Abstract

The utility model discloses a sand table with an organic fibre matrix, which comprises a matrix pressed by plasticizing a chemical fibre fabric, wherein the center of the matrix is provided with an iron ring, and an abrasive layer is adhered to the matrix. The matrix disclosed by the embodiment is made of pure chemical fibre as follows: the matrix is manufactured by plasticizing fabrics, such as nylon, polyester, acrylonitrile; and the surface of the matrix is coated with an adhesive and is adhered with an abrasive so as to form a novel sand table, and sand tables manufactured by matrices manufactured by materials, such as purified-cotton vulcanized fiber paper, glass fibre, engineering plastics, in the traditional market are replaced. The sand table with the organic fibre matrix has excellent performance of water resistance, no deformation, large elasticity, good anti-fatigue bending strength exceeding the fatigue bending strength of the materials and the like. Compared with sand tables with matrices manufactured by other materials, the service life can be enhanced by more than 20 percent.

Description

A kind of organic fiber matrix emery disc

Technical field

The new shape of this practicality belongs to the grinding tool technical field, is specifically related to a kind of emery disc.

Background technology

Emery disc (claiming the high speed abrasive disc again) is a kind of various surface finish, instrument of grinding of being used in the grinding tool class.Its preparation method mainly is abrasive material is sticked on the emery disc matrix with binding agent and to process.The emery disc matrix is a key factor of making emery disc.It relates to operator's security in use.

This kind of enterprise production product mainly adopts textile fiberboard to make the emery disc matrix both at home and abroad at present.But this matrix is easy to moisture absorption and deformation, and it is short to store decay period, and fatigue resistance is low, and becomes the defective that can't overcome.Someone begins to form with other material and makes the emery disc matrix.For example use glass fibre, perhaps stick on the first-class method of glass fibre with cotton makes matrix to various engineering plastics, is stained with abrasive material, makes emery disc.But the product that said method is processed all can produce new defective.Like the emery disc that fiberglass-based system becomes, in grinding, glass fibre and abrasive material are dispersed in the air simultaneously, suck operator's lung, and stick on the skin, form serious occupational disease.The emery disc matrix made from engineering plastics (like nylon, polystyrene, SBS, polyester etc.).Make with in, elasticity is little.Counter-bending fatigability is poor, not even as the matrix processed of textile fiber safe.So domestic and international so far grinding tool manufacturing does not still have appearance and can solve existing defective good method on the above-mentioned emery disc manufacture craft comprehensively.

The utility model content

The purpose of the new shape of this practicality is to above-mentioned the problems of the prior art, and a kind of organic fiber matrix emery disc is provided, and the floating thing that produces in can moistureproof water-fast indeformable, counter-bending fatigue strength high, the grinding is not hindered skin, and good springiness.

The technical scheme of the new shape of this practicality realizes in the following manner: a kind of organic fiber matrix emery disc, comprise the matrix that the plasticizing of chemical fibre braid is suppressed, and the center of matrix is provided with iron ring, is stained with abrasive material on the matrix.

Said abrasive material is provided with groove.

Said matrix bottom surface is a circular arc.

Said matrix is a cymbals shape.

The present embodiment matrix is the pure chemistry fiber: process matrix like braids such as nylon, polyester, acrylonitrile through plasticizing; Coat binding agent at its table and be stained with abrasive material and become novel emery disc, substitute the emery disc that matrix that material such as existing textile vulcan fibre, glass fibre, engineering plastics on the market does is processed.Have premium properties such as tired Qu Qiangdu water-fast, indeformable, that elasticity big, the antifatigue bending strength surpasses above-mentioned different materials.Compare with the matrix emery disc that other material is processed, can improve for 20% above service life.

The specific embodiment

Embodiment 1: as depicted in figs. 1 and 2, said organic fiber matrix emery disc comprises the matrix 1 that the plasticizing of chemical fibre braid is suppressed, and matrix 2 bottom surfaces are circular arc, and the center of matrix 1 is provided with iron ring 2, is stained with abrasive material 3 on the matrix 2.

In addition, the shape of matrix 2 also can be adjusted as required in the present embodiment, such as cymbals shape.

In the new shape of this practicality pure organic chemistry fiber is made yarn fabric, form the emery disc matrix, coat binding agent in its surface, be stained with abrasive material then, become through dry solidification " chemical fibre matrix emery disc " through the plasticizing compacting.Because of the pure chemistry fibrous braid has netted hole through the emery disc matrix surface that the plasticizing compacting forms, help the infiltration of binding agent, form root system shape tack coat; Make matrix, binding agent, abrasive material; The Trinity more firmly links to each other, and easy fracture does not separate, and has improved service life.The emery disc that this matrix of processing through plasticizing with chemical fibre is processed has in the water of being immersed in and also can not be out of shape, and elasticity is big, and the antifatigue bending strength all is higher than the emery disc that present existing on the market various material matrix are processed.And can keep the geometric shape of former national Specification, also can be as its material matrix emery disc.

Embodiment 2: like Fig. 3 and shown in Figure 4, said organic fiber matrix emery disc comprises the matrix 1 that the plasticizing of chemical fibre braid is suppressed; Matrix 2 bottom surfaces are cymbals shape; The center of matrix 1 is provided with iron ring 2, is stained with abrasive material 3 on the matrix 2, and said abrasive material 3 is provided with groove 4.

Present embodiment is provided with groove on abrasive material 3, can be used for intermittent grinding.

In addition, the shape of matrix 2 also can be adjusted as required in the present embodiment, is circular-arc such as the bottom surface.
