Description
Technical field
The present invention relates to a kind of wood plastic composite and preparation method thereof, relate in particular to turmeric fiber base wood-plastic matrix material and preparation method thereof.
Background technology
Along with development of global economy, on the one hand, the use that various plastics are a large amount of, waste or used plastics rubbish spreads all over the world, and the environment of human living has been caused great pollution; On the other hand, a large amount of forests is cut down, and has caused the destruction of soil erosion and ecotope.How solving white pollution, saving the forest reserves is pendulum big problems in face of people.Wood fibre or vegetable fibre are filled the plastics that reclaim, through custom-built machine extrude, compacting or injection moulding, the goods of making can substitute timber-work, have both solved white pollution problems, have saved the forest reserves again, help the protection of ecotope.Therefore from environmental protection and economic angle, use the meaning and the prospect of wood fibre filling waste or used plastics more considerable.
Publication number provides a kind of by wood powder enhanced compound plastic plate for the Chinese patent application of CN1255427A.Be polypropylene, a small amount of polyethylene and wood powder, paper scrap and hotmelt melt blending are extruded or to be rolled and get.So-called hotmelt is the grafts of polypropylene and polar monomer (join as maleic acid etc.).The recovery plastics are not used in this patent application, and adding wood powder in plastics is in order to improve the intensity of plastic plate.Wherein the acquisition of hotmelt also needs graft process in advance, and preparation method and operating procedure are complicated, the cost height.
Publication number also provides similar a kind of matrix material by wood powder reinforced polypropylene for the Chinese patent application of CN1257890A.Also use polyacrylic grafts as wood powder and polyacrylic coupling agent.Add conventional processing aid in addition, be selected from polyethylene wax, chlorinatedpolyethylene, oxidic polyethylene, its chlorinated polypropylene, the clorafin one or more, to improve the flowability of wood powder.
Publication number provides the blend of a kind of wood fibre and waste or used plastics for the Chinese patent application of CN1204656A.Oligomer polymer overmold wood powder is used in this invention, improves the avidity of wood powder and waste or used plastics.The oligomer polymkeric substance is selected from ethene paraffin or Atactic Polypropelene or chlorinatedpolyethylene.
Publication number provides a kind of wood plastic composite and its production and application for the Chinese patent application of CN151391SA.This matrix material includes components such as reclaiming plastics, wood fibre and resin compatible agent.Wherein the resin compatible agent is made up of the polymkeric substance and the chlorinatedpolyethylene mixing of EVA, vinylformic acid or acrylate, can improve the consistency of plastics and wood fibre, and improve mechanical property; The ratio of weight and number of resin compatible agent and plastics is 2: 100～5: 100, and wood fibre is 100: 100～250: 100 with the ratio of weight and number that reclaims plastics.Prepare by common melt-mixing method in the plastic working by described component.This wood plastic composite is not only improving aspect intensity and the toughness greatly, and its forming process also is greatly improved, and has improved the production efficiency and the application prospect of wood plastic composite greatly.
Because the surface of yellow ginger fiber is through based structures, it is the polarity hydrophilic substance, and plastics are non-hydrophilic substance, both affinity extreme differences, as simply with both blend, its product surface is coarse, mechanical property is very poor, even use toxilic acid to connect the skill material as solubilizing agent, but effect is very poor always, key is the difference that wood is moulded two interface interactions, mould the bonded of interface dissolving between the two problem for solving wood, need add reinforcer to the yellow ginger fiber, its modification, enhancing wood is moulded two interfaces and is effectively dissolved combination, and processing contains the high Wood-plastic composite section bar of wood fibre.
Summary of the invention
For the affinity that solves above-mentioned wood fibre and LDPE and the technical problem of consistency.The purpose of this invention is to provide a kind of reinforcement yellow ginger fiber and substitute wood fibre fully, and the good turmeric fiber base wood-plastic composite material of processing characteristics.And the preparation method of above-mentioned turmeric fiber base wood-plastic matrix material.
To achieve these goals, the present invention has adopted following technical scheme: the turmeric fiber base wood-plastic matrix material is characterized in that: the composition of pressing column weight amount per-cent is formed: melamine resin 3.5%; Yellow ginger fiber 60%; New LDPE (film grade) 32%; Solubilizing agent 2%; Lubricant 2.5%.
To further improvement in the technical proposal be: described lubricant comprises in cured one or both of dimethyl silicone oil, polyester.
To further improvement in the technical proposal be: described solubilizing agent is that toxilic acid is liquor-saturated, vinylformic acid, cinnamic multipolymer.
The preparation method of above-mentioned turmeric fiber base wood-plastic matrix material comprises the steps: (1) with melamine resin and the mixing of yellow ginger fibre high-speed heat, and dehydration obtains modification yellow ginger fiber; (2) with the above-mentioned modification yellow ginger fiber that obtains and new LDPE (film grade), solubilizing agent, mix lubricant, extruder grain; (3) the particle extrusion molding that granulation is obtained, cooling, cutting; (4) the surface galling shaping obtains finished product, and perhaps frosted polishing back is answered film blanching seal and obtained finished product.
To further improvement in the technical proposal be: described high speed heat is mixed employing awl twin screw extruder.
To further improvement in the technical proposal be: the hot blended temperature of described high speed is 180～225 ℃.
Yellow ginger fiber melamine resin of the present invention produces high temperature and disperses under the blade friction of homogenizer and finishes dehydration, intensive treatment, and mixed matchingization, it has strengthened the type condition, has prolonged the type course, has guaranteed the type quality.Its strengthening effect is as follows:
1, neutralization and the Evaporation that utilizes melamine resin to produce in solidification process removed the wood vinegar in the yellow ginger fiber fast, avoided the bubble type to become, and prevented the Wood-plastic composite section bar surface irregularity.
2, strengthen wood and moulded the effect of two interfaces dissolving bonded, made the effect of solubilizing agent more effective, increased substantially the physical and mechanical properties of Wood-plastic composite section bar.
3, improve the thermostability of wood fibre, made it to adapt to various processing of plastic temperature.
4, can control the increase of wood fibre water absorbability and water content effectively, reduce in the extrusion moulding process friction with machinery, die surface.
5, experimental results show that, the wooden basic PE wood plastic sectional composite material of yellow ginger fibre content more than 60% is after adopting above-mentioned enhancements, moulding with the same proportioning wood that does not have intensive treatment is 1/3rd, and the dimensional stability and the coefficient of expansion only are 1/3rd, and other indexs also have notable difference.
Wood-plastic composite environment-friendly building materials of the present invention adopt new and high technology, utilize waste plastic and a large amount of yellow ginger fiber pulvis, by the various hollow materials of the wooden-plastic of fiber strengthening high-temperature mixing and extrusion moulding, are a kind of typical environment-friendly materials.Have sun-proof, waterproof, mothproof, antifreeze, rot-resistant characteristics, woodiness touch is strong, the surface hardness height, and wear resistance is strong, resistance to deterioration is good, and long service life is easy to processing, not containing formaldehyde, is to be suitable for the indoor outer preferred material of decorating, and likeness in form timber is better than the performance of timber again.
