Embodiment 1

[0035] The schematic diagram of the structure of the diamond brushed sheet is shown in Figure 1, including a grinding layer 1, a substrate 2 and a cloth base 3, the grinding layer 1 is attached to the base body 2 by electroplating, the base body 2 is bonded to the front of the cloth base 3, and the back of the cloth base 3 is planted. There are fluff 4, and the grinding layer 1 is composed of nickel-diamond composite electroplating layers 5 evenly spaced. Its preparation method is as follows:

[0036] The 200-325 mesh wire mesh (substrate 2) is electroplated in the nickel-diamond electroplating solution to form a silver-white nickel-diamond composite electroplating layer 5, and the nickel-diamond composite electroplating layer 5 is evenly spaced to form the grinding layer 1. The layer is attached to a wire mesh (substrate 2), the content of diamond in abrasive layer 1 is 11 wt%.

[0037] After washing and drying, apply epoxy resin evenly on the front of the man-made fiber clo...

Embodiment 2

[0041] The 200-325 mesh wire mesh is electroplated in the nickel-diamond electroplating solution to form a silver-white nickel-diamond composite electroplating layer. The nickel-diamond composite electroplating layer is evenly spaced to form a grinding layer, and the grinding layer is attached to the wire mesh. The content of diamond in the grinding layer is 9wt%.

[0042] After washing and drying, apply epoxy resin evenly on the front of the man-made fiber cloth base, bond the non-plated surface of the wire mesh with the front of the cloth base, and then dry and cure in a curing kiln. The drying temperature is 80°C and the time is 1h, the curing temperature is 120°C, and the curing time is 2h.

[0043] Plant red fluff on the back of the cloth base to make a brushed cloth embryo.

[0044] It is punched out by a punching machine into a round brushed sheet with a diameter of 100 mm and a hole in the middle with a diameter of 16 mm.

Embodiment 3

[0046] The 200-325 mesh wire mesh is electroplated in the nickel-diamond electroplating solution to form a silver-white nickel-diamond composite electroplating layer. The nickel-diamond composite electroplating layer is evenly spaced to form a grinding layer, and the grinding layer is attached to the wire mesh. The content of diamond in the grinding layer is 10wt%.

[0047] After washing and drying, apply epoxy resin evenly on the front of the man-made fiber cloth base, bond the non-plated surface of the wire mesh with the front of the cloth base, and then dry and cure in a curing kiln. The drying temperature is 80°C and the time is 1h, the curing temperature is 120°C, and the curing time is 2h.

[0048] Plant green fluff on the back of the cloth base to make a brushed cloth embryo.

[0049] It is punched into an equilateral triangle brushed sheet with a side length of 80 mm through a punching machine.

Abstract

The invention belongs to the field of coated abrasive tools, and discloses a diamond brushed piece. The diamond brushed piece comprises a grinding layer, a base body and a fabric base, wherein the grinding layer contains diamond and adheres to the base body through electroplating; the base body adheres to the front face of the fabric base; and fluff is grown on the back face of the fabric base. The invention further discloses a preparation method of the diamond brushed piece. The diamond brushed piece is good in deflection, machining property and sharpness, long in service life, and suitable for grinding of various materials.

Description

technical field [0001] The invention belongs to the field of coated abrasives, and relates to a diamond brushed sheet and a preparation method thereof. Background technique [0002] As a modern industrial tool, coated abrasives have good grinding, fine grinding, and polishing performances. They are convenient and safe to use; they have large grinding areas and high efficiency; they are widely used. The abrasives of coated abrasives in the early stage are mainly traditional corundum and silicon carbide. When processing difficult-to-machine materials such as hard and brittle and hard and ductile, they have the disadvantages of fast wear, low processing accuracy and low processing efficiency. With the rapid development of my country's metallurgical industry and modern mechanical processing industry, various new materials continue to appear, high-end equipment manufacturing has higher and higher requirements for processing accuracy and surface finish, and coated abrasives are al...
