Abstract
A making method of an aperture connected support comprises the following steps: spraying expansion material powder particles to the aperture connected support, and expanding. The controllable adjustment of the size of the apertures of the support is realized through the making method, and the aperture connected support made in the invention has good uniformity. Porous metal materials prepared by adopting the above porous support made in the invention have the advantages of uniform distribution, arbitrary adjustment of the porosity, and wide uses.
Description
Technical field
The present invention relates to a kind of preparation method of support, relate in particular to the preparation method of the porous support of porosity communication used in porous metal material preparation.
Background technology
Porous metal material is widely used, as can be used as medical embedded material and have the important and special purposes such as treatment osseous tissue wound and bone formation necrosis, and existing this common class material has porous metals rustless steel, porous metals titanium etc.Porous embedded material as osseous tissue wound and the use of bone formation necrosis therapeutic, its porosity should reach 30～80% according to the requirement of different implant sites, and hole is preferably all communicated with and is uniformly distributed, or hole is partly communicated with and is uniformly distributed as required, make it both consistent with the bone growth of human body, alleviate again the weight of material itself, to be applicable to human body, implanted use.
Porous metal material is to take powder sintering as main processing method substantially, in particular for obtaining porosity communication and equally distributed porous metal foam structure, adopts the metal dust slurry dry knot abbreviation foam impregnation method of reburning after organic foam body support frame (the spongy body porous support of porosity communication) above floods in powder sintering in the majority.But the porous support relative aperture of existing porosity communication is excessive, pore wall thickness is excessively thin, thereby the porous metal material distribution that sintering is made is difficult evenly, its porosity is difficult to reach more than 50% simultaneously, has limited its application.
Summary of the invention
The object of the present invention is to provide a kind of aperture to be communicated with the preparation method of support, adopt this preparation method can arbitrarily regulate and control pore wall thickness, the pore size of support, thus the porous metal material that can prepare different porosities, be evenly distributed.
The object of the invention is achieved through the following technical solutions:
Aperture is communicated with a preparation method for support, it is characterized in that: expanding material powder particle spray attachment is communicated with on support in aperture, then carries out expansion process.This preparation method can obtain the controlled aperture of pore size and be communicated with support.
Thereby the porosity of the porous metal material that this support of hole wall raising employing that is communicated with support in order to thicken aperture makes, inventor has adopted a lot of methods in R&D process, as be communicated with on support evenly swabbing in aperture, thickened the hole wall of support etc., but easily there is plug-hole, cause the technical problems such as brace aperture is inhomogeneous, uncontrollable.So inventor is initiative, adopt dexterously absorption, expanding method to prepare aperture, be communicated with support, thereby thicken the pore wall thickness of support, effectively control support pore size, then by post processing, make the porous metal material of different porosities.
More even for the bracket holes wall thickness, the pore size that further make to make, above-mentioned expanding material powder particle spray attachment, after aperture is communicated with on support, is also vibrated operation.
Above-mentioned expansion fashion preferably adopts temperature, absorption, pressure, pH, light, radiation, can also be the expansion of other modes certainly, and being combined with of variety of way.
Above-mentioned expanding material preferably adopts organic polymer expanding material.
Said temperature expands and comprises thermal expansion or cold expansion fashion, and thermal expansion material comprises nylon, polymethyl methacrylate (PMMA), polrvinyl chloride (PVC), NaCl, zinc; Cold expanding material is preferably NIPA etc.
The expanding material of above-mentioned adsorption swelling comprises dried starch, carboxymethyl starch sodium, low-substituted hydroxypropyl cellulose, cross-linking sodium carboxymethyl cellulose, polyvinylpolypyrrolidone, alginic acid, sodium alginate etc.
Above-mentioned pressure expansion material comprises rubber, silicon dioxide, rock (as perlite, obsidian) etc.
Above-mentioned pH expanding material comprises sodium alginate etc.
The present invention has following beneficial effect:
Preparation method of the present invention has realized controlled adjustment to support pore size, and the aperture making is communicated with the aperture good uniformity of support.The porous support that adopts the method to make is prepared porous metal material, and distribution of material evenly, its porosity can be adjusted arbitrarily as required simultaneously, of many uses.
