Piece also relates to a kind of preparation method of high-performance diamond composite sheet.
Background technique
Composite polycrystal-diamond (Polycrystalline diamond compact, PDC) is to add diamond dust
After adding certain catalyst and hard alloy substrate to fit together, in superhigh-temperature and-pressure condition on special diamond hydraulic press
Lower sintering is made.In order to improve the wearability of diamond compact, the PDC that silicon makes as bonding agent is upgraded to use by people
Cobalt, nickel, iron make PDC as bonding agent, i.e., will bind directly between diamond particles without being formed, but form D-M-D (Buddha's warrior attendant
Stone-interphase-diamond) structure is transformed into, and mutual direct sintering forms D-D (diamond-gold together between diamond particles
Hard rock combination) integrated structure.Under normal pressure state, the localized hyperthermia that diamond compact generates during the cutting process leads to metal
Bonding agent carries out anticaltalysis effect to D-D chemical bond, reduces the wear-resisting property of diamond compact.
Currently, to solve bonding agent, that is, metal solvent anticaltalysis effect, Chinese patent application publication No. is CN
105156037 A, number of patent application 201510608766.2, a kind of entitled thermostable type composite polycrystal-diamond
And preparation method thereof patent of invention take off the mode of catalyst and obtain de- catalyst treated PDC, although improve hot warm nature and
Wearability.But de- catalyst (bonding agent) processing, the diamond layer for resulting in diamond compact generate gap or hole,
The metal solvent (bonding agent) being filled in diamond compact is lost simultaneously to play in diamond compact impact process
Buffering and hinder micro-crack extend effect, cause diamond compact impact resistance to be sharply weakened, so that its mechanics
Performance cannot give full play to, and even result in compound be not worn of diamond and just impact breakage.Inventor has done the production time thus
Research feel the need to make the prior art improvement to solve the above problems.

A method of high-performance diamond composite sheet is prepared, is included the following steps:
S1: taking diadust, metal solvent, hard alloy substrate to be assembled into assembling block, and it is high that assembling block is carried out high temperature
It is pressed into, it is stand-by that diamond complex is made；
S2: de- catalyst processing is carried out to diamond complex, diamond layer, which is made, has a diamond of hole compound
Body is stand-by；
S3: a diamond complex is cleaned, secondary diamond complex is made after removing the interior residual impurity；
S4: extracting container is placed in resin liquid, and the diamond layer of secondary diamond complex is immersed in resin liquid, gold is obtained
The diamond complex three times of resin liquid is immersed in hard rock layer hole；
S5: handling diamond complex three times so that the resin liquid immersed in diamond layer hole solidifies, and being made has
Four diamond complexes of composite skins；
S6: being machined out processing to four diamond complexes, and the finished product of surface smoothness and size qualification is made.
Further, in S4, the container is put into vacuum evacuation device or high-pressure installation, using the side of negative pressure or high pressure
Formula sufficiently pours resin liquid in the hole.
Further, in S5, resin liquid is solidified into its specific method in the hole of diamond layer: four diamonds are answered
Zoarium takes out merging baking oven or lamp box, carries out heat cure or photocuring to the resin liquid in hole.
Further, in S2, a diamond complex is cleaned specifically: by a diamond complex as pure
Ultrasonic cleaning and drying are carried out in water or alcohol.
Further, the metal solvent is the mixture of any one or more or alloy in Co, Fe, Ni, V, Cr.
Beneficial effects of the present invention: the hole that its interior de- catalyst of diamond layer of the present invention leaves is filled by resin,
Play the role of effectively buffering in diamond compact impact process and micro-crack is hindered to extend, to the diamond after de- catalyst
Composite sheet is reprocessed, and the shock resistance of diamond compact can be improved while not reducing diamond compact wear-resisting property
Performance.It will be further described in conjunction with embodiment in detail below in other beneficial effects of the invention.
