Wood-plastic composite material and preparation method thereof

Abstract

The invention provides a wood-plastic composite material and a preparation method thereof. The wood-plastic composite material is prepared from the following raw materials: thermoplastic, plant fiber, glass fiber, carbon fiber, an antistatic agent, a flame retardant, a logo printing adhesive agent, calcium carbonate, a heat stabilizer, a plasticizer, a foaming agent, an anti-impact modifier, a lubricant and an anti-ageing agent. Compared with the existing wood-plastic composite material, the logo printing adhesive agent is added to enhance the adhesion of the logo, so that the wood-plastic composite material has printability; the anti-static agent and flame retardant are added to endow the material with antistatic property and flame retardance; and glass fiber and carbon fiber are added to improve the physical and mechanical properties on the promise of ensuring good processing properties of the material.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and in particular relates to a wood-plastic composite material and a preparation method thereof. Background technique [0002] The ammunition packaging box is responsible for the packaging, storage, loading and unloading, transportation and other functions of ammunition. It is required to have high strength, not easy to deform, excellent drop resistance, permanent marking, anti-static, good flame retardant, waterproof, moisture-proof, mildew-proof, Anti-insect, easy to open, light weight and other functions. [0003] Traditional ammunition packaging boxes mainly include wooden boxes and plastic boxes, but wooden boxes have the following disadvantages: easy to absorb water and not moisture-proof, easy to mold, easy to catch fire, easy to be eaten by insects, short storage time, poor corrosion resistance, especially The poor moisture resistance of the box during field or sea transporta...

Problems solved by technology

[0003] Traditional ammunition packaging boxes mainly include wooden boxes and plastic boxes, but wooden boxes have the following disadvantages: easy to absorb water and not moisture-proof, easy to mold, easy to catch fire, easy to be eaten by insects, short storage time, poor corrosion resistance, especially The poor moisture resistance of the box during field or sea transportation will greatly shorten the shelf life of ammunition, especially for high-tech precision guided shells, which require a storage environment with relatively constant humidity and atmosphere. In addition, a large number of wooden boxes are used. The consumption is large, which is not conducive to the sustainable development of the environment

However, the existing wood-plastic composite materials are mainly used in wood-plastic pallets and some other civilian products made of wood-plastic materials. Application requirements for packaging materials
