Abstract

The invention discloses a thermoplastic abrasive for polishing a hard alloy and a manufacture method thereof. The abrasive is prepared from the following components in parts by weight: 60-80 parts ofabrasive, 19-35 parts of thermoplastic polymer, 0.1-1.5 parts of dispersing agent, 0.1-1 part of lubricant, 0.1-1.5 parts of antioxidant, 0.6-2.4 parts of coupling agent, and 60-240 parts of industrial alcohol. The abrasive is prepared through the process of internal mixing-pelletizing. The abrasive has high cutting performance, good wear resistance and high toughness, prevents workpieces from pitdamage and scratch, fails to break the hard alloy, and is easy to clean. The thermoplastic abrasive is easy to prepare, can be produced efficiently in a short production cycle, is environmentally friendly, and can be recycled for many times.

Description

Technical field: [0001] The invention relates to a thermoplastic abrasive for hard alloy polishing and a production method thereof, belonging to the technical field of polishing materials and grinding tools. Background technique: [0002] Existing abrasives used in the polishing field are divided into natural abrasives and artificial abrasives according to their materials and manufacturing methods, wherein natural abrasives such as pebbles, white stones, quartz sand, artificial abrasives can also be divided into organic abrasives and inorganic abrasives, organic abrasives such as Leather, fruit shells, wood chips, etc., inorganic abrasives such as oxides, carbides, metal steel, corundum, resin abrasives, etc. The advantage of natural abrasive is that it is easy to mine and cheap, but its grinding performance is single and its polishing quality is low. Artificial organic abrasives are suitable for polishing soft workpieces, but are not strong enough for hard alloy grinding, ...
