Oxide-modified full information surface silica gel mold urban sludge gelcasting method

Abstract

The invention relates to a oxide-modified full information surface silica gel mold urban sludge gelcasting method, which is characterized by comprising the following steps: adding oxide powder into silica gel and evenly stirring to prepare oxide-modified silica gel; adjusting the viscosity of the oxide-modified silica gel by using a silica gel diluent; additionally adding a curing agent into the oxide-modified silica gel, evenly stirring, and evenly applying onto the surface of a silica gel mold; after curing, adding an initiator and a catalyst into urban sludge gelcasting slurry, stirring evenly to obtain a mixture and injecting the mixture into the silica gel mold; and after curing at certain temperature, demolding, drying, fettling and firing. In the invention, the electrochemical characteristic (or the surface chemical potential characteristic) of the surface of the silica gel is changed by adding the oxide, so that C=C double bonds in organic monomer acrylamide molecules in the gelcasting slurry are smoothly disconnected under the action of the initiator ammonium persulfate to undergo polymerization reaction; and the surface of the silica gel mold is modified by adding the oxide, so that the curing strength of the cured surface of a blank body is completely equivalent to the curing strength of the surface of a metal mold blank body, and the surface information of the blankbody is complete.

Description

technical field [0001] The invention relates to an urban sludge injection molding method for an oxide-modified full-information surface silica gel mold, 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 ...
