Abstract

The invention provides a grinding agent for ceramic materials. The abrasive for ceramic materials contains a film-forming agent, an auxiliary film-forming agent, abrasive particles, and water. The film-forming agent is selected from one or both of lower polyols and alcohol amines. The lower polyols are polyols with 2 to 5 carbon atoms and two or more hydroxyl groups in their molecules. The auxiliary film-forming agent is selected from one or both of borate and lithium chromate, and the abrasive particles are boride. The mass ratio among the film-forming agent, auxiliary film-forming agent, grinding particles and water is 10-30:0.2-4:0.1-3:70-90. The abrasive has an excellent grinding effect, is suitable for extreme pressure environments, and is environmentally friendly.

Description

technical field

[0001] The invention relates to an abrasive for ceramic materials, in particular to a water-based abrasive for ceramic materials with excellent grinding effect, suitable for extreme pressure environments and environmental protection. Background technique

[0002] Ceramic materials have the advantages of high melting point, high hardness, high wear resistance, and oxidation resistance. In the machinery industry, more and more wearable parts such as seals, bearings, ball valves, and cylinder liners are made of ceramic materials. Due to the special physical and mechanical properties of ceramic materials, grinding methods are mainly used to process them. Grinding process occupies a very important proportion in the grinding method, and this link has an important impact on the processing efficiency and processing quality of ceramic material parts. During the grinding process, the grinding disc or grinding ball and the workpiece to be processed rub against each oth...

Embodiment Construction

[0017] The abrasives for ceramic materials of the present application will be described in detail below through specific examples. It should be noted that the examples are only used to illustrate the composition, content and preparation method of the abrasive, and do not limit the protection scope of the present application in any way.

[0018] The abrasive for ceramic materials described in the present application contains a film-forming agent, an auxiliary film-forming agent, abrasive particles, and water. The film forming agent is selected from one or both of lower polyols and alcohol amines, the auxiliary film forming agent is selected from one or both of borate and lithium chromate, and the abrasive particles for borides. The mass ratio among the film-forming agent, auxiliary film-forming agent, grinding particles and water is 10-30:0.2-4:0.1-3:70-90. Preferably, the mass ratio between the film-forming agent, auxiliary film-forming agent, abrasive particles and water is...
