Problems solved by technology

[0002] At present, the zirconia granules used in the injection molding process to manufacture zirconia ceramic products in China are all wax-based zirconia granules, that is, the auxiliary material microcrystalline wax needs to be added to the main raw material zirconia powder. The disadvantages of granulated materials are: 1. There is not enough fluidity, and it is impossible to produce products with a single piece of zirconia ceramic body weighing more than 25 grams by injection molding, or back plates, panels, appearance parts, and curved surface parts with side leng

Abstract

The invention discloses a method for preparing a plastic-based zirconia granulation material applied to injection molding of ceramic products. The method for preparing the plastic-based zirconia granulation material applied to injection molding of ceramic products comprises the specific steps: S1, weighing and proportioning main ingredients and auxiliary materials of raw materials; S2, loading in an automatic mixing and granulating integrated machine; S3, performing the first mixing; S4, performing the second mixing; S5, performing the third cooled mixing; S6, performing extrusion pelletizing; S7, packaging. The fluidity is high, and when the material is applied to the injection molding of ceramic products, products in which a single zirconia ceramic body has the weight of more than 25g can be completely manufactured, waste gases in evaporative emission for polluting atmosphere do not exist in a debinding furnace at the temperature of about 100 DEG C, the aim of environment friendliness is achieved, the time consumption only needs to be less than 10 hours at the debinding link, and lots of power, gases and other resources are saved. The ceramic body subjected to debinding only needs to be sintered by about 90 hours in a high temperature furnace generally, and lots of the power, gases and other resources are similarly saved.

Description

technical field [0001] The invention relates to the technical field of zirconia granulation, in particular to a method for preparing a plastic-based zirconia granulation material applied to injection molded ceramic products. Background technique [0002] At present, the zirconia granules used in the injection molding process to manufacture zirconia ceramic products in China are all wax-based zirconia granules, that is, the auxiliary material microcrystalline wax needs to be added to the main raw material zirconia powder. The disadvantages of granulated materials are: 1. There is not enough fluidity, and it is impossible to produce products with a single piece of zirconia ceramic body weighing more than 25 grams by injection molding, or back plates, panels, appearance parts, and curved surface parts with side lengths greater than 250 mm , 3D structural parts, etc. 2. When degreasing the injection molded green body during the production process, because the granulation materi...
