Description

A kind of zirconium aluminium pottery grinding stone and preparation method thereof
Technical field
The present invention relates to field of ceramic preparation technology, specifically a kind of zirconium aluminium pottery grinding stone and preparation method thereof.
Background technology
Grinding is both a kind of ancient processing method and a brand-new technical field.It is worldwide wide General use especially in terms of the Precision Machining of machinery manufacturing industry, is ground and many departments is generated with very important influence.
China is the country for applying method for grinding earliest in the world, and into after 21 century, abrasive material production is rapid into one In the period of development, quickly, this growth indicates the increase of Precision Machining part in machinery manufacturing industry, but also reflects for increase of production Go out increasing considerably for the non-grinding application percentage of abrasive material.This is mainly used for national defence and the Al for manufacturing fine ceramics and using2O3 With SiC micro mists, dosage has reached the 40% of total yield.
Currently on the market, mainly there is grinding for Brown Alundum (white fused alumina) material for the abrasive polishing materials of piece surface processing Grinding stone, the plastic cement grinding stone of resin material, alumina porcelain (high frequency porcelain) rotten-stone, vibropolish steel ball, all kinds of grinding agents, all kinds of light Bright dose etc., the major function of these abrasive polishing materials is as shown in the table：
Abrasive media includes the abrasive polishing materials such as grinding stone, rotten-stone, grinding agent, gloss agent, each material has certainly Oneself application range, if plastic cement grinding stone is for the softer material of material, such as aluminium, zinc, copper, plastics；Ceramic-like grinding stone is used In the harder material of material, such as iron, stainless steel, galvanized iron, steel；Material is polished as the part of iron, it is necessary to use iron gloss agent, Polishing material for copper part, it is necessary to use copper luster agent, hand-held tool cutting agent for all kinds of spanners, sleeve, batch nozzle go black film, Descale, if for other parts, it would be possible to can burn into destruction part.
Ceramic grinding stone is mainly used for the softer product surface of the materials such as aluminium alloy, kirsite, copper, resin (plastics) and throws Light, fine grinding before plating are usually used in family property hardware (such as knob, lockset) and luggage (such as belt fastener, bag buckle, shoe buckle), main There are circular, triangle, oblique triangle, garden cylindricality, oblique garden cylindricality.Ceramic grinding stone has mainly formed aluminium oxide, zirconium oxide, oxygen Change magnesium, calcium oxide, silica, titanium oxide, the oxide-based ceramic of iron oxide；Such as nitridation of aluminium nitride, silicon nitride, titanium nitride Species ceramics；Such as carbon compound ceramics of carborundum, titanium carbide, tungsten carbide；The borides pottery of such as zirconium boride, titanium boride Porcelain etc..
As ceramic grinding stone binding agent, for example, can be that polyethylene, polypropylene, ethylene-vinyl acetate copolymer etc. are poly- Alkene；The acrylic resins such as polymethyl methacrylate, polybutyl methacrylate；The styrene resins such as polystyrene； The polyester such as polyvinyl chloride, Vingon, polyamide, polyethylene terephthalate, polybutylene terephthalate；Polyethers； Polyvinyl alcohol；The various resins such as their copolymer；Various waxes；Paraffin；Higher fatty acids (such as stearic acid)；Higher alcohol；It is high Grade aliphatic ester；The various organic binder bonds such as higher fatty acid amides.
Using high molecular material as binding agent, this requires carry out ungrease treatment (at de- binding agent to shaping entity Reason), it is usually hot briquetting body, so as to remove no-bonder from formed body.And make binding agent using high molecular material, it is molded Product surface roughness is big, and abrasive power is not high, and long-time service abrasive power declines；And product hardness is low, and density is low, it is difficult to be used for Process hard metal.
The content of the invention
Present invention aims at provide a kind of density is high, stock-removing efficiency is high, the grinding stone suitable for processing hard metal and its Manufacturing method.
Realize foregoing invention purpose technical solution：
A kind of zirconium aluminium pottery grinding stone, weight composition are ZrO243-48 parts, Al2O338-42 parts, Cr2O3 1.2- 1.8 parts, 3.5-4.5 parts of CaO, Na2SiO33-4 parts, TiCl40.4-0.6 parts；
Its preparation process is as follows：
(1) metering is carried out according to proportioning to weigh；
(2) batch mixing, by ZrO2、Al2O3, Cr2O3, CaO by stirring and ground and mixed it is uniform
(3)Na2SiO3And TiCl4It adds in, first by Na2SiO3Weight concentration is made into as 5-10% aqueous solutions, is gradually added TiCl4, it is kept stirring in adition process, forms a kind of homogeneous system；
(4) material of step 2 and step 3 is mixed, water is added to be uniformly mixed；
(5) according to the requirement of product, corresponding mold is selected, carries out die cast；
(6) product of die cast is dried；
(7) product sinter molding after drying.
It is preferably matched：ZrO245 parts, Al2O340 parts, Cr2O31.5 parts, 4.0 parts of CaO, Na2SiO34 parts, TiCl40.5 part.
Die cast pressure is 300MPa-400MPa.
Drying temperature is 300-350 DEG C.
1450 DEG C -1520 DEG C of sinter molding temperature.
The features of the present invention and effect
Use Na2SiO3Aqueous solution and TiCl4Reaction forms a kind of uniform colloid, substitutes traditional high molecular material and makees For binding agent, reduce degreasing in preparation process (de- binding agent) step；Due to the use of inorganic binder, inside grinding stone Structure is finer and close, Na2SiO3With TiCl4Hydrolysate forms titan silicate colloid, improves the flexural strength of product, and anti-folding is strong Degree improves 5-10MPa, and density reaches 3.5-3.6g/cm3, can be used in the machining of hard metal, improve stock-removing efficiency 15- 20%.
