Abstract
The invention relates to an organosilicon self-cleaning environmental-friendly external-wall coating material. The external-wall coating material is prepared from the specific ingredients in percentage by weight: 20-25% of water, 0.1-0.3% of multifunctional auxiliaries, 0.05-0.1% of wetting agent, 0.1-0.3% of dispersant, 0.1-0.3% of defoamer, 10-15% of organosilicon active latex, 60-65% of latex, 1-2% of Texanol, 0.1-0.2% of antiseptic and 0.6-0.9% of thickener. The external-wall coating material has good weather and contamination resistance, has good super hydrophilicity, can play a role in self-cleaning, and is energy-saving, environmental-friendly, non-toxic and harmless.
Description
Technical field the present invention relates to a kind of coating; be particularly related to a kind of protection for skin surface and decoration; the organosilicon environment-friendly exterior coating with " self-cleaning " function with splendid high-weatherability and stain resistant performance, belongs to chemistry painting industry technical field.
Background technology building coating, as a kind of novel building material product, has unique advantage: first, from decoration functions, the decorative effect that building coating is lucuriant in design, colourful, meets the pursuit of current people's individual character words.Secondly, it more easily upgrades, and cost is low, and people can cover with paint, lacquer, colour wash, etc. very easily again, meet the needs of the permanent Chang Xin of building external decoration.Again, consider from constructing, building coating can be coated on buildings easily and efficiently, and operating efficiency is high, without potential safety hazard, thereby is more and more applied in the middle of the decorations of external wall.
Building external paint, because coating is exposed in atmospheric environment, stand wind, Exposure to Sunlight, drench with rain, the natural weather such as haze changes, in recent years because environmental pollution is day by day serious, exceedingly odious weather occurs now and then, and the dust in atmosphere, suspended matter and oxynitride are more, can more easily make coating generation efflorescence, variable color, peel off, be infected with the phenomenons such as spot and lose original decorative effect, thus affect the attractive in appearance of buildings appearance.And the rise of Highrise buildings in recent years, has further requirement to the performance of building external paint.The weathering resistance and the stain resistant performance that how to improve exterior coating product are one of directions of research exterior coating development.
Summary of the invention the object of this invention is to provide the self-cleaning environmental protection exterior coating of a kind of organosilicon, and this exterior coating is good weather-proof, contamination resistance not only, but also has Superhydrophilic, can play " self-cleaning " effect, energy-conserving and environment-protective, Nonpoisonous, non-environmental-pollution.
Concrete component and the part by weight of the self-cleaning environmental protection exterior coating of a kind of organosilicon of the present invention are: water: 20-25%; Multifunctional assistant: 0.1-0.3%; Wetting agent: 0.05-0.1%; Dispersion agent: 0.1-0.3%; Defoamer: 0.1-0.3%; Organosilicon lotus property emulsion: 10-15%; Emulsion: 60-65%; Texanol:1-2%; Sanitas: 0.1-0.2%; 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 use of the organosilicon lotus property latex in the present invention, utilize Si-OH and-the multiple cross-linked chemical reaction of OH-, can make coating there is extremely low surface tension, thereby maintain splendid hydrophobic effect, make coating there is good weathering resistance and contamination resistance.
The organic siloxane modified polymerized emulsion that the emulsion that the present invention uses is novel special construction, in drying and forming-film wherein between Si-OH and and base material on-there is multiple cross-linked chemical reaction in OH-, can make coating have extremely low surface tension, can keep splendid hydrophobic effect, stain resistant performance is good, and there are good Compositional type, stable performance with other emulsions.
The emulsion that the present invention uses is acrylate copolymer emulsion, in order to give the basic physical properties of filming, there is again the performances such as excellent stain resistant, film coated surface is designed to wetting ability, make emulsion particle surface have effective hydrophilic functional group, thereby the water tolerance of making and wettability while also deposit, and sticking power is good.
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.
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,, stirring at low speed adds organosilicon lotus property latex, benzene emulsion, Texanol, later stage defoamer, sanitas, 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.
Composition (weight percent) and the production technique of the self-cleaning environmental protection exterior coating of a kind of organosilicon of the present invention are: the stirring at low speed stage adds the deionized water of 15 parts according to order, the multifunctional assistant AMP-95 of 0.3 part, the wetting agent X405 of 0.1 part, 0.55 part of poly amic acid dipersant PR03, the defoamer NXZ of 0.15 part, the titanium dioxide 595 of 21 parts, 7 parts of fineness 800 object water-ground limestones, 5 parts of fineness are 800 object wollastonites, 5 parts of fineness are 1250 object kaolin, enter the high-speed stirring stage after all adding, and after stirring, speed lapping, to fineness≤50um, then adds successively 10 parts of organosilicon lotus property latex 8861 under stirring at low speed, the benzene emulsion 998A of 25 parts, the Texanol of 0.8 part, the defoamer NXZ of 0.15 part, the sanitas MV of 0.15 part, the newton-type nonionic polyoxyalkylene class rheology modifier thickening material DSX2000 of 0.5 part and 0.3 part of alkali swelling thickening material TT935, the deionized water and stirring of 9 parts is even, then stirring at low speed 10min, then through check, filter, the packing of weighing.
Self-cleaning its indices of environmental protection exterior coating of a kind of organosilicon 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 splendid weather-proof, stain resistant, water-fast, alkaline resistance properties, and due between Si-OH and and base material on-there is multiple cross-linked chemical reaction in OH-, coating has extremely low surface tension, can keep splendid " hydrophobic " effect, make product there is " self-cleaning " function, made the pollutent on outer wall coating easier by rain drop erosion, thereby protected outer wall decorative effect, extended exterior wall work-ing life, saved cost.This product is widely used on the decoration of exterior wall of house, hotel, school, hospital etc., and customer response is respond well.
