Three, preparation technology of the present invention
1. the processing of wood powder.The wood powder of undried directly use can cause that goods bubble, burning, even in the machine barrel implode, because the actual moisture that contains of wood powder, and polymkeric substance such as wood powder and polyvinylchloride does not have bonding force, therefore simply sneaks into the goods that can only obtain being highly brittle in the wood powder, must carry out its modification is handled, its method is under 190-230 ℃ of temperature, remove moisture and the easy decomposition components of part in the wood powder, the wood powder after the thermal treatment also will carry out polymer with following method and coat, and makes it to have lipophilicity.
Method: (a) coupling method:
Thin wood powder is crossed thin wood powder heat treated under 190-230 ℃ temperature that its granularity of 60-100 mesh sieve is 150-250 μ m, this is handled dried wood powder adds in the stirrer and stirs, this moment, temperature was when remaining on 90-100 ℃, added aluminate coupling agent and continued to mix and namely obtain modified wood powder.
(b) surface connects skill and technique:
Thin wood powder is crossed thin wood powder heat treated under 190-230 ℃ of temperature that its granularity of 60-100 mesh sieve is 150-250 μ m, stir in the wood powder adding stirrer with drying then, and with soaker butyl acrylate polymerization starter benzoyl peroxide, the mixture of polymerization promotor xylidine adds in the wood powder that is stirring, flood 2h again, stirring makes it even, heats up then 100-400 ℃ to keep 4h, make the soaker sclerosis in the wood powder, thereby obtain modified wood powder.
2. use bagasse as processing and the surface treatment preparation technology of non-wood fiber:
Method: (a) bagasse is piled up can adopt that nature dries after the spontaneous fermentation, hot-air seasoning and microwave drying, purpose is to remove low molecular weight substance and easily decomposition in the non-wood fiber, dry preferably about 150 ℃ for cane powder, more than the oven dry 3h, cross the 80-120 mesh sieve with pulverizer then, this moment, the main component of cane powder non-wood fiber was Mierocrystalline cellulose and xylogen, wherein also contained a large amount of hydroxyls, has very big polarity, moisture absorption easily; And the thermoplastics majority is nonpolar or low-pole, has hydrophobicity, intermiscibility is relatively poor between the two, interface binding power is very little, so will handle the intermiscibility problem that solves non-wood fiber and return these two kinds of materials of plastic waste to the cane kind non-wood fiber, this kind surface-treated method: be exactly with silane coupling agent and titanate coupling agent or aluminate coupling agent non-wood fiber to be carried out surface treatment and solve two kinds of material intermiscibility problems, the effect of coupling agent is with relevant to wood powder surface coverage degree, and consumption distributes 2% to be advisable for the non-wood fiber powder quality.
(b) blend granulation and extrusion moulding:
The method that is about to non-wood fiber powder and thermoplastics blend granulation and extrusion moulding is that 100g calculating places in the high speed kneader by thermoplastics, then need to add 1. the organic system 7% below or inorganic be that thermo-stabilizer, powder, liquid all can use, can prevent the thermolysis of resin chance like this; 2. the organic system whipping agent below 5% because can emit gas after the heating, is stayed in the plastic cement of gel, forms the foam of open air chamber; 3. the softening agent below 10%; 4. the organic polymer below 15% is processing aid, and purpose is to improve the plastic cement gel; 5. 5% lubricant can reduce the plastics temperature like this, promotes gel, and lubricant all can use with powder or liquid; 6. 7% medical stone nano powder, the purpose release of trace elements, the poisonous and harmful heavy metallic in absorption antagonism air and the water purifies water; 7. 8% strange ice stone is the tourmalinite nano powder, and purpose produces negative ion, promotes health; 8. 6% pigment.
Method for making: above-mentioned each material is formed % by proportion by weight put into respectively and stir the back temperature and can reach in the high speed kneader below 110 ℃; obtain dry and soft shape powder; the mixed powder that is easy to carry; just stop to stir; by the tablets press granulation, the water ratio of the pellet after the granulation will be lower than 3%, then pellet is placed the barrel of single screw extrusion molding machine then; between plasticating temperature 120-200 ℃, condensate temperature is low foaming extrusion molding below 20 ℃.
Non-wood fiber such as bagasse; dried sugar content is below 1%; water ratio is below 10%; can be by aging process except sugar; this can use acetic acid; oxalic acid; the hydrogen peroxide bleaching decolouring; method is: will cross the bagasse and the titanate coupling agent that is made into the aqueous solution of 100 mesh sieves after the drying and crushing; under stirring, spraying evenly mixes; be dried to water ratio then below 10%; evenly mix later at 110 ℃ by the high speed kneader with unclassified stores again; and use the tablets press granulation, the pellet water ratio adds pellet in the barrel to below 3% again; extrude about plasticating temperature to 170 ℃ with single screw extrusion molding machine, and with about 15 ℃ water of condensation cooling forming.Water wave can be used the embossed wheel embossing if desired, and after the goods extrusion moulding, getting the suitable length shearing becomes needed finished product.
Four, preparation process of the present invention
Must to select the low 200 ℃ Plastic Resin of fusing point be carrier to the material of preparation plastic floor brick of the present invention, otherwise in the carbonization of will degrading of forcing machine implants fiber.Generally compo being extruded the methods that adopt more has a step direct extrusion molding and two to go on foot the method for granulation hybrid process in advance.
1. direct extrusion molding of a step is material mixed homogenizing in forcing machine, by the geometrical shape moulding product of mold component.This has higher requirement to forcing machine.The design of forcing machine need have unique compression and low velocity shear to mix ability, fully optimize the feed zone surface-area, make screw rod faster, more even to raw-material heat transfer process, a bigger feed zone need be provided when screw design, be used for bulk material and apply the nature force of compression man-hour adding, its result more effectively " is soaked " for timber.When reducing shearing force, the extruded stock mixing is optimized in the dark screw channel between twin screw and compact crossing perforation crack, and the high moment of torsion place under low screw speed state uses soft low-shearing power fusing and mixes, reduction wood powder rate of decomposition.
2. the method for granulation hybrid process in advance.Stable starting material are primary prerequisites of normally extruding, in order to guarantee the reliable metering to filamentary material, usually be necessary to adopt the two-step approach expressing technique that filamentary material granulation preliminary election is compressed, directly extruding loose fiber with single stage method compares, this Preblend mode can be increased to needed level to powder density, extrude output thereby reach, being easy to circulation is improved, the homogeneity of powder density has guaranteed the consistence of extrusion in addition, this two-step process, in the early stage the preparatory stage, cold and hot mixing granulation can significantly be reduced to 1% with moisture, and wood powder and plastics are mixed fully, plastics can be penetrated in the wood powder fully like this.Compare with single stage method, two-step process can improve the impact property of section bar, can change the impelling strength of wood plastic composite, in addition humidity less than 1% situation under, forcing machine can be extruded according to specified extrusion capacity, if use humidity is greater than 8% wood powder, extrusion capacity will reduce 30-50%.Equally, in the one-step technology, loose wood powder can cause the change of traction difficulties and prescription inevitably, and causes the change of extrusion capacity.And just there is not this problem in the two-step approach treatment process, and the starting material of handling can be without doubt be used for extruding, in addition can and polyvinyl chloride " PVC " resin section bar extrude similarly, when extruding, also needn't adjust and constantly optimize the expressing technique parameter.
