Environment-friendly aqueous nano transparent UV shielding coating for highlight furniture and preparation method thereof

Abstract

The invention relates to an environment-friendly aqueous nano transparent UV shielding coating for highlight furniture. The coating comprises the following components: deionized water, a dispersing agent, a nano inorganic slurry, titanium dioxide, a thickener, acrylic modified waterborne polyurethane, a preservative, a pH regulator and sodium hexametaphosphate. A blending method is employed to prepare the environment-friendly aqueous nano transparent UV shielding coating. The method is as below: taking a certain amount of an acrylic modified aqueous polyurethane emulsion E-106 and adding 0.1% of nano TiO2 mixed aqueous dispersion with stirring; stirring evenly with a high speed mixer with a stirring speed of 1000 r / min for 1 h; adding a nano antibacterial powder during the stirring process; then adding an appropriate amount of aqueous additives including a defoaming agent and a leveling agent; and mixing evenly to obtain the environment-friendly aqueous nano transparent heat insulation coating. The invention has the following advantages: improvement of the surface hardness of the UV coating, improvement of aging resistance of the UV coating, prevention from yellowing and no environmental pollution.
