Description
Technical field
The present invention relates to a kind of emery wheel, particularly relate to a kind of rubber sheet emery wheel and preparation method thereof.
Background technology
Many workpiece usually need be with the emery wheel finishing of polishing after technologies such as casting, welding, processing and maintenance are accomplished.Emery wheel is through bond countless tiny abrasive particles to be bonded together; Because abrasive particle is harder; Tack coat between the abrasive particle is very meagre, and causing the contact between abrasive particle almost is the rigidity contact, so emery wheel has higher rigidity, grinding capacity and grinding efficiency; But this emery wheel makes the surface of grinding workpiece be prone to produce cut, is difficult to obtain suface processing quality preferably.One Chinese patent application 200810049094.6 has proposed a kind of rubber elastic grinding wheel, has both had better hardness and toughness, have elasticity preferably again simultaneously, thereby improved the surface quality of grinding workpiece, but it still has disadvantage:
(1) hear resistance is relatively poor, goes up at grinding workpiece (product or raw material) easily and forms burn or oxidation aspect.
(2) resistance to water is relatively poor, and long-term contact wetting reduces the binding ability of emery wheel easily.
(3) corrosion resistance is relatively poor, contacts with alkaline solution for a long time, reduces the bond strength and the hardness of emery wheel easily.
(4) emery wheel loss when cutting is big, precision is lower.
(5) lack self-sharpening, service life is shorter, and operating efficiency is lower.
Summary of the invention
The purpose of this invention is to provide a kind of rubber sheet emery wheel and preparation method thereof, can effectively solve defectives such as existing emery wheel hear resistance is relatively poor, resistance to water is relatively poor, corrosion resistance is relatively poor, lack self-sharpening, loss is big when cutting, precision is lower.
