Embodiment 1

[0033] A kind of emery cloth, such as figure 2 As shown, a flexible base layer 1 and a number of grinding particles 2 are included. The flexible base layer 1 has a front surface. The grinding particles 2 are independently and directly fixed to the front surface of the flexible base layer 1, and the grinding particles have the same structure. The flexible base layer 1 can be cloth or paper.

[0034] The grinding particles 2 are a mixture of abrasive particles and resin. The size of the abrasive particles is between 0.5 and 1000 microns, preferably between 1 and 100 microns. The smaller the range between the size of the abrasive particles, the better the surface finish of the ground product. This embodiment In the abrasive grains, diamond is used, but the present invention is not limited to diamond. The rest are fused alumina, heat-treated alumina, silicon carbide, alumina-zirconia, garnet, cubic boron nitride, or a mixture of the above , Can also be applied to the present invention...

Embodiment 2

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

[0040] A manufacturing method of emery cloth, the manufacturing method includes:

[0041] (1). The first step: all cavities of the mold are filled with a liquid mixture slurry of grinding particles 2, which is also a slurry of a mixture of abrasive particles and resin, where the mass ratio of abrasive particles to resin is 1 :1, preferably the mass ratio is (3 to 2) parts: 1 part, the m...

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 an abrasive product and a manufacturing method thereof, in particular to an emery cloth and a manufacturing method thereof. Background technique [0002] At present, well-known grinding products, such as figure 1 As shown, it includes a base layer 1'and a grinding layer 2'fixed on the front surface of the base layer 1'. The grinding layer 2'includes an integrally formed working layer 21' and a plurality of protruding from the front surface of the working layer 21' The grinding particles 22', wherein the grinding layer 2'is a mixture of abrasive particles and resin. The grinding product has the following shortcomings: First, the grinding layer 2'is a hard layer, which is rigid and not soft, and cannot be polished at the curved surface or water chestnut of the product, and it cannot conform to the polished product; second, The grinding layer 2'includes a working layer 21' and grinding particles 22', wasting abrasive particles and res...
