With reference to fig. 1 to 3, the present application provides a coated abrasive tool, which has a novel structure and a good polishing effect for polishing a product.

Specifically, the coated abrasive comprises: substrate 1 and dull polish portion, dull polish portion locate substrate 1 on the surface, and wherein, dull polish portion includes: a plurality of interval arrangement and be wavy dull polish strip 2, the clearance between the adjacent dull polish strip 2 forms chip groove 3 to dull polish strip 2 extends along the length direction of substrate 1.

According to the structure described above, the plurality of abrasive strips 2 arranged at intervals are arranged on the surface of the substrate 1, so that when a product is polished, the product is in contact with the abrasive strips 2, and then the product is moved or the substrate 1 is pulled to form relative motion, so that the product is polished, and the abrasive strips 2 are arranged in a wave shape, so that in the polishing process of the product, along with continuous consumption of the abrasive strips 2, the contact area between the abrasive strips 2 and the product is always kept unchanged, the polishing effect of the product is better and more stable, the obtained yield is high, on the other hand, the abrasive strips 2 are arranged in the wave shape, and are favorable for being fixed with the substrate 1, and the product is not easy to collapse when polished; when the product is polished at dull polish strip 2, can produce a large amount of sweeps on the product surface simultaneously, the sweeps that drop can fall in chip groove 3 to discharge via chip groove 3, can not pile up on the face of polishing of dull polish strip 2, reduced the area of contact of sweeps with the product, avoid the product to produce the secondary fish tail, improved the effect of polishing.

The frosted portion is bonded to the surface of the base material 1 with an adhesive, and may be provided on one surface of the base material 1 or on both surfaces of the base material 1 as needed for polishing. The frosted part is suitable for polishing the surfaces of metal, putty, coatings or ceramics, and is widely applied to industries of furniture, decoration and the like.

In one embodiment, the distance between adjacent sanding bars 2 is: 2-5 mm. Referring to fig. 2, when the distance between adjacent grinding bars 2 is less than 2mm, the chip discharge grooves 3 formed between the adjacent grinding bars are relatively narrow, the chip discharge grooves 3 are easily blocked by the waste chips generated by grinding, and a user needs to clean the waste chips in the chip discharge grooves 3 in time, so that the grinding efficiency is low and the consumed time is long; when the distance between the adjacent sanding strips 2 is larger than 5mm, the chip discharge grooves 3 formed between the adjacent sanding strips are large, so that certain places on the surface of a product are not sanded, sanding needs to be carried out repeatedly, and sanding efficiency is low. The distance between the abrasive bars 2 is 5mm in this embodiment.

In one embodiment, the cross-section of the sanding strip 2 is rectangular. Therefore, in the polishing process, the contact area between the polishing strip 2 and a product can be ensured to be unchanged, and the polishing effect is improved.

In one embodiment, the width B of the sanding bar 2 is: 0.1 to 1 mm. Referring to fig. 2, when the width of the sanding strip 2 is less than 0.1mm, the contact area between the sanding strip 2 and the product is small, so that the sanding efficiency is low; when the width of the sanding strip 2 is larger than 1mm, the contact area between the sanding strip 2 and a product is larger, so that more materials are easily consumed in the sanding process, and the cost is increased. In this embodiment, the optimal width of the sanding strip 2 is 0.3mm, which not only ensures the sanding effect on the product, but also reduces the loss of materials and reduces the cost.

In one embodiment, the sanding strip 2 includes: protruding section 21 and sunken section 22 of mutual consecutive alternate connection, the corresponding protruding section 21 symmetry sets up between the adjacent emery stick 2, and the corresponding sunken section 22 symmetry sets up between the adjacent emery stick 2. It should be noted that each sanding strip 2 adopts protruding section 21 and sunken section 22 to connect in turn each other and form the wave in proper order to protruding section 21 and sunken section 22 that correspond between the adjacent sanding strip 2 all set up symmetrically, make each sanding strip 2 projection have the overlap region on the horizontal plane, guaranteed like this that sanding strip 2 uses the product when on the surface, avoided sanding strip 2 to produce the motility blind area, thereby reach and polish more even effect with the product.

In one embodiment, the distance a between adjacent raised sections 21 of the same sanding bar 2 is: 5-20 mm. Referring to fig. 3, when the distance between the adjacent convex sections 21 of the same sanding strip 2 is less than 5mm, the sanding distance for the product is too small, and when the sanding strip 2 is repeatedly pulled to sand the surface of the product, the material consumption is easily increased, and the cost is increased; when the distance between the adjacent protruding sections 21 of the same sanding strip 2 is greater than 20mm, the sanding strip 2 needs to be pulled many times to polish the surface of the product, and the sanding efficiency is low.

In one embodiment, the polishing surface of the convex section 21 and the concave section 22 is provided with a plurality of resin-bonded abrasive mixtures arranged in sequence, wherein the resin-bonded abrasive mixture is one of corundum, silicon carbide and diamond. In this embodiment, a resin binder abrasive mixture, which may be grinding particles formed by one or more of corundum, silicon carbide, and diamond, is disposed on the grinding surfaces of the convex sections 21 and the concave sections 22, and the grinding effect can be improved by adding the grinding particles to grind the surface of a product. It should be noted that the polishing particles formed by the resin binder abrasive mixture may be arranged on the polishing surfaces of the concave portion and the convex portion in the same shape and size, or may be arranged on the polishing surfaces of the concave portion and the convex portion in different shapes and sizes, which is not limited herein.

In one embodiment, the substrate 1 is made of one of polyurethane elastic fiber, diene elastic fiber, polyetherester elastic fiber, composite elastic fiber, polyolefin elastic fiber, hard elastic fiber, cloth, PET, TPU, or PVC. It should be noted that, the substrate 1 is made of the above elastic material, so that when a product is polished, the extrusion force applied to the polishing strip 2 by the product is transmitted to the substrate 1, the extrusion force can be decomposed into the pressure in the vertical direction and the thrust in the horizontal direction, the pressure in the vertical direction is applied to the vertical direction of the substrate 1, so that the substrate 1 generates elastic shrinkage and plays a role of buffering, and the thrust in the horizontal direction is applied to the horizontal direction of the substrate 1, so that the substrate 1 is elastically stretched, thereby effectively preventing the polishing paper from being worn in the polishing process.

In one embodiment, the shape of the flutes 3 projected onto the surface of the substrate 1 is wavy. It should be noted that, because the grinding strips 2 are arranged in a wave shape, the chip grooves 3 formed between the adjacent grinding strips 2 are also in a wave shape, so that the waste chips can be conveniently and rapidly discharged from the chip grooves 3.

It is to be understood that the foregoing examples, while indicating the preferred embodiments of the utility model, are given by way of illustration and description, and are not to be construed as limiting the scope of the utility model; it should be noted that, for those skilled in the art, the above technical features can be freely combined, and several changes and modifications can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention; therefore, all equivalent changes and modifications made within the scope of the claims of the present invention should be covered by the claims of the present invention.
