Problems solved by technology

Among them, the rock wool board is mainly made of basalt, which is processed into artificial inorganic fibers through high-temperature melting, and at the same time, a certain proportion of adhesive is evenly added to bake it into a large board. Environmental friendly
EPS board is made of polystyrene resin as raw material plus other raw and auxiliary materials and polymers. It is a rigid foam plastic board manufactured by heating and mixing while injecting a catalyst, and then extrusion molding. The EPS board of this structure has extremely Low water absorption, but not high enough str

Abstract

The invention belongs to the technical field of composite boards, and particularly relates to an antibacterial composite board and a preparation method thereof. The antibacterial board is composed of a core layer, a surface layer and an antibacterial coating, wherein the core layer is composed of chopped basalt fibers, plant fiber powder, glass fibers, nano cellulose and polytetrafluoroethylene short fibers; the antibacterial coating is prepared from carboxymethyl chitosan, nano silver-loaded zirconium silicate, diethylene glycol butyl ether, allyl isothiocyanate, N-substituted alkyl isoquinoline quaternary ammonium salt, sodium fluoride, citral, cetylpyridinium chloride, tributyl citrate, tributyl phosphate, 1-hydroxyethylidene-1,1-diphosphonic acid and dimethyl methylphosphonate. According to the antibacterial composite board disclosed by the invention, the core layer is treated by adopting the antibacterial liquid, so that the core layer has good antibacterial, bactericidal and corrosion-resistant properties, and the antibacterial coating is arranged outside the skin layer, so that the overall antibacterial, bactericidal and corrosion-resistant functions of the board are ensured, the service lifetime of the board is prolonged, and the board has antibacterial durability.

Description

technical field [0001] The invention belongs to the technical field of composite boards, and in particular relates to an antibacterial composite board and a preparation method thereof. Background technique [0002] The antibacterial board is to add a certain amount of antibacterial agent to the board and process it into an antibacterial board. The antibacterial board can inhibit the reproduction of bacteria on the surface of the board, and then achieve the purpose of long-term hygiene and safety. Antibacterial boards are mainly used in environments with high standards for cleanliness, but the antibacterial effect of current antibacterial boards is poor in durability, and the strength of the boards is low. [0003] At present, the materials for preparing the core layer of antibacterial board mainly include EPS, rock wool, glass wool, flame-retardant paper honeycomb board, polyurethane, etc. Among them, the rock wool board is mainly made of basalt, which is processed into ar...
