Abstract

The invention discloses light-resistant graphene UV ink and a preparation method thereof. The light-resistant graphene UV ink comprises light-resistant graphene UV ink; and the light-resistant graphene UV ink is prepared from polyurethane acrylic resin, photocatalytic modified graphene, pigment, a photoinitiator, a dispersing agent, an auxiliary and filler. The specific preparation process comprises the following steps: weighing a certain amount of Bi(NO3)3.5H2O, dissolving the Bi(NO3)3.5H2O in an HNO3 aqueous solution, adding ethylenediamine tetraacetic acid (EDTA) with a certain concentration, meanwhile, weighing a certain amount of NH4VO3, dissolving the NH4VO3 in deionized water, and conducting heating and stirring at 45 DEG C until the solution is clear, so as to obtain a BiVO4 precursor solution; step 2, preparing photocatalytic graphene UV ink, and conducting storing in a dark place; and step 4, filtering the photocatalytic graphene UV printing ink, adding the filtered photocatalytic graphene UV printing ink into an ink fountain, and carrying out PVC film unwinding, intaglio printing (coating), air box drying, UV curing, protective layer coating, air box drying and winding to obtain a finished product. A high-temperature and high-pressure reaction kettle is adopted for preparation, blending and storage are performed under the dark condition, the preparation process is simple, the yield is high, the product validity period is long, and the method is suitable for industrial production.

Description

technical field [0001] The invention relates to a light-resistant graphene UV ink and a preparation method thereof, belonging to the technical field of PVC film printing. Background technique [0002] With the improvement of production technology, polyvinyl chloride (PVC) decorative panels are widely used in the field of architectural decoration due to their advantages such as non-flammability, high strength, weather resistance and low processing cost. Direct printing of PVC film refers to printing patterns and patterns of various colors directly on the surface of PVC film through printing process to achieve imitation wood, imitation marble and other effects. It has the characteristics of simple process and less material consumption, and can be greatly improved Improve the added value of PVC decorative panels. [0003] Inks used for direct printing of PVC films are becoming more and more popular due to their advantages of cold curing, fast curing, low volatility, environmen...
