Abstract

A related flame-retardant antibacterial wood plastic material is composed of the following substances in parts by mass: 6-10 parts of PVC resin, 15-30 parts of polypropylene reworked material, 20-60 parts of wood powder, 8-20 parts of calcium powder, 8-16 parts of sodium polyacrylate, 10-25 parts of polytetrafluoroethylene fiber, 8-10 parts of pentamethyldiethylenetriamine, 4-10 parts of ethylene propylene diene monomer rubber, 12-20 parts of nanometer titanium dioxide, 0.5-1 part of silver carbonate, 0.1-0.5 part of artificial mica, 5-15 parts of montmorillonite, and 1-3 parts of vinyltriethoxysilane. The flame-retardant antibacterial wood plastic material is simple in preparation process and low in production cost, gaps are eliminated by utilizing the principle of thermal expansion and contraction, and also stress is relieved, so that cracks caused by stress concentration is avoided. The flame-retardant antibacterial wood plastic material is effectively improved in surface antibacterial performance and possesses relatively good flame retardation performance.

Description

technical field [0001] The invention relates to the technical field of wood-plastic materials, in particular to a flame-retardant and antibacterial wood-plastic material and a preparation method thereof. Background technique [0002] Wood-plastic, that is, wood-plastic composite materials, refers to the use of polyethylene, polypropylene and polyvinyl chloride, etc., instead of the usual resin glue [0003] Adhesive, mixed with more than 35%-70% of waste plant fibers such as wood flour, rice husk, straw, etc. , mainly used in building materials, furniture, logistics packaging and other industries, the board that is formed by hot extrusion after mixing plastic and wood powder in a certain proportion is called extruded wood-plastic composite board. However, most of the existing wood-plastic products have single functions and cannot provide more functions, so they need to be improved in an appropriate way. Contents of the invention [0004] The object of the present inventi...
