[0019] Polystyrene: 30 parts Plasticizer dioctyl phthalate DOP: 10 parts

[0020] Methyl silicone rubber: 70 parts Methyl silicone oil: 10 parts

[0021] Diamond abrasive grains: 100 parts.

[0022] The preparation process of the high-hardness viscoelastic abrasive material of the present invention is as follows: adding polystyrene into the reaction kettle, starting stirring, heating and raising to 150~180°C; adding plasticizer dioctyl phthalate, stirri...

Embodiment 2

[0024] The principle of the second embodiment is the same as that of the first embodiment, except that the composition and proportion of the high-hardness viscoelastic abrasive of the present invention are as follows (proportioned by weight):

[0025] Polystyrene: 30 parts Plasticizer dioctyl phthalate: 10 parts

[0026] Ethyl silicone rubber: 20 parts Phenyl silicone rubber: 50 parts

[0027] Methyl silicone oil: 20 parts Diamond abrasive grains: 80 parts.

[0028] The preparation process of the high-hardness viscoelastic abrasive material of the present invention is as follows: adding polystyrene into the reaction kettle, starting stirring, heating and raising to 150~180°C; adding plasticizer dioctyl phthalate, stirring for 0.5~2h; Cool down, add ethyl silicone rubber, phenyl silicone rubber and methyl silicone oil, mix and stir for 1~2h; add diamond abrasive grains, mix and stir for 0.5~2h; discharge and pack.

Embodiment 3

[0030] The principle of the third embodiment is the same as that of the first embodiment, except that the composition and proportion of the high-hardness viscoelastic abrasive of the present invention are as follows (proportioned by weight):

[0031] Polystyrene: 50 parts Plasticizer dioctyl phthalate: 30 parts

[0032] Phenyl silicone rubber: 50 parts Methyl silicone oil: 10 parts

[0033] Cubic boron nitride abrasive particles: 80 parts.

[0034] The preparation process of the high-hardness viscoelastic abrasive material of the present invention is as follows: adding polystyrene into the reaction kettle, starting stirring, heating and raising to 150~180°C; adding plasticizer dioctyl phthalate, stirring for 0.5~2h; Cool down, add phenyl silicone rubber and methyl silicone oil, mix and stir for 1~2h; add cubic boron nitride abrasive grains, mix and stir for 0.5~2h; discharge and pack.

Abstract

The invention discloses a preparation method of a high-hardness viscoelastic abrasive material and a product for a special honing machine, and belongs to the technical field of abrasive material manufacturing. The high-hardness viscoelastic abrasive material comprises the following components in parts by weight: 30-50 parts of polystyrene, 10-30 parts of plasticizer dioctyl phthalate, 50-70 parts of silicone rubber, 5-30 parts of ploydimethylsilicon oil and 80-120 parts of abrasive grains. The high-hardness viscoelastic abrasive material provided by the invention has liquidity and elasticity, and can be used by a special honing machine to hone a super-hard complex surface of a workpiece into a misty mirror with Ra=0.012 [mu] m, which cannot be achieved with the conventional machine tool technologies.

Description

Technical field [0001] The invention belongs to the technical field of abrasive manufacturing, and specifically relates to a preparation method for preparing high-hardness viscoelastic abrasives specially for special honing machine tools, and is used for honing high-hardness and complex surface workpieces. Background technique [0002] With the development of the aerospace industry, precision instrument industry, optical electronics industry and modern machinery industry, the production of complex surface parts with superhard materials has become a trend, such as various tool steels, titanium alloys and silicon carbide. Moreover, there are almost strict requirements on machining accuracy and surface roughness, and the existing machine tool technology is difficult to meet the requirements. [0003] The high-hardness viscoelastic abrasive of the present invention is designed to provide special honing medium abrasives for special honing machine tools, which can honing the surface of s...
