Description
Technical field
The present invention relates to zirconium oxide granulating technique field, is specially a kind of modeling base oxygen for being applied to injection moulding ceramic product
Change zirconium and be granulated preparation method for material.
Background technology
The zirconium oxide granulation material for being used for injection molding technique manufacture zirconia ceramics product domestic at present, is cured base oxidation
Zirconium granulation material, i.e., need to add auxiliary material Witcodur 272 in main material zirconia powder, be with the shortcomings that this cured base zirconium oxide granulation material：1.
There is no enough mobility, the product that manufacture single-piece zirconia ceramics base substrate weight is more than 25 grams, or the length of side can not be injection moulded
Backboard of the size more than 250mm, panel, appearance member, curved-surface piece, three D structural members etc..2. to injection molding base in production process
When body carries out degreasing link, cured because containing in granulation material, in 100 DEG C or so of debinding furnace during degreasing, be bound to discharge vaporization
Go out it is cured so as to air generation environment pollute.3. short time consumption is needed during degreasing link when 24 is small, consumption electric power, combustion gas money
Source is more.4. the base substrate after degreasing generally required when being sintered in high temperature kiln 130 it is small when or so, consumption electric power, combustion gas resource are more.
These shortcomings are all the places for needing us to change, so as to improve the preparation effect of zirconium oxide granulation material.
The content of the invention
It is an object of the invention to provide a kind of modeling base zirconium oxide granulation material preparation for being applied to injection moulding ceramic product
Method, the modeling base zirconium oxide granulation preparation method for material that should be applied to injection moulding ceramic product comprise the following steps that：
S1：Weighing and proportioning in proportion is carried out to raw material major ingredient and auxiliary material, raw material placement is spare after weighing and proportioning；
S2：It is granulated in all-in-one machine and feeds to automatic mixing, the raw material of weighing and proportioning in S1 is added to inner cavity has been warmed up
Automatic mixing be granulated in all-in-one machine, the temperature that automatic mixing is granulated after the preheating of all-in-one machine inner cavity is at least 50 DEG C；
S3：It is kneaded for the first time, mixing granulation all-in-one machine is risen to 130 DEG C -180 DEG C in inner cavity temperature, to the raw material of addition
It is kneaded, mixing time is 10-30 minutes；

DEG C carrying out second is kneaded, and mixing time is 30-50 minutes；
S5：Third time cooling is kneaded, after second is kneaded, by mixing be granulated all-in-one machine inner cavity be cooled to 100 DEG C-
150 DEG C are kneaded, and mixing time is 30-50 minutes；
S6：Extruding pelletization, setting mixing are granulated all-in-one machine 30-50 revs/min of rotating speed of extrusion, 50-60 revs/min of speed of agitator
Clock, 50-60 revs/min of pelletizing rotating speed, then automatic-extrusion, pelletizing；
S7：Packaging, the granulation material particle diameter extruded after pelletizing is 1-5mm, when naturally cooling to 25 DEG C or so, is packed.
Preferably, the raw material matched in the step S1 is as follows by weight：Major ingredient is：Zirconium oxide 74.3%-89%, it is auxiliary
Expect be：Plastics rheological agent 1%-3%, polymethoxy dimethyl ether 0.3%-1.5%, one acetate ethylene copolymer 0.5%- of ethene
1.6%, erucyl amide 0.2%-1%, EVA3Dispersant 1%-2%, polyethylene glycol oxide 0.5%-2.8%, oxalic acid 7.5%-
13.8%.
Preferably, the major ingredient zirconium oxide is at least 93% yttrium stable zirconium oxide powder for content.
Preferably, the oxalic acid can also be replaced by polyformaldehyde.
Compared with prior art, the beneficial effects of the invention are as follows：Good fluidity of the present invention, applied to injection moulding ceramics
During product, it is entirely capable of producing the product that single-piece zirconia ceramics base substrate weight is more than 25 grams, or size dimension more than 250mm's
Backboard, panel, appearance member, curved-surface piece, three D structural members etc., when carrying out degreasing link to injection molding base substrate in production process,
Because being free of cured, the exhaust gas without evaporative emission air in 100 DEG C or so of debinding furnace in granulation material, reach the mesh of environmental protection
, degreasing link short time consumption simply need to be less than 10 it is small when, largely save electric power, the resource such as combustion gas, the base substrate after degreasing is in high temperature
Normally only needed during sintering in kiln 90 it is small when or so, it is same a large amount of to save the resources such as electric power, combustion gas.

Deng, it is cured because being free of in granulation material when carrying out degreasing link to injection molding base substrate in production process, in 100 DEG C or so take off
Exhaust gas without evaporative emission air in fat stove, achievees the purpose that environmental protection, degreasing link short time consumption simply need to be less than 10 it is small when,
It is a large amount of to save the resources such as electric power, combustion gas, the base substrate after degreasing normally only needed when being sintered in high temperature kiln 90 it is small when or so, equally
It is a large amount of to save the resources such as electric power, combustion gas.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art the invention discloses technical scope in, technique according to the invention scheme and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
