Abstract
The invention discloses silica sol high-permeability multifunctional transparent finish-coat paint. The finish-coat paint concretely comprises the following constituents by weight percentage: 20 to 25 percent of water, 20 to 25 percent of silica sol, 50 to 55 percent of styrene-acrylic emulsion, 2.5 to 3 percent of butyl cellosolve, 0.5 to 1 percent of a stain resistant aid, 0.1 to 0.2 percent of a preservative, and 0.2 to 0.4 percent of a thickening agent. The finish-coat paint not only has good permeability, weather resistance and water resistance, but also is provided with excellent stain resistance, and can effectively protect interior coating.
Description
Technical field the present invention relates to a kind of coating, and particularly a kind of protection for skin surface and decoration have the high infiltration of a kind of silicon sol multifunctional transparent finishing paint of hypertonicity, weathering resistance, stain resistant performance, belong to chemistry painting industry technical field.
Background technology building external paint is lucuriant in design with it, easy construction, the ornamental advantage such as strong and be more and more used in the middle of the decorations of exterior wall.The use of exterior coating, is not only confined on flat painting product lucuriant in design.In recent years, the strong coating products of stereo decoration sense such as textured coating, elastic napping coating, true mineral varnish, sand texture coating is widely used.Exterior coating, because coating is exposed in atmospheric environment, stand wind, Exposure to Sunlight, drench with rain, the Changes in weather such as haze, 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.Therefore especially the strong paint coatings of stereo decoration sense more becomes easily infected by spot, studies the translucent cover lac varnish of a kind of hypertonicity, high weather-proof, high dirt resistance for having great significance the work-ing life that extends exterior coating.
Summary of the invention the object of this invention is to provide the high infiltration of a kind of silicon sol multifunctional transparent finishing paint, and this finishing paint not only has good perviousness, weathering resistance, water tolerance, and has good stain resistant performance, can effectively protect interior trim coating.
Concrete component and the part by weight of the high infiltration of a kind of silicon sol of the present invention multifunctional transparent finishing paint are: water: 20-25%; Silicon sol: 20-25%; Benzene emulsion: 50-55%; Butyl glycol ether: 2.5-3%; Stain resistant auxiliary agent: 0.5-1%; Sanitas: 0.1-0.2%; Thickening material: 0.2-0.4%.
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 use of the silicon sol in the present invention, makes finishing paint have good perviousness, uses with emulsion collocation, can form the ventilative of high compactness and film, and makes coating have good perviousness, weathering resistance, water tolerance and stain resistant performance.
The soap-free polymerization pure-acrylic emulsion that the emulsion that the present invention uses is a kind of ultra-fine grain diameter, has outstanding water tolerance and anti-whiting, especially at high pH value, obtains and on base material, has outstanding alkali burnout resistance; And its particle diameter is ultra-fine, can make it be more prone to be penetrated in the middle of base material, there is outstanding closed performance and finish paint sticking power.
The silicon sol that the present invention uses is to take the poly-metasilicic acid colloidal solution of inorganic polymer that water is disperse phase, and its activity is higher, and perviousness is strong especially, is easy to be penetrated into base material inner and be attached to substrate surface.With the crosslinked film forming of soap-free polymerization pure-acrylic emulsion, there is good perviousness, closure and ventilation property.
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.
Thickening material used in the present invention is mainly alkali swelling class thickening material.
Production technique of the present invention is mixed the component of above-mentioned weight ratio at normal temperatures, and first emulsion being adjusted to pH value is 9 o'clock, adds silicon sol, forms mixing solutions.Under stirring at low speed, add water, butyl glycol ether, nanometer stain resistant auxiliary agent, mould inhibitor, thickening material, meet the requirements of after viscosity, then stirring at low speed 10min, then through checking, filter, weigh packing.
Below embodiment, be one embodiment of the present of invention.
Composition (weight percent) and the production technique of the high infiltration of a kind of silicon sol of the present invention multifunctional transparent finishing paint are: 50 parts of soap-free polymerization pure-acrylic emulsion AD12S are adjusted to pH value to 9, under stirring at low speed, add 25 parts of silicon sol JNF solution, form mixing solutions, stirring at low speed 10 minutes is stand-by, and the stirring at low speed stage adds 21.6 parts of deionized waters, 2.5 parts of butyl glycol ethers, 0.5 part of nanometer stain resistant auxiliary agent, 0.2 part of mould inhibitor, 0.2 part of thickening material according to order; Stirring at low speed 10min again, then through checking, filter, weigh packing.
Its indices of acrylic wall paint of making according to the present invention all reaches GB/T9755-2001 about the requirement of exterior wall coating material of synthetic resin emulsion defined; product has good weathering resistance, contamination resistance, water tolerance and hypertonicity; and the use due to silicon sol; film and there is good perviousness; be used in conjunction with pure-acrylic emulsion, formed fine and close highly air-permeable and filmed, effectively protected outer wall decorative effect; extend exterior wall work-ing life, saved cost.The outer cover that this product is widely used textured coating, true mineral varnish, sand texture coating, elastic napping coating is used, and has effectively protected coating texture.Customer response is respond well.
