Wood-plastic composite artificial board's basic structure is timber and waste or used plastics.Simultaneously, be molten type adhesive with waste or used plastics.Waste or used plastics as the basic principle of molten type adhesive is: this material is the solution state through heating under certain conditions, has certain fluidity, adherence.Under the certain pressure effect, solution is entered in the pit of timber, simultaneously under the comprehensive function of various adhesions such as other physics, chemistry, electronics, cooling, curing, moulding.
In wood-plastic composite artificial board's raw material, timber can be wood chip, wood shavings, also can be other wood fibre, waste or used plastics can be independent kind (new is better), also can be (as the waste or used plastics woven bag that reclaims, outer fiber is PP, and multiple film is PE) of mixing by a certain percentage; Promptly can be film, grain, also can be various fibers made of plastic, (as remaining waste and old fibre of the bag weaved processing of plastics etc.).Work in-process can also require to add necessary auxiliary agent according to reality.
The primary condition of structure of the present invention is: temperature 100-185 ℃; Pressure 2.0-10.0MPa; Time 2-20 minute; The moisture of wood raw material is 8-12%; Material is Qu Liu, linden, birch.Wherein temperature can once add to temperature requiredly, also can first preheating then add to required maximum temperature, but the pressure one-time-reach-place can be pressurizeed progressively also and be put in place.
Wood-plastic composite artificial board's structure of invention, with following basic technology processing,
As shown in the figure.
Now lift the narration of wood-plastic composite plywood test examples:
After the drying of learning from else's experience, moisture content is that 10.5%(annotates (1)), thickness is totally three of 1 millimeter birch sheets 250 * 250, presses ground floor and the 3rd layer of rift grain (or band) second layer band (or rift grain) order and places.Between ground floor and the second layer and the second layer and the 3rd layer, each 5 gram of the waste and old PE film of placement airing after cleaning are evenly balanced, putting into after the alignment through preheating is that 180 ± 5 ℃ OB-25T controls vulcanizing press automatically and earlier pressure transferred to 2.5MPa and gave heat 5 minutes, again pressure is transferred to 5MPa, heated 5 minutes, about 1 minute, pressure is reduced to 0 then, to control vulcanizing press automatically again opens, cooled off 2 minutes, the wood-plastic composite plywood sample is taken off, put cooling typing in 30 minutes in the room temperature.
To mould bonding strength, the moisture content index of the wood-plastic composite plywood sample of structure with the wood of above-mentioned test system, measure with standard test method, the results are shown in Table one.
Table one:
| Interventions Requested | The standard code of method of inspection foundation | Glued board standard value (annotating (2)) | The wood-plastic composite plywood measured value | Measurement unit |
| Bonding strength | GB739－75 | ≥1.37 | 1.96 | MPa |
| Moisture content | GB739－75 | ＜3.0 | 2.8 | % |
From table one test result as can be seen: the inherent quality of wood-plastic composite plywood has surpassed predetermined items and standard figures in GB738-75 " broad-leaved wood glued board " national standard.
According to the characteristics that have waste or used plastics in the wood-plastic clad plate, carry out low temperature resistant bonding strength and heat-resisting gummed strength test again.With testing result and former wood-plastic clad plate bonding strength as a result than seeing Table two.
Table two:
| Interventions Requested | Measurement unit | Former gummed intensity (annotating (3)) | Measured value | Absolute deviation | Remarks |
| Low temperature resistant bonding strength | MPa | 1.96 | 2.10 | +0.14 | (annotating (4)) |
| Heat-resisting bonding strength | MPa | 1.96 | 1.90 | -0.06 | (annotating (5)) |
The bonding strength result of test does not have marked difference as can be seen from table two.
The wood-plastic composite artificial board compares with broad leaf tree material glued board, and main advantage is:
1, will add urea aldehyde glue with timber, structure changes the new structure of wood plastic sectional that adds waste or used plastics with timber into. By selecting the waste or used plastics of unlike material, add different auxiliary agents, the scope of application that can widen wood-based plate makes it have special performance. Such as water-fast property, oil resistivity, acid and alkali-resistance, anti-fire-retardant etc.
2, on the basis of new structure, waste or used plastics has also played the effect of adhesive.
3, owing to need not original solvent type adhesive (such as Lauxite glue) reduce the volatile materials such as free aldehyde to the public hazards of the chronic poisoning of human body and contaminated environment; Reduce original solvent type adhesive at storing, the unsafe factor during use.
4, price is cheap. With 2,600 yuan/tons of Lauxite glue market prices, the individual layer use amount is 120g/ square metre, closes 0.312 yuan of RMB now. With 4,000 yuan/tons of waste or used plastics market prices, the individual layer use amount is 80 g/ms, closes 0.32 yuan of RMB. Such as the residue waste silk with processing PP Polywoven Bag, cost only has 0.29 yuan (3600 yuan/tons) if directly use the recovery waste PP woven bag price of after cleaning (dry-cleaning, wet washing) to reduce.
5, reheat use, namely glue together again. Do not glue together such as wood-plastic composite artificial board behind the cooling curing, can also reheat and glue together.
6, the application on wood-based panel industry also is a kind of new trial as the meltbility bonding agent to utilize waste or used plastics such as PE, PP.
The wood-plastic composite artificial board utilizes useless moulding to do molten type adhesive, present petrochemical industry industrial development is rapid in China, plastic processing industry is more and more flourishing, the quantity of waste or used plastics increases year by year with national timber forest and faces exhaustion, will will hold out broad prospects under the ever-increasing situation with the demand of moulding Dai Mu and sheet material.Can make the forest products retrofit of China increase a series of new kinds, can make existing wood-based panel industry use solvent type adhesive to change to using waste or used plastics to do molten type adhesive merely simultaneously, the environment that also will improve simultaneously forestry products processing industry workman work plays positive, a breakthrough effect.
