Water paint containing composite antibacterial nano-fibers and used for wooden crafts and preparation method of water paint

Abstract

The invention discloses water paint containing composite antibacterial nano-fibers and used for wooden crafts. The water paint is based on a waterborne acrylic emulsion, and the composite antibacterial nano-fibers are added into the waterborne acrylic emulsion; and the composite nano-fibers load nanometer zirconium phosphate carrying silver antimicrobial agents on cellulose acetate to improve the dispersibility of a nano-antibacterial agent and further enhance the strength of the nano-fibers; nano-size composite fibers are prepared by utilizing an electrostatic spinning process, so that the performance of a coating can be effectively improved, a uniform and ventilated nano-fiber layer can be formed after the nano-size composite fibers are cured, the coating is endowed with good hand feeling like fabric, the water paint has the efficacy of sterilization, fouling resistance, yellowing resistance, scrub resistance, oil resistance and the like, can effectively protect the wooden crafts and is environment-friendly and safe.

Description

technical field [0001] The invention relates to the technical field of water-based paint, in particular to a water-based paint containing composite antibacterial nanofibers for wooden handicrafts and a preparation method thereof. Background technique [0002] Wooden handicrafts are a kind of handicrafts with unique style and ornamental value, which are made of various kinds of wood by machine or hand. It is more refined and has a longer service life, so there are different requirements for its surface protection. Spraying paint on the surface of wood is a relatively common means of protection. The performance of the paint used on the surface will directly affect the ornamental value and use of handicrafts. Longevity, due to the particularity of handicrafts, the paint used should not only be environmentally friendly and pollution-free, but also have certain moisture permeability and air permeability to ensure that the wood is not too dry and prevents deformation. Although th...

The research in the article "Feasibility of Natural Fiber Micro / Nano Fibrils Modified Furniture Coatings" shows that natural cellulose nanofibrils have greatly improved the basic properties of coatings such as wear resistance, scratch resistance, and flexibility. However, Natural cellulose itself is prone to aging and degradation under the influence of environmental factors, which shortens the service life and affects the protective effect of the coating

[0004] Cellulose acetate is an important type of man-made fiber. It is a chemically modified natural polymer obtained by esterifying the hydroxyl group in the cellulose molecule with acetate. It is suitable as a modifier for water-based coatings. Its unique porous structure can effectively improve the air permeability of the coating. However, the mechanical properties of a single cellulose acetate nanofiber are poor. In order to improve the performance of the coating, further research is required. Technical Improvement
