In the limitation of itself, the cost of PLA material is higher, material is easy for deformation, easy occluding device nozzle more than 55 DEG C；
ABS material is more sensitive to temperature and shear rate, and smell is heavy in process, yielding and weatherability is poor；And PVA is water-soluble
Material is mainly used in printing support type material, and consumption is few, and can produce toxic gas during PVA decomposition.And tradition 3D printing is wooden
Material, exist wood powder be easily carbonized blocking printing plug, the shortcomings of product is more crisp.In a word, widely used 3D in the market
Printing consumables has the shortcomings that price height, high energy consumption, complicated harsh, the difficult shaping of processing conditions requirement, easy fracture.
It is, thus, sought for a kind of 3D printing consumptive material, it is not only cheap, green low-carbon environment-friendly, good stability of the dimension,
Intensity is high, have the advantages that in process not plug-hole, not fracture of wire, without buckling deformation, and the product produced have it is preferable
Physical and mechanical properties and weatherability.
The content of the invention
For the problems of above-mentioned prior art, it is an object of the invention to provide a kind of cheap, low-carbon environment-friendly,
It circulation and stress can very recycle, natural wood aromatic odor, size can be produced when the natural friendliness with timber, printing
Stability is good, not plug-hole, non-warpage, processing conditions require low, and product have preferable physical and mechanical properties and acid and alkali-resistance,
The 3D printing consumptive material of weatherability and preparation method thereof such as Anti-moth-eating, ultraviolet-resistent property ability be strong.
To reach above-mentioned purpose, the technical solution adopted in the present invention is：

As preferred technical scheme is invented, compatilizer is that maleic anhydride is grafted PLA compatilizers；Described coupling agent is silicon
One kind in alkane coupling agent；Described lubricant is paraffin, Tissuemat E, ethylene bis stearic acid amide, ethylene-acrylic acid copolymer
The mixture of two or more in thing, stearic acid, zinc stearate；Described toughener is poly- (hexanedioic acid-succinic acid) fourth two
Alcohol copolyesters.
Present invention also offers a kind of preparation method for 3D printing wood materials, it is characterised in that the tool of this method
Body step is as follows：
1) wood powder is put into microwave dryer and dried more than 6 hours with 70 DEG C -80 DEG C of temperature, its water content is down to 1%
Below；
2) wood powder being dried to obtain, glass microballoon, coupling agent are added in high-speed mixer and carry out activation process, be sufficiently mixed
5-8 minutes, obtain mixture；
3) mixture obtained in step 2 is added to double-cone type and mixed with PLA, compatilizer, lubricant, glass microballoon, white mother
50 minutes are mixed in conjunction machine to being uniformly dispersed, premix is obtained；
4) premix made from step 3 is added into 3D printing production line and extrudes wire drawing, control a diameter of 1.75mm of silk material.Wherein
Charge door is followed successively by the barrel heat temperature in each area of head：One 150 DEG C -160 DEG C of area, 160 DEG C -170 DEG C of 2nd area, three areas 170
DEG C -180 DEG C, 160 DEG C -170 DEG C of 4th area；
The present invention's has advantages below for bio-based wood materials of 3D printing and preparation method thereof：
1) wood powder is added in component and causes the characteristics of product has timber, the i.e. fragrance with timber, can followed closely, can bore, can dig, can
Japanning；
2) wood powder is added in component, the raw material sources are wide, easily reclaimed, it is degradable therefore with low cost；, can be with and draw ratio is big
Significantly improve the dimensional stability and mechanical property of product；
3) in composite preparation process, according to the physical property of different component, different mixing apparatus are selected to carry out in two times
Mixing, is conducive to the surface active of wood powder and inorganic matter, improves the interface compatibility of material；
