Abstract
The invention relates to a super-weather-resistant elastic exterior wall coating which contains specific components in weight ratio: 10-20 percent of water, 0.1-0.2 percent of wetting agent, 0.4-0.8 percent of dispersing agent, 0.3-0.8 percent of defoaming agent, 1.5-3.0 percent of propylene glycol, 16-20 percent of rutile titanium dioxide, 6-8 percent of precipitated barium sulphate, 5-8 percent of ground calcium carbonate, 3-5 percent of opaque polymer, 22-25 percent of elastic emulsion, 20-24 percent of silicone acrylic emulsion, 0.5-1 percent of stain-resistant additive, 0.1-0.2 percent of preservative and 0.6-0.9 percent of thickening agent. The elastic coating is waterproof and high in elasticity, has the advantages of super weather resistance, good stain resistance, good tensile strength and the like, and can significantly improve cracking of wall bodies.
Description
Technical field the present invention relates to a kind of coating, and particularly a kind of protection for skin surface and decoration have high dirt resistance, hide the elastic coating of crackle ability, belong to chemistry painting industry technical field.
The current domestic whole elastic coating market of making a general survey of of background technology, most product is only limited to and possesses elastomeric feature, and its water tolerance and water-repellancy are poor, and tensile strength is low, and sticking power is general.Because it is not water-fast, non-watertight, at its paint film after rain drop erosion, will integral body peel off, or because the difference of water ratio causes cracking or peels off, rainwater just infiltrates metope corrosion metope.Because the contamination resistance of elastic coating is poor, construction is easily subject to being suspended in the dust in atmosphere afterwards, the pollution of oily matter is polluted coating surface simultaneously.For example publication number CN1737069A name is called the elastic coating relating in the patent application of " elastic coating and manufacture method for decoration of exterior wall " and also has the problems referred to above.These disadvantages of existing at present had a strong impact on that it has to the protection of basic unit and decorative effect.Therefore research has individual layer elastic coating significant of good contamination resistance, high-effective water-proof.
Summary of the invention the object of this invention is to provide a kind of super weather resisting elastic exterior coating, and this elastic coating not only has waterproof snappiness, and the contamination resistance, the tensile strength that have more super-weathering resistance, excellence are good, can significantly improve the advantages such as cracking performance of body of wall.
A kind of concrete component and part by weight of super weather resisting elastic exterior coating are:
Water: 10-20%; Wetting agent: 0.1-0.2%; Dispersion agent: 0.4-0.8%; Defoamer: 0.3-0.8%; 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%; Elastic emulsion: 22-25%; Organosilicon crylic acid latex: 20-24%; 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, anti-electrostatic effect good and surface smoothing has been considered to films, as the angle from decontamination, 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.
Organosilicon crylic acid latex used in the present invention is base-material, and organosilicon crylic acid latex is that the organosilane monomer that contains unsaturated link(age) and acrylic monomer are added to suitable auxiliary agent, by nucleocapsid, is coated the emulsion that polymerization technique is polymerized.Combine organosilicon fire-resistant, weathering resistance, chemical-resistant, hydrophobic, surface can low high tint retention, snappiness, the tack that is difficult for contaminative and acrylic resin.A kind of high weather-proof, high water-fast, resistant to pollution environment-friendly type building emulsion and coating.Organosilicon crylic acid latex, also has water resistant Bai Xingqiang, and contamination resistance is strong, has excellent weathering resistance simultaneously, is particularly suitable for high performance exterior coating.
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.
Thickening material used in the present invention mainly contains newton-type nonionic polyoxyalkylene class rheology modifier and alkali swelling class thickening material.
Generally be widely used in the civilian or commercial top-grade building outer surface of wall such as top-grade building industry ，Ru school, hospital, villa.
Below embodiment, be one embodiment of the present of invention.
The composition of a kind of super weather resisting elastic exterior coating of the present invention (weight percent) and production technique are: the stirring at low speed stage adds the deionized water of 11 parts according to order, 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 propylene glycol of 2.5 parts, the titanium dioxide 595 of 18 parts, 7 parts of fineness 800 object process whites, 8 parts of fineness 1250 object water-ground limestones, after all adding, enter the high-speed stirring stage, after stirring, speed lapping is to fineness≤50um, then under stirring at low speed, add successively the elastic emulsion AP5085 of 24 parts, the organosilicon crylic acid latex of 19 parts, the Opacifying polymers Unihub of 4 parts, the stain resistant auxiliary agent of 0.8 part, the defoamer of 0.15 part, the sanitas of 0.15 part, the thickening material of 0.4 part and 0.25 part of thickening material, the water of 3.95 parts stirs, stirring at low speed 10min again, again through check, filter, the packing of weighing.
