Abstract
The invention discloses a water-based super weather-resistant modified silicone-acrylic acid metal paint coating. The water-based super weather-resistant modified silicone-acrylic acid metal paint coating mainly comprises, by mass, 75 to 85 parts of water-based organosilicon modified acrylic emulsion, 5 to 8 parts of aluminium paste, 0.01 to 0.03 part of butyl cellosolve), 1 to 5 parts of a levelling agent, 1 to 5 parts of a film forming auxiliary agent and 8 to 15 parts of water. The water-based super weather-resistant modified silicone-acrylic acid metal paint coating can be used for one-step spraying; the surface of obtained paint film is compact, bright and smooth; and the obtained paint film possesses high tenacity, and excellent impact resistance and stain resistance. Coating of the water-based super weather-resistant modified silicone-acrylic acid metal paint coating is capable of obtaining endurance, acid and alkali resistance, effective inhibition on growth of algae and fungus, and environmental protection performance. The properties can be maintained unchanged under long-term complex weather conditions for more than 3000 hours; simulation of decorative effect of aluminium-plastic panel can be realized; dazzling metallic luster can be observed; it is difficult for dust to accumulate on the paint film; and the paint film is clean and beautiful.
Description
Technical field
The present invention relates to a kind of composition that is coated in article surface, relate in particular to super weather-proof modified silicon the third metallic paint coating of a kind of water-based, there is the characteristic of aluminium plastic sheet-imitation, be specially adapted to decorating outer wall of building.
Background technology
During outside the building wall is decorated, the general exterior coating conventionally adopting, lacks attractive in appearance and shows the demands such as individual character.And thick-layer is decorated, such as: ceramic tile or marble etc., there is waste resource, do not meet energy-conserving and environment-protective requirement, and the defects such as danger of falling from high altitude.There is again the defects such as poisonous and harmful, not environmental protection in solvent based coating.The technical problem existing for solving existing coating, modified paint arises at the historic moment, and it mainly adopts water-borne acrylic resin is matrix, adds low levels silicon oil, and resin property is changed, can physical crosslinking, again can chemically crosslinked.
Chinese invention patent ZL200910043101.6 discloses a kind of spraying type fluorocarbon metallic paint and the application on architecture aluminium alloy profile thereof.This metallic paint is comprised of following component and weight percent: polyvinylidene difluoride (PVDF) 20-60, thermosetting acrylic resin 10-30, aminoresin 10-20, aluminium-silver slurry 5-10, filler 5-20, two or more mixed type solvent 10-60, there is easy construction, good weatherability, can greatly improve time limit of service out of doors of aluminium after coating and have good outward appearance.
Chinese invention patent application 201110209618.5 discloses a kind of single component nylon metallic paint and preparation method thereof, this metallic paint comprise the resin of 5wt%-7wt% silver powder, 40wt%-60wt%, the solvent of the cellulose acetate butyrate of 6wt%-10wt%, 20wt%-40wt%, the anti-settling wax slurry of the adhesion promoter of 2wt%-8wt% and 4wt%-10wt%.This metallic paint has been realized saving operation, the technique effect such as cost-saving and easy to use.
Although numerous contrivers use various technology to improve metallic paint different aspect, but the metallic paint of prior art is mostly solvent based coating, contain more organic solvent (as: dimethylbenzene), not only there is inflammable and explosive potential safety hazard, also have the problems such as poisonous and harmful, infringement health and contaminate environment.Therefore, for safety and environmental angle, and strengthen the requirement that External Wall beautifies, still need metallic paint coating to improve.
Summary of the invention
One object of the present invention is to provide a kind of water-based super weather-proof modified silicon the third metallic paint coating, to give skin with metalluster, strengthens aesthetic property and the uniqueness of building, and imitation effect is more true to nature, more durable.
Another object of the present invention is to provide a kind of water-based super weather-proof modified silicon the third metallic paint coating, and the surface compact of coating is bright and clean, further improves toughness, shock resistance and contamination resistance.After coating applies, there is weather resistance, acid and alkali-resistance, effectively prevent the growth of algae and mushroom, and the characteristic such as environmental protection.
Another object of the present invention is to provide a kind of water-based super weather-proof modified silicon the third metallic paint coating, strengthens the spraying application performance of coating.
Super weather-proof modified silicon the third metallic paint coating of a kind of water-based provided by the invention, by massfraction, mainly comprises 75-85 waterborne organic silicon modified acrylic acid emulsion, 5-8 aluminium paste, 0.01-0.03 butyl glycol ether, 1-5 flow agent, 1-5 film coalescence aid and 8-15 water.
Aluminium paste of the present invention, preferably model W301(Huizhou City Pai Site Industrial Co., Ltd.)
Film coalescence aid of the present invention preferably 2,2,4-trimethylammonium-1.3 pentanediol mono isobutyrate (Texanol
tM，Yi scholar Man), be the film coalescence aid using in a kind of emulsion paint, volatilization is slow, water insoluble.It can give the characteristic of the many excellences of coating, as: scrub resistance, color developing and stability in storage etc.Texanol
tMafter joining in emulsion paint, it is aggregated thing latex particle adsorbs, and makes latex particle deliquescing, thereby can complete fusion in drying varniss process.Flow agent of the present invention, preferably model P3290(
, BASF).
Super weather-proof modified silicon the third metallic paint coating of water-based provided by the invention, also comprises appropriate sterilant, anti-sagging agent, wetting agent and dispersion agent etc., and " in right amount " is interpreted as the amount that those skilled in the art adopt conventionally.
Sterilant of the present invention, preferred consumption is massfraction 0.1-0.5, preferably model SPT-B(San Bo biochemical technology (Shanghai) Co., Ltd.).
Wetting agent of the present invention, preferred consumption is massfraction 0.1-1.0, preferably model BYK348(Bi Ke company).
Dispersion agent of the present invention, preferred consumption is massfraction 1.0-1.5, preferably model BYK180(Bi Ke company).
Anti-sagging agent of the present invention, preferred consumption is massfraction 0.1-0.5, preferably model BYK420(Bi Ke company).
The beneficial effect that technical solution of the present invention realizes:
Super weather-proof modified silicon the third metallic paint coating of water-based provided by the invention, solved fugitive color, tarnish, easily turn white turn black or turn to be yellow, without individual character, the problem such as smell is pungent and hazardous and noxious substances exceeds standard, successfully realize the requirement of excellent performance and environmental protection and energy saving.Coating can a spraying application, and coating surface densification is bright and clean, is rich in toughness, has outstanding shock resistance and remarkable contamination resistance.Thereby solved the problems during skin is decorated, as: the danger of falling from high altitude, assortment list mediation poor durability.
After testing, super weather-proof modified silicon the third metallic paint coating of water-based making acid rain resistant, ageing-resistant, prevent paint film fade or turn white, the equal excellent property in aspect such as shock resistance and contamination resistance, wherein also conformance with standard of contained limits of harmful substances.After coating applies, there is weather resistance, acid and alkali-resistance, effectively prevent the growth of algae and mushroom, and the characteristic such as environmental protection.Under long-term complicated weather condition changing conditions, performance still remains unchanged, and laboratory tolerance is more than 3000 hours unchanged, and lacquer painting can reach the decorative effect of aluminium plastic sheet-imitation, can shine dazzling metalluster, and dust is difficult for being accumulated in lacquer painting, clean attractive in appearance.
