Abstract

The invention relates to a preparation method of an antibacterial and mildew-proof luminous decorative coating, and belongs to the technical field of coatings. The invention adopts a chemical reduction method, takes sodium borohydride as a reducing agent and chitosan as a stabilizer to prepare a chitosan nanometer silver solution, wherein nanometer silver can bind to phosphides and sulfides on a bacterial cell membrane; nanometer silver entering the cell membrane can react with sulfides or phosphides of protein and DNA in the cell, block the function of enzymes and replication and transcription of DNA in the cell. A large amount of hydroxyl and amino groups exist in the molecular chain of chitosan and can interact with nanometer silver, stabilize nanometer silver nanoparticles and improvethe antibacterial property. A silane coupling agent is adopted to modify the surface of the silver-loaded chitosan, which has good affinity. The invention combines the antibacterial performance of nano titanium dioxide and silver-loaded chitosan, and the antibacterial and mildew inhibitor has photocatalytic activity under daily illumination conditions, so that the prepared luminous decorative coating has good antibacterial and mildew-proof effect and photocatalytic activity.

Description

technical field [0001] The invention relates to a preparation method of an antibacterial and mildew-proof luminous decorative coating, which belongs to the technical field of coatings. Background technique [0002] Today's world pays great attention to energy saving and environmental protection. Due to the limited mining of natural wood and the increasing demand for decorative materials, wood-grain melamine-impregnated film paper and boards (particle board, MDF) are used in architectural decoration, furniture and other industries. , multi-layer board and medium fiber board), the steel plate is pressed and pasted into a veneer board by a hot press. The Polaboard made of traditional Polaroid paper is printed with oil-based ink, which will leave solvent residues, and the product has a peculiar smell, which is harmful to health. Moreover, the surface hardness of the traditional Polaroid board is not enough, the hand feeling is poor, it is not resistant to corrosion, and the pat...
