Abstract

The invention relates to a rubber binding agent, a preparing method of the rubber binding agent, a super-hard grinding wheel and a preparing method of the super-hard grinding wheel, and belongs to the technical field of grinding materials and grinding tools. The rubber binding agent is made of following raw materials including, by weight, 100 parts of vinyl silicone rubber, 40-60 parts of carbon black, 3-6 parts of DPSD, 4-8 parts of zinc stearate and 2-3 parts of hydroxyl-fluoro silicone oil. The characters of high strength, low hardness and the like of the vinyl silicone rubber are utilized, the grinding wheel prepared through the rubber binding agent has the beneficial effects that the strength is high, tenacity is good, a grinding tool structure is compact and porosity is small, the grinding wheel can be used for fine grinding, polishing, cutting and other machining of stainless steel, an aluminum alloy, a nickel alloy, tool steel and other metal, and the surface quality of obtained workpieces is good. The rubber binding agent is low in forming temperature; and after forming, high temperature resistance and acid-base resistance are achieved, the rubber binding agent is suitable for multiple grinding materials, the grinding material holding force is good, and universality is achieved.

Description

technical field [0001] The invention relates to a rubber bond and a preparation method thereof, a superhard grinding wheel and a preparation method thereof, and belongs to the technical field of abrasives and abrasive tools. Background technique [0002] Superhard material abrasives are widely used in the field of machining, such as machining in automobile, electronics, refrigeration, tools, LED and other industries. Superhard material abrasives, especially diamond and cubic boron nitride bonded grinding wheels, occupy a dominant position in the current grinding technology. Superhard material grinding wheels are made by adding a bond to the abrasive, and then compacting, drying and roasting. formed porous body. The characteristics of superhard material grinding wheels are mainly determined by factors such as abrasives, particle size, binder, hardness, structure, shape and size. At present, the commonly used bonding agents for superhard material wheels include metal bonding...
