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 metal powder modified full-information surface silica gel mold boron slag waste gelcasting method, which is characterized by comprising: adding metal powder into silica gel,uniformly stirring to prepare metal powder modified silica gel, uniformly stirring the metal powder modified silica gel and a curing agent, uniformly coating the surface of a silica gel mold with theobtained mixture, and curing; adding an initiator and a catalyst into boron slag waste gelcasting slurry, uniformly stirring, and injecting the obtained mixture into the silica gel mold; and curing ata certain temperature, demolding, drying, fettling, and firing. According to the invention, by adding the metal powder, the electrochemical characteristics (or surface chemical potential characteristics) of the silica gel surface are changed, so that the C=C double bonds in the organic monomer acrylamide molecules in the gelcasting slurry are smoothly opened under the action of an initiator ammonium persulfate to generate a polymerization reaction; and by adding the metal powder to modify the surface of the silica gel mold, the curing strength of the cured billet surface is completely equal to that of the metal mold billet surface, so that the billet surface information is complete.

Description

technical field [0001] The invention relates to a metal powder modified full-information surface silicone mold boron slag 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 to use...
