Boron-containing slag waste gelcasting method of silica gel mold with ceramic powder modified full-information surface

Abstract

The invention discloses a boron-containing slag waste gelcasting method of a silica gel mold with a ceramic powder modified full-information surface. The method is characterized by comprising the following steps: adding ceramic powder into silica gel, uniformly carrying out stirring to prepare an ceramic powder modified silica gel, and adjusting viscosity of the ceramic powder modified silica gelby using a silica gel diluent; adding a curing agent into the ceramic powder modified silica gel, uniformly carrying out stirring to obtain a mixture, then uniformly coating the surface of a silica gel mold with the mixture; after the coating is cured, adding an initiator and a catalyst into boron-containing slag waste gelcasting slurry, uniformly carrying out stirring to obtain a mixture, then injecting the mixture into the silica gel mold; carrying out curing at a certain temperature, then carrying out demolding, drying and fettling, and carrying out firing. According to the invention, through the addition of ceramic powder, the electrochemical characteristic (or surface chemical potential characteristic) of the surface of the silica gel is changed, so that C=C double bonds in organic monomer acrylamide molecules in the gelcasting slurry are smoothly opened under the action of the initiator ammonium persulfate, and a polymerization reaction is generated; through the addition of the surface of the ceramic powder modified silica gel, the curing strength of the cured surface of the blank body is completely equivalent to the curing strength of the surface of a metal mold blank body,so that the surface information of the blank body is complete.

Description

technical field [0001] The invention relates to a ceramic powder modified full-information surface silica gel 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...
