Problems solved by technology

[0003] Existing water-based polyurethane coatings are used in furniture, and the surface-drying and hard-drying speeds are slow, which limits the use of coatings. At the same time, the product needs to dry quickly in hot, humid weather, and for low-temperature, low-humidity weather, the quick-drying efficiency Very low, in order to improve the quick-drying efficiency of the product and at the same time take into account the weather resistance of the product, based on this, the present invention further improves the treatment

Abstract

The invention relates to the technical field of furniture coatings, and particularly discloses a quick-drying and high-weather-resistance furniture coating and a preparation method thereof.The coating is prepared from, by weight, 35-45 parts of waterborne polyurethane resin, 15-25 parts of modified carbon nanotubes, 5-10 parts of a graphene synergist, 3-6 parts of a wetting agent, 1-3 parts of a coalescing agent, 1-2 parts of a dispersing agent and 40-50 parts of deionized water. According to the furniture coating, the waterborne polyurethane resin serves as a base material, the modified carbon nanotubes and the graphene synergist are added to enhance the quick-drying and weather resistance of a product, the furniture coating prepared through cooperation of the wetting agent, the dispersing agent and the coalescing agent has excellent performance, the modified carbon nanotubes are added to enhance the quick-drying effect of the product, and the graphene synergist is added to enhance the weather resistance of the product. By adding the graphene synergist, the effect of assisting in synergism is achieved, the weather resistance of the product is enhanced while the quick-drying performance is enhanced, and the performance of bi-directionally coordinating the product is achieved.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a furniture coating with fast drying and high weather resistance and a preparation method. Background technique [0002] Water-based paints include three types: water-soluble paints, water-dilutable paints, and water-dispersible paints (latex paints). Water-soluble coatings use water-soluble resins as film-forming materials, represented by polyvinyl alcohol and its various modifications, in addition to water-soluble alkyd resins, water-soluble epoxy resins, and inorganic polymer water-based resins; Any paint that uses water as a solvent or as a dispersion medium can be called water-based paint. [0003] The existing water-based polyurethane coatings are used in furniture, and the surface drying and actual drying speed are slow, which limits the use of coatings. At the same time, the products need to dry quickly in hot and humid weather, while for low temperature and low humidit...
