Abstract
The invention provides a mould-proof, anti-alga and super-weatherability silicone acrylic emulsion external wall paint. The external wall paint comprises the following specific components in percent by weight: 10-15 percent of water, 0.1-0.2 percent of a multifunctional additive, 0.1-0.2 percent of a wetting agent, 0.3-3.8 percent of a dispersing agent, 0.1-0.5 percent of an antifoaming agent, 20-25 percent of rutile titanium dioxide, 5-8 percent of heavy calcium carbonate, 5-8 percent of wollostonite, 5-8 percent of kaolinite, 3-5 percent of opaque polymer, 30-35 percent of acrylic latex, 0.5-1 percent of a stain resistance additive, 0.8-1.5 percent of Texanol, 0.1-0.3 percent of a mould inhibitor, and 0.6-0.9 percent of a thickening agent. The external wall paint not only has extremely good weatherability, stain resistance and water resistance, but also has mould-proof and anti-alga functions.
Description
Technical field the present invention relates to a kind of coating, and particularly a kind of protection for skin surface and decoration have very excellent high-weatherability and contamination resistance and organosilicon crylic acid latex exterior coating that can mildew-resistant algae-resistant, belong to chemistry painting industry technical field.
Background technology is along with the development of domestic economy, real estate industry has also entered the high speed development stage thereupon, external wall decorative material is in the past eliminated because of the drawback of cost and use gradually as ceramic tile, stone material, plastic-aluminum sheet material etc., exterior coating is various with its easy construction, color, asepsis environment-protecting etc. is a little more and more applied in the middle of decoration of exterior wall, and has obtained people's approval.
Exterior coating is exposed in atmospheric environment, naturally changing of the weather such as will pass through wind, Exposure to Sunlight, drench with rain, and because environmental pollution is day by day serious, dust and suspended matter in atmosphere are more, can easily make coating generation efflorescence, variable color, peel off, be infected with the phenomenons such as spot and lose original decorative effect, thereby affect the attractive in appearance of buildings appearance.Tackle complex environment External Wall coating products like this and have higher requirement, the weathering resistance and the contamination resistance that strengthen exterior coating product are the most important things.
Summary of the invention the object of this invention is to provide the super weather-proof organosilicon crylic acid latex exterior coating of a kind of mildew-resistant algae-resistant, and this exterior coating is very excellent weathering resistance, contamination resistance and water tolerance not only, and has the function of mildew-resistant algae-resistant.
Concrete component and the part by weight of the super weather-proof organosilicon crylic acid latex exterior coating of a kind of mildew-resistant algae-resistant of the present invention are: water: 10-15%; Multifunctional assistant: 0.1-0.2%; Wetting agent: 0.1-0.2%; Dispersion agent: 0.3-0.8%; Defoamer: 0.1-0.5%; Rutile type Titanium Dioxide: 20-25%; Water-ground limestone: 5-8%; Wollastonite: 5-8%; Kaolin: 5-8%; Opacifying polymers: 3-5%; Organosilicon crylic acid latex: 30-35%; Stain resistant auxiliary agent: 0.5-1%; Texanol:0.8-1.5%; Mould inhibitor: 0.1-0.3%; Thickening material: 0.6-0.9%.
In general, the life-span of exterior coating is decided by weathering resistance and the stain resistant performance of coating.Along with being on the rise of air environmental pollution, and the outer wall coating being exposed under nature complex environment is just standing acid test further, and especially, for the Highrise buildings in city, floor is higher, and the cost that whitewashes, cleans body of wall is just higher.
The emulsion that the present invention uses is a kind of by silane coupler modified organosilicon crylic acid latex, has satisfactory stability.Organosilyl adding, makes paint film according to water good permeability, and weathering resistance, water tolerance, stain resistant performance are splendid, and has greatly improved the sticking power of paint film and base material.
The Rutile type Titanium Dioxide that the titanium dioxide that the present invention uses is made for chlorination process, is characterized in having high gloss, fabulous color, opacifying power and dispersed and good exterior durability.Its performance and opacifying power, weathering resistance and the chalking resistance close relation of filming.
The dispersion agent that the present invention uses is low-molecular-weight polypropylene amine acid salt dispersion agent, can significantly improve concentration and the stability thereof of color stuffing dispersion pulp, by this dispersion agent, can surround a layer charge at color stuffing particle surface, make repulsion mutually between particle, thereby reach the effect of stable slurry.
The Opacifying polymers that the present invention uses is hollow polymer spheroid, can show extremely strong covering performance, improve coating contamination resistance (dirt pickup resistant), strengthen outdoor tint retention.
The stain resistant auxiliary agent that the present invention uses is for nano modification stain resistant auxiliary agent, and in coating film process, nanoparticle plays hinge point effect, and the organic polymer hinge of line style is reticulated to structure, improves film coated surface hardness; The pore dimension of filming by reduction, improves smooth coating degree; By the reduction static charge of filming, reduce the absorption of atmospheric dust; Making to film possesses good self-cleaning, has improved the stain resistant performance of coating.
The mould inhibitor that the present invention uses is hypotoxicity mould inhibitor, and effectively bacteria growing inhibiting breeding, prevents the growth of metope algae.
Thickening material used in the present invention mainly contains newton-type nonionic polyoxyalkylene class rheology modifier and alkali swelling class thickening material.
Production technique of the present invention is mixed the component of above-mentioned weight ratio at normal temperatures, under stirring at low speed, add part water, multifunctional assistant, wetting agent, dispersion agent, early stage defoamer, propylene glycol, titanium dioxide, coarse whiting, wollastonite, kaolin, after high speed dispersion, be ground to after slurry fineness≤50um, stirring at low speed adds Opacifying polymers, emulsion, Texanol, later stage defoamer, mould inhibitor, thickening material, excess water, meet the requirements of after viscosity, stirring at low speed 10min again, then through checking, filter, weigh packing.
Below embodiment, be one embodiment of the present of invention.
