Background technology
At present, most domestic glass, the attrition process of ceramics are to use the free type that Brown Alundum is added in cooling water
The problems such as stock-removing efficiency is low, converted products yield is low, rear process is difficult be present in grinding technics, this technique.Minnesota Mining and Manufacturing Company
The grinding pad roughly ground and refined for glass is successfully developed, stock-removing efficiency is high, converted products yield is high, but grinding pad kind list
One, it is impossible to meet that different product and grinding process are required grinding cutting force and the different of product surface roughness.
Lens Technology Co., Ltd. discloses a kind of epoxy resin type diamond grinding pad and preparation method thereof, and (this is special
Profit is also in publicity), but do not pay close attention to the grinding cutting force of grinding pad and the regulation problem of product surface roughness.
The content of the invention
Present invention aims at a kind of composition, method and mould for adjusting grinding pad grinding cutting force is provided, to solve
Current grinding pad can not according to the actual requirements, the technology that the grinding cutting force scope to demand in preparation process is adjusted
Problem.
To achieve the above object, the invention provides a kind of method for adjusting grinding pad grinding cutting force, in resin abrasive tools
Raw material in add aerosil, the raw material of resin abrasive tools includes abrasive material, resin and auxiliary agent, the aerosil
Specific surface area is 50~400m2/ g, addition are the 0.5~2% of raw material gross weight.
Preferably, the abrasive size is 5~100 μm.
Preferably, the abrasive material is diamond, and diamond average grain diameter is 10-60 μm.
Preferably, diamond addition is 10-25wt%.
Preferably, the resin content is 40-50wt%.
Preferably, the addition of the aerosil is 0.02-0.2 times of diamond weight added in grinding tool.
Preferably, the resin includes epoxy resin, phenolic resin, polyurethane and corresponding all kinds of modified resins.
The invention provides a kind of composition for adjusting grinding pad grinding cutting force, including abrasive material, resin and gas phase dioxy
SiClx, the specific surface area of the aerosil is 50~400m2/ g, addition are the 0.5~2% of composition total weight.
The invention provides a kind of resin abrasive tools, raw material includes abrasive material, resin and aerosil, the gas phase dioxy
The specific surface area of SiClx is 50~400m2/ g, addition are the 0.5~2% of raw material gross weight.
The invention has the advantages that：
The present invention uses cutting force conditioning agent of the aerosil as resin abrasive tools, can effectively adjust grinding cutting
Power and product surface roughness, it is widely used in the grinding tool of various resinoids and abrasive material, meets the production of different product and process
It is required that.
Inventor has found, when specific surface area is identical, with the content increase of aerosil, cutting force reduces, production
The surface roughness increase of product；When content is identical, with the specific surface area increase of aerosil, cutting force increase, production
The surface roughness of product reduces.Therefore, in actual production process, can select to reduce or increase cutting force according to the actual requirements,
Change the surface roughness of product therewith.
Aerosil adds in dispensing, if addition is very little, the influence to cutting force is small, and thickening power
Unobvious, it is impossible to effectively prevent the sedimentation of diamond；Addition is excessive, and thickening power is too strong, is unfavorable for mold filling, by inventor
Many experiments, addition is 0.5~2% more suitable for raw material gross weight.
The adjacent aggregation of nano grade gas phase silicon dioxide of the present invention is formed well-regulated by Hydrogenbond
Network structure, there is thickening power, addition is more, and thickening power is more obvious, can effectively reduce because in grinding pad production process
The problem of cutting force caused by diamond sedimentation is unstable；When plus shearing force, a part of hydrogen bond destroys, and viscosity reduces,
Therefore the addition of aerosil can't cause filler difficulty big.
In addition, aerosil belongs to cheap convenient source, source is wide, and cost is low, can meet industrialized production.
In addition to objects, features and advantages described above, the present invention also has other objects, features and advantages.
The present invention is further detailed explanation below.
