Problems solved by technology

[0005] However, the study found that the organic monomer acrylamide in the in-situ injection molding slurry will inhibit polymerization on the surface of the soft silicone mold, resulting in incomplete curing of the ceramic slurry at a depth of 0.5-1mm on the surface, and the surface of the green body will be damaged during demoulding. will flake off, ruining the expressive surface

Abstract

The invention relates to a gel casting method for vanadium-titanium tailings through a metal powder modified perfect-information surface silicone mold. The method is characterized by comprising the steps that metal powder is added to silicone for even stirring to prepare metal powder modified silicone, a silicone diluent is adopted for adjusting the viscosity of the metal powder modified silicone,a curing agent is added to the exterior of the metal powder modified silicone for even stirring, the surface of the silicone mold is evenly coated with the mixture, after curing, an initiator and a catalyst are added to gel casting slurry of the vanadium-titanium tailings for even stirring, the mixture is injected to the silicone mold, after curing at a certain temperature, demolding, drying andfettling are conducted, and then sintering is conducted. According to the gel casting method, by adding metal powder, the electrochemical characteristic (or the surface chemical potential characteristic) of the silicone surface is changed, C=C double bonds in organic monomer acrylamide molecules in the gel casting slurry are smoothly opened to generate a polymerization reaction under the effect ofthe initiator ammonium persulfate, by adding the metal powder modified surface silicone mold, the curing strength of the cured blank surface is completely equal to that of the blank surface of the metal mold, and information of the blank surface is complete.

Description

technical field [0001] The invention relates to a metal powder modified full-information surface silica gel mold vanadium-titanium tailing 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 problem...
