Limestone powder gelcasting method for aluminum powder modified perfect information surface silica gel mold

Abstract

The invention relates to a limestone powder gelcasting method for an aluminum powder modified perfect information surface silica gel mold. The method is characterized by comprising the following steps: adding aluminum powder into a silica gel to be uniformly stirred to prepare an aluminum powder modified silica gel; adjusting the viscosity of the aluminum powder modified silica gel by using a silica gel diluent; adding a curing agent into the aluminum powder modified silica gel, uniformly stirring the mixture, and smearing the mixture to the surface of the silica gel mold uniformly; after themixture is cured, adding an initiator and a catalyst into the limestone powder gelcasting slurry to be uniformly stirred; injecting the mixture into the silica gel mold; curing the mold at a certain temperature; and demolding, drying, repairing a blank and firing the blank. C=C double bonds in organic monomer acrylamide molecules in the gelcasting slurry are opened smoothly under the action of aninitiator ammonium persulfate to generate a polymerization reaction by adding the aluminum powder to change the electrochemical characteristics (or surface chemical potential characteristic). By adding the aluminum powder to modify silica gel mold surface, the curing strength of the surface of the cured blank is fully equal to that of the surface of a metal mold blank, so that the surface information of the blank is perfect.

Description

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