Problems solved by technology

[0002] At present, the grinding treatment of domestic stainless steel usually adopts solid abrasive paste or mixed abrasive paste. The surface roughness of stainless steel treated by this type of abrasive is relatively high, which cannot meet the technical requirements of stainless steel parts for aero-engines.
Domestically produced stainless steel abrasives are used in a large amount when processing parts, and the cost performance is not high. At the same time, some abrasives will cause damage to the CNC grinding machine due to composition problems.

Embodiment 1

[0018] Add stearic acid to white corundum powder, mix well; then add beeswax, mix well; then add oleic acid, mix well; then add oleic acid, mix well; then add aviation gasoline, mix well; then add aviation kerosene, mix well Evenly; the mixing ratio is 19% by weight of white corundum, 4.5% of stearic acid, 0.5% of beeswax, 18% of oleic acid, 52% of aviation gasoline, and 6% of aviation kerosene.

[0019] Then it was placed at room temperature for 150 hours to obtain a mixed material.

[0020] The mixed material is kept at 200±5° C. for 10 hours, and then cooled to room temperature to prepare a liquid abrasive.

[0021] Use this liquid abrasive to process the end face sealing surface of the stainless steel sealing seat. The roughness of the processed sealing end face is Raδ≤Ra0.2, and the flatness is 0.0012. Using 1000 ml of this liquid abrasive can process 20 such workpieces, each The processing time of the workpiece is 10min.

[0022] Ordinary abrasive paste is used to proc...

Embodiment 2

[0024] Add stearic acid to white corundum powder, mix well, then add beeswax, mix well, then add oleic acid, mix well, then add oleic acid, mix well, then add aviation gasoline, mix well, then add aviation kerosene, mix Uniform; the mixing ratio is 20% by weight of white corundum, 3% of stearic acid, 1% of beeswax, 20% of oleic acid, 54% of aviation gasoline, and 2% of aviation kerosene.

[0025] Then it was placed at room temperature for 150 hours to obtain a mixed material.

[0026] The mixed material was kept at 200±5° C. for 11 hours, and then cooled to room temperature to prepare a liquid abrasive.

Embodiment 3

[0028] Add stearic acid to white corundum powder, mix well, then add beeswax, mix well, then add oleic acid, mix well, then add oleic acid, mix well, then add aviation gasoline, mix well, then add aviation kerosene, mix Uniform; mixing ratio by weight percentage is that white corundum accounts for 21%, stearic acid accounts for 3%, beeswax accounts for 1%, oleic acid accounts for 20%, aviation gasoline accounts for 57%, and aviation kerosene accounts for 6%.

[0029] Then keep the temperature at 40° C. for 20 h; obtain the mixed material.

[0030] The mixed material is kept at 200±5° C. for 12 hours, and then cooled to room temperature to prepare a liquid abrasive.

Abstract

The invention provides liquid abradant and a preparation method thereof, which belongs to the technical field of materials. The components in weight percentage of the liquid abradant are: 19 to 21 percent of white alundum powder, 3 to 5 percent of stearic acid, 0.5 to 1.5 percent of beeswax, 10 to 20 percent of oleic acid, 52 to 57 percent of aviation gasoline and 2 to 6 percent of aviation kerosene. The preparation method comprises the following steps of mixing the white alundum powder, the stearic acid, the beeswax, the oleic acid, the aviation gasoline and the aviation kerosene so as to obtain a mixed material; preserving the heat of the mixed material for 10 to 12 hours at a temperature of 200+-5 DEG C, cooling the mixed material to room temperature and preparing the mixed material into the liquid abradant. The liquid abradant with the same volume has the advantages of large processing quantity and short processing time. The liquid abradant prepared by the invention is convenient to use and little in harm to equipment, and has good application prospects.

Description

technical field [0001] The invention belongs to the field of aviation technology, in particular to a liquid abrasive and a preparation method thereof. Background technique [0002] At present, the grinding treatment of domestic stainless steel usually adopts solid abrasive paste or mixed state abrasive paste. The surface roughness of stainless steel treated by this type of abrasive is relatively high, which cannot meet the technical requirements of stainless steel parts for aero-engines. Domestically produced stainless steel abrasives are used in a large amount when processing parts, and the cost performance is not high. At the same time, some abrasives will cause damage to the CNC grinding machine due to composition problems. [0003] Therefore, the development of a liquid abrasive that can grind stainless steel to a lower surface roughness has become an urgent problem to be solved. Contents of the invention [0004] In view of the above technical problems, the present i...
