Problems solved by technology

The traditional ceramic material processing technology is mainly based on mechanical processing. By turning, cutting, and grinding ceramic materials, the process is simple and the efficiency is high. However, due to the high hardness and high brittleness of the ceramic material itself, mechanical processing is difficult to meet the requirements of the product. Requirements for high dimensional accuracy and low surface roughness
It is more difficult to meet the requirements of high dimensional accuracy and low surface roughness for superhard ceramics processed by traditional machining processes
[0003] So far, only the 3M company of the United States has developed a 45MIC diamond grinding pad for processing ceramics, but the 45MIC grinding pad of 3M company has poor flatness when processing superhard ceramic products, the surface quality of the product is not good, and the cutting efficiency is not high. The cost is high and the price is expensive. There are no high-efficiency, high-quality and low-cost superhard ceramic processing materials in China.

Embodiment 1

[0042] Such as figure 1 As shown, the present invention provides a diamond grinding pad for processing superhard ceramics, the grinding pad includes a diamond material layer 1 , and the diamond material layer 1 includes a square grinding block layer 11 and a flat layer 12 . From one side to the other side of the diamond grinding pad, it includes: square grinding block layer 11, flat layer 12, non-woven fabric layer 2, adhesive layer 3, PET film layer 4, PC with double-sided adhesive Ply 5. figure 1 Among them, 51 is the double-sided adhesive layer on the PC board layer with double-sided adhesive. The diamond material layer is made of the following raw materials by mass percentage, 35% of resin binder, 10% of diamond, 50% of wollastonite, 3% of molybdenum disulfide, and 2% of fumed silicon dioxide.

[0043] The above-mentioned preparation method for processing the diamond grinding pad of superhard ceramics comprises the following steps:

[0044] Step 1: Mixing: Weigh each ra...

Embodiment 2

[0056] The structure of the diamond grinding pad in embodiment 2 is the same as in embodiment 1, but the composition of preparing the diamond material layer is: resin binder 25%, diamond 20%, wollastonite 40%, molybdenum disulfide 10%, gas phase Silica 5%.

Embodiment 3

[0058] The structure of the diamond grinding pad in embodiment 3 is the same as in embodiment 1, but the composition of preparing the diamond material layer is: resin binder 50%, diamond 5%, wollastonite 43.5%, molybdenum disulfide 1%, gas phase Silica 0.5%.

Abstract

The invention provides a diamond grinding pad for processing super-hard ceramics. The grinding pad comprises a diamond material layer, wherein the diamond material layer comprises a square grinding block layer and a tiling layer and is prepared from the following raw materials in percentage by mass of 25 to 50 percent of resin binder, 5 to 20 percent of diamond, 1 to 10 percent of molybdenum disulfide, 20 to 50 percent of wollastonite and 0.5 to 5 percent of fumed silica. All of performances of the diamond grinding pad provided by the invention in the grinding force, the grinding force stability, the cutting force and the service life are remarkably superior to the performances of a 45MIC grinding pad of 3M company.

Description

technical field [0001] The invention relates to the field of research and development of ceramic processing devices, in particular to a diamond grinding pad for processing superhard ceramics and a preparation method thereof. Background technique [0002] Due to the characteristics of high strength, high hardness, high brittleness, wear resistance, high shear stress resistance and extremely low tensile stress resistance of the ceramic itself, it is difficult to process, and the processing cost is high, the efficiency is low, and the processing quality is low. not ideal. Superhard ceramics (generally zirconia ceramics used in the field of electronic devices) are more prominent in strength, hardness, and brittleness than ordinary ceramics, making it more difficult to process, and the processing cost is higher and the efficiency is lower. Therefore, The processing quality is even less ideal. With economic development putting forward higher demands on ceramic performance, super...
