Description
Technical field
Usually, the present invention relates to a kind of abrasive material, wherein, abrasive grain is embedded in the adhesive stroma, and wherein for grinding work-piece the contact surface that is covered by abrasive grain is set.
Background technology
Since beginning to develop such abrasive material, people just know the grinding composite that will prepare homogeneous texture.For this purpose, use inelastic adhesives at first, and elastic compliant adhesive (elasticallycompliant binder) has used decades.Using an example of the grinding composite of inelastic adhesives is grinding stone.The example of using the grinding composite of elastic compliant adhesive is a densified composite, for example with cubical form or form other abrasive material piece (abrasive compact) of emery wheel.Known in this respect existing porous non-porous embodiment also arranged.These known abrasive material piece past are the whole foundry goods that the successful record of proof is put into practice more than 40 years that remain now by the applicant.
So far, because they are as the structure of abrasive material piece, these known use abrasive grains are made normally with the abrasive material of elastic compliant adhesive, and need not in abrasive material in conjunction with material.On the contrary, for the abrasive material with inelastic adhesives, the term in this part " abrasive material (backedabrasives) that backing is arranged " is in decades all in their kind.
The present invention also is particularly related to abrasive material, and this abrasive material has and the porous corresponding non-porous particularly non-foam adhesive of foam glue particularly.
With reference to German plastics handbook (German Plastics Handbook) " Saechtling KunststoffTaschenbuch, 28
ThEdition, by Karl Oberbach, Verlag Hansa publishes, see 555 pages, Fig. 4 .18 ", no matter where relate to PUR (polyurethane) obviously; still, between foamed material and non-porous adhesive, create a difference usually about the adhesive of all other foaming.
In this case, the basic especially non-porous PUR type of the present invention belongs to group:
Solid polyurethane
Casting and elastomer that spray
Thermoplastic elastomer (TPE)
Rubber
Originally the elastic compliant piece of quoting in the prior art and " solid " composite in the grouping of quoting are respectively special cast elastomeric, and abrasive material of the present invention also uses special cast elastomeric.
When adhesive is made into foam glue, by the material of application of air physical mechanical ground foaming and by creating a difference between the material that uses the blowing agent chemical blowing.
The abrasive material with non-porous adhesive for the present invention relates to is characterized in that, by corresponding curing handle that operation is carried out neither physics neither chemistry the target foaming.It is to expand in order as much as possible to avoid that target substitutes, although in fact always can not avoid the formation of remaining porous fully.In Here it is the abrasive product that why specific design is made being described as market at least, preferably with reference to real and theoretical density than practice.
In order to make the adhesive foaming, by PUR mode is as an example illustrated this comparison best.When German plastics handbook " Saechtling Kunststoff Taschenbuch, 28 that reading is quoted
ThEdition, by Karl Oberbach, Verlag Hansa publish, and see 554 pages and following or the like ", the foam (30-300kg/m of moulding
3), rigid foams (30-90kg/m
3) and open celled foam (20-40kg/m
3) between create a difference.
According to the present invention, used particularly to have the 800kg/m that is not less than that has fully described minimum porosity
3The PUR of density.
Wherein abrasive composites has shown porous particularly the adhesive that backing is arranged of the feature of foam glue is open in for example German patent DE 3114001A1 and the DE 1907983A1.
In a word, The present invention be more particularly directed to abrasive material, contain the composite of the resinoid of abrasive grain.At this, the present invention is used for the thermosetting plastics of the adhesive of composite abrasive grain by known conduct, and polyurethane for example is although rubber also can be used for the present invention as the adhesive that is used for abrasive grain.
An example of the thermoplastic adhesives that are used for abrasive grain of pyroxylin (colloxyline) form of the plasticising among the Deutsche Bundespatent DD 106585A, be different from the thermosetting plastics that uses in the scope of the invention, also need use plasticizer in 1: 1 or 0.8: 1 with ratio about equally.The filling ratio that also needs to control abrasive material is for grinding at least 60 weight % of abrasive powders in the composite, surpasses 80% with respect to the ratio of abrasive powders and regarded as by way of parenthesis bonding grinding composite is harmful to.The thickness that ad hoc proposal is arranged to the thin layer of abrasive material when measuring perpendicular to backing (backing) with this known grinding composite is the grinding composites of 10 μ m to maximum 40 μ m.
Just for the purpose of completeness, also with reference to how external known abrasive material, but so the kneading adhesive that is used for abrasive grain conclude and be suitable for the surface of the work profile (Deutsche Bundespatent DD255903A1) that is used to grind.
In technology development process as the abrasive material that comprises process velocity at present, for example rotation or the swinging operation in grinding tool or grinding machine side all becomes faster all the time, the even abrasive material with elastic compliant adhesive of Chan Shenging acceleration that comprises centrifugal force and the tractive force that impotentia opposing produces that becomes in decades, need not special measurement, the result is damaged too early by the abrasive substrate that the elastic compliant adhesive forms.One of these special measurements of using with emery wheel comprise the size of the abrasive coating of the solid core that measures emery wheel, make abrasive material more and more thinner, produce short relatively valid expiration date.For the annular abrasion band, almost just considered before half a century with bar shaped and grind the endless belt of composite coating as backing, submissive foaming by polyurethane forms the matrix that contains abrasive grain in each case, these abrasive grains are fixed on the endless belt in the bonding mode of separating and (see BP GB B 821929, particularly walk to the 7th row for the 2nd page the 3rd) thus., owing to must stop and grind the bonding of composite and relevant separation, the main points of this invention make irrational complicated approach become necessity, the reason that Here it is can not get the nod in practice in producing continuously.
Grind for the corrosivity of routine, always the mode by for example initial hide glue of inelastic adhesives and present artificial resin directly is adhered to abrasive grain on the backing usually, and the size of described abrasive grain is that as required result selects.This backing has absorbed tractive force and the centrifugal force that results from the machine.Under this regular situation, abrasive grain only with independent layer attached on the backing, and give prominence to from the surface of the abrasive material that contact with workpiece by the abrasive material jut.These juts in grinding during loss, adhesive immediately with the workpiece CONTACT WITH FRICTION, the efficient of grinding significantly descends, and load the adhesive on wear of work surface be damaged.
Be arranged in equably by the abrasive material in the radiation curing inelastic adhesives matrix on the bonding backing of adhesive for abrasive grain, this matrix is divided into the matrix body that leaves the space mutually of a plurality of dispersions, backing has been played the effect (Deutsche Bundespatent T2 69210221) that increases the cross section that is parallel to this backing in the direction with the free contact surface of workpiece.
In other words, in the corrosion grinding abrasive part of the abrasive grain that protrudes in contact surface, the size of less abrasive grain makes the polishing of wear surface all better.In this respect, need distinguish comprise no longer basically that corrosivity is ground and the peak on surface to the height of paddy reduces, with honing or grind comparable polishing.
For the use of modern grinding machine, provide the abrasive material of abrasive material non-woven fleece now usually as polishing.Can see that from German patent DE-T2 69609709 (particularly claim 4) a plurality of abrasive grains are adhered on the loose fabric of the opening of organic fiber through adhesive systems.The polishing of carrying out produces on processed surface and scabs and crooked or fracture therewith.The defective of workpiece polished surface, for example scratch and scratch are only covered up, and do not remove veritably.
Summary of the invention
The purpose that provides by the described this abrasive material of preorder of claim 1 is provided, this abrasive material is to be suitable as the article that are used for the reasonable amount preparation, as the polishing tool on the modern grinding machine, the height uniformity of long-term service life and quality of finish is combined.

In abrasive material according to the present invention, when contact surface new, that covered by abrasive grain is provided, when the covering epidermis by the release matrix adhesive must be exposed in the final stage of preparation process, produced the part abrasive grain that protrudes in initial first contact surface of workpiece.When realizing polishing, these ledges of abrasive grain are pressed into fully or almost completely are pressed onto in the matrix, have therefore removed the corrosion abrasive action to workpiece basically.Avoid or minimized at least the load of the wear surface of workpiece, because when covering the abrasive grain loss of matrix, the adhesive that stays around previous does not carry out load with wear of work surface and contact (loading contact), but as the wearing and tearing of rubber.In this set, abrasive grain is loss like this not, but little by little drops from current contact surface.This abrasive grain loss is from the depths cyclic regeneration of matrix, and therefore, during polishing, no matter the consumption of matrix, the quality of polishing still is consistent.In fact, this in addition involve whole consumption of the matrix that is connected with backing.In this set, backing has been guaranteed consistent crudy, no matter matrix is depleted to any degree, even at very high machined parameters, for example rotary speed, rate of bending or vibration rank, only several procedure of processings just can realize of the present invention rational and have a manufacturing of cost-benefit abrasive material simultaneously.
Also wanting ben is that abrasive material of the present invention combines the improvement that can realize above possible so far with the polishing machine in modern times.Therefore, compare with grinding non-woven fleece, the attainable product of the present invention of non-woven fleece is relevant with the minimum degree corrosive effect of the abrasive grain that further adds with grinding, thus according to the present invention, the defective of lapped face not only can be hidden now, and can eliminate or correct at least.Now, be unexpectedly, do not need further polishing, chromium workpiece subsequently goes for this.
By selecting the type of adhesive, any operable filler and abrasive grain, wearing and tearing have been determined basically.In order to process various materials, for example brass, aluminium or stainless steel can be adjusted adhesive.Abrasive material of the present invention is effective especially when polishing more coarse relatively surface of the work.Even when the abrasive grain in the abrasive material of the present invention was more coarse, these surfaces also can be polished very fine surface and not have defective now.
After decades out in the cold, by by means of the elastic compliant adhesive in the matrix, run counter to current developing trend and realized all these.
