Description
Technical field
The invention belongs to 3D printing Material Fields, are related to a kind of environmentally protective 3D printing wood plastic composite.
Background technology
3D printing technique is an important breakthrough of world's manufacturing technology field over the past two decades.It is mechanical engineering, calculates
The multidisciplinary technology such as machine technology, Numeric Control Technology, material science integrates.It is printed material that 3D printing, which is most difficult to most crucial technology,
Exploitation.Therefore developing more various multi-functional 3D printing material becomes the hot spot and key of future studies and application.The present invention
3D printing material be a kind of new material, the performance of timber and plastics is had both, in terms of providing more materials for 3D printing
Selection;
At present, the common polymer material of the technology is polylactic acid in the market（PLA）, acrylonitrile-butadiene-styrene (ABS)（ABS）,
Nylon（PA）, polyphenylsulfone（PPSF）And makrolon（PC）Deng.FDM requirement materials have relatively low condensation shrinking percentage, steeper
Viscosity-temperature curve and higher intensity, rigidity, thermal stability etc..Poly butylene succinate（PBS）As a kind of typical fat
Adoption ester, has many advantages, such as：PBS excellent in mechanical performance is close with general-purpose plastics PE, PP mechanical property；Heat resistance is good, heat
Deformation temperature is close to 100 DEG C；Processing performance is good, can be formed on existing plastic processing common apparatus, be existing
Degradation plastic in processing performance it is best.But pure PBS is since main chain is more regular, crystallinity is high, production cost phase
It is higher to other general-purpose plastics and PLA etc., certain restrictions is received on using.In order to expand and promote the reality of PBS
Using especially in the fields such as packaging, tableware, bottle for cosmetics and drug bottle, disposable medical article, agricultural film, it is necessary to right
PBS is copolymerized or blending and modifying, it is made to meet requirement in performance, and close to general-purpose plastics PE, PP in cost
And PVC etc..And PBS and natural biodegradable polymer material（As starch, lignin, stalk, chitosan and various linen-cottons are fine
Dimension etc.）Blending and modifying can not only keep the composite material after blending that there is degradability, but also can be effectively reduced into
Originally, while natural macromolecular material can be made full use of again, not only green but also low-carbon environment-friendly;
Wood powder/PBS composite materials cause it to have both the double grading of timber and plastics, and the addition of wood powder further reduced PBS
Condensation shrinking percentage, and the article printed has woodiness touch, more friendliness.It is helped by adding in toughener, coupling agent etc.
Agent can improve the comprehensive mechanical property of wood plastic composite of the present invention so that modified PBS composite materials are more suitable for being used as
3D printing material.
Invention content
The purpose of the present invention is to provide it is a kind of can 3D printing wood plastic composite and preparation method thereof.Using PBS with
Wood powder, small molecule crosslinking agent, toughener and other components carry out melt blending by different ratio, to realize crosslinking, toughening and increasing
Strong wait is modified, and finally obtains the wood plastic composite available for 3D printing;
In order to realize the purpose of foregoing invention, the present invention provides following technical scheme：
（1）It is a kind of can 3D printing wood plastic composite, be made of following components in parts by weight：60-80 parts of PBS, wood powder 5-
15 parts, 5-10 parts of toughener, 1-5 parts of coupling agent, 1-5 parts of lubricant, 1-5 parts of dispersant;
（2）The toughener selects one kind in POE, butadiene/butyl acrylate blocks copolymer；The coupling agent selects titanium
One kind in acid esters, Aluminate, silane coupling agent；The lubricant selects one kind in paraffin, PP waxes, PE waxes；The dispersion
EBS is selected in agent;
The advantage of the invention is that：
（1）The present invention uses Wood flour filled PBS, and wood plastic composite is made so that and product has woodiness touch, more friendliness,
It can Partial digestion, more low-carbon environment-friendly;
（2）The wood plastic composite of the present invention has good toughness, and the product size printed by 3D printing technique is steady
It is fixed.
