Description

Technical Field

[0001] The invention relates to a diamond tower-shaped sandpaper. Background Art

[0002] Coated abrasives are made by bonding abrasives to some flexible materials such as cloth and paper with a binder. They are a kind of tool that can be used for grinding and polishing. The three main materials for making coated abrasives are substrate, abrasive and binder. Traditional coated abrasives generally use cloth or paper as the substrate. The substrate is the carrier of abrasives and binders, and it is the dominant factor in the flexibility of coated abrasives. The types of substrates mainly include: cloth, paper, fiber, non-woven fabrics, etc. The binder includes base glue and over-glue, which firmly bonds the abrasive to the substrate. Sandpaper used for grinding is one of the coated abrasives. The user can fix the sandpaper on the movable mechanism and let the movable mechanism drive the sandpaper to grind.

[0003] The existing diamond sandpaper has poor grinding effect and low efficiency. Summary of the invention

[0004] In order to overcome the shortcomings and deficiencies of the prior art, the present invention discloses a diamond tower-shaped sandpaper, comprising a substrate layer, a bonding layer and an abrasive layer, wherein the bonding layer is composed of a base glue layer and a double glue layer coated on the base glue layer, and the abrasive layer is fixed to the top surface of the substrate layer through the bonding layer; the abrasive layer comprises a grinding tower and a transition groove, wherein the grinding tower is composed of a plurality of stacked abrasive sheets, and the width of the abrasive sheet located in the upper layer is smaller than the width of the abrasive sheet located in the lower layer; the cross-section of the transition groove is wavy; and the transition groove is arranged between a plurality of the grinding towers.

[0005] As a further improvement of the present invention, the abrasive sheet of the grinding tower is composed of silicon carbide particles.

[0006] As a further improvement of the present invention, the substrate layer is latex paper.

[0007] As a further improvement of the present invention, a mounting buckle is provided on the bottom surface of the substrate layer.

[0008] As a further improvement of the present invention, the mounting buckle is an arc-shaped metal sheet, both ends of which are fixed to the bottom surface of the substrate layer.

[0009] As a further improvement of the present invention, the surface of the arc-shaped metal sheet is provided with anti-slip grooves.

[0010] As a further improvement of the present invention, the width of the arc-shaped metal sheet gradually decreases from the outside to the inside.

[0011] The diamond tower-shaped sandpaper of the invention has good grinding effect and high grinding efficiency and is convenient to fix during use.

[0012] For better understanding and implementation, the present invention is described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a schematic diagram of the present invention.

[0014] Figure 2 It is a bottom view of the substrate layer. DETAILED DESCRIPTION

[0015] See also Figure 1 and 2 The present invention discloses a diamond tower-shaped sandpaper, comprising a substrate layer 10, a bonding layer and an abrasive layer, wherein the bonding layer is composed of a base glue layer 21 and a double glue layer 22 coated on the base glue layer 21, and the abrasive layer is fixed to the top surface of the substrate layer 10 through the bonding layer; the abrasive layer comprises a grinding tower 31 and a transition groove 32, wherein the grinding tower 31 is composed of a plurality of stacked abrasive sheets 311, wherein the width of the abrasive sheet 311 located in the upper layer is smaller than the width of the abrasive sheet 311 located in the lower layer; the cross section of the transition groove 32 is wavy; and the transition groove 32 is arranged between a plurality of the grinding towers 31.

[0016] The abrasive sheet 311 of the grinding tower 31 is composed of silicon carbide particles. The substrate layer 10 is latex paper. The bottom surface of the substrate layer 10 is provided with a mounting buckle 11. The mounting buckle 11 is an arc-shaped metal sheet, and its two ends are fixed to the bottom surface of the substrate layer 10. The surface of the arc-shaped metal sheet is provided with anti-slip grooves. The width of the arc-shaped metal sheet gradually decreases from the outside to the inside, and such a setting can make the fixing of the movable mechanism more stable after insertion.

[0017] The grinding tower 31 can grind and polish the surface of the workpiece, and the transition groove 32 can grind the uneven parts of the workpiece surface quickly. The mounting buckle 11 is convenient for the user to fix the sandpaper on the movable mechanism.

[0018] The diamond tower-shaped sandpaper of the invention has good grinding effect and high grinding efficiency and is convenient to fix during use.

[0019] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the scope of the claims and equivalent technologies of the present invention, the present invention is also intended to include these changes and modifications.
