Nanometer negative-ion wood plastic and manufacturing method thereof

Abstract

The invention discloses nanometer negative-ion wood plastic. The wood plastic comprises the following components in parts by weight: 30-65 parts of waste plant fibers, 5-15 parts of nanometer negative-ion powder, 15-35 parts of thermoplastic resin, 0.5-1 part of traditional Chinese medicine powder, 2-3 parts of a flame retardant, 5-10 parts of a surface modifier, 3-5 parts of a stabilizer, 1-3 parts of a foaming agent, 0.5-1.5 parts of a coupling agent and 2-3 parts of a plasticizer. The nanometer negative-ion wood plastic provided by the invention has the following beneficial effects: a preparation method is simple and practicable in a flow, convenient in operation control and easy in realization of batch production; the nanometer negative-ion powder achieves the purposes of purifying airand eliminating indoor odor and various harmful gases; the traditional Chinese medicine powder improves the sterilization and antibacterial properties of the wood plastic, and changes the smell of the wood plastic; the waste plant fibers realize utilization of wastes like crop straw, so material energy consumption and cost of wood plastic manufacturing are reduced; and waste plant fiber coarse materials and waste plant fiber fine materials are distributed in the wood plastic in a staggered manner, so the tensile strength of the wood plastic is improved, and the wood plastic has the advantagesof good tensile resistance, antibacterial and bactericidal performances and purification performance.

Description

Technical field: [0001] The invention belongs to the technical field of wood-plastic, and in particular relates to a nano-anion wood-plastic and a manufacturing method thereof. Background technique: [0002] Wood-plastic, that is, wood-plastic composite material, 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 instead of the usual resin adhesive, with more than 35% -70% of the 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-plas...

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of nano-anion wood-plastic and its manufacturing method in order to solve the above problems. Sterilization layer, formaldehyde adsorption layer, etc. to achieve the purpose of increasing the performance of wood-plastic, not only increases the process, energy consumption and cost of wood-plastic manufacturing, but also has the disadvantage that the performance of wood-plastic decreases with the increase of the use time
