Red mud waste gelcasting method of metal powder-modified complete information surface silicone mold

Abstract

The invention relates to a red mud waste gelcasting method of a metal powder-modified complete information surface silicone mold. The red mud waste gelcasting method is characterized by comprising thefollowing steps of adding metal powder into silicone, and uniformly stirring, so as to obtain the metal powder-modified silicone; adjusting the viscosity of the metal powder-modified silicone by a silicone thinner, adding a curing agent into the metal powder-modified silicone, uniformly stirring, uniformly coating the surface of the silicone mold, and curing; adding an initiator and a catalyst into red mud waste gelcasting slurry, uniformly stirring, and injecting into the silicone mold; curing at certain temperature, demolding, drying, finishing the blank, and firing. The red mud waste gelcasting method has the advantages that the metal powder is added to change the electrochemical characteristic of the surface of the silicone (or chemical potential characteristic of surface), and the carbon-carbon double bonds in the organic monomer acrylamide molecules of the gelcasting slurry are smoothly opened to generate polymerizing reaction under the function of an initiator (ammonium persulfate); the metal powder is added to modify the surface of the silicone mold, so that the curing strength of the surface of the cured blank is completely equivalent to the curing strength of the surfaceof the blank of the metal mold, and the information of the surface of the mold is complete.

Description

technical field [0001] The invention relates to a metal powder modified full-information surface silica gel mold red mud 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 ...
