Abstract

The invention relates to an antibacterial environment-friendly board, particularly an antibacterial decorative board and a preparation method thereof. The antibacterial decorative board comprises, from top to bottom in order, an antibacterial surface layer, a decorative paper line layer, a balance enhancement layer, a substrate layer and a balance layer that are bonded to each other. The preparation method consists of: firstly making a stearic acid salt, calcium carbonate, carbon fiber and glass fiber, phenolic resin, unsaturated polyester resin, polyvinyl fluoride, copper naphthenate, cobalt iso-octoate, a coupling agent, and an acrylonitrile-butadiene-styrene copolymer into the substrate layer, pasting the balance enhancement layer and the balance layer respectively, performing pressing, then sticking the decorative paper line layer and conducting pressing, applying an antibacterial paint, and performing drying to form the antibacterial surface layer. The invention adopts a multilayer structure to ensure the board strength, the coating also can effectively prevent scratching, the balance enhancement layer and the balance layer improve the tensile properties of the board, and the substrate layer is made of a resin material, is elastic and can absorb the impact of external force, and the construction is convenient and fast.

Description

technical field [0001] The invention relates to an antibacterial and environment-friendly board, in particular to an antibacterial decorative board and a preparation method thereof. It belongs to the technical field of decorative antibacterial materials. Background technique [0002] Antibacterial boards are mainly used for decoration in public places, especially in medical and clean places. At present, the commonly used antibacterial boards on the market are made of density fiber cement boards as the base material and coated with paint on the surface. This kind of antibacterial board has a hard surface, cannot effectively prevent impacts, and is easily scratched and difficult to repair. Moreover, it is difficult to install the cement board, and it needs to be stably fixed on the wall through cement steel nails and other methods. Contents of the invention [0003] Aiming at the above technical problems, the present invention provides an antibacterial board that is resist...
