Refuse ash cinder gelcasting method of aluminum powder modified full information surface silicone mold

Abstract

The invention discloses a refuse ash cinder gelcasting method of an aluminum powder modified full information surface silicone mould. The refuse ash cinder gelcasting method is characterized by comprising the following steps: adding aluminum powder into silica gel and uniformly stirring to obtain 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 and then uniformly coating on the surface of a silicone mold; after the aluminumpowder modified silica gel is cured, adding an initiator and a catalyst into refuse ash cinder gelcasting slurry for uniform stirring, injecting a mixture into the silicone mold, curing at certain temperature, demoulding, drying, fettling and then firing. According to the refuse ash cinder gelcasting method disclosed by the invention, the electrochemical characteristics (or surface chemical potential characteristics) of the silicone surface are changed by adding the aluminum powder, so that a C=C double bond in an organic monomer acrylamide molecule in the gelcasting slurry is successfully broken under the action of initiator ammonium sulfate to generate polymerization reaction; by adding the aluminum powder to modify the surface of the silicone mold, the surface curing strength of the cured green body is completely equivalent to that of a metal mold green body, so that surface information of the green body is complete.

Description

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