Problems solved by technology

[0005] However, the study found that the organic monomer acrylamide in the in-situ injection molding slurry will inhibit polymerization on the surface of the soft silicone mold, resulting in incomplete curing of the ceramic slurry at a depth of 0.5-1mm on the surface, and the surface of the green body will be damaged during demoulding. will flake off, ruining the expressive surface

Abstract

The invention discloses a purple sand waste gel-casting method for a ceramic powder-modified full-information surface silica gel mold. The purple sand waste gel-casting method comprises the followingsteps: adding ceramic powder into silica gel and stirring uniformly to prepare ceramic powder-modified silica gel; adjusting a viscosity of the ceramic powder-modified silica gel with a silica gel diluent; adding a curing agent into the ceramic powder-modified silica gel to be stirred uniformly, and then uniformly brushing on a surface of a silica gel mold; after curing, adding an initiator and acatalyst into purple sand waste gel-casting slurry to be stirred uniformly, and then injecting into the silica gel mold; and after curing at a certain temperature, demolding, drying, fettling and thenfiring. According to the invention, the ceramic powder is added to change electrochemical properties (or surface chemical potential properties) so that C=C double bonds in organic monomer acrylamidemolecules in gel-casting slurry are successfully opened under action of the initiator ammonium persulfate and subjected to polymerization; the ceramic powder is added modify the surface of the silicagel mold, so that a curing strength of the surface of a cured green body is completely equal to the curing strength of the surface of a metal mold green body, and the surface information of the greenbody is complete.

Description

technical field [0001] The invention relates to a ceramic powder modified full-information surface silica gel mold purple sand waste injection molding method, which belongs to the technical field of ceramic material preparation. Background technique [0002] With the continuous improvement of living standards, people's requirements for the beautification and original ecology of the home environment and social public environment continue to increase. However, every artist or artist needs to spend a lot of time, money and energy to create a work. It cannot satisfy people's pursuit of beauty, so there is an urgent need for a method that can reproduce the exquisite works of artists or artists in large quantities at low cost; [0003] Every exquisite work of art is expressed by full-information surfaces such as creative graphics and graphic surface textures, animal skin hairs, and surface bumps, so their shapes are extremely complex. The best way to solve the above problems is t...
