Abstract
The invention discloses emulsion used for preparing real stone paint, texture paint and artificial granite composite coating finishing varnish. The emulsion consists of the formulas of 12-18 percent of butyl acrylate, 12-18 percent of methyl methacrylate, 0.2-0.5 percent of reactive emulsifying agent, 0.5-1 percent of water-soluble acrylic resin, 0.5-1 percent of acrylic amide, 0.5-1.5 percent of high-density cross-linking monomer and 0.2-0.5 percent of peroxysulphate. According to the emulsion, the water resistance and strength of the film can be improved, and the service life of the coating is prolonged. According to measurement, the prepared varnish has the effects that the coating is soaked in water, is not whitened within seven days and is not yellowed in the process of resisting ultraviolet rays for 1000 hours, and the coating glossiness is detected to reach 70 through an XGP 60-degree mirror glossiness meter.
Description
Technical field
The present invention relates to a kind of building coating emulsion, relate in particular to be used to the surface finishing varnish polymer emulsion of preparing true mineral varnish, texture paint, artificial granite composite coating.
Background technology
True mineral varnish, texture paint, artificial granite composite coating mainly adopt natural stone-powder and polymer emulsion mixed preparing to form.It is sprayed on skin, is the ideal architecture material that replaces lithotome.But true mineral varnish, texture paint, the bad shortcoming of artificial granite composite coating ubiquity water tolerance used now, coating becomes loose in each rain rear and the variable color of easily whitening.This causes because coating absorbs moisture, and major cause is to have used dispersion agent and emulsifying agent in the middle of the coating of preparation and emulsion.These not the emulsifying agent of polymerizable form the non-chemically emulsifying agent layer of bonding at coating surface, in case chance water makes moist and can cause the paint film water absorption and swelling, result not only affects architectural appearance, and greatly reduces the physicals that is sprayed on building surface coating, cause coating to peel off, affect coating work-ing life.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of and can improve paint film water tolerance and intensity, extend the coating finishing varnish emulsion in work-ing life.
The object of the present invention is achieved like this: this finishing varnish emulsion is a kind of acrylate polymer emulsion, and in this emulsion, each composition and mass percent thereof are:
Butyl acrylate 12%～18%
Methyl methacrylate 12%～18%
Reactive emulsifier 0.2%～0.6%
The water soluble acrylic resin 0.5%～1%
Acrylamide 0.5%～1%
High-density cross-linking monomer 0.5%～1.5%
Persulphate 0.2%～0.5%
Water 60%～70%.
Described reactive emulsifier is: the mixture of one or more in allyl group polythioether sodium sulfate, methacrylic hydroxide sodium dimercaptosulphanatein, allyl group polythioether sodium sulfosuccinate.
Described high-density cross-linking monomer is: the mixture of one or more in hydroxyethyl methylacrylate, methacryloxypropyl trimethoxy silane, vinyltrimethoxy silane, Rocryl 410, trimethylolpropane trimethacrylate.
Described persulphate is: the mixture of one or more in ammonium persulphate, Potassium Persulphate and Sodium Persulfate.
Above formula reacts by conventional emulsion polymerization can obtain this kind acrylate polymer emulsion.
The present invention compared with prior art has good weatherability, water-tolerant, glossiness is good, and can increase the work-ing life of coating, its reason have following some:
1, selective reaction type emulsifying agent improves the paint film water tolerance.Reactive emulsifier has obvious advantage than conventional emulsifier, it is synthetic in the middle of emulsion polymer with covalent linkage, avoid emulsifying agent resolve or move latex film from polymkeric substance, greatly reduced the hydrophilic radical of coating surface, thereby improved the water tolerance of paint film.
2, select the high-density cross-linking monomer, particularly selected polymerisable silane crosslinker, not only strengthen cross-linking density, and water resistance and the paint film intensity having utilized silane crosslinker to improve to film.
3, select the water soluble acrylic resin, improved glossiness and the water resistance of paint film.
