Abstract

The invention discloses a method for preparing a ceramic molding die. The method comprises the following steps: a, mixing materials: adding gypsum powder, a pore former and glass fibers into ceramic aggregate as a raw material and mixing to obtain a mixed raw material; b, firing the mixed raw material obtained in step a, controlling the firing temperature at 500-600 DEG C, and then raising the temperature to 1500-1600 DEG C at a speed of 40-50 DEG C/h, carrying out heat preservation for 5-6 hours and cooling to obtain a molten liquid; and c, casting the cooled molten liquid into a cast die for molding so as to form a ceramic die and finally coating a wear-resistant film on the surface of the ceramic die. The production process is simple, by adding the pore former and the glass fibers, the phenomena of cavities and pits in the produced ceramic die can be effectively prevented, the temperature rise can effectively guarantee that the manufactured ceramic die has greater stability and by virtue of coating the film, the wear resistance can be increased and thus the service life of the ceramic die is greatly prolonged.

Description

A kind of preparation method of ceramic mould
Technical field
The present invention relates to a kind of preparation method of mould, particularly relate to a kind of preparation method of ceramic mould.
Background technology
Widely use mould pressing ceramic tile in Production of Ceramics process, traditional shaping mould therefor is all gypsum mold substantially, and gypsum mold determines tile shape and visual appearance.Gypsum mold water-intake rate is comparatively large, and porosity is higher, but the very low production of physical strength, surface irregularity, acidproof, alkali resistance is poor, and use rear mold table table easily to occur a large amount of pit, cavity, cause the major defect of ceramic, work-ing life is short.Always pressed brick embryo is contacted with Die and mould plate with powder during use, its shortcoming is because the viscosity of powder is not easy the demoulding, with the Die and mould plate of powder Long contact time, easy adhesion powder, in production process, need often to carry out clean to Die and mould plate, when particularly suppressing the ceramic tile surface of mirror effect, to the more loaded down with trivial details inconvenience of the clean test of mould.
Therefore, for solving the problem, spy provides a kind of new technical scheme.
Summary of the invention
The invention provides a kind of preparation method of ceramic mould.
The technical solution used in the present invention is:
A preparation method for ceramic mould, comprises following processing step:
A, batch mixing: with the ceramic aggregate of 30-40 weight part for raw material, then the glass fibre adding the terra alba of 20-40 weight part, the pore forming agent of 5-8 weight part and 6-10 weight part carries out being mixed to form mixing raw material;
B, fired by the raw material in step a, the temperature fired controls at 500-600 DEG C, then heats up with the speed of 40-50 DEG C/h, carries out isothermal holding after temperature rises to 1500-1600 DEG C, is incubated and cools after 5-6 hour, forms liquation;
C, cooled liquation is cast in casting mold shaping, forms ceramic die, finally at ceramic die plated surface one deck wear-resistance thin film.
Further, described pore forming agent is bicarbonate of ammonia, starch or polyvinyl alcohol.
Further, described ceramic aggregate is useless porcelain powder, quartz sand or sintered bauxite.
The invention has the beneficial effects as follows: production technique is simple, by increasing pore forming agent and glass fibre, can effectively prevent the ceramic die produced from occurring the phenomenon of cavity, pit, risen by temperature again and effectively can ensure that the ceramic die manufactured has higher stability, plated film simultaneously, can abrasion resistant effect be increased, substantially prolongs work-ing life.
