Method for gel-casting red stoneware residues for metal powder modified full-information silicone mold

Abstract

The invention provides a method for gel-casting red stoneware residues for a metal powder modified full-information silicone mold. The method is characterized by comprising the following steps: addingmetal powder into silica gel, and uniformly stirring to prepare metal powder modified silica gel; regulating the viscosity of the metal powder modified silica gel by adopting a silica gel diluting agent; adding a curing agent to the metal powder modified silica gel, uniformly stirring, and uniformly coating to the surface of a silica gel mold; curing, adding initiator and catalyst into red stoneware residue gel-casting slurry, uniformly stirring, and injecting into the silica gel mold; and curing at a certain temperature, demolding, drying, fettling and burning. According to the method, the electrochemical characteristic (or surface chemical potential characteristic) of the silica gel surface is changed by adding the metal powder, so that the C=C double bonds in an organic monomer acrylamide molecule in the gel-casting slurry can be smoothly opened under the effect of initiator ammonium persulfate to generate a polymerization reaction; and by adding the metal powder modified silica gel mold surface, the curing strength of a cured blank surface is completely the same as that of the metal mold blank surface, and the blank surface has complete information.

Description

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