Abstract

A novel type sanding film includes a sand layer and a matrix. The sand layer is enchased on the matrix, which is made from synthetic resin plate. Because the sand layer is attached on the matrix by the manner of enchasing, the grinding effect is better and the service life is longer.

Description

A kind of novel sand milling sheet

[technical field]

The utility model relates to a kind of grinding tool, relates in particular to a kind of with the abrasive segments of synthetic resin as matrix.

[background technology]

Existing abrasive disc is the most common with the vulcan fibre abrasive disc, and its utilization is also extensive.The vulcan fibre abrasive disc of commonly seeing is with binding agent abrasive materials such as corundum or carborundum to be sticked to as the surface of the vulcan fibre of matrix and a kind of coated mould of making, it can be installed in electric straight grinder, on electric angle grinder or the special-purpose sander, be applied to shipbuilding, automobile, the polishing of industries such as furniture, flash removed, beat weld seam, operations such as rust cleaning.

But the vulcan fibre abrasive disc uses in reality and has some shortcoming: form because its matrix vulcan fibre is merged by the multilayer cotton fiber, make the vulcan fibre abrasive disc easy deformation of making moist, not resistance to chemical attack and not wear-resisting, thereby the mill pin effect and the service life of reducing the vulcan fibre abrasive disc, and its production cycle is long.

[summary of the invention]

At the problem of above-mentioned existence, the purpose of this utility model provides a kind of water-fast, and acid and alkali-resistance is not easy distortion, the high and a kind of novel abrasive segments with short production cycle of intensity.

For realizing above-mentioned purpose, the technical solution of the utility model is to provide a kind of novel sand milling sheet to comprise: a matrix, and a layer of sand, wherein, this matrix is made by synthetic resin board, and described sand bed is embedded on the matrix that resin plate makes.

Advantage of the present utility model is: because matrix of the present utility model is not yielding to have, the synthetic resin board of resistance to chemical attack and wear-resisting characteristics is made, make abrasive disc not yielding, resistance to chemical attack and intensity height, simultaneously, be embedded on this substrate by sand bed, thereby the ground effect of raising abrasive disc makes its longer service life.

[description of drawings]

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the decomposition texture schematic diagram of a kind of novel sand milling sheet of the utility model.

Fig. 2 is the profile of a kind of novel sand milling sheet of the utility model.

[specific embodiment]

Below in conjunction with accompanying drawing the utility model is further detailed structure of the present utility model, characteristics and purpose.

As Fig. 1, shown in Figure 2, a kind of novel sand milling sheet 10 of the utility model comprises: a layer of sand 12 and a matrix 14, wherein, layer of sand 12 is embedded on the matrix 14, this matrix 14 uses synthetic resin board to make, and includes epoxy resin fiberglass cloth plate and phenolic resins cardboard, and such synthetic resin board is to use epoxy resin, synthetic resin such as phenolic resins infiltrate in as glass fabric, base materials such as wood-fibred are made through the HTHP sclerosis again, and it has wear-resisting, the characteristics of protection against the tide and resistance to chemical attack.Especially layer of sand 12 is attached on the aforesaid substrate 14 by the mode of inlaying, and its ground effect is better, longer service life.

Advantage of the present utility model is: because layer of sand 12 is attached on the aforesaid substrate 14 by the mode of inlaying, its ground effect is better, longer service life.

The above person is the utility model most preferred embodiment only, is not to be used to limit scope of the present utility model, and all equivalences of being done according to the utility model claim change or modify, and are all the utility model and contain.

Claims

1. a novel sand milling sheet comprises: a layer of sand (12) and a matrix (14) is characterized in that: described layer of sand (12) is embedded on the matrix (14), and this matrix (14) uses synthetic resin board to make.
