Gelcasting method for zinc slag waste material by using aluminum powder modified silica gel mold with full-information surface

Abstract

A gelcasting method for a zinc slag waste material by using an aluminum powder modified silica gel mold with a full-information surface is characterized by comprising the following steps: adding aluminum powder in silica gel and uniformly stirring to prepare aluminum powder modified silica gel, adjusting the viscosity of the aluminum powder modified silica gel by using a silica gel diluent, addinga curing agent to the outside of the aluminum powder modified silica gel, stirring uniformly and then uniformly coating the surface of a silica gel mold, after curing, adding an initiator and a catalyst in zinc slag waste material gelcasting slurry, stirring uniformly, and then injecting into the silica gel mold, and after curing at a certain temperature, demolding, drying, fettling and firing toobtain the final product. By addition of the aluminum powder, the electrochemical characteristics (or surface chemical potential characteristics) of the surface of the silica gel are changed, C=C double bonds in organic monomer acrylamide molecules in the gelcasting slurry are successfully opened to carry out polymerization reaction under the effect of ammonium persulfate as the initiator, by addition of the aluminum powder, the surface of the silica gel mold is modified, thus, the curing strength of the surface of a cured blank is completely equal to the curing strength of the surface of theblank of a metal mold, and the surface information of the blank is complete.

Description

technical field [0001] The invention relates to an aluminum powder-modified full-information surface silica gel mold zinc 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 t...
