Description

Technical Field

[0001] The utility model relates to the technical field of sandpaper production, in particular to an aluminum oxide sandpaper with a wear-resistant coating. Background Art

[0002] Alumina sandpaper is a type of sandpaper with aluminum oxide particles as abrasives, which is usually used for surface grinding and polishing of materials such as metal, wood, and plastic. Alumina particles have the characteristics of high hardness, wear resistance, and good chemical stability, so they are widely used in sandpaper manufacturing. The basic steps for making aluminum oxide sandpaper are as follows: 1) Prepare the substrate: Select a suitable substrate, such as paper, cloth, etc., and cut and process it as needed; 2) Glue coating: Apply an appropriate amount of glue on the substrate to adhere the aluminum oxide particles to the substrate. 3) Sanding: Sprinkle the aluminum oxide particles evenly on the substrate coated with glue to ensure that the particles are evenly distributed. 4) Hot pressing: The sanded substrate is hot pressed to make it tightly bonded to the substrate. 5) Drying: Dry the hot pressed sandpaper to remove excess moisture and glue. 6) Cutting: Cut the dried sandpaper into appropriate sizes and shapes as needed. It should be noted that the process of making aluminum oxide sandpaper requires precise control of various parameters, such as the particle size of aluminum oxide particles, the thickness of the glue coating, the temperature of hot pressing, etc., to ensure the quality and performance of the sandpaper.

[0003] The traditional aluminum oxide sandpaper still has some shortcomings when used. First, its wear-resistant coating is not provided with chip removal grooves, which makes it difficult to remove chips during the grinding process; second, its wear-resistant coating is always exposed, which is easy to be damaged during transportation and storage. Therefore, it is necessary to optimize and improve its structure. Utility Model Content

[0004] The utility model aims to overcome the above problems existing in the traditional technology and provide an aluminum oxide grinding paper with a wear-resistant coating.

[0005] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0006] Aluminum oxide sandpaper with a wear-resistant coating comprises a sandpaper body, a pre-pressed fold is provided in the middle of the sandpaper body, and the sandpaper body is divided into a first tough base paper and a second tough base paper by the pre-pressed fold, a first meandering spiral wear-resistant coating is provided on the inner side of the first tough base paper, a first meandering spiral chip groove is provided inside the first meandering spiral wear-resistant coating, a second meandering spiral wear-resistant coating is provided on the inner side of the second tough base paper, a second meandering spiral chip groove is provided inside the second meandering spiral wear-resistant coating, and after the first tough base paper and the second tough base paper are folded relative to each other about the pre-pressed fold, the second meandering spiral wear-resistant coating of the second tough base paper can just fit into the first meandering spiral chip groove of the first tough base paper.

[0007] Furthermore, in the above-mentioned aluminum oxide sandpaper with wear-resistant coating, the widths of the first meandering spiral wear-resistant coating and the second meandering spiral wear-resistant coating are equal at all locations, and the width is 1-2 cm.

[0008] Furthermore, in the above-mentioned alumina sandpaper with wear-resistant coating, the groove width of the first meandering spiral chip groove is equal to the width of the first meandering spiral wear-resistant coating, and the groove width of the second meandering spiral chip groove is equal to the width of the second meandering spiral wear-resistant coating.

[0009] Furthermore, in the above-mentioned alumina sandpaper with wear-resistant coating, the density of the alumina ceramic abrasives in each location of the first meander-shaped spiral wear-resistant coating and the second meander-shaped spiral wear-resistant coating is equal.

[0010] Furthermore, in the above-mentioned aluminum oxide sandpaper with wear-resistant coating, chip removal holes penetrating the tough base paper are evenly opened in the first zigzag spiral chip removal groove and the second zigzag spiral chip removal groove.

[0011] Furthermore, in the above-mentioned aluminum oxide sandpaper with wear-resistant coating, the hole shape of the chip removal holes is one of circular, square and triangular.

[0012] The beneficial effects of the utility model are:

[0013] 1. The sandpaper body is divided into two parts by the pre-pressed fold, one of which is composed of the first tough base paper, the first meandering spiral wear-resistant coating and the first meandering spiral chip groove, and the other is composed of the second tough base paper, the second meandering spiral wear-resistant coating and the second meandering spiral chip groove. When in use, the first tough base paper and the second tough base paper can be folded relative to each other about the pre-pressed fold, so that the second meandering spiral wear-resistant coating of the second tough base paper can just be inserted into the first meandering spiral chip groove of the first tough base paper. In this way, the wear-resistant coating can be prevented from being exposed all the time, and it is not easy to be damaged during transportation and storage; at the same time, the design of the first meandering spiral chip groove and the second meandering spiral chip groove is conducive to chip removal during the use of the sandpaper.

[0014] 2. Chip removal holes are added in the first and second zigzag spiral chip removal grooves, and the automatic chip removal can be realized during the use of the sandpaper by cooperating with the negative pressure dust suction channel in the fixture.

[0015] Of course, any product implementing the present invention does not necessarily need to achieve all of the above advantages at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
