Embodiment Construction

[0007] In the powder of ceramic slurry, in 1 kg of ceramic powder, by mass percentage, add enter 5 grams of ammonium polyacrylate with a pH value of 7-8, 1 gram of 0.8 / % ammonium dithionate, content of 0.15-0.25 g / 1 gram of ammonium ethacrylate, according to the mass ratio, AM acrylamide monomer: aluminum sulfate crosslinking agent 3 grams of the composition of 1:20 is mixed with water to form a ceramic slurry. The ceramic slurry is injection molded, cured at a temperature of 60-70°C, and fired at a temperature of 1580°C after demoulding to become a finished ceramic product.

Abstract

The invention relates to a ceramic blank rubber base consolidation forming method. The method comprises the following steps of: adding 5 grams of ammonium polyacrylate of which the pH is 7 to 8, 1 gram of 0.8 mass percent diammonium sulfate, 1 gram of 0.15 to 0.25 mass percent ethyl ammonium acrylate and 3 grams of composition of acrylamide monomer (AM) and aluminum sulfate cross linker in a mass ratio of 1: 20 into 1 kilogram of powder of ceramic slurry, adding water, stirring to form the ceramic slurry, performing injection molding on the ceramic slurry, solidifying at 60-70 DEG C, stripping, firing at the temperature of 1,580 DEG C, thus obtaining a ceramic finished product. According to the method, because the AM and the cross linker are added in the ceramic blank powder, so that the ceramic slurry has cohesiveness and is easily formed and early solidified, and the strength and the quality of the ceramic blank can be improved. The ceramic slurry is applied to preparation of ceramic blanks.

Description

technical field [0001] The invention relates to ceramics in the field of non-metal, in particular to a rubber-based solidification molding method for ceramic green tires. Background technique [0002] The existing ceramic green body is that ceramic powder is added with water and stirred to form a slurry, then poured into a mould, and after absorbing water and solidifying, it is demoulded to become a ceramic green body. Because water is directly added to the ceramic powder, it becomes muddy, and after the water is absorbed by the mold, the ceramic green tire is condensed and formed by the cohesive force of the mud itself. The ceramic green tire made by this method has low strength and long demoulding time, which affects the quality and strength of the ceramic green tire. Contents of the invention [0003] In order to increase the strength of the ceramic blank, shorten the demoulding time and improve the quality, the invention proposes a rubber-based solidification molding ...
