Abstract
The present invention relates to a kind of ceramic material, preparation method and applications.Preparation method includes：Dispersant, thickener, ceramic powder and plasticizer are mixed, mixture is obtained；Alkaline solution is added into mixture while stirring；Continue to stir, then carry out it is aging, to obtain ceramic material；Wherein, plasticizer is acidic silicasol, and pH is 3~6, a concentration of 5~30wt.%；The particle that ceramic powder includes the particle that grain size is 30~50nm and grain size is 0.5~1 μm, accounting is respectively 3~20wt.% and 80~97wt.%.Since acidic silicasol itself carries charge, therefore ceramic powder surface can be adsorbed on, in subsequent preparation process, with alkaline solution is added while stirring, the sol particle of dispersion occurs polymerisation, generates gel, gel network makes to be cross-linked with each other between ceramic particle, Interaction enhanced between particle makes the plasticity of ceramic material improve, while also having higher solid content.
Description
Technical field
The present invention relates to technical field of ceramic material more particularly to a kind of ceramic material, preparation method and application.
Background technology
Ceramic material has penetrated into various fields, environmentally friendly, energy saving, chemical industry, oil, smelting, food, pharmacy, biology doctor
Etc. multiple scientific domains all be unable to do without ceramic material.Extrusion molding, compression moulding, tape casting and 3D printing molding are ceramics
The important process of preparation, by favor due to its is simple and practicable, at low cost.But with the development of ceramic technology and product structure
Adjustment, the proportion that lean property blank accounts for is increasing, and particularly with high-grade household china and function ceramics, lean property blank content is up to
80% or more, cause that slurry plasticity is low, forming quality is poor, and as influencing industrial major technical barrier.
In general, it is high-ductility pug that plasticity index, which is more than 15, and plasticity index is plastic mud material, modeling between 7~15
It is inductile pug that sex index, which is less than 7,.From the point of view of domestic existing working condition and research conditions, addition plasticizer is to obtain height
The maximally efficient method of plastic mud material.
Presently used plasticizer mainly has two major classes：Inorganic plasticizer and organic plasticizer.Inorganic plasticizer
Mainly clay class, organic plasticizer have polyvinyl alcohol, methylcellulose, starch etc..These plasticizer can be to lean property
Grain carries out absorption and aquation, and the interaction between moisture film reinforcing particle is shared by generation, to realize that pug is plasticized.In order to take
Good plasticizing effect, the dosage of these plasticisers is often larger (dosage is generally higher than 15wt.%), along with itself compared with
High viscosity causes the solid content of pug that cannot further promote (solid content is generally below 60wt.%), increases ceramic follow-up
The difficulty of sintering.In addition, there may be problem of environmental pollutions, residue can also reduce ceramics in burn off for organic plasticizer
Functional characteristic.The measures such as ball milling, optimization size grading, aging can improve the plasticity of ceramic material to a certain extent, but
The effect of plasticizer cannot be substituted.
Invention content
(1) technical problems to be solved
It is big for existing ceramic material plasticizer consumption, there is pollution etc., application is insufficient, the present invention provides a kind of novel ring
The method for plasticizing of guarantor：By the interaction between the gelation process reinforcing particle of colloidal sol, to improve the plasticity of ceramic material.
(2) technical solution
In order to solve the above technical problem, the present invention provides following technical solutions：
A kind of preparation method of ceramic material, the preparation method include the following steps：
(1) dispersant, thickener, ceramic powder and plasticizer are mixed, obtains mixture；
(2) alkaline solution is added into the mixture while stirring；
(3) continue to stir, then carry out it is aging, to obtain the ceramic material；
Wherein, the plasticizer is acidic silicasol, and pH is 3~6, a concentration of 5~30wt.%；
The particle that the ceramic powder includes the particle that grain size is 30~50nm and grain size is 0.5~1 μm, accounting are respectively
3~20wt.% and 80~97wt.%.
Preferably, the alkaline solution is selected from ammonia spirit, the aqueous solution containing bicarbonate radical, contains the water-soluble of carbonate
Liquid, the aqueous solution containing acetate, the aqueous solution containing citrate or any one of containing aqueous solution hydroxy, preferably
For ammonia spirit, the ammonia spirit of further preferably a concentration of 10~20wt.%.It is further preferred that the alkaline solution
Quality account for 0.02~0.08wt.% of the mixture quality；
The quality of the acidic silicasol accounts for 22~26.6wt.% of the mixture quality.
Preferably, the ceramic powder is alumina ceramic powder or zirconia ceramics powder, and quality accounts for the mixture
73~77.6wt.% of quality.
Preferably, the dispersant is selected from any one of glycerine, phosphate, olein or triethanolamine, matter
Amount accounts for 0.1~0.3wt.% of the mixture quality.
Preferably, the thickener is selected from any one of sodium carboxymethylcellulose, polyvinyl alcohol or polyethylene glycol, quality
Account for 0.3~0.5wt.% of the mixture quality.
Preferably, the time of the stirring is not less than 30 minutes, preferably 30~40 minutes；
The aging time is 48~60 hours.
A kind of ceramic material is made using preparation method described in any of the above-described.Preferably, the plasticity of the ceramic material
Index is 15~18, and solid content is 70~78wt.%.
Above-mentioned ceramic material is being molded any molding work using extrusion molding, compression moulding, tape casting or 3D printing
Skill prepares the application in ceramic product.
