Description
Technical field
The present invention relates to the technical fields of stone grinder, and in particular to a kind of abrasive grain holding intensity is high, wearability is good, heat-resisting
The good diamond dry grinding disc of property.
Background technique
Being poured dry grinding disc is mainly the stone material cut surface being ground after cutting, and preceding working procedure is metal saw blade, can be with after sawing
It is directly bright using dry grinding disc grinding and polishing, make glossiness of the sawing face with surface with as, dry grinding disc grinding is finished and just no longer needed
Want grinding and polishing.
Currently, have the casting type diamond dry grinding disc for stone material grinding, but its there are the following aspects
The problem of: 1, abrasive grain holding intensity low, and abrasive grain, which is underutilized, just to fall off；2, what is be ground wears no resistance, and grinding is caused to exist
Carcass strength is low in dry milled process, and diamond sink, and does not play its grinding and uses；3, thin dry grinding disc during the polishing process, stone
Phenomena such as material surface discolouration and adherency residue, the luminosity of stone material is made not increase, or even therefore the stone material of processing is scrapped；4, it dry grinds
There are gross blow holes on piece surface, and gross blow hole is uncontrollable, and using the bubble removing method vacuumized, then manufacturing cost is high and is not easy to realize
The temperature control of mold.
Therefore, the present inventor makes further research this, develops a kind of casting dry grinding sheet material, thus this case generates.
Summary of the invention
Technical problem to be solved by the present invention lies in a kind of casting dry grinding sheet material is provided, there is abrasive grain to hold intensity
Advantage high, heat-resist, wearability is good can be improved processing effect, reduce processing cost.
In order to solve the above technical problems, the technical solution of the invention is as follows:
A kind of casting dry grinding sheet material, each component and mass percent are as follows:
Bonding agent 30-40%
Diamond abrasive 10-15%
Silicon carbide 5-10%
White fused alumina 5-10%
Filler 20-30%
Toughener 1-5%
Coupling agent 0.5-2%
Defoaming agent 0.3-1%
Further, bonding agent is one of epoxy resin, phenolic resin, melamine resin or a variety of.
Further, diamond abrasive granularity is -3000 mesh of 50 mesh.
Further, filler is one of aluminium oxide, zinc oxide, ice crystal, tin oxide and cerium oxide or a variety of.
Further, toughener is one of liquid nitrile rubber, polyvinyl butyral and polyvinyl acetate or a variety of.
Further, coupling agent is silane coupling agent.
Further, defoaming agent is one of polyethers defoaming agent and organic silicon defoamer.
A kind of casting dry grinding disc, including base and abrasive material working lining, the base are the hairs by textle layers and nylon adherent buckle
The surface of textle layers is arranged in the composite layer that face or hook surface are bonded together by polymeric adhesive, abrasive material working lining,
The textle layers are any one in polyester fiber cloth, canvas, cotton or non-woven fabrics.
After adopting the above scheme, due to have simultaneously in formula of the invention added with silane coupling agent, in molecule can and
The chemically combined reactive group of inanimate matter material, and the reactive group in conjunction with organic matter materials chemistry, can be very good to improve
The physical and mechanical properties such as bending strength, compression strength, the shear strength of dry grinding disc carcass, and improve profit of the filler in resin
It is moist and dispersed, so as to improve the wearability of dry grinding disc and improve processing effect；Added with toughener, Ke Yigai in formula
The brittleness of kind carcass, improves the comprehensive mechanical property of product；Added with defoaming agent in formula, dry grinding disc surface and inside can be eliminated
Gross blow hole, can not only improve product appearance, the service life of product can also be extended.Dry grinding disc production method partial pressure is made
Type and two kinds of moulding by casting, at present mostly producer by the way of compression moulding.The dry grinding disc carcass that this method is produced
Densification, internal almost pore-free, sharpness is poor in use for such carcass, and thermal diffusivity is also poor, leads to plate table
Face is unintelligible, and luminosity does not increase.The present invention is by the way of moulding by casting, so that it may the problem above very good solution.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of present invention casting dry grinding disc.
Label declaration
12 abrasive material working lining 2 of base's 1 textle layers, 11 nylon adherent buckle
Specific embodiment
The invention will be further described in the following with reference to the drawings and specific embodiments.
A kind of casting dry grinding sheet material, each component and mass percent are as follows: bonding agent 30-40%, diamond abrasive
10-15%, silicon carbide 5-10%, white fused alumina 5-10%, filler 20-30%, toughener 1-5%, coupling agent 0.5-
2%, defoaming agent 0.3-1%.
Further, bonding agent is one of epoxy resin, phenolic resin, melamine resin or a variety of.Epoxy
Resin has excellent adhesion energy, and cure shrinkage is small, and hardness is high, and flexibility is preferable, to alkali and most of solvent-stable, often
As purposes such as casting, dipping, lamination material, bonding agent, coating.Epoxy resin has strongest cohesive force, to metal, nonmetallic
Equal multiple materials have very high cohesive force.This is highly convenient for that various filler materials are added in grinding tool, and is filling grinding tool
It has higher intensity in the case where material large percentage.Secondly, epoxy resin also has certain heat resistance, epoxy resin with
There is 200-300 DEG C of heat resistance after anhydride-cured.
Phenolic resin has been widely used in grinding tool industry, heat resistance, preferable toughness and wearability with higher.In phenol
Contain a large amount of phenolic hydroxyl group in urea formaldehyde, highly cross-linked structure can be formed in a heated condition with cured epoxy resin.This
System maintains the good adhesion of epoxy resin, and maintains the heat resistance of phenolic resin, makes phenolic resin resin/epoxy
Resin can be used for a long time at 260 DEG C.
Melamine resin has biggish chemical activity, and very high glue-joint strength, water-resistant capacity is high, can undergo three
Hour or more boiling water, thermal stability high and low temperature ability to cure is compared with strong, wearability is good, quick solidifying, is not required to plus curing agent.
Further, diamond abrasive granularity is -3000 mesh of 50 mesh.Diamond abrasive, it is extremely hard, it can play well
Ablation.Silicon carbide is in irregular shape, more crisp, and sword is fast out when grinding and polishing, and the abrasive material as auxiliary diamond can play enhancing
Sharp effect；White fused alumina shape is more regular, can increase the wear resistance of dry grinding disc.
Further, filler is one of aluminium oxide, zinc oxide, ice crystal, tin oxide and cerium oxide or a variety of.
Further, toughener is one of liquid nitrile rubber, polyvinyl butyral and polyvinyl acetate or a variety of.
Further, coupling agent is silane coupling agent.The trade mark has a KH550, KH560, KH570, KH792, DL602, DL171 this
Several models.
Further, defoaming agent is polyethers defoaming agent (trade mark can be B-455, B-456, B-457 etc.), organic silicon defoamer
One of (trade mark can be DF-22, DF-103, DF-886 etc.), BYK-A555, preferably BYK-A555.
