Lens Technology Co., Ltd. discloses a kind of epoxide resin type diamond lap pad and preparation method thereof (this patent is also in publicity), but does not pay close attention to the grinding cutting force of grinding pad and the adjustment problem of product surface roughness.
Summary of the invention
The object of the invention is to provide a kind of composition, method and the mould that regulate grinding pad grinding cutting force, can not according to the actual requirements to solve current grinding pad, to the technical problem that the grinding cutting force scope of demand regulates in preparation process.
For achieving the above object, the invention provides a kind of method regulating grinding pad grinding cutting force, in the raw material of resin abrasive tools, add aerosil, the raw material of resin abrasive tools comprises abrasive material, resin and auxiliary agent, and the specific area of described aerosil is 50 ~ 400m
2/ g, addition is 0.5 ~ 2% of raw material gross weight.
Preferably, described abrasive size is 5 ~ 100 μm.
Preferably, described abrasive material is diamond, and diamond average grain diameter is 10-60 μm.
Preferably, diamond addition is 10-25wt%.
Preferably, described resin content is 40-50wt%.
Preferably, the addition of described aerosil is 0.02-0.2 times of the diamond weight of adding in grinding tool.
Preferably, described resin comprises epoxy resin, phenolic resins, polyurethane and corresponding all kinds of modified resin.
The invention provides a kind of composition regulating grinding pad grinding cutting force, comprise abrasive material, resin and aerosil, the specific area of described aerosil is 50 ~ 400m
2/ g, addition is 0.5 ~ 2% of composition total weight.
The invention provides a kind of resin abrasive tools, raw material comprises abrasive material, resin and aerosil, and the specific area of described aerosil is 50 ~ 400m
2/ g, addition is 0.5 ~ 2% of raw material gross weight.
The present invention has following beneficial effect:
The present invention adopts aerosil as the cutting force conditioning agent of resin abrasive tools, effectively can regulate grinding cutting force and product surface roughness, be widely used in the grinding tool of various types of resin and abrasive material, meet the production requirement of different product and operation.
Inventor finds, when specific area is identical, along with the content of aerosil increases, cutting force reduces, and the surface roughness of product increases; When content is identical, along with the specific area of aerosil increases, cutting force increases, and the surface roughness of product reduces.Therefore, in actual production process, can select according to the actual requirements to reduce or increase cutting force, change the surface roughness of product thereupon.
Aerosil adds when preparing burden, if addition very little, little on the impact of cutting force, and thickening power is not obvious, can not effectively stop adamantine sedimentation; Addition is too much, and thickening power is too strong, is unfavorable for mold filling, and through the many experiments of inventor, addition is the 0.5 ~ 2% comparatively suitable of raw material gross weight.
The adjacent aggregation of nano grade gas phase silicon dioxide of the present invention passes through Hydrogenbond, form well-regulated network structure, there is thickening power, addition is more, thickening power is more obvious, effectively can reduce the problem of the cutting force instability caused because of diamond sedimentation in grinding pad production process; When adding up cut shear, a part of hydrogen bond destroys, and viscosity reduces, and therefore filler difficulty can't be caused large adding of aerosil.
In addition, aerosil belongs to cheap convenient source, and source is wide, and cost is low, can meet suitability for industrialized production.
Except object described above, feature and advantage, the present invention also has other object, feature and advantage.The present invention is further detailed explanation below.
