Embodiment 1

[0033] A kind of emery cloth, as shown in Figure 2, comprises a piece of flexible base 1 and several grinding grains 2, and flexible base 1 has a front, and grinding grain 2 is all independently directly fixed on the front of flexible base 1, and each grain The abrasive particles have the same structure. The flexible base layer 1 can be cloth or paper.

[0034] Abrasive grains 2 are a mixture of abrasive grains and resin. The size of the abrasive grains is between 0.5 and 1000 microns, preferably between 1 and 100 microns, wherein the smaller the size of the abrasive grains, the better the surface finish of the ground product. In this embodiment Among them, diamonds are used as abrasive grains, but the present invention is not limited to diamonds, and others such as fused alumina, heat-treated alumina, silicon carbide, alumina-zirconia, garnet, cubic boron nitride, or a mixture of the above , is also applicable to the present invention. Resin is preferably the resin that ca...

Embodiment 2

[0039] This embodiment introduces a manufacturing method that can manufacture the above-mentioned emery cloth. Another matching mold has a parting surface on the mold, and a plurality of independent cavities are opened on the parting surface. The number and arrangement of the cavities are respectively the same as the number and arrangement of the grinding particles 2 of the gauze. The same, and the shape of the concave cavity is the same as the shape of the grinding particle 2, which is also a hemispherical shape, and its diameter is between 1 and 5 mm. Wherein, the mold material can be flexible plastic or rubber, such as polypropylene.

[0040] A method for manufacturing emery cloth, the method comprising:

[0041] (1). The first step: All the cavities of the mold are filled with a mixture slurry of liquid grinding particles 2, which is also a slurry of a mixture of abrasive particles and resin, wherein the mass ratio of abrasive particles to resin is 1 : 1, preferably a ma...

Abstract

An abrasive cloth is composed of a flexible substrate (cloth), and multiple abrasive particles fixed to the front surface of said flexible substrate. Its preparing process includes such steps as filling the mixture of liquid and abrasive particles in the pits on the parting surface of mould, removing residual mixture, spreading a flexible substrate on the parting surface, pressing while solidifying said mixture, and taking the finished abrasive cloth.

Description

Technical field [0001] The invention relates to a grinding product and a manufacturing method thereof, in particular to an emery cloth and a manufacturing method thereof. Background technique [0002] At present, known grinding products, as shown in Figure 1, include a base layer 1' and a grinding layer 2' fixed on the front of the base layer 1', and the grinding layer 2' includes an integrally formed working layer 21' And several grinding particles 22' protruding from the front of the working layer 21', wherein the grinding layer 2' is a mixture of abrasive particles and resin. This grinding product has the following disadvantages: first, the grinding layer 2' is a hard layer, which is stiff and not soft, and cannot be polished on the curved surface or water chestnut of the product, and cannot be well adhered to the polished product; second, The grinding layer 2' includes the working layer 21' and the grinding particles 22', which wastes the abrasive particles and resin, a...
