Description
Technical field
The present invention relates to a kind of preparation methods of rubber grinding tool.
Background technique
Hard brittle material such as sapphire, monocrystalline silicon carbide and engineering ceramics etc. are because having good chemical stability, wear-resisting
Property, thermal stability, low electric conductivity and higher hardness and strength, and be widely used in machine-building, auto industry, space flight boat
The fields such as sky, national defence, petrochemical industry and life.But due to these hard brittle materials hardness with higher and brittleness, so that its
It is machined extremely difficult.If processing method and processing technology selection are inappropriate, not only processing efficiency is low, machined surface quality
Also poor, the defects of being particularly susceptible generation a large amount of broken, crackle, makes poor reliability, the strength reduction of part, seriously affected it
Service performance.There is scholar to propose using grinding tool flexible thus to process it, avoid in process engineering workpiece surface broken and
The generation of the defects of crackle, to improve the surface quality of workpieces processing.
Rubber grinding tool is a kind of typical flexible grinding and polishing tool, its main feature is that abrasive grain is added in rubber matrix,
And mixed by certain way, so that abrasive grain is uniformly distributed.The advantages of rubber grinding tool, is that it has preferable elasticity, so that plus
The defects of being also easy to produce broken, crackle and scratching is not allowed during work, can obtain preferable surface quality.But due to abrasive grain and rubber
Combination between matrix body is acted on merely by mechanic coating of the rubber to abrasive grain, and the binding force between abrasive grain and rubber matrix is very
Weak, abrasive grain is easy to fall off in process, so that grinding tool cutting ability is deteriorated, influences processing efficiency.
Summary of the invention
The purpose of the present invention is to provide a kind of preparation methods of rubber grinding tool, solve mill during existing finishing
Easy to fall off, the big problem of workpieces processing surface damage of grain.
In order to solve the above-mentioned technical problems, the present invention provides a kind of preparation methods of rubber grinding tool, comprising the following steps:
(1) abrasive grain is added in liquid resin and is stirred evenly, curing agent or heating, which is then added, makes its solidification；
(2) resin after solidifying in step (1) is crushed；The resin is set to form the resin with certain diameter
Grain, the resin particle contain one or the more abrasive grains；
(3) caoutchouc elasticity matrix is dissolved using organic solvent, resin prepared in step (2) is then added
Grain simultaneously pours into mold after mixing evenly, and being put into baking oven drying makes it be formed by curing abrading block；
(4) abrading block after solidification trimmed, shaping, be fabricated to the rubber grinding tool for being used to grind and polish after bonding.
In a preferred embodiment, the caoutchouc elasticity matrix is specially natural rubber or nitrile rubber or butylbenzene rubber
Glue needs to select different types of caoutchouc elasticity matrix and deploy the hardness of caoutchouc elasticity matrix according to the use of rubber grinding tool.
In a preferred embodiment, the resin material is specially phenolic resin or epoxy resin, and is added specific auxiliary
Expect the bond strength between reinforced resin and abrasive grain.
In a preferred embodiment, the abrasive grain is specially diamond or corundum or boron nitride；The partial size of the abrasive grain
It is selected according to the surface quality requirements of processing object.
In a preferred embodiment, the organic solvent is specially toluene or dimethylbenzene or gasoline.
In a preferred embodiment, the concentration of the abrasive grain is the 10%-30% of caoutchouc elasticity matrix.
In a preferred embodiment, the shape of the rubber grinding tool is designed to concrete shape and ruler according to requirements
It is very little, it is used for various forms of grindings and polishing.
In a preferred embodiment, using rolling refining glue mode by the resin particle prepared and caoutchouc elasticity matrix into
Row is uniformly mixed, and is then fabricated to all kinds of rubber grinding tools by being heating and curing.
Compared to the prior art, technical solution of the present invention have it is following the utility model has the advantages that
The present invention proposes a kind of preparation method of rubber grinding tool, by coating one layer of resin, a side in rubber abrasive particle surface
Face overcomes the shortcomings that abrasive grain poor bonding strength in traditional grinding tool, on the other hand remains the excellent of traditional rubber grinding tool high flexibility again
Point；The surface area of abrasive grain and rubber contact is increased, the binding force that rubber rolls into a ball abrasive grain can be effectively improved, while grinding tool still has
There is biggish elasticity, preferable machined surface quality can be obtained.Rubber grinding tool provided by the invention, which not only has, preferably to be cut
Performance is cut, also can get preferable surface quality, is very suitable to the precise finiss and polishing of fragile material.
