Oxide modified full information surface silica gel mold red mud waste injection molding method

Abstract

The invention discloses an oxide modified full information surface silica gel mold red mud waste injection molding method, which is characterized in that oxide powder is added into silica gel and evenly stirred to prepare oxide modified silica gel; the viscosity of the oxide modified silica gel is adjusted by a silica gel diluent; the oxide modified silica gel and a curing agent are evenly stirredand evenly coated on the surface of a silica gel mold; after curing, a red mud waste injection molding slurry material is added with an initiator and a catalyst and evenly stirred and then injected into the silica gel mold; and after curing at a certain temperature, demoulding, drying, trimming and then firing. According to method, the electrochemical characteristics (or surface chemical potential characteristics) of the silica gel surface are changed by adding the oxide powder, so that a C = C double bond in the organic monomer acrylamide molecule in the injection molding slurry material issmoothly opened under the action of the initiator ammonium persulfate to generate a polymerization reaction, and the surface of the silica gel mold is modified by adding oxide, so that the curing strength of the cured blank surface is completely equal to that of the metal mold blank surface, and the blank surface information is complete.

Description

technical field [0001] The invention relates to an oxide-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 soft s...
