Description

A kind of composition, preparation and its application for fused glass pellet 3D printing
Technical field
The present invention relates to a kind of composition, preparation and its application based on fused glass pellet, and in particular to one kind is used for The preparation method and applications of the high-molecular wire rod with micron order hole of fused glass pellet 3D printing, belong to increasing material manufacturing Field of functional materials.
Background technology
Over nearly twenties years, as a kind of emerging technology of rapid shaping field, 3D printing technique develops very fast, mesh It is preceding to be applied in fields such as aerospace, biomedicine, defence and military, engineering education, new product developments.3D printing skill Art is also known as increases material manufacturing technology, and different from the method that traditional material removal is processed, it is by way of successively accumulating material Directly manufacture product.3D printing technique can rapidly and precisely produce complicated knot using three-dimensional CAD model in an equipment Structure part, to realize " freely manufacturing ", the limitation that solves the processing of traditional handicraft difficulty or can not process, and substantially reduce processing Period is especially suitable for small lot, personalized, complicated hollow part.3D printing technique includes mainly fusion sediment at present It is molded (Fused Deposition Modeling, FDM), selective laser sintering and moulding (Selective Laser Sintering, SLS), Stereolithography (stereo lithography apparatus, SLA), laminated solid body molding Technologies such as (Laminated Object Manufacturing, LOM), wherein FDM is with fastest developing speed, using most.
FDM refers to that Filamentous thermoplastic material is sent into nozzle by wire feeder, is heated to molten state in the showerhead, is squeezed through nozzle Go out.The filamentary material of molten state is extruded out, and the path controlled according to the individual-layer data of three-dimensional software squeezes and specified Position coagulation forming, layer by layer deposition solidification, eventually forms entire three-dimensional objects.The operating environment of FDM is clean, safe, technique letter It is single, easily operated, and rubbish is not generated, therefore operation occasion has been widened significantly.Its raw materials is carried in the form of spool silk For being easily portable and quick-replaceable.
However the application range of FDM is limited to by material at present, material category make very little the practical performance of 3D printing by Limitation, such as thermal conductivity, sound absorption anti-seismic performance are arrived.Therefore, new FDM 3D printing materials are developed to answer to widen it It is very important with range.
Porous material refers to that foaming agent gasifies or expand in material internal to generate the material of porous structure, can be less Density of material and dosage are reduced under the premise of loss material mechanical property, while meeting the light-high-strength of material and functionality is wanted It asks.Porous material fatigue life is long, have preferable toughness, thermal stability, energy absorption and insulation performance, automobile, household electrical appliances, Electronics, building, consumer goods industries and military field have broad application prospects.The preparation method baseset of current porous product In in conventionally manufactured field, such as supercritical fluid prepares polymer foaming technology, two times opening mold, and required die sinking is costly, Development cycle is long.So this just promotes us to develop a kind of novel 3D printing material, by preparation method and rapid shaping skill Art, which is combined, prepares porous product, to significantly promote the development rate of porous articles, greatly increases to individuation product Supporting dynamics.In addition, this preparation method can be directed to engineering plastics, there is stronger practicability.
Invention content
The purpose of the present invention is overcoming above-mentioned the deficiencies in the prior art, provide a kind of for fused glass pellet 3D printing Composition.
It is a further object to provide one kind being used for fused glass pellet 3D printer, with micron order hole The preparation method of polymeric composition.
Another object of the present invention is to be to provide a kind of application field of above-mentioned composition, you can prepares multiple dimensioned hole The preparation method of the product in hole and the product.
The present invention uses the supercritical CO more than critical pressure and critical-temperature2Fluid utilizes its high density and low The big feature of viscosity, diffusion coefficient, is immersed in polymer base material, then unexpected pressure release, is formed inside polymer base material micro- Meter level hole.
