Abstract

The utility model relates to a coated abrasive tool, in particular to three-dimensional elastic polishing emery cloth which comprises a base body and abrasive particles. The base body is a three-dimensional, bouffant and sparse non-woven sheet-shaped object which is formed by combining short fiber which is mutually wound and randomly arranged, and meanwhile resin particles with the abrasive particles are adhered to the surface of inner fiber of the sheet-shaped object. The three-dimensional elastic polishing emery cloth is of a three-dimensional structure, has certain elasticity and flexibility, does not easily scratch workpieces, has good heat dissipation performance, and is long in service life.

Description

Three dimensional elasticity polishing emery cloth

Technical field

The utility model relates to a kind of coated abrasive tool, particularly a kind of three dimensional elasticity polishing emery cloth.

Background technology

The scope of application of coated abrasive tool is more and more extensive, and traditional coated abrasive tool is basic as the back of the body take cloth or paper, sand is coated with equably be bonded on back of the body base, forms the planar structure of two dimension, and this product of this structures shape has certain rigidity and inside comprises less space.In use, easily produce scuffing at surface of the work, and abrasive dust is easy to stop up grinding face, causes reduce its service life, surface of the work is easily burnt.

Summary of the invention

In order to overcome deficiency of the prior art, we design a kind of three dimensional elasticity polishing emery cloth.

According to design provided by the utility model, a kind of three dimensional elasticity polishing emery cloth, contain matrix and abrasive grains, it is characterized in that: described matrix is the bulk sparse three-dimensional non-woven tablet that a kind of synthetic staple of mutual winding random alignment forms, and while fiber surface in described tablet adheres to the resin plastochondria with abrasive grains.

Described synthetic staple material polymers can be for polyamide, polyester are poly-, polypropylene, PEF.

Described abrasive grains can be alumina abrasive particle, silicon carbide abrasive particle, garnet abrasive particle, quartzy abrasive grain, diamond abrasive grains.

Described resin plastochondria material can be thermosetting resin, thermoplastic resin, or is more than one resin compound.

The beneficial effects of the utility model:

1, the utility model three dimensional elasticity polishing emery cloth consists of the coated abrasive tool with three-dimensional space with synthetic staple, abrasive grains, resin plastochondria, have certain elasticity and flexibility, be difficult for causing surface of the work to scratch, do not change the size, the shape that are polished object.

2, the utility model three dimensional elasticity polishing emery cloth inside has large quantity space to make three dimensional elasticity polishing emery cloth surface be difficult for being stopped up by abrasive dust and having good thermal diffusivity, thereby this coated abrasive tool has longer service life, and is difficult for the burn surface of the work in use procedure.

Description of drawings:

Fig. 1 is the utility model three dimensional elasticity polishing emery cloth schematic diagram;

Fig. 2 is the utility model three dimensional elasticity polishing emery cloth three-dimensional structure schematic diagram.

The specific embodiment:

Number in the figure 1 represents synthetic staple, and label 2 represents abrasive grains, and label 3 represents the resin plastochondria.

Referring to Fig. 1 ~ 2, a kind of three dimensional elasticity polishing emery cloth, three dimensional elasticity polishing emery cloth, contain matrix and abrasive grains 2, matrix is the bulk sparse three-dimensional non-woven tablet that a kind of synthetic staple 1 of mutual winding random alignment forms, and fiber 1 surface attachment is with the resin plastochondria 3 of abrasive grains 2 in described tablet simultaneously, and in the present embodiment, synthetic staple 1 material polymers is polyamide, abrasive grains 2 is quartzy abrasive grain, and resin plastochondria 3 materials are thermosetting resin.

Can form a plurality of embodiment by change synthetic staple 1 polymer, abrasive grains 2 materials, resin plastochondria 3 materials, all belong to the protection domain of this patent.
