Description
Technical field the present invention relates to a kind of coating, and particularly a kind of protection for the skin surface and decoration, have super weather-proof, antiacid, stain resistant water-proof elastic dope, belongs to the chemistry painting industry technical field.
The current domestic whole elastic coating market of making a general survey of of background technology, most product is confined to possess snappiness, the feature of waterproof, and its weathering resistance and resistance to acid are poor.Because its weathering resistance is not strong, Acid Rain is poor, peel off in the wall surface coating integral body that causes apt to deteriorate of its paint film after rain drop erosion, or, because the difference of water ratio causes cracking or peels off, acid rain water just infiltrates metope the corrosion metope.These disadvantages that exist have at present had a strong impact on its protection to basic unit had and decorative effect.Therefore research has good contamination resistance, highly effective water-proof elastic dope significant of super weather-proof antiacid cun.
Summary of the invention the purpose of this invention is to provide a kind of super weather-proof antiacid highly effective water-proof elastic dope; this elastic coating not only has high-elastic waterproof; also there is the stain resistant performance; excellent weathering resistance and Acid Rain performance; tensile strength is good; can significantly improve the advantages such as cracking performance of body of wall, can protect the perfect decorative effect of buildings, play again lasting magnificent image appearance.
A kind of concrete component and part by weight of super weather-proof antiacid highly effective water-proof elastic dope are: water: 8-16%; Multifunctional assistant: 0.1-0.2%; Wetting agent: 0.1-0.2%; Dispersion agent: 0.4-0.8%; Defoamer: 0.3-0.6%; Propylene glycol: 1.5-3.0%; Rutile type Titanium Dioxide: 16-20%; Process white: 6-8%; Water-ground limestone: 5-8%; Opacifying polymers: 3-5%; Fluorine carbon emulsion: 28-35%; Elastic emulsion: 10-15%; Texanol:0.8-1.5%; Stain resistant auxiliary agent: 0.5-1%; Sanitas: 0.1-0.2%; Thickening material: 0.6-0.9%.
In general, the elasticity of elastic coating and the contamination resistance relation that is inversely proportional to, coating has lower contamination resistance under high-elastic state.The pollution channel of paint film mainly contains organism adhesion, electrostatic adhesion and imbedibility and pollutes.Filming of stain resistance excellence, from the angle that prevents from adhering to, hard, that anti-electrostatic effect good and surface smoothing has been considered to films, as the angle from resistant, the clean effect of hydrophilic film surface rainwater and surface uniform pollute and the rain mark that causes and non-the manifesting effect of spot have been considered to films.The present invention can form rigidity, the soap-free emulsion that contains special hydrophilic radical antistatic and surface smoothing is filmed, make paint film not only have snappiness also have antistatic, paint film is level and smooth, hydrophilic advantage, especially there is super weather-proof Acid Rain performance, thus make that elastic coating possesses that super-weathering resistance, Acid Rain are good, high-effective water-proof, have excellent water-resistance, the performance of stain resistant.
The 998FA fluorine carbon emulsion that the present invention uses, its organic fluorine element surpasses 6%, has splendid water tolerance, the weather resistance of overlength, anti-contamination, not xanthochromia.Have more the splendid performance of alkali resistant, Acid Rain, salt fog resistance.Paint film light, plentiful, good fluidity.
The elastic emulsion that the present invention uses is the soap-free emulsion containing special hydrophilic radical, there is again the performances such as excellent stain resistant in order to give the basic physical properties of filming, film coated surface is designed to wetting ability, its low temperature elasticity, sticking power is good, tensile strength is high, good with the color stuffing consistency, make the emulsion particle surface have effective hydrophilic functional group, thereby the water tolerance of making and wettability are simultaneously and deposit, and sticking power is good.
The Rutile type Titanium Dioxide that the titanium dioxide that the present invention uses is made for chlorination process, be 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 the 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 the 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 the coating film process, nanoparticle plays the 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, improve the 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 mainly contains newton-type nonionic polyoxyalkylene class rheology modifier and alkali swelling class thickening material.
In general, fluorocarbon coating is used widely in the every field of building, chemical industry, electric appliance and electronic industry, mechanical industry, aerospace industry, household supplies, and effect is better.
Below embodiment, be one embodiment of the present of invention.
The composition of super weather-proof antiacid highly effective water-proof elastic dope of the present invention (weight percent) and production technique are: the stirring at low speed stage adds 10% deionized water according to order, 0.15% multifunctional assistant, 0.1% wetting agent, 0.55% poly amic acid dipersant, 0.25% defoamer, 2% propylene glycol, 18% titanium dioxide 595, 7% fineness 800 purpose process whites, 8% fineness 1250 purpose water-ground limestones enter the high-speed stirring stage after all adding, and after stirring, speed lapping, to fineness≤50um, then adds successively the fluorine carbon emulsion AP5085 of 30 parts under stirring at low speed, 12% elastic emulsion, 4% Opacifying polymers, 0.8% Texanol, 0.8% stain resistant auxiliary agent NM-1, 0.2% defoamer NXZ, 0.15% sanitas MV, 0.4% newton-type nonionic polyoxyalkylene class rheology modifier thickening material DSX2000 and 0.25% alkali swelling thickening material TT935,4% deionized water and stirring is even, then stirring at low speed 10min, then through check, filter, the packing of weighing.
