Description
Technical field：
The present invention relates to plastic-wood material production technical field, more particularly to a kind of aluminium plastic co-extruding preparation technology.
Background technology：
Plastics Packaging Wastes seriously pollute environment, have impact on industrial and agricultural production, compromise human health and dynamic
The existence of plant.World's plastics annual production more than 200,000,000 tons, China plastics packaging materials 2007 more than 10,000,000 tons, this
A little plastic package materials and container are most of into solid waste after disposable.Plastics Packaging Wastes are lightweight,
Volume is big, quantity is more, it is difficult to degrade, and can not arbitrarily incinerate again, railway side, inland waters and cities and towns street is discarded in mostly small
Lane, accumulate over a long period " white pollution " band for having become startling.According to the relevant departments of the investigation 1000 tons of rubbish of Shanghai daily output is understood,
Plastic refuse accounts for 330 tons；12000 tons of rubbish is produced in Beijing daily, and plastic refuse accounts for 360 tons；Guangzhou daily output rubbish is about
6000 tons, plastic garbage accounts for 200 tons.
China's logging residue and producing material residue account for the 40% of Tree biomass, according to " the 11 of State Council approved
The m3/a of forest pathogen 2.5 hundred million are calculated during five ", and China will produce about 1.1 hundred million tons of felling, producing material residue every year.Separately
Outside, industrial wood waste calculates the annual production for also having up to 32,100,000 m3 by the 34.4% of log.At present, although forestry " three surplus things "
Utilization caused the attention of people, but worldwide development level and uneven.The wood of the developing countries such as China
Material comprehensive utilization ratio is only 50%~60%, and the wood comprehensive utilization rate of developed country is up to 80%~90%." three remain for forestry
The development and utilization situation of thing "：Forestry " three surplus things " generally bulk density is low, volume is big, and distribution is loose, is not easy to collect, stores up
Hide and transport, therefore traditional " three surplus things " processing mode mostly to abandon, burn or fill etc. based on plain mode on the spot.Mesh
Before, as people gradually step up to the attention rate of air and water quality, these traditional methods can not continue to continue to use.And pass through wood
The engineering and high performance of (bamboo) plastic material, the modification regeneration of waste plastic and bamboo wood chip resource make full use of, and can solve
Certainly waste or used plastics, the regeneration problem of bamboo wood working industry waste resource.
Current plastic-wood composite floor mainly using plastics, bamboo/wood-fibred as raw material, it be by plastics and bamboo (wood) consider to be worth doing according to
It is similar to 3：What 5 ratio was made.Modeling wood has the Waterproof corrosion of plastics and two kinds of characteristics of texture of timber concurrently so that it turns into one
Plant function admirable and very durable outdoor building materials purposes is extremely wide.Existing modeling wood products performance is still not ideal enough, also exists
The problems such as density of some defects, such as plastic wood sheet, intensity.
The content of the invention：
The technical problems to be solved by the invention are the defect for overcoming prior art, it is further proposed that a kind of aluminium plastic co-extruding
Preparation technology, the technique solves the solid easy ponding of wood-plastic board, problems of crack.
The technical problems to be solved by the invention are realized using following technical scheme.
A kind of aluminium plastic co-extruding preparation technology, it is characterised in that：Aluminium plastic co-extruding is that aluminium alloy is closely complex as one with PE modeling wood
The composite material of body, it is that thickness about 4mm surface is moulded into wood that it, which makes, is compounded in aluminium alloy section surface, reach interior metal with
Outer modeling wood integrally combines；Therefore high accuracy, high intensity and the modeling wood that the simultaneously compatible shape of the section bar has are erosion-resisting excellent
Point；Mainly include batch mixing, granulation, composite co-extruding, cooling and shaping production process；
Granulation process, required raw material components and group component are：
Above each group component sum meets 100%；
Mixing process, by material by formula mixing, by batch mixer high-speed stirred, frictional heat, to the technological temperature of setting
Be discharged into after 110 DEG C~125 DEG C it is cold mixed, to 40 DEG C of technique of setting after discharge；
Granulation process, above-mentioned raw materials are proportionally added into elevating hopper, are heated, mediated in comminutor, bonded
Step, prilling temperature is 180-220 DEG C, and time of the material in comminutor is 15 minutes, finally obtained material grain；
Composite co-extruding process, the particle granulated is added in extruder elevating hopper, heated in an extruder, screw rod
Interior shearing plasticizing, extrusion temperature is 140-220 DEG C, and the time of material in an extruder is 20 minutes, a side in co-extrusion die head
Face is passed through aluminium, and one side plastic-wood embryo co-extrusion is in aluminium material surface；
Cooling and shaping process：The type embryo of coextrusion cools down fixed in stock mould.
Beneficial effect：
A, cost performance are high：Compared with the aluminium alloy extrusions of equal performance, aluminium in the outer wood of the wooden plastic-aluminum co-extrusion section bar of modeling, than same wall
Thick aluminium alloy extrusions price is low；
B, energy-saving and emission-reduction：The wooden plastic-aluminum co-extrusion section bar of modeling combines aluminium alloy and modeling wood together, has saved energy consumption and has subtracted
Carbon emission is lacked；
C, precision are high：As a result of the aluminium alloy extrusions of high-grade degree, the machining accuracy of the wooden aluminium plastic co-extruding of modeling is higher than modeling wood
Section bar, reaches the precision close to aluminium alloy extrusions；
D, intensity are high, the ingenious structure of dovetail groove, and aluminium alloy is combined with the perfect co-extrusion of modeling wood, it is ensured that the wooden plastic-aluminum of modeling is total to
Extrusion section bar integral rigidity；
E, rich color, good appearance：The wooden various colors of outer layer modeling, the more warm breath of timber；
F, service life are long, and normal service life may be up to more than 50 years.
With other product comparative experimental datas.
