Abstract

Provided are an elastic abrasive disc and a manufacturing process thereof. The elastic abrasive disc comprises a label layer, a supporting layer and a polishing layer, wherein the supporting layer islocated between the label layer and the polishing layer, the label layer, the supporting layer and the polishing layer are in the same shapes and are in circular ring shapes, mounting holes are formedin the centers of the label layer, the supporting layer and the polishing layer, and the label layer, the supporting layer and the polishing layer are solidified to be of an integrated structure by being heated in a die. The elastic abrasive disc and the manufacturing process have the beneficial effects that the manufacturing process is simple, the weight is low, the elastic abrasive disc cannotswing when being mounted on a tool, the safety performance is high, the elastic abrasive disc is degradable, high in grinding efficiency and high in self-sharpening performance, the use rate of abrasive cloth is high, the elastic abrasive disc is suitable for polishing of corners and gaps, the size is small, the package and transportation cost is low, the shape is smooth, wind resistance is small,and there is almost no noise at work.

Description

technical field

[0001] The invention belongs to the field of abrasive abrasives, and in particular relates to an elastic sand disc and a production process thereof. Background technique

[0002] The elastic grinding disc is also called the louver wheel, also known as the flat emery cloth wheel and the louver. It is a commonly used abrasive tool. Although it has a certain grinding effect, it also has very large disadvantages. For example: the elastic grinding disc is relatively heavy, and the installation It is easy to swing when it is on the tool, and it needs to be manually fixed and stabilized during operation. The production process is cumbersome, the safety performance is low, it cannot be degraded, the self-sharpening performance is not strong, the usage rate of the abrasive cloth is not high, it is not suitable for grinding corners and crevices, and it is large. The quality is heavy, the cost of packaging and transportation is high, and the noise during work is relativ...

Examples

Embodiment

[0043] as attached figure 1 To attach image 3 Shown:

[0044] An elastic sand disc, which includes a label layer 1, a support layer 2 and a grinding layer 3, the support layer 2 is located between the label layer 1 and the grinding layer 3, and the three have the same shape, all in the shape of a ring, There is an installation hole 4 in the center, and the label layer, the support layer and the polishing layer are heated and solidified in the mold after pouring glue to form an integrated structure; the support layer 2 is plant jute, which is processed by dipping, drying, and cutting. Replacing traditional materials with degradable plant fibers has low cost and high specific strength. At the same time, it has a certain toughness, and the vibration is small during the grinding construction, so it will not hurt the workpiece.

[0045] Label layer 1 is label paper.

[0046] Grinding layer 3 is emery cloth.

[0047] The label layer, the support layer and the grinding layer ar...
