Technical field
The present invention relates to a kind of coating composition, anti-foul easy-cleaning product and preparation method thereof; Relate in particular to a kind of anti-foul easy-cleaning product, particularly aluminium-plastic panel that is used on aluminium-plastic panel forming coating composition that anti-soil is prone to the cleaning coating, prepares the method for goods and have the coating that makes by said composition by said composition.
Background technology
Aluminium-plastic panel is a kind of novel finishing material that is used for indoor and outdoor, can be used for curtain wall, places such as direction board.Aluminium-plastic panel unites two into one with the light weight of plastics is inexpensive owing to the texture that metal is noble, be easy to processing characteristics, becomes a kind of emerging building and ornament materials rapidly, and extends to the advertising sign industry gradually.Aluminium-plastic panel mainly is made up of intermediary Vilaterm and two-layer up and down aluminium sheet.This structure makes aluminium-plastic panel have a lot of traditional decoration materials, glass for example, and ceramic tile, not available property such as timber, anticorrosive like shock resistance, weight is lighter etc.As a rule, be used for outdoor aluminium-plastic panel surface and also can apply one deck fluorocarbon coating, for example pvdf (PVDF) is used for indoor aluminium-plastic panel and then can applies one deck polyester coating.
But, generally, after through long-time the placement; Even those have applied PVDF, the aluminium-plastic panel surface with certain antifouling property all can be by dust, and greasy dirt etc. stain and dirty; Thereby the appearance that influence is decorated needs regularly these outdoor decoration materials to be carried out cleaning.Therefore, need to develop a kind of long-time anti-soil that has, keep the aluminium-plastic panel material that self cleans.
Summary of the invention
An object of the present invention is to provide a kind of aluminium-plastic panel with long-term anti-soil, performance easy to clean, another object of the present invention provides a kind of compsn that long-term anti-soil and performance easy to clean can be provided for aluminium-plastic panel.
The contriver unexpectedly finds, through at the specific anti-soil of aluminium-plastic panel surface-coated one deck inventor invention, be prone to the cleaning coating, can make the long-term anti-soil of aluminium-plastic panel and easy to clean.And, utilize existing composited aluminum and plastic decking finishing material production line, apply easy cleaning coating of the present invention continuously at the hard metal substrate surface, hot pressing subsequently can make long-term anti-soil and aluminium-plastic panel of the present invention easy to clean.Surprised especially is that coating composition of the present invention not only can form a uniform coating on the aluminium-plastic panel surface of ultra-low surface energy, and this coating can still be kept good long-term anti-soil, be prone to sanitary characteristics after standing above-mentioned hot pressing.
First aspect of the present invention provides a kind of compsn, and said compsn comprises:
The continuous liquid phase of water-based;
Be dispersed in the silicon dioxide granule in the continuous liquid phase of said water-based, the volume average particle size of wherein said silicon dioxide granule is below 150 nanometers;
The aliphatic polyurethane particle; With
By the weight of said silicon dioxide granule, be higher than 0% and be lower than the AEO of 15 weight % and/or polyether-modified siloxanes;
Wherein, the pH of said compsn is not less than 5, and the weight ratio of said silicon dioxide granule and said urethane is in 4: 1 to 9: 1 scope.
Second aspect of the present invention provides a kind of method for preparing goods, and said method comprises compsn recited above is coated on the major surfaces of substrate.
The 3rd aspect of the present invention provides a kind of goods, and said goods comprise:
Substrate; With
The coating that on the major surfaces of said substrate, forms with compsn recited above.
Coating by compsn of the present invention forms can obviously be improved the easy cleaning function that has composited aluminum and plastic decking now; Make dust, flue gas etc. be difficult in this coatingsurface deposition; Use the water that does not contain sanitising agent just can easily remove the surface deposition dirt simultaneously; Prolong cleaning cycle, reduce the cleaning cost.
Description of drawings
Fig. 1 shows the structural representation according to the aluminium-plastic panel of one embodiment of this invention.
Embodiment
Among the present invention, only if specialize, term " aluminium-plastic panel " is meant and comprises the plastics sandwich layer, the matrix material of aluminium alloy layer.
Only if specialize, term " median size ", " particle size ", " size of particles ", " particle size " are meant the particulate diameter.
Only if specialize, term " nano silicon " is meant that median size is the silicon-dioxide below 150 nanometers.
Only if specialize, term " the continuous liquid phase of water-based " is meant the liquid of the water that contains 5% weight at least.
First aspect of the present invention provides a kind of compsn, and said compsn comprises:
The continuous liquid phase of water-based;
Be dispersed in the silicon dioxide granule in the continuous liquid phase of said water-based, the volume average particle size of wherein said silicon dioxide granule is below 150 nanometers, preferred 4-75 nanometer;
The aliphatic polyurethane particle; With
By the weight of said silicon dioxide granule, be higher than 0% and be lower than the AEO of 15 weight % and/or polyether-modified siloxanes;
Wherein, the pH of said compsn is not less than 5, and the weight ratio of said silicon dioxide granule and said urethane is in 4: 1 to 9: 1 scope.
Nano silicon has good anti-soil and easy clean-up performance.But the contriver finds, when the aqueous liquid dispersion that will contain nano silicon oxide is coated on the aluminium-plastic panel, is difficult to form effective coating, more is difficult to obtain evenly level and smooth coating of outward appearance, even formed coating, also is easy to come off.The contriver unexpectedly finds, adopts the compsn of above-mentioned prescription can be easily for example to form one on the aluminium-plastic panel on the surface of ultra-low surface energy firmly and the even level and smooth coating of outward appearance, and the anti-soil of coating and other performances are unaffected.And even through hot pressing, the coating that is formed by the present composition also can keep good anti-soil, easy clean-up performance.
Silicon-dioxide is known in the field.For example, can be purchased with the form (colloidal sol) that is scattered in the aqueous medium.For example, with trade(brand)name LUDOX from E.I.du Pont de Nemours & Co., Wilmington; DE, with trade(brand)name NYACOL from Nyacol Co., Ashland; MA; Or with trade(brand)name NALCO from Nalco Chemical Co., the colloidal sol of silicon-dioxide in water or alcohol solution that Naperville, IL buy.
Aliphatic poly ethenoxy group ethers and polyether modified siloxane can use as wetting agent in the present composition separately or together.Wetting agent also can combine other tensio-active agents to use.The wetting agent that is suitable for includes but not limited to the aliphatic poly ethenoxy group ether AEO-7 and the aliphatic poly ethenoxy group ether AEO-9 of the Dow Chemical Company; The polyether modified siloxane BYK346 of BYK company; Polyether-modified YSR 3286 BYK331; Polyether-modified YSR 3286 BYK378, polyether-modified YSR 3286 interpolymer BYK333.Its consumption is no more than 15 weight % by the weight of said silicon dioxide granule, preferred 3%-12%, more preferably 5%-10%.
