Description
Technical Field
The invention belongs to the technical field of wood-plastic composite materials, and particularly relates to a preparation method of a full-biodegradable wood-plastic composite light high-strength plate.
Background
With the increase of population and the rapid development of economy, people have more and more demand on wood and have higher and higher requirements on wood quality. Excessive tree felling and waste of leftover materials aggravate ecological environment damage and resource waste. Wood-plastic composites (WPC) are novel composite materials which are flourishing in recent years at home and abroad, and are green, environment-friendly and environment-friendly novel materials which are produced by using biomass fillers (including Wood flour, rice hulls, bamboo powder, straws and the like) and thermoplastic plastics (including polyethylene, polypropylene, polyvinyl chloride and the like) as main raw materials through processing technologies such as extrusion, mould pressing, injection molding and the like. The wood-plastic composite material can effectively relieve the contradiction between the shortage of wood supply and the increasing social demand, has very important significance for solving the problems of low comprehensive utilization rate of waste biomass materials, ecological environment damage caused by excessive felling and the like, and becomes one of the research hotspots in the field of wood and plastic processing application at present.
The wood-plastic composite material is based on thermoplastic polymers and biomass fillers, has the characteristics of good processing performance, strength performance, adjustability and the like, and is mainly used in industries of building materials, furniture, logistics packaging and the like. However, the wood-plastic composite material is generally prepared by heating, melting and mixing the polymer and the biomass filler and then molding, on one hand, melting and plasticizing need to consume more energy, and on the other hand, the prepared wood-plastic composite material still contains plastic which cannot be biodegraded, and still causes environmental pollution. Therefore, the fully biodegradable wood-plastic composite light high-strength material with excellent performance and strength is obtained by a method with simple research process, energy conservation and environmental friendliness, and has long-term significance for improving the growing environmental problems and improving the supply and demand tension relation of material industry application.
Disclosure of Invention
In order to overcome the defects of the prior art and better solve the problems of low comprehensive utilization rate of waste biomass materials, high energy consumption in the preparation process of the traditional wood-plastic composite, complex process route and incomplete degradation of the wood-plastic composite, the invention provides the preparation method of the fully biodegradable wood-plastic composite light high-strength material, which has the advantages of simple process, energy conservation, environmental friendliness and excellent performance.
In order to achieve the technical purpose, the invention adopts the following technical scheme:
a preparation method of a full-biodegradable wood-plastic composite light high-strength material comprises the following steps:
(1) Extracting the waste wood biomass powder by absolute ethyl alcohol for dewaxing pretreatment, and drying for later use;
(2) Fully infiltrating an organic solvent and the waste wood biomass powder after pretreatment and drying, adding a biomass-based high polymer material, and stirring until the mixture is fully and uniformly mixed to obtain a mixture;
(3) And (3) carrying out compression molding on the mixture, demolding and drying to obtain the fully biodegradable wood-plastic composite light high-strength material.
Further, in the step (1), the waste woody biomass is selected from any one or a combination of two or more of corn stalks, straws, bamboos, reeds, bagasse and wood powder, and the particle size of the powder is less than 60 meshes.
Further, in the step (2), the waste woody biomass powder, the organic solvent and the biomass-based polymer material are calculated according to the following parts by mass:
10 parts by mass of waste wood biomass powder;
15-30 parts by mass of an organic solvent;
8-15 parts of biomass-based high polymer material.
Further, in the step (2), the organic solvent is at least one selected from tetrahydrofuran, chloroform and acetone.
Further, in the step (2), the biomass-based polymer material is at least one selected from polylactic acid and cellulose acetate, and the particle size is less than 150 μm.
Further, in the step (3), the compression molding conditions are as follows: the pressure is 10-20MPa, and the holding time is 60-90s.
Further, in the step (3), the drying process is as follows: drying in the air at 20-40 deg.C and air relative humidity less than 60% for 4-8 hr, and oven drying at 80-100 deg.C for 4-8 hr.
According to the invention, the waste wood biomass powder is fully infiltrated by the organic solvent, and in the process of contacting with the biodegradable biomass-based high polymer material, the molecular chain of the high polymer material is induced to diffuse to the surface and pore structure of the waste wood biomass powder, so that the interface acting force of the waste wood biomass powder and the high polymer material is effectively increased, and the dispersed waste wood biomass powder is further connected by the high polymer material, thereby realizing the preparation of the fully biodegradable wood-plastic composite light high-strength material.
The invention has the following advantages and effects:
(1) Compared with the traditional hot-melting hot-pressing method technical route of firstly melting and compounding, and then adopting the molding processing modes of hot pressing, extrusion, injection and the like, the method only simply stirs and mixes the waste wood biomass powder and the biomass-based high polymer material under the action of the organic solvent, and then molds and dries to obtain the fully biodegradable wood-plastic composite light high-strength material, and has the advantages of simple process, low energy consumption, excellent product performance, 10-26MPa of tensile strength of the product and 150-300MPa of bending strength.
(2) The biomass-based polymer material and the waste wood biomass powder which are used as raw materials are both derived from biomass, so that the biodegradable wood-plastic composite material has the advantage of biodegradability, and compared with the wood-plastic material prepared by compounding traditional petroleum-based plastics and wood powder, the fully biodegradable wood-plastic composite light-weight high-strength material prepared by the method can be completely degraded without causing pollution to the environment.
