Problems solved by technology

The waste plastics recycled in my country are mainly a mixture of polyethylene, polypropylene and polystyrene. Due to the poor compatibility between various plastic components and the low polarity of the blend, the interface compatibility with wood fiber materials is poor. , the mechanical properties of the prepared wood-plastic composites are poor, especially the low impact resistance, which is not suitable for the production of wood-plastic composite products with high performance requirements

Abstract

The invention relates to the technical field of wood processing preparation, in particular to a high-strength artificial board. The high-strength artificial board comprises, by weight, 30-50 parts ofcedarwood powder, 20-30 parts of sisal hemp residue powder, 20-30 parts of polyethylene, 5-10 parts of urea-formaldehyde resin adhesive, 3-5 parts of flame retardant, 3-6 parts of insect-resist agent,2-4 parts of acrylonitrile, 1-3 parts of magnesium titanate and 0.8-1 part of traditional Chinese powder for removing formaldehyde. The combination of cedarwood and sisal hemp is used as a raw material, not only can sisal hemp residues be effectively utilized, but also the strength of the wooden board can be ensured, and the compatibility of plastic and plant fibers is enhanced, so that the interaction force of an interface is enhanced, and the mechanical performance of the wood plastic board is improved.

Description

technical field [0001] The invention relates to the technical field of wood processing and preparation, in particular to a high-strength wood-based panel and its manufacturing process. Background technique [0002] Wood-plastic composites (Wood-Plastic Composites, 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, polypropylene and polyvinyl chloride, etc. 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 board formed by hot extrusion after mixing plastic and wood powder in a certain proportion is called extruded wood-plastic composite board. [0003] At present, wood-plastic composite boards are mostly processed from plastic a...
