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.
Description
technical field [0001] The invention relates to a coating, in particular to an environment-friendly water-based nano transparent ultraviolet shielding coating for high-gloss furniture, and also relates to a preparation method of the coating. Background technique [0002] Nanoparticles are favored by countries all over the world because of their novel and unique properties. It has developed rapidly in the past ten years. A series of multi-functional and high-performance nano-composite coatings can be prepared through proper matching of nanomaterials with different functions and a wide variety of polymers. It is widely used in many fields such as construction, wood and automotive coatings. [0003] UV coatings have little environmental pollution, fast curing speed and energy saving. Unlike traditional coatings, which are volatile and slow to cure, UV coatings have become a major substitute for traditional coatings in recent years. Our company through the nanomaterials ...
