Description
Technical field
The invention belongs to 3D printed material manufacturing technology field, relate to and a kind ofly mould compound 3D printed material and preparation method with wood prepared by vegetable fibre and polyolefin plastics.
Background technology
3D prints and is called again rapid shaping technique, also referred to as increasing material manufacturing technology, be that one does not need conventional tool, fixture and lathe, but taking digital model file as basis, successively print to manufacture the technology of arbitrary shape article with the material that metal-powder or plastics etc. have a tackiness.The article that 3D printer can be manufactured are a lot, as aircraft, pistol, and food, human organ, toy for children etc. for another example.3D printing technique is an important breakthrough in world's manufacturing technology field over the past two decades.The integrated of the multidisciplinary technology such as mechanical engineering, computer technology, Numeric Control Technology, Materials science.3D prints the exploitation that the most difficult most crucial technology is printed material.Therefore the focus that the more various multi-functional 3D printed material of exploitation becomes future studies and application is with crucial.3D printed material of the present invention is a kind of novel material, has the performance of timber and plastics concurrently, for 3D prints the selection that more material aspect is provided.
It is that 3D prints conventional a kind of technology that melt extruded is piled up moulding (FDM) technology, and this technology utilizes thermoplastic polymer under molten state, extrudes from printing head, is then frozen into profile thin layer, then being formed by stacking in layer.At present, on market, the conventional polymer materials of this technology is poly(lactic acid) (PLA), acrylonitrile-butadiene-styrene (ABS) (ABS), nylon (PA), Polyphenylene Sulfone (PPSF) and polycarbonate (PC) etc.FDM requires material to have lower condensation shrinking percentage, steeper viscosity-temperature curve and higher intensity, rigidity, thermostability etc.
It is nontoxic, tasteless that polypropylene has, and mechanical property is good, easily processing, and corrosion-resistant, melt temperature is lower, good fluidity, speed of cooling is fast, transparent easy dyeing etc., and advantage all meets the requirement of 3D printing technique to polymer materials, and pp material source is wide, price is low; Polypropylene composites makes its dual nature that has timber and plastics concurrently, and adding of vegetable fibre further reduced polyacrylic condensation shrinking percentage, and the article that print have woodiness touch, has more friendliness.
Polypropylene composites is little as the document of 3D printed material at present.
China Patent Publication No. is that 102276920A discloses a kind of polypropylene composite material, adopt glass fibre, toughner, coupling agent, oxidation inhibitor, lubricant, Nucleating Agent on Pp to carry out modification, the tool intensity of the polypropylene composite material after modification is higher and creep-resistant property is better.But its affinity and heat-drawn wire modification to polypropylene composite material is few, can not meet well printing demand.
China Patent Publication No. is the processing procedure that 101781472A discloses a kind of composite material of plant fiber, it adds coupler and becomes mixing material, with high pass filter muller, mixing material is evenly mixed, it adopts to be mixed into micelle and to make composite finished product to add lubrication prescription, the characteristic that the material after modification has weight saving, is difficult for thermal distortion, thermal shrinkage force is little.But its affinity is not high, can not meets well 3D and print demand.
Single performance boost can not meet the performance requirement of 3D printing technique to polypropylene composites, is badly in need of the application widely in 3D printing technique of a kind of new polypropylene composites.
