Abstract
The invention discloses a kind of methods for preparing 3D printing nitride powder material with sugar for adhesive, it is characterized in that, first, nanometer ceramic powder of titanium nitride is granulated, make its partial size in 50 ~ 100 μ ms, then in grinder, it is added by mass percentage concentration, granulation titanium nitride titanate ceramics powder: 88% ~ 94%, grinding, temperature rises to 120 ± 2 DEG C, addition stearmide: 0.5% ~ 2%, grind 30min, temperature continues to rise to 190 ± 2 DEG C, white sugar: 4% ~ 10%, trien: 0.4% ~ 1.5%, calgon: 0.4% ~ 1.5%, grinding, obtain 3D printing nitride powder material, in the range of its partial size is 80 ~ 120 μm.The 3D printing nitride powder material with it is laser sintered can straight forming, sphericity is high, good fluidity, and formed precision is high, and has simple process, and production cost is low, easy to industrialized production.
Description
Technical field
The present invention relates to a kind of preparation methods of laser sintered 3D printing rapid shaping powder body material, belong to rapid shaping
Material Field, in particular to it is a kind of to be beaten with sugar for the method for adhesive preparation 3D printing nitride powder material and laser sintered 3D
It is printed as type.
Background technique
Sugar is refined sugar made of the molasses squeezed out sugarcane and beet, is by each molecular dehydration contracting of glucose and fructose
The disaccharide of irreducibility made of conjunction, is heated to 160 DEG C, is just melted into thick transparent liquid, crystallizes again when cooling.
Extending heating time, sucrose are decomposed into glucose and anhydrofructose.Under 190 ~ 220 DEG C of higher temperature, sucrose is just dehydrated
Condensation becomes caramel.Caramel has very strong cementation, can make powder adhesion together, play the role of binder.It adopts
Sugar is used to replace chemical adhesive as adhesive, reduce environmental pollution problem.
Titanium nitride (TiN) is a kind of new material, has the characteristics that hardness is high, fusing point is high, chemical stability is good, and
It with golden yellow metallic luster, therefore is a kind of good infusibility wear-resistant material, and a kind of welcome cash equivalent decoration
Material.With the small structural material of wetting of metal and electric conductivity with higher and superconductivity, high-temperature structural material can be applied to
And superconductor.Titanium nitride is quite stable compound, at high temperature not with the metal reactions such as iron, chromium, calcium and magnesium, TiN earthenware
Crucible does not also work under CO and N2 atmosphere with acid slag and basic slag, therefore TiN crucible is the rigid liquid of research and some element phases
The excellent container of interaction.TiN is heated lose nitrogen in a vacuum, generates the lower titanium nitride of nitrogen content.
Laser sintered 3D printing belongs to a kind of method of increasing material manufacturing.This technique is also to lead to using laser as energy source
Crossing laser beam is sintered the powder of plastics, wax, ceramics, metal or its compound equably in processing plane.On the table
The uniform very thin powder of layer overlay as raw material, laser beam under control of the computer, by scanner with certain speed
It is scanned with energy density by the 2-D data in layering face.After laser beam flying, the powder of corresponding position is just sintered into centainly
The entity lamella of thickness, the place that do not scan still maintain loose powdered.After this layer scanned, then need under
One layer is scanned.Thickness degree i.e. layering thickness is first cut according to object and reduces workbench, powdering roller again spreads powder
It is flat, new one layer of scanning can be started.Repeatedly, until scanning through structure at all levels.Remove excessive powder, and passes through and locate later
Reason, can be obtained product.
In existing moulding material field, since SLS rapid shaping technique has the structure of raw material sources multiplicity and part
Build the time it is shorter the advantages that, therefore have wide application in rapid shaping field.But most of is organic material and composite wood
Expect, discloses a kind of nylon powder material for laser sintering and moulding product in Chinese invention patent CN1379061A, pass through
The improvement of chemical synthesis and technique handles the surface of nylon powder material, and it is excellent to have obtained sintering character, moulded products
Intensity is high, and the product of good toughness simplifies the preparation process of laser sintered nylon material, reduces costs；Chinese invention patent
A kind of laser sintered 3D manufacturing technology stone plastic composite powder end and preparation method thereof is disclosed in CN103881371.
The application will obtain 3D printing nitride powder material with carbohydrate gum stick hot coating to titanium nitride surface after granulation
Laser sintered 3D printing molding can be directly used.Sprinkling adhesive is not needed in forming process.Advantage is that adhesive dosage is big
Big to reduce, adhesive used is reduced environmental pollution using sugar, and the quality of product is high.The 3D of the technique preparation of the application is beaten
Nitride powder adhesive coating uniform is printed, surface is smooth, good fluidity, and laser sintered 3D printing is suitble to form.In addition,
Preparation method provided by the present application is simple, at low cost.
Summary of the invention
Mesh of the invention is to provide a kind of method for preparing 3D printing nitride powder material with sugar for adhesive, fast rapid-result
Type nitride powder material does not need sprinkling binder can Direct Laser scanning molding；
The purpose of the present invention is achieved through the following technical solutions.
