Abstract
The invention discloses a preparation method of a wood-plastic compound material with improved strength. The wood-plastic compound material with improved strength comprises the following used raw materials by weight percent: 40-70% of plant fiber, 1-3% of reinforced fiber, 4-6% of lubricant and the balance of plastic. The preparation method comprises the following steps: fully mixing the raw materials through melt blending; and carrying out extrusion molding to obtain the wood-plastic compound material. In the technical scheme of the invention, the mechanical property of the whole wood-plastic compound material is enhanced by using the reinforced fiber, and the binding strength of the phase interface between wood powder and plastic is also improved. Simultaneously, specific additives are selected and used. For example, a coupling agent generates strong interface binding between the surfaces of wood powder and the plastic and can reduce water absorption property of the wood powder and improve the compatability and dispersibility between the wood powder and the plastic, therefore the mechanical property of the compound material is greatly improved; in addition, the flowability of a melt and the surface quality of an extrued product are improved by adding the lubricant, thereby obtaining the wood-plastic compound material with good mechanical property and excellent surface quality.
Description
Technical field
The present invention relates to a kind of wood plastic composite, specifically, that relate to is a kind of preparation method who improves wood plastic composite intensity.
Background technology
In recent years, because becoming increasingly conspicuous of global energy and environmental problem adopts the wood plastic composite of the alternative synthon enhancing of the abundant natural plant fibre of nature resin to be subjected to people's attention gradually.Wood plastic composite combines the advantage of plastics and timber, have long service life, attractive in appearance, cost is low, insect protected, anticorrosion, antiskid, can spray, than the hardness height of pure plastic prod, the same with timber have advantage such as can process, bonding and fixing, and can be recycled.Therefore, the building, naval vessel, fence, furniture, automotive material etc. that are widely used in door and window, floor, wall.
The preparation method of existing wood plastic composite generally has: extrusion moulding, injection molding and hot-forming, extrusion moulding can be divided into single stage method and multistep processes.Single stage method is that compounding, devolatilization and the goods of wood plastic composite are extruded in an equipment or one group of equipment and finished continuously.Multistep processes is that compounding, devolatilization and the goods of wood plastic composite are extruded in distinct device and finished, and wood is moulded pellet in the middle of can earlier the starting material compounding being made, and then extrudes and be processed into goods.When adopting single stage method, because of being arranged, the bubble mechanical property reduces significantly as if devolatilization, the not good product that will make of dehydration; Simultaneously, it requires the structure of goods can not be too complicated.So single stage method is often because the wood powder water content is high and the article construction complexity is restricted in the actual course of processing.It is multistep processes that the major part that is adopted is produced in industrialization at present.Because the addition of general wood powder is than higher, it is poor to deposit bigger interfacial energy in the wood plastic composite preparation process between wetting ability vegetable fibre and the hydrophobic polymer, both interfaces are difficult to fully merge, and the vegetable fibre surface exists a large amount of oh groups and easily forms hydrogen bond and cause assembling, thereby vegetable fibre can not be uniformly dispersed in polymkeric substance, and the coacervate of these vegetable fibres easily causes stress concentration under the effect of external force, make the physical and mechanical property of goods descend significantly, have influence on its widespread use.
Such as, the Chinese patent name is called: the sheet material of wood plastic composite and preparation method thereof, wood plastic composite and sheet preparation method, application number: 02157950.4, the applying date: 2002-12-23, publication number is: 1482166, this invention provides a kind of wood plastic composite: " this wood plastic composite is meant by raw materials such as thermoplastic resin, wood powder, auxiliary agent phase solvent, properties-correcting agent and mixes by weight, with this wood plastic composite.After the forcing machine granulation again through extruder for shaping or directly extrude and be expressed on the rolling press by a sheet machine head port mould through the forcing machine fusion plastification, be pressed into plate, sheet material section bar, each heat is laminated with a layer dielectric or fabric in the material top and bottom, or two-sided each again heat be laminated with one deck aluminium foil (band) layer, cut into finished product through cooling off cutting edge.”
And for example, Chinese patent: utilize straw and waste or used plastics to make the method and the material thereof of wood plastic composite, application number: 200710180007.6, the applying date: 2007-10-24, publication number is: 101417459, this invention relates to a kind of method and material thereof that utilizes straw and waste or used plastics to make wood plastic composite: " materials such as polyester and plant lignocellulosic material such as wood chip, bamboo powder, rice husk, straw stalk are mixed by a certain percentage; and add special auxiliary agent, make the complex building section bar through technologies such as high temperature, extruding, moulding.”
Though above-mentioned patent application can both solve certain problem, but still do not solve in the wood plastic composite preparation process the low problem of interface bond strength between the wetting ability vegetable fibre and hydrophobic polymer, the wood plastic composite intensity for preparing is low.
Summary of the invention
The objective of the invention is to solve above-mentioned deficiency of the prior art, a kind of preparation method who improves wood plastic composite intensity is provided, by to measures such as preparation proportion of raw materials optimizations, the wood plastic composite intensity of preparation is improved, especially phase interface bonding strength improves between wood powder and plastics, thereby improves mechanical property.
For realizing above-mentioned purpose, the preparation method of raising wood plastic composite intensity of the present invention, the raw material weight proportioning that it adopts is:
