Description
Technical field
The invention belongs to field of compound material, and in particular to application of the xylose residue in Wood-plastic material is prepared.
Background technology
Wood plastic composite is using wood-fibred or string as key component, is allowed to by pretreatment and thermoplastic resin
A kind of or new material that other materials are combined.The remaining discarded wood chip amount of China's annual timber processing millions of tons with
On, other natural fibers such as rice chaff etc. reaches up to ten million tons, and waste or used plastics total amount reaches nearly hundred million tons, and wood moulding is effective by these waste and scraps
Ground uses, and produces huge economic and social profit.Compared with timber, same to tropism, weatherability and the dimensionally stable of wood moulding
Property it is good, product be not afraid of moth, not raw fungi, it is not hygroscopic, deformation, good mechanical property is more robust, have it is hard, tough, resistance to
Long, the advantages that wear-resisting, and plus the various additives of application, the various properties of wood plastic composite are imparted again, with plastics
Compare, it is applied to various timber processing modes, and surface is easy to decorate, and can print, paint, spraying, the processing such as overlay film, environmental protection
Performance is good, can produce a variety of colors entirety wood grain product and one color product.
At present, plant wood fibre is the main constituents in wood moulding production, is ground extensively on using species
Study carefully and apply, what is be commonly used has bamboo powder, powdered rice hulls etc., and this also solves the application problem of agricultural wastes, while also protects
Environment.But in the production process of xylose, there is substantial amounts of xylose residue discarded object not used fully every year.Xylose residue
Be corncob, bagasse, bamboo scraps etc. after low-kappa number, extract remaining residue after xylose.With the wooden fibre of other plants
Dimension element is compared, and the avicel cellulose in xylose residue is higher (as shown in table 1) with content of lignin, and this can improve Wood-plastic material
Physical property, mechanical property (such as impact strength, tensile property), while anti-ultraviolet ageing effect also significantly improves.

Xylose residue | 45.34 | 4.23 | 40.09 | 8.67 |
Therefore xylose residue is the very good material of Wood-plastic material, has extensive market application foreground.Application to xylose residue
Investigated, Chinese patent 201610834634 discloses the process that a kind of xylose residue prepares sheet material, by drying, crushes
Xylose residue mixed with phenolic resin glue, then bed board press obtains xylose residue sheet material, but xylose residue sheet material and Wood-plastic material
It is the very big material of two kinds of differences.And the Patents and report using xylose residue production Wood-plastic material are had no at present.This patent
Plant lignocellulose raw material is replaced with xylose residue, wood plastic composite is made using corresponding production technology, xylose residue is entered
Effective utilization is gone.

During being cooled to less than 60 DEG C, because being passed through cold water and rotating speed reduction, the reduction of temperature result in.
In the mixed process, high temperature batch mixing is first carried out so that each component can be sufficiently mixed, and when high temperature, be had
A little materials can be mutually grafted;Low temperature batch mixing is carried out again so that the temperature of material reduces, and otherwise temperature is too high, to material property
It is stable etc. to have an impact
In step (3), the method for Wood-plastic material, which is prepared, to be included direct extrusion molding method and is first granulated extrusion molding again
Method.
Wherein, it is acid stronger because residual acid is more contained by xylose residue, and contain certain silt, therefore can not directly make
With, otherwise screw rod etc. can be caused corrosion etc. destroy.
Xylose residue pretreatment operation comprises the following steps that in step (1):
A. depickling is cleaned:Take xylose residue, add appropriate water to dilute cleaning, ceaselessly stirring and washing remove silt with it is corresponding
Acid;
B. plus alkali neutralizes:Rinsed, washed to neutrality with alkali, and most moisture is removed with dehydration device;Wherein,
Described alkali is the aqueous solution of calcium hydroxide, sodium hydroxide, barium hydroxide, magnesium hydroxide, aluminium hydroxide or iron hydroxide, its
In, the preferably calcium hydroxide aqueous solution.
C. drying and crushing:Dry in drying device, then it is crushed with pulverizer, it is standby.
After being handled using the above method xylose residue, after resulting residual acid is concentrated, can circulate again makes
Preparation for xylose.
Beneficial effect:
Compared with prior art, the present invention has following advantage:
The present invention provides a kind of new method for effective utilize of xylose residue.Due to having been sloughed during xylose production easily
The hemicellulose of water suction, the content of lignin is added, and lignin has good UVResistant effect etc., hence in so that with xylose
Slag increases for the physical property of raw material preparation wood moulding, mechanical property, heat endurance, anti-ultraviolet ageing positive effect;In addition, at this
In inventive method, lignin and modified lignin resin can be further added by addition, further increase wood plastic composite mechanical property,
Anti-aging and UVResistant effect.Also, the remaining residual acid of the processing method of the invention to xylose residue, which can also concentrate, to be reused,
Be advantageous to environmental protection;And the calcium hydroxide added in pre-processing and residual acid reaction generation calcium sulfate, related filling can be replaced
Thing (such as calcium carbonate, calcium sulfate, talcum powder), and the hardness of calcium sulfate is low, is damaged than calcium carbonate, talcum powder etc. to caused by machine
Wound is low, is advantageous to extend the service life of machine.
