Abstract
The invention discloses a kind of straight forming 3D pottery printing clay pug, consist of in mass ratio: ceramic aggregate powder body: guar gum powder body: dispersant: thickening agent: deionized water=180～185: 0.4～0.6: 1.0～1.5: 0.2～0.6: 40～70.Additionally, also disclose the preparation method and application of above-mentioned clay pug.Clay pug solid content of the present invention is high, it is dilute functional to cut, it is suitable for straight forming method 3D and prints the preparation of ceramic component, can gradually be dried in 3D print procedure under room temperature condition, solidify, thus obtain set structure without subsiding, printing precision is high, it is possible to meets 3D well and prints the demand of straight forming.
Description
Technical field
The present invention relates to 3D printing technique field, particularly relate to a kind of straight forming 3D pottery printing clay pug and
Preparation method and application.
Background technology
3D printing technique, is according to designed 3D model, successively increases material by 3D printing device and manufacture three-dimensional
The technology of product, this successively stack shaping technology is also referred to as increasing material manufacture.3D prints and combines digital modeling techniques, electromechanics
The numerous areas such as control technology, information technology, material science and chemistry, are the one of rapid shaping technique, are described as " for the third time
The industrial revolution " core technology.
3D printed material mainly includes plastics, metal, resin, rubber, pottery etc..Wherein, ceramic material have high intensity,
The excellent specific properties such as high rigidity, high temperature resistant, low-density, chemical stability are good, corrosion-resistant, in industries such as Aero-Space, automobile, biologies
Have a wide range of applications.But due to the feature that ceramic material is hard and crisp so that it is shape particularly difficult.With metal and plastics etc.
Material is different, and ceramic material cannot be in 3D forming process, and rely on ceramic powder is combined into type.Therefore, 3D prints
Ceramic material, the most generally uses the mixture that ceramic powders is formed with certain binding agent, beats by its 3D of technical process
India side formula is divided into:
(1) successively mull technique, i.e. utilizes nozzle jet binder powder on ceramics bed to be formed, utilizes laser to burn
Knot, carries out heating, solidifying by the powder that this layer needs solidification；The most again layer overlay powder body, and jet binder powder,
So repeating, the powder finally removing non-jet binder i.e. can get stereo object.
(2) straight forming method, is first prepared by mixing into ceramic mud by ceramic powders and binding agent, and 3D passes through when printing
Extrusion is piled up and is directly formed certain shape.
In above-mentioned successively mull technique, owing to the fusing point of adhesive powder is relatively low, simply by adhesive powder time laser sintered
Melt and make ceramic powders be bonded together.After laser sintered, need to put in temperature controlling stove by ceramic, higher
At a temperature of carry out post processing.Wherein the proportioning of ceramic powders and adhesive powder influences whether the performance of ceramic part.Viscous
Knot agent powder deal is many, and sintering is easier, but part shrinkage ratio is relatively big in last handling process, can affect the size essence of part
Degree；Adhesive powder deal is few, then be difficult to thermal sintering.And ceramic powders liquid phase surface tension when the direct Fast Sintering of laser
Greatly, rapid solidification can produce bigger thermal stress, thus easily form more micro-crack.
Compared with successively mull technique, straight forming method can directly print and obtain increasingly complex shape, as tied containing closed pore
Structure (for successively mull technique, the powder body not solidified due to centre cannot take out, and therefore cannot obtain this shape and structure).So
And, pug used by straight forming method needs to have preferably to cut dilute performance, i.e. has less viscosity when 3D prints extrusion；Squeeze
After going out, viscosity quickly increases, so as to keeps sample to have certain shape and do not cave in, thus maintains outside 3D printout
Shape.Clay class ceramic material has good plasticity and caking property, prints straight forming ceramic aggregate as 3D and has significantly
Advantage；But, the structure of clay itself makes it need to adsorb more water could realize flowing, the most just causes slurry admittedly to contain
Measure relatively low, curing molding difficulty, it is easily caused caving in of 3D printout.Therefore, the 3D with clay as ceramic aggregate prints directly
Molding, need that core solves is the thixotropy problem of clay class ceramic size.This is also the most ceramic directly rapid prototyping work
Skill is not yet ripe, reason still in conceptual phase.
