Abstract

The invention discloses a modified fluorosilicone acrylate resin and an antifouling and antibacterial coating. The antibacterial modified fluorosilicone acrylic resin is obtained through an acrylate monomer free radical polymerization reaction and a modification grafting reaction. Then the modified fluorosilicone acrylate resin is uniformly blended with the silane-coated nano-silver particles, a dispersant, a leveling agent, a coupling agent and a filler in a solvent to obtain the coating with antifouling and antibacterial functions. The antifouling and antibacterial coating has excellent adhesion, wear resistance, hydrophobicity, antibacterial property and virus resistance on the surfaces of plastic and glass substrates, and has important value in the aspects of mobile phones, computers, household appliances, glass buildings or products and the like. The invention also discloses a preparation method of the modified fluorosilicone acrylate resin and the antifouling and antibacterial coating.

Description

technical field [0001] The invention belongs to the technical field of functional coatings, and relates to a modified fluorosilicone acrylate resin and an antifouling and antibacterial coating, which can be effectively applied to the protective functional fields of plastics and glass. In addition, the invention also relates to the preparation method of the modified fluorosilicone acrylate resin and the antifouling and antibacterial coating. Background technique [0002] Electronic devices such as mobile phones and computers have become an indispensable tool and assistant for people, and it is very necessary to keep their surfaces clean and healthy. The current novel coronavirus COVID-19 is raging all over the world. Against this background, the demand for antifouling and antibacterial products is even stronger, which is of great significance for protecting people's health and safety and promoting economic development. [0003] Antimicrobial materials play an important role ...
