Description
Technical field
The invention belongs to the laser fast shaping field.A kind of preparation method who is applied to the ceramic powder material of precinct laser sintering for quick formation has particularly been proposed.
Background technology
The stupalith industry is taking place deep and significant the variation under the double excitation of the development in Hi-Tech and the market requirement.Stupalith itself has a lot of good characteristics, in recent years because the development of many new technology novel procesies has further improved the performance of stupalith again, this makes the Application Areas of ceramic product constantly expand, but the high rigidity of stupalith, high-wearing feature make its moulding and processing face very big challenge.A lot of ceramic members are complex-shaped, adopt traditional removal moulding or are forced to moulding process when carrying out moulding, and the moulding difficulty is big, and the scrap rate height is difficult to moulding even.This problem is outstanding to be reflected on the ceramic component for preparing complex construction.(SelectiveLaser Sintering SLS) is expected to solve this difficult problem to existing precinct laser sintering technology.
A kind of as in the commercialization in the RP technology of SLS because it possesses the diversified characteristics of formed material, thereby has been subjected to extensive concern.SLS technology is directly to come moulding by the densification to powdered material, be laser beam under the control of computer according to the section information that obtains by cad data, powder is carried out sintering, after one deck is finished, bed thickness of worktable decline, carry out the shop powder sintering of back one deck again, so the final three-dimensional objects that forms of circulation.Theoretically, any powder that can produce sintering, bonding or curing reaction under heat effect all can be as the SLS formed material.The sharpest edges that the precinct laser sintering technology is compared other rapid shaping techniques are restrictions that it does not have the materials used aspect, can moulding the part of random geometry almost, to containing cantilever design (Overhangs), the part manufacturing of grooving in hollow structure (Hollowedareas) and the groove (Notches within Notches) structure is effective especially.Briefly say, after all are heated mutually the powdered material of gluing or surface be covered with thermoplastic (Gu) powder of property bonding agent all can be used as the SLS material.But, studies show that, the material that really is suitable for SLS must have good thermoplastic (Gu) thermal conductivity of property, appropriateness, narrower " softening---solidify " temperature range, after laser sintered thermosetting, enough bonding actions to be arranged.
Existing commercial SLS equipment adopts CO more
2Laser source, power is little, wavelength is big, and it is lower to be sintered the temperature that powder reality can reach, and makes that ceramic powder is difficult to be easy to sinter molding as resin, paraffin, metal and ABS plastic.Therefore to carry out surface coating modification to ceramic powder, promptly in ceramic powder, add a certain amount of low melting point binding agent, ceramic powder is coated processing, in laser sintered process, fusing takes place and ceramic powder is bonded together in binding agent, becomes the model that can carry out following process, have certain intensity.
At present, the used binding agent of ceramic powder that is applied to laser fast shaping comprises three kinds of mineral binder bond, organic binder bond and metal adhesives etc.For example, adopt mineral binder bond primary ammonium phosphate (NH
4H
2PO
4) coated aluminum oxide (Al
2O
3) powder; Adopt organic binder bond methyl methacrylate (Polymethyl Methacrylate is called for short PMMA) to coat silicon carbide (SiC) powder etc.; At aluminum oxide (Al
2O
3) add metal adhesive Al powder etc. in the ceramic powder.In the technical study of SLS forming process of ceramics, adopt PMMA as binding agent coating ceramic powder more.The add-on of binding agent is very big, makes that the shared volume fraction of ceramic powder in the base substrate is too small, and problems such as cracking, distortion appear in the base substrate of laser sintering (SLS) easily in last handling process.People (Cheng Jun, Bai Peikang, Liu Bin etc. such as Cheng Jun for example.The peritonaeum ceramic powder material that is used for laser sintering fast formed ceramic parts.The patent No. 02110360.7) at the resin-coated class organic membrane in ceramic powder surface, make ceramic powder can be used for laser sintering rapid forming.The weight ratio of wherein organic overlay film and ceramic powder is that the composition and the consumption of 72.01～415.02: 1000. its organic peritonaeums is respectively: wetting agent 1～5 gram of anhydrous sorbitol lipid or alkyl polyoxyethylene ether class, lubricant 1～10 gram of paraffin or stearic acid or butyl stearate, dispersion agent 0.01～0.02 gram of nonionogenic tenside or anion surfactant or aggretion type tensio-active agent, polyvinyl acetate (PVA), the polypropylene acid esters, polystyrene, polypropylene, ethylene copolymer, polyamide-based, organic resin 60～300 grams of the different melting points of thermoplastic polyester combination, flow promotor 10～100 grams of silicon dioxide powder or silicon carbide or silicon nitride powder.The ceramic powder that coats obtains the powder of 160～300 order granularities behind ball milling.The consumption of surface peritonaeum is big, and problems such as cracking, distortion appear in base substrate easily that be shaped on the SLS instrument in last handling process.
