Description
Technical field
The utility model relates to the utensil of architectural engineering, particularly relates to a kind of abrasive disc.
Background technology
At present, in state's inner concrete grinding industry, widely used abrasive disc is resin-based abrasive disc.Usual this abrasive disc is circular, comprises the abradant surface for contacting with concrete and the joint face for grinder be connected opposing with abradant surface.Although the reasons such as this abrasive disc can complete concrete grinding, low because of the intensity of resin own, to wear no resistance cause the defects such as this abrasive disc sharpness is low, grinding efficiency is poor, service life is shorter.
Utility model content
The purpose of this utility model is to provide the abrasive disc that a kind of grinding efficiency is higher, service life is longer.
Abrasive disc of the present utility model, comprises matrix, and described matrix comprises abradant surface for contacting with concrete and the joint face for grinder be connected opposing with abradant surface, and described abradant surface is provided with wear body.
Abrasive disc of the present utility model, wherein, described abradant surface is provided with multiple groove, and described abradant surface is divided into multiple abrasive areas by multiple described groove, is at least provided with a described wear body in each abrasive areas.
Abrasive disc of the present utility model, wherein, described wear body is combined with described matrix by inlaying.
Abrasive disc of the present utility model, wherein, described wear body is metal dust wear body or diamond wear proof body, and described wear body is quadrangle on described abradant surface.
Abrasive disc of the present utility model, wherein, described abradant surface is circular, described groove comprise extended to the circumference of described abradant surface by the center of circle of described abradant surface respectively four straight flute, around the quadrangle groove in the center of circle of described abradant surface and four valley gutters being extended by the circumference of abradant surface described in four angles of described quadrangle groove respectively, described abradant surface is divided into 12 abrasive areas by described four straight flute, quadrangle groove, four valley gutters, is provided with a described wear body in each abrasive areas.
Abrasive disc of the present utility model, matrix on the abradant surface contacted with concrete, be provided with wear body.The main material of matrix is resin, and the material of wear body is metal dust and diamond.Abrasive disc of the present utility model compares that existing abrasive disc grinding efficiency is higher, longer service life.
Accompanying drawing explanation
Fig. 1 is the top view of the structural representation of abrasive disc of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Detailed description of the invention
As shown in Figure 1 and Figure 2, abrasive disc of the present utility model comprises matrix 1, and matrix 1 comprises abradant surface 11 for contacting with concrete and the joint face 12 for grinder be connected opposing with abradant surface 11, abradant surface 11 is provided with wear body 2.
Abrasive disc of the present utility model, wherein, abradant surface 11 is provided with multiple groove, and abradant surface 11 is divided into multiple abrasive areas 4 by multiple groove, is at least provided with a wear body 2 in each abrasive areas 4.
Abrasive disc of the present utility model, wherein, wear body 2 is combined with matrix 1 by inlaying.
Abrasive disc of the present utility model, wherein, wear body 2 is metal dust wear body or diamond wear proof body, and wear body 2 is quadrangle on abradant surface 11.
Abrasive disc of the present utility model, wherein, abradant surface 11 is circular, groove comprise extended to the circumference of abradant surface 11 by the center of circle of abradant surface 11 respectively four straight flute 31, around the quadrangle groove 32 in the center of circle of abradant surface 11 and four valley gutters 33 being extended by the circumference of four angle abradant surfaces 11 of quadrangle groove 32 respectively, abradant surface 11 is divided into 12 abrasive areas 4 by four straight flute 31, quadrangle groove 32, four valley gutters 33, is provided with a wear body 2 in each abrasive areas.
Abrasive disc of the present utility model, matrix on the abradant surface contacted with concrete, be provided with wear body.The main material of matrix is resin, and the material of wear body is metal dust and diamond.Abrasive disc of the present utility model compares that existing abrasive disc grinding efficiency is higher, longer service life.
The abrasive disc of prior art is because material is mainly resin, and often there will be the phenomenon of abrasive disc fracture in the low bruting process of intensity, abrasion resistance is poor, often pays abrasive disc resin abrasive disc and can only to polish hundreds of square meter.
Abrasive disc of the present utility model is more than five times of the abrasive disc of prior art service life, greatly reduces construction cost thus.
Abrasive disc of the present utility model can be prepared by following steps:
1, batch mixing
The mixing of 1.1 resin powders
The mixing of 1.2 metal powder materials
2, sulfuration sintering
2.1 sintering
Mixed metal powder material is sintered according to technical requirement under certain temperature, pressure, time, becomes wear body.
2.2 sulfuration
The wear body sintered is implanted in mould, the resin powder mixed is inserted vulcanization forming in mould.
3, mould unloading
After certain hour, from vulcanizer, mould is taken off, be put on Miniature oil press and carry out the demoulding, take out product.
4, bonding die
Product applies glue after taking out overleaf, also applies glue, both be bonded together on corresponding nylon cloth.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
