Abstract
The paint for hard alloy production consists of: high purity metallurgical carbon black 25-28 wt%, flaky graphite 8-10 wt%, polyglycol 3-5 wt%, Turkey red oil 5-7 wt%, Tween 3-5 wt% and negative ion water 48-53 wt%. The paint of the present invention makes hard alloy possess no adhesion to sintering boat, no bending deformation, no surface contamination, no carburization and no decarburization and can ensure the required size precision and quality.
Description
Technical field
The present invention relates to a kind of coating composition, especially a kind of coating that is used for CEMENTED CARBIDE PRODUCTION.
Background technology
The repressed formation pressed compact of cemented carbide powder is deviate from forming agent and is placed on carries out sintering on the graphite boat in sintering oven, becomes final hard metal article.If pressed compact directly places on the boat, sticking boat appears during sintering, and cause shrinkage strain inconsistent, make sintered article flexural deformation, had a strong impact on product's dimensional precision, qualification rate is low.Therefore the technician develop coating that can isolate pressed compact and boat always, avoid occurring gluing boat and the sintered article flexural deformation that produces, the while also not can because of coating cause dirtyization of product surface or cause ooze, decarburization influences quality of item.The now existing coating of forming by high-purity metallurgical carbon black, polyoxyethylene glycol, turkey red oil, polyoxyethylene, glycerol, formaldehyde and anion water, dirtyization of product surface do not appear in the application and ooze, the decarburization phenomenon, also part has solved sticking boat problem, but sticking boat rate still reaches more than 50～60%, the flexural deformation rate is more than 10%, maximum reaches 50%, and for the difference that influences of different hardness alloy raw material, formaldehyde also has a negative impact to operator's health simultaneously.
Summary of the invention
The present invention is directed to above-mentioned deficiency, a kind of universal coating that the sticking boat of sintering cemented carbide, goods are not occured bending and deformation be provided, do not have dirtyization of product surface simultaneously yet and ooze, the decarburization phenomenon, guarantee product size precision and specification of quality.
The present invention is used for the coating material of CEMENTED CARBIDE PRODUCTION, and its moiety and weight percent are: high-purity metallurgical carbon black 25～28%, graphite phosphorus sheet 8～10%, polyoxyethylene glycol 3～5%, turkey red oil 5～7%, polyoxyethylene 3～5%, anion water 48～53%.
With the preparation of above components in certain proportion, mix also and stir, the even suspension liquid brushing that obtains at boat and pressed compact surface in contact, is placed pressed compact and carries out sintering on the boat.It is as follows to produce statistics:
| Coating type | Sintered article | Sticking boat rate % | Flexural deformation rate % | Ooze, decarburization % | Surface dirtyization % |
| Old coating | The clamped cutting bit sheet | ??50～60 | ??45～50 | ????0 | ????0 |
| The mine instrument | ??50～60 | ??8～10 | ????0 | ????0 | |
| The shovel snowflake | ??70～80 | ????0 | ????0 | ????0 | |
| Coating of the present invention | The clamped cutting bit sheet | ????0 | ????0 | ????0 | ????0 |
| The mine instrument | ????0 | ????0 | ????0 | ????0 | |
| The shovel snowflake | ????0 | ????0 | ????0 | ????0 |
Statistic data shows, new coating of the present invention not only because the new coating of introducing cause dirtyization of product surface and ooze, the decarburization phenomenon, the more important thing is and sticking boat phenomenon do not occur, sintered article does not have flexural deformation, thereby quality of item and dimensional precision all be guaranteed, and reduced the sintering waste product, improved product percent of pass, saved cost and suitable equally, had universal for the hard metal article of different material.
Embodiment
Embodiment 1, weight percent is respectively 25% high-purity metallurgical carbon black, 10% graphite phosphorus sheet, 5% polyoxyethylene glycol, 7% turkey red oil, 5% polyoxyethylene and 48% anion water mixes, stir, the even suspension liquid that obtains is new coating of the present invention.
Embodiment 2, weight percent is respectively 28% high-purity metallurgical carbon black, 8% graphite phosphorus sheet, 3% polyoxyethylene glycol, 5% turkey red oil, 3% polyoxyethylene and 53% anion water mixes, stir, the even suspension liquid that obtains is new coating of the present invention.
Embodiment 3, weight percent is respectively 26% high-purity metallurgical carbon black, 9% graphite phosphorus sheet, 4% polyoxyethylene glycol, 6% turkey red oil, 4% polyoxyethylene and 51% anion water mixes, stir, the even suspension liquid that obtains is new coating of the present invention.
Embodiment 4, weight percent is respectively 27% high-purity metallurgical carbon black, 9% graphite phosphorus sheet, 5% polyoxyethylene glycol, 6% turkey red oil, 4.2% polyoxyethylene and 48.8% anion water mixes, stir, the even suspension liquid that obtains is new coating of the present invention.
