Wood plastic composite material with anti-bacterial function and preparation method

Abstract

The invention relates to a wood plastic composite material with an anti-bacterial function. The wood plastic composite material is characterized in that raw materials for preparing the wood plastic composite material comprise the following components in parts by weight: 15-40 parts of wheat and rice straw, 1-15 parts of sweet wormwood and 1-3 parts of sweet wormwood extract. The wood plastic composite material has the traditional characteristics of high strength, high elasticity, high toughness, fatigue resistance and the like, has the advantages of being anti-bacterial and mould-proof and enhancing aroma without additionally adding a chemical antibacterial agent and an aroma enhancer, can well meet the needs of places having bacteriostatic requirements, such as hospitals and kindergartens, meanwhile is good for increasing the needs of the market on the raw materials of the sweet wormwood, the wheat and rice straw and the like, and promotes the comprehensive utilization of agricultural straw.

Description

technical field [0001] The invention belongs to the field of wood-plastic materials, and in particular relates to a wood-plastic composite material with antibacterial function and a preparation method thereof. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops, and usually refers to the remaining parts of wheat, rice, corn, potatoes, rapeseed, cotton, sugar cane and other crops after harvesting seeds. More than half of the photosynthetic products of crops exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc. It is a multi-purpose renewable biological resource, and the crude fiber content in straw is as high as 30%. ~40%, and contains lignin etc. [0003] In 2012, the amount of straw that could be collected in my country was 790 million tons, and the comprehensive utilization rate was 74.1%. The remaining 25.9% straw was discarded or burned, which not only wastes reso...

Problems solved by technology

[0003] In 2012, my country's main straw collection capacity was 790 million tons, and the comprehensive utilization rate was 74.1%. The remaining 25.9% straw was discarded or burned, which not only wastes resources, but also causes serious environmental pollution.

However, the application of wood-plastic materials in my country is still in its infancy, and the products are mostly clumsy and simple low-end materials, which lack market competitiveness.
