Problems solved by technology

[0007] 1. The toughness and strength of the sand disc cannot maintain consistency, and it is prone to accidents caused by debris during high-speed grinding
[0008] 2. The substrate and the abrasive layer cannot be ground synchronously during high-speed grinding, and the grinding effect is poor
[0009] 3. The substrate prepared by steel paper or glass fiber mesh has high hardness and low elasticity. The product will damage the workpiece when it is used, and the glass fiber mesh will fly out of the glass fiber when it is polished, causing damage to human skin, which is not enough. Environmental friendly

Embodiment 1

[0023] Example 1, see figure 1 Shown: Grid bonded sanding disc, including bonded paper 20. Specifically, the upper surface of the steel paper 20 is bonded with the first abrasive layer 10 by materials such as resin, and the lower surface of the steel paper 20 is bonded with linen or cotton cloth mesh 40 by materials such as resin. The burlap or cotton mesh 40 refers to a burlap mesh or a cotton mesh, wherein the burlap mesh refers to a web made of hemp, flax, ramie, jute, sisal, abaca and other hemp plant fiber materials. Grid, cotton grid refers to the grid made of common cotton spinning materials. That is, the grid steel paper sanding disc is optimized for the order of the common abrasive layer, steel paper, and grid layer, so that the grid layer is located behind the steel paper. In this way, the grid steel paper sanding disc fully exerts the toughness and strength of the steel paper 20, so that the grid steel paper sanding disc has good toughness and strength, and ensure...

Embodiment 2

[0025] Example 2, see figure 2 Shown: on the basis of Embodiment 1, a second abrasive layer 30 is bonded between the steel paper 20 and the linen or cotton grid 40 . In this way, the use cost of the grid steel paper sanding disc is reduced.

[0026] The preparation of grid steel paper sand disc of the present invention can comprise the following steps:

[0027] 1. Use the automatic assembly line to glue and plant sand on the steel paper with materials such as resin, and form the first abrasive layer on the upper surface of the steel paper to make a steel paper sand roll.

[0028] 2. Punch and cut steel paper sand rolls into steel paper sand discs according to requirements.

[0029] 3. Apply glue evenly on the back of the punched steel paper sand disc.

[0030] 4. Glue and sand the washed linen or cotton grid.

[0031] 5. Bond the glue on the back of the steel paper with the linen or cotton mesh disc, press it into the oven for curing and forming.

Abstract

The invention discloses a grid vulcanized fiber paper sand tray which comprises vulcanized fiber paper. The upper surface of the vulcanized fiber paper is adhered with a first grinding material layer, and the lower surface of the vulcanized fiber paper is adhered with linen or a cotton grid. After optimizing, a second grind material layer is adhered between the vulcanized fiber paper and the linen or the cotton grid. The grid vulcanized fiber paper sand tray has the advantages that toughness and intensity of the sand tray can retain accordance well, synchronism of grinding is good, elasticity of products is good and using cost of the products is low.

Description

technical field [0001] The invention relates to the technical field of grinding tools, in particular to a grid steel paper sanding disc. Background technique [0002] A sanding disc is the most common tool used in sanding operations. Usually, the preparation process of the sand tray mainly has the following types: [0003] 1. Steel paper is used as the substrate, and the abrasive layer is bonded with resin on the surface of the substrate. [0004] 2. Using steel paper as the substrate, an abrasive layer is bonded with resin on the surface of the substrate, and a layer of glass fiber grid is bonded with resin between the substrate and the abrasive layer. [0005] 3. The glass fiber grid is used as the matrix, and the abrasive layer is bonded with resin on the matrix. [0006] The sand trays produced by the above several processes have the following defects: [0007] 1. The toughness and strength of the sand disc cannot maintain consistency, and it is prone to accidents ca...
