Description
Technical field
The present invention relates to the preparation of Wood-plastic material, be specifically related to preparation method and the system of a kind of degradable anti-soil Wood-plastic material
Product.
Background technology
At present, Wood-plastic material technology has had certain Maturity, have also been obtained and is widely applied, daily life photograph, example
Such as floor, balustrade, transom, the cupboard board of fretting map, wave plate, and it also has certain application in terms of furniture.
But furniture is big part product, it is desirable to Wood-plastic material has higher mechanical property.Current Wood-plastic material is by adding glass fibers
Dimension, reinforcing agent etc., although also make mechanical property have certain improvement, but it is still difficult to meet demand.Because it is used for house
Tool often also needs to when manufacturing use with timber collocation, and outer power is pressurizeed or gluedd joint timber and wood to be moulded by force and combines,
To reach good Physical and mechanical properties, holding capacity is big, is unlikely to deform, and service life is long, and the mechanical property moulded such as fruit tree reaches not
To requiring, the total quality of furniture will be affected.It addition, current Wood-plastic material environmental-protecting performance also needs to be optimized further.Finally,
Current Wood-plastic material, in hydrophobic oleophobic performance, substantially has no to improve, and the defect of hydrophobic oleophobic performance difference is for furniture
Being fatal for product, water mark, oil stain, stain etc. adhere on furniture, and the first impact is attractive in appearance, and second easily attracts parasitism
Worm, causes damaging by worms, long fungus, and the 3rd easily degenerates furniture, causes the lifetime of furniture.
Meanwhile, along with furniture item is aging, being continuously increased of discarded amount, make that Wood-plastic material possesses reasonable time length can
Degradation property, also can be one of requirement to Wood-plastic material with natural degradation after the furnature construction part being made from goes out of use.
Summary of the invention
For the above-mentioned deficiency of prior art, it is an object of the invention to, it is provided that a kind of degradable anti-soil Wood-plastic material
Preparation method and goods, it has excellent mechanical property, green environmental protection degradable, and has good anti-pollution characteristic, special
It is not applicable to the manufacturing of Wood plastic furniture structural member.
The present invention be the technical scheme is that for achieving the above object
The preparation method of a kind of degradable anti-soil Wood-plastic material, it is characterised in that it comprises the steps:
1) component of following weight ratio (parts by weight) is prepared:
Wherein, described wood powder be wood powder, powder of straw, kind shell powder more than one, its moisture control is within 1%.
Described filler be calcium carbonate, Pulvis Talci, wollastonite, kaolinic more than one, its moisture control is within 1%.Described idol
Connection agent is maleic anhydride grafted polyethylene or maleic anhydride inoculated polypropylene.Described anti-staining agent is fluorosilicone, poly-17 fluorine certain herbaceous plants with big flowers
Methyl siloxane, poly-nine fluorine hexyl siloxanes, poly-methyl trifluoro propyl siloxanes, one of PDMS, PTFE.Described PA-02 moistens
The compatible coupling agent of sliding dispersion is to be grafted wax with amide-type complex and maleic anhydride, is composited by corresponding proportion；Specifically, institute
Stating PA-02 lubrication and disperse in compatible coupling agent, amide complex, maleic anhydride grafting wax, the weight ratio of stearate are 50: 30
: 4, it should be noted that, PA-02 lubrication disperses compatible coupling agent to be the most firsthand product.Described Nano-meter SiO_22Powder is
Nano level silicon dioxide granule.
2) by PP/PE powder, 150-200 mesh wood powder, modified starch, glass fibre, 900-1100 mesh filler, Nano-meter SiO_22Powder
Height mixes 100-120 DEG C, after being sufficiently mixed, adds PA-02 lubrication and disperses compatible coupling agent, toughness reinforcing compatible coupling agent, anti-staining agent to mix
To 120-140 DEG C, after being sufficiently mixed, pelletize after being cooled to 30-50 DEG C, form degradable anti-soil Wood-plastic material.Need
Bright, the time of batch mixing, pressure, can being adjusted according to actual needs, being sufficiently mixed as long as meeting.Need explanation
Being that all additives preferably use powder, if powder cannot be used, other shapes or form nor affect on, but must
Must keep during batch mixing, the moisture content of material below 1%, preferably 0-0.5%.Whole process, by high mixer batch mixing, mixed
After complete material unloads powder, pelletized by granulator.
Described granulation comprises the steps: to use granulator to pelletize in mixed material, and wherein die head is to the temperature of blanking
Degree sets as follows: 160～170 DEG C, 160～170 DEG C, 165～175 DEG C, 175～185 DEG C, 190～200 DEG C, 200～220 DEG C.
It also comprises the steps: 3) by drying process, make the micelle surface moisture content prepared be less than 1.5%, inside
Moisture content is less than 1%.It is dried and uses the mode dried to carry out, make the micelle surface moisture content prepared be less than 1.5%, inner aqueous
Rate is easy for the injection mo(u)lding in later stage less than 1%, because one of key factor that moisture content is impact wood to be moulded.The height of water content
It is to affect plastics particularly wood to mould the natural enemy of production stability and quality of item, as affected the deformation of goods, the weatherability of goods
With other physical properties.
A kind of degradable anti-soil Wood-plastic material prepared by described method, it is as preparing the product structures such as furniture further
The raw material of part.
It is an advantage of the current invention that: give up with crops such as wood flour, bamboo bits, rice husk, wheat straw, soybean cover, Pericarppium arachidis hypogaeae, bagasse
The natural wooden fiber abandoned is processed as main material, and application plastic material is filling-modified, forms degradable anti-soil Wood-plastic material, and it is
Reversibility recycles high-quality for wood section, has good Physical and mechanical properties, and holding capacity is big, is unlikely to deform, service life
Long, there is good resistance to water, do not damaged by worms, the longest fungus, acid and alkali-resistance, anticorrosive, and also nontoxic, pollution-free, radiationless, can
Reclaiming, meets environmental requirement.Wherein, strengthen its mechanical property by the ratio of glass fibre and filler, by plastics,
Modified starch, the rational proportion of wood powder make it possess degradable environmental-protecting performance under reasonable time length, finally by nanometer
Silicon dioxide and the anti-staining agent component of level regulate its antifouling property, are allowed to molding rear surface and have certain " lotus leaf effect ",
Reach the antifouling effect of hydrophobic oleophobic, be suitable for the manufacture of all kinds of furnature construction part.
