Description
Technical field
This utility model belongs to increasing material manufacturing technology field, and the rapid shaping particularly to a kind of photocuring pottery idiosome sets
Standby.
Background technology
Ceramic material has high temperature resistant, corrosion-resistant, the feature of high intensity, is widely used in machinery, electronics, Aeronautics and Astronautics
In field.The production technology of pottery generally includes preparation and two steps of high temperature sintering of ceramic blank.The realization of above-mentioned steps needs
To pass through corresponding former.Traditional blank-making technology includes plastic molding, injection forming, the technique such as compressing, wherein
Plastic molding is the technique that pottery mud is manually processed into base substrate, and this technique is time-consuming, laborious and precision is the highest；And injection forming, pressure
The type of making is that ceramic size is injected mould inside, until slurry shape after, opening mold and obtain ceramic body.This moulding process
Precision is higher, but product consistency is relatively low, die cost is higher, and the production cycle is longer, and this blank-making technology can only produce knot
Structure rule, the ceramic being convenient in demoulding, it is difficult to meet the production of complex-shaped ceramic.The beginning of the nineties U.S.'s Oak Ridge state
Family's development in laboratory is for the gel injection molding and forming technology of ceramic body, by organic monomer, cross-linking agent, initiator, catalyst
Join in ceramic slurry, be configured to the slurry that viscosity is relatively low, ceramic powder content is higher, by high pressure injection moulding equipment,
Slip is injected in the cavity body of mould closed, by mould is heated, utilizes temperature to cause organic monomer to occur polymerization anti-
Should, it solidify to form ceramic body.This ceramic body has that formed precision is good, consistency is high, the defect of goods is less, the production cycle
Short feature, but injection forming equipment needed for this moulding process and mould is relatively costly, and use this technique only

Chinese patent CN104493952 A reports a kind of employing gel column mould 3D printing technique and prepares gradient ceramic
Method, the method use computer-controlled slide unit drive extruder head, at sample stage apparent motion, light sensitive ceramics slurry is existed
Sample stage surface deposits, and in slurry, resin occurs rapidly curing reaction under the effect of firming agent, makes material base fast shaping.This sets
The standby preparation that can realize labyrinth ceramic, but shaping speed compared with slow, goods precision is relatively low.
The Zhou Weizhao of domestic Xi'an Communications University develops a kind of direct ceramic molding based on photocuring, uses Asia
Bisacrylamide, silicon dioxide, dispersant and light trigger etc. prepare photocuring light sensitive ceramics slurry, systematic research
The parameters such as dispersant dosage, ceramics particle diameter, ceramics volume content, the impact on ceramic workpiece SLA Stereolithography technique
Rule.The sample stage of this former is positioned at ceramic size, and the laser beam utilizing galvanometer to drive is carried out on ceramics sample surface
Quickly scanning, after completing the molding of a tangent plane, sample stage toward ceramic size internal sink a slice thickness, after will by scraper plate
The ceramic size on surface strikes off, and then proceeds by the molding of next tangent plane.This equipment is only suitable for that viscosity is less, solid content relatively
The rapid shaping of low ceramic size, and for solid content compared with high, slurry viscosity big, the ceramic size of poor fluidity, at sample
Platform sinking watching and scraper plate frictioning process, easily cause local starved or model is damaged, and uses pottery in this technique slip
Powder volume content is up to 55%, and powder content is relatively low brings impact to final ceramic workpiece consistency, intensity.Thus this molding
Equipment can not meet the manufacture demand of high-quality ceramic body.
Chinese patent CN104387105A reports a kind of 3D printing association reaction sintering and prepares porous alumina ceramic material
The method of material, the method uses 3DP quick shaping process, at the binding agent of alumina ceramic powder surface spraying definite shape,
The rapid shaping of the method quick implementation model section then irradiated with ultraviolet light, but use the ceramic material prepared by this technique
The high Effect on Mechanical Properties to pottery of porosity is relatively big, and utilizes ink-jet printer to carry out spraying and adhesive bonding agent at powder surface
Speed is relatively slow, and production efficiency is relatively low.There is the problem that porosity is high, in addition this device too in ceramic body prepared by this device
The high power laser used is expensive, makes ceramic body production cost increase.
Thus, develop and a kind of facilitate feasible ceramic batch former, become raising ceramic quality, widen pottery
The key in product application field.
