Abstract
The invention provides a high-level elastic moldproof coating for an external wall, and belongs to the technical field of chemical coatings. The high-level elastic moldproof coating is applied to the surface of the external wall of a building and has water resistance, alkali resistance, stain resistance and unique moldproof functions. The moldproof coating for the external wall specifically comprises the following components in percentage by weight: 16 to 22% of water, 0.1 to 0.2% of S5O6, 0.3 to 0.6% of dispersing agent, 0.05 to 0.07% of wetting agent, 2 to 2.15% of anti-foaming agent, 18 to 23% of titanium dioxide, 8 to 12% of precipitated barium sulphate, 4 to 6% of kaolin, 5 to 8% of pure acrylic emulsion, 5 to 8% of elastic emulsion, 28 to 33% of antifreezing agent, 0.05 to 0.08% of coalescing agent, 1.55 to 2% of mildew preventive, 0.4 to 0.6% of flatting agent, a proper amount of pH modifier, and a proper amount of thickening agent. The high-level elastic moldproof coating for the external wall is principled in that a formed coat is given the elastic resistance to cracking, alkali resistance, stain resistance, ageing resistance, covering performance and other functions due to the physical and chemical effects of rutile titanium dioxide, emulsion and mildew preventive and the like, and thus the mold growth is inhibited.
Description
Technical field
The present invention relates to a kind of coating, particularly the water-borne coatings of the performance such as a kind of water-fast, alkaline-resisting, stain resistant for skin surface, Elastic reactance cracking, has unique antimildew function, belongs to chemistry painting industry technical field.
Background technology
Easily polluting mouldy and easy to crack phenomenon on building field ubiquity skin surface, is a new public relation of building field.Currently make a general survey of domestic whole Coating Market; exterior coating kind is more; but mainly with possessing protection, decoration functions is main, antimildew function coating just has the performances such as water tolerance, alkali resistance, stain resistant and better simply mildew-resistant, it is weak that the anti-algae performance of mildew-resistant of its exterior coating shows slightly.Therefore to have the exterior wall mould-repellant coating of the anti-algae property of mildew-resistant significant in research.
Summary of the invention
The object of this invention is to provide a kind of skin topcoating, this coating has good permeability, excellent water tolerance, alkali resistance, weathering resistance; Scrubbing resistance, stain resistant performance are good, and Elastic reactance cracking performance is strong; Asepsis environment-protecting, nuisanceless, strong adhesion, and have unique antimildew function, can effectively prevent that metope from producing mildew because of ambient air high humidity of living in.
Concrete component and the part by weight of high-grade elastic exterior wall mould-repellant coating of the present invention are:
Water 16-22%; Sterilant: 0.1-0.2%; Dispersion agent: 0.3-0.6%; Wetting agent: 0.05-0.07%; Defoamer: 2-2.15%; Titanium dioxide: 18-23%; Process white: 8-12%; Kaolin: 4-6%; Pure-acrylic emulsion 5-8%; Elastic emulsion: 5-8%; Frostproofer: 28-33%; Film coalescence aid: 0.05-0.08%; Mould inhibitor: 1.55-2%; Flow agent: 0.4-0.6%; PH value conditioning agent: appropriate; Thickening material: appropriate.
Process white used in the present invention, is the protection walls material that anti-radioactive rays are used, and is applied in building external paint, can improve fast light, weather-proof, chemically-resistant and electrochemical corrosion and the product decoration effect of product, strengthens the resistance to impact shock of coating.Titanium dioxide is had to synergism, and then reduce the consumption of titanium dioxide.
Kaolin used in the present invention, its refractoriness is high, can reach 1770～1790 ℃.In, low plasticity, the insulativity that tool is good and chemical stability, the preferably physico-chemical property such as resistivity against fire.
Pure-acrylic emulsion used in the present invention is base-material, is raw material because its raw material all adopts CALCIUM ACRYLATE emulsion, and the outdoor weatherability excellence of acrylate, therefore have and have excellent weather resistance, waterproof, stain resistant, high gloss, it is that ageing resistance and Bao Se gloss retention are strong for dragon, can mould fungus inhibition growth.
Rutile titanium white powder used in the present invention, has kept crystalline structure fine and close and stable, and stronger opacifying power and reducing power, have good dispersiveness and good exterior durability.Opacifying power, weathering resistance and the chalking resistance close relation of its performance and film.
Aqueous solution type elastic emulsion used in the present invention; the performances such as its excellent rebound resilience, snappiness, resistance to dirt retention and UV resistant, can cover body of wall hair line effectively, and the anti-cracking performance of metope is extremely strong; both protected and beautified the magnificent of body of wall, again asepsis environment-protecting, nuisanceless.
Dry film mould inhibitor used in the present invention; high with good, the pH value of consistency and the light stability of formula; rheology on color and liquid does not affect; mould and algae are had to high reactivity; can prevent that fungi from growing in coating; protection outer wall coating, not by bacterium and fungi infestation, therefore has unique antimildew function.
The object of the invention is in order to utilize emulsion and the consistency of dry film mould inhibitor in batching, make this high-grade elastic exterior wall mould-repellant coating there is water-fast, alkaline-resisting, weather-proof, stain resistant and snappiness anti-cracking performance, both strong ageing resistance and the opacifying power of this coating had been brought into play, the outstanding mould-repellant coating that embodies can be grown by mould fungus inhibition again, protect look gloss retention good, under optical effect, make exterior wall mould-repellant coating reach and there is unique antimildew function.
[0013] in general, elasticity mould-repellant coating is water-fast, alkaline-resisting, stain resistant, Elastic reactance cracking, mould proof property are strong, has successfully been applied to a lot of fields, and as fields such as medicine equipment, medical furniture, pottery, buildings, effect is better.
