrylate, methyl methacrylate, methacrylamide, acrylic acid, a surface active agent and an initiator. The emulsion special for composite rock slices is prepared from, by mass, 50% of the water, 12%-17% of the styrene, 22%-27% of the butyl acrylate, 5%-10% of the methyl methacrylate, 2%-5% of the methacrylamide, 1%-4% of the acrylic acid, 1%-2% of the surface active agent and 0.1%-0.6% of the initiator. The emulsion special for composite rock slices has good water resistance and solvent resistance.

Description

technical field [0001] The invention relates to an architectural coating and a preparation method thereof, in particular to a special emulsion for composite rock slices and a preparation method thereof. Background technique [0002] Composite rock slices are architectural coatings that have been increasingly used in recent years. Since composite rock slices are mainly composed of inorganic materials and polymers, they not only have the advantages of complete color spectrum and rich colors, but also have strong weather resistance. The rock flake paint formulated with composite rock flakes has richer colors and more realistic imitation granite effects than traditional real stone paint, so it is widely favored by consumers. However, most of the current composite rock slab emulsions are simply compounded from elastic emulsions and ordinary emulsions. In the above compounded emulsions, due to the low glass transition temperature of the elastic emulsions, their water resistance ...
