Definitions

  • the invention relates to a grinding arrangement consisting of a sanding belt and a stationary support element and a method for Making an abrasive belt for this arrangement.
  • the distance between the Bottom of the warp yarn and the highest point of the sewing thread in the order of 0.3 to 0.5 mm are at a center distance of the fiber strands of 1.8 mm.
  • This is supported in the grinding zone Sanding belt over its highest places on the back the support structure of the grinding machine. If the Support structure formed by stationary support elements over which the sanding belt slides can the uneven shape of the back of the sanding belt have a strong abrasive effect, especially if the support elements provided with graphite-containing sliding surfaces are that stretched over pressure bars the friction between Back of the sanding belt and pressure bar surface should decrease. You tried that roughness on the back of the underlay due to a fleece overlay to reduce (WO 86/02306); however this is very complex.
  • the invention is based, which wear and tear of the back of the grinding tool on the support structure of the grinding machine reduce and reduce the mechanical properties to improve the grinding tool.
  • the ingredient stiffens the one that encloses it Layer and thereby increases the resistance of the tool. While it was previously required this resilience through suitable selection the hardness, the layer thickness and the penetration depth of the Backsize finish can affect this Parameters can now be chosen more freely.
  • the invention is based on the finding that on the one hand the so far usual, hard settings of the rear side finish the wear properties of the tool adversely affect, and that second a soft adjustment of the rear side finish wear caused by the back of the tool reduced.
  • Lubricants such as graphite dust
  • a variety of lubricant-penetrated fiber bundles Sewing threads in their entirety can be low-friction Sliding and contact surface of the sanding belt form opposite the support element.
  • the softness or wearability of the back finish is expediently chosen so that the highest back places after about one Tenth of the intended life of the sanding belt largely for the formation of low-sliding areas are worn out. This corresponds to marketable products with a duration of about in half an hour.
  • the armoring effect of the platelet-shaped particles is better, the more they are arranged parallel to the tool extension.
  • An advantageous embodiment of the invention is therefore characterized in that the directional component running parallel to the tool extension predominates in the alignment of the particles. This can also be favorable with regard to the sliding and wear properties of the tool.
  • a multiple mutual overlap of neighboring particles also contributes to the stiffening. This is especially true when the particles are tightly attached to the back surface of the base and are also close to each other.
  • Such a state can be achieved according to the invention by ensuring that the finish, at least in a manufacturing phase in which the strip runs horizontally or slightly inclined, is so low-viscosity that the particles accumulate near the rear surface of the base.
  • the particles form a layer sedimented on the back of the underlay, while that part of the finish on the back that is closer to their free surface is largely free or significantly poorer in particles.
  • the advantages of this construction lie on the one hand in the improved stiffening effect of the particles and on the other hand in the fact that they are absent in the outermost finishing zone, which is decisive for the sliding properties, and can therefore be chosen without regard to their sliding properties.
  • a high specific weight of the substrate is advantageous for lowering the particles onto the back surface of the base, for example in the order of 5 g / cm 3 .
  • the amount of the ingredient applied to the back of the base should be at least 3 g / m 2 , preferably more than 8 g / m 2 .
  • the proportion of ingredients in the cured rear side finish should preferably be more than 8% by weight, for example around 15% by weight.
  • the ingredient advantageously contains layer-crystalline particles, which are also preferred should have in the sliding direction.
  • Iron mica has proven to be excellent. Likewise, other types of mica can be used are, expediently in context with a comparatively soft Binder.
  • Binders especially synthetic resins and Plastic dispersions or mixtures of such Fabrics.
  • Backside finishes have proven their worth made from phenolic resin-latex mixtures.
  • the comparatively soft back finish according to the invention preferably contains as a binder component in the not yet hardened state phenolic resin and an acrylic hemester copolymer dispersion in one Weight ratio of 1: 2.
  • phenolic resin and an acrylic hemester copolymer dispersion in one Weight ratio of 1: 2.
  • iron mica proved possibly in combination with other ingredients or fillers, as advantageous, especially when using a graphite press shoe surface as a support element.
  • FIG. 1 comprises a textile underlay consisting of a cross-laid scrim 1 and a longitudinal laid scrim 2, which means Sewing threads 3 composed as a knitted fabric are.
  • the textile layer is through one in the drawing core finish not appearing in itself solidified, bears on the front of a grain layer 4, which by means of a base binder layer 5 and a cover binder layer 6 is bound and is provided on the back with a rear finish, which are only shown in the left half of FIG. 1 is between the level of contact Fiber strands 1 and 2 and the highest points of the Sewing threads 3 form depressions 8, which with the Backside finish mass 7 to be filled.
  • the backside finish is carried out in such a way that in the spaces 8 a has much greater thickness 9 than on the inflated Place the fiber strands 2 and the sewing threads 3.
  • the excess is applied by means of a Doctor knife, so that the highest Points of the threads 3 not or only a little of the Backside finish 7 are covered.
  • the particles accumulate near the base a little bit in area 12, while near the surface Area 13 becomes poorer in ingredient. It takes place then partly when drying, partly by drawing in a certain amount of binder in the textile layer Loss of substance in the finish from the back Formed layer 7 instead, so that this in the wells 8 comes up a little and the wave structure of the Document emerges. Still, the gaps are more filled than in the prior art is common.
  • Threads 3 either occur after manufacture emerge without coating or lose at the latest after a short period of operation due to wear Line 11 the thin coating on them and then form wing elements 10 for the Creation of those grinding machine structures that a pressure on the sanding belt from the back exercise.
  • the sewing threads in the Back appear at regular intervals in such a way that such a surface element 10 on a Grid of 1.7 x 1.1 mm comes.
  • mica has been linked to of the invention under the trademark MIOX the Kärntner Montanindustrie GmbH, Klagenfurt, distributed product proven, its particles Average diameter 40 ⁇ m and thickness of 2-4 ⁇ m.
  • Comparative tests were carried out with two abrasive belts, which corresponded in terms of the backing, finish and grain application formed by a sewing fabric and differed only in that one was finished on the back in a conventional manner, while the other was provided with a backside finish according to the invention.
  • This consisted of 50 parts by weight of phenolic resin and 100 parts by weight of latex dispersion with a solids content of 25 parts and 20 parts of MIOX iron mica of the classification given above. The amount applied was 25 g / m 2 (dry).
  • the one achieved according to the invention is even more striking 4, in which the Mass decrease of the felt in grams over the Operating time is plotted in hours, you will namely less than half of the conventional Felt loss reduced.
  • the rigidity of the tape according to the invention was considerably larger than that of the conventional one.
