Abstract

The utility model relates to an anti-blocking sand paper, which belongs to layered flexible abrasive. The utility model comprises a basal body (1), wherein the abrasive (3) is attached to the basal body (1). The utility model is characterized in that the abrasive (3) is composed of a plurality of unit bodies (5), and gaps (4) are arranged between each unit body (5). the anti-blocking sand paper of the utility model breaks through the whole covered technique on the basal body of the existing sand paper abrasive, realizes the incomplete coverage of the abrasive, enables the abrasive to have a certain geometric shape on the surface of the sand paper, has the favorable action of preventing block, avoids the problem of the falling of grinding performance through thin planting sand to prevent clogging and has very obvious superiority.

Description

Anti-blocking sand paper

Technical field

The utility model relates to a kind of stratiform flexible abrasive material, is specifically related to a kind of sand paper.

Background technology

Coated abrasive tool is made up of matrix, adhesive, abrasive material three parts, and general production technology is at first to be coated with primer on matrix, then by planting sand, predrying after, coated glue again twines behind the dry solidification and rolls out, and carries out post processing again and makes product.General coated abrasive tool exists the situation of obstruction that the performance of coated abrasive tool is descended rapidly when in use even can not use, and has had a strong impact on the service life and the grinding surface quality of product.In order to address this problem, normally be coated with the super coating of one deck again on the surface of sand paper, also have by reduction and plant the sand amount---thin planting sand increases so that the dust such as wood chip that produce are in time discharged the gap between the sandpaper abrasive when grinding, thereby prevents to stop up.But the method by thin planting sand prevents obstruction and can cause the grinding performance of sand paper to descend, and be coated with super coating and also just prevents obstruction to a certain extent, just plays a role at the use initial stage, carrying out coating and can come off very soon along with grinding.

The utility model content

Technical problem to be solved in the utility model is in order to overcome above-mentioned defective, a kind of anti-blocking sand paper that makes sand paper can better prevent under the prerequisite that does not reduce grinding performance and stop up to be provided.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: anti-blocking sand paper, comprise matrix, and adhere to abrasive material on the matrix, its abrasive material is made up of a plurality of cell cubes, between each cell cube the space is arranged.

Described anti-blocking sand paper, its cell cube are polygon.

Described anti-blocking sand paper, its cell cube are circular.

Described anti-blocking sand paper, its cell cube are oval.

Described anti-blocking sand paper, its cell cube are irregularly shaped.

Described anti-blocking sand paper, its cell cube are triangle.

Described anti-blocking sand paper, its cell cube are quadrangle.

Described anti-blocking sand paper, its cell cube are pentagon.

Described anti-blocking sand paper, its cell cube are hexagon.

Described anti-blocking sand paper, its cell cube are octagon.

Compared with prior art the beneficial effect that the utility model had is: anti-blocking sand paper of the present utility model sand paper different from the past plant sand fully, there is a fixed gap on the surface of sand paper, abrasive material exists with certain shape on the surface of sand paper, such design can make the dust such as wood chip that produce in grinding discharge rapidly by the space that does not have abrasive material, effectively prevented stopping state, owing to be not thin planting sand, guaranteed the good grinding performance of sand paper simultaneously; The design point of this novel sand paper has been to break through sandpaper abrasive whole technology that cover on matrix in the past, realized the incomplete covering of abrasive material, can make abrasive material have certain geometry in coated abrasive surface, for preventing to stop up good effect is arranged, avoided problem when preventing to stop up simultaneously, the problem includes: the problem that grinding performance descends has very obvious superiority by thin planting sand.

The specific embodiment

1 matrix, 2 primers, 3 abrasive materials, 4 spaces, 5 cell cubes

As shown in Figure 1, be coated with primer 2 on the matrix 1, put abrasive material 3 on the primer 2, abrasive material 3 is made up of a plurality of cell cubes 5, between each cell cube 54 spaces is arranged.Dust such as the wood chip that produces in the grinding are discharged rapidly by the space 4 that does not have abrasive material, have effectively prevented stopping state, owing to be not thin planting sand, have guaranteed the good grinding performance of sand paper simultaneously.
