Problems solved by technology

Wood-plastic packaging materials have been rapidly applied as new packaging materials, but nowadays wood-plastic packaging materials have not yet been reported in terms of aesthetics, antibacterial and antifouling, etc. Products that have been packaged for a long time will suffer if the packaging materials have poor antibacterial and antifouling capabilities. Affect the quality performance of the product, so it is necessary to develop a new type of wood-plastic packaging material

Abstract

The invention discloses a preparation method of an antibacterial stain-resistant wood-plastic packaging material. The preparation method comprises the following steps: mixing wood fibers, polypropylene PP, a titanate coupling agent and ethyl acrylate, performing grinding, then pre-heating to 110-130 DEG C, and performing stirring for a reaction for 10-15 min; adding attapulgite and nano-zirconia, and performing ultrasonic dispersion; after that, adding octamethylcyclotetrasiloxane, performing preheating at 150-200 DEG C, and performing compression molding at 0.5-0.8 MPa; soaking the surface of the molded material in a methanol solution with 10-20% of ethylene glycol dimethacrylate for 5-10 min; taking out the molded material, and placing the molded material in an ultraviolet lamp to be irradiated for 3-6 min; after finish of irradiation, flushing and cleaning the surface of the molded material with a methanol water solution; adding the obtained molded material into a solution with the pH of 3.2-4.5, adding methyl methanesulfonate for a reaction, and performing repeated cleaning with deionized water and methanol; and crushing the dried material into particles, soaking the particles in the 10-15% methanol water solution for ultrasonic treatment, and performing pre-heating and mold pressing to obtain the antibacterial stain-resistant wood-plastic packaging material.

Description

technical field [0001] The invention belongs to the field of wood-plastic packaging materials, in particular to an antibacterial and anti-fouling wood-plastic packaging material and a preparation method thereof. Background technique [0002] Wood-plastic composite (WPC) is a new type of composite material that has been booming at home and abroad in recent years. It refers to the use of polyethylene (PE), polypropylene (PP) and polyvinyl chloride (PVC) to replace the usual resin adhesive, and more than More than 50% of wood flour, rice husk, straw and other waste plant fibers are mixed into new wood materials, and then processed by extrusion, molding, injection molding and other plastic processing techniques to produce boards or profiles. Mainly used in building materials, furniture, logistics packaging and other industries. The plastic and wood powder are mixed in a certain proportion and then extruded to form a board, which is called an extruded wood-plastic composite boar...
