Phase separation self cleaning acrylate stone-like paint emulsion and preparation method thereof

Abstract

The invention discloses phase separation self cleaning acrylate stone-like paint emulsion and a preparation method thereof, and belongs to the field of stone-like paint emulsion. The phase separationself cleaning acrylate stone-like paint emulsion is prepared from the following raw materials in parts by weight: 160 to 240 parts of deionized water, 30 to 60 parts of styrene, 30 to 80 parts of methyl methacrylate, 40 to 80 parts of butyl methacrylate, 40 to 80 parts of acrylic acid-2-ethylhexyl acrylate, 10 to 40 parts of functional monomers, 4 to 25 parts of emulsifying agents, 2 to 20 parts of initiators and 1 to 10 parts of pH regulators. The self cleaning acrylate stone-like paint emulsion provided by the invention has the advantages that a copolymerization and shell-core technology composite process is used; a special synthesis processing method is used; special latex particles with two phases in one emulsion are finally obtained; latex particles in the film forming process are mutually interlinked and wound; the formed film is compact and hydrophobic; the pollution particle dwell can be effectively prevented.

Description

technical field [0001] The invention relates to an acrylic ester emulsion, in particular to a phase-separated self-cleaning acrylic real stone paint emulsion and a preparation method thereof, belonging to the field of real stone paint emulsions. Background technique [0002] Real stone paint is a kind of coating product mainly made of high-performance polymer emulsion, natural or artificially dyed colored sand of various colors, and various additives. Real stone paint has the following characteristics: environmental protection and durability, fire prevention, waterproof, acid and alkali resistance, pollution resistance, non-toxic, tasteless, strong adhesion, etc., can effectively prevent the external harsh environment from eroding buildings, and is suitable for use in most areas ; The cost is low, equivalent to about a quarter of dry-hanging marble; the construction process is simple, and the color and pattern can be selected according to personal preferences to achieve pers...

Problems solved by technology

At present, due to the increasingly fierce competition in the real stone paint market, in order to compete with their peers and increase profits, many real stone paint manufacturers and constructors do not carry out surface treatment after the real stone paint is constructed. It will soon become gray, and the color is obviously different from that at the beginning of construction, and the coating is not easy to clean, which affects people's perception of the appearance of the building
