Method for gel-casting rubbish ash into metal powder modified full information surface silica gel mould

Abstract

The invention relates to a method for gel-casting rubbish ash into a metal powder modified full information surface silica gel mould. The method is characterized by the following steps: adding metal powder into silica gel and uniformly stirring, thereby acquiring a metal powder modified silica gel; using a silica gel diluent for adjusting viscosity of the metal powder modified silica gel, adding acuring agent into the metal powder modified silica gel, uniformly stirring and evenly coating on the surface of the silica gel mould; after curing, adding a rubbish ash gel-casting sizing agent intoan initiator and a catalyst and uniformly stirring, and then injecting into the silica gel mould; curing under a certain temperature, and then de-molding, drying, fettling and sintering. According tothe invention, the metal powder is added for changing the electrochemical properties (or surface chemical potential features) of the silica gel surface; C=C double bond in organic monomer acrylamide molecules in the gel-casting sizing agent can be smoothly opened under the action of initiator ammonium persulfate so as to trigger polymerization reaction; the metal powder is added for modifying thesurface of the silica gel mould, so that the curing strength of the cured green body surface is fully equal to that of metal mould green body surface, and the surface information of the green body iscomplete.

Description

Technical field [0001] The invention relates to a method for molding garbage ash and slag of a metal powder 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, social and public environment continue to increase, and each artist or artist creates a piece of work needs to spend a lot of time, money and energy, far It cannot satisfy people's pursuit of beauty. Therefore, there is an urgent need for a way to replicate the fine works of artists or artists in large quantities at low cost; [0003] Each exquisite artwork is expressed by creative graphics and graphic surface textures, animal skin hair, surface bumps and other full-information surfaces, so its shape is extremely complex. Using soft silicone mold and in-situ injection molding method is...
