Problems solved by technology

[0004] However, the traditional diamond soft grinding discs use glue to bond diamond and filler together. Since diamond is a mineral composed of carbon elements, it has poor compatibility with the glue, and it has not been cross-linked and solidified by hot pressing, so the bonding force is weak. Poor, resulting in low flexural strength, poor wear resistance and short service life of the produced soft abrasive discs

Embodiment 1

[0038] Embodiment 1: A kind of diamond soft grinding disc, comprises flexible base material and the grinding and polishing working layer that is attached to one side of flexible base material, and flexible base material is Velcro cloth, and the raw material of grinding and polishing working layer and corresponding mass percentage thereof are as shown in the table 1, and prepared by the following steps:

[0039] Step 1, uniformly mixing diamond, ultrafine aluminum oxide, aluminum hydroxide, sepiolite wool, α-cellulose, powdered rubber, and varnish powder to obtain a mixture;

[0040] Step 2: Put the mixed material into the forming mold, hot press and sinter under the conditions of temperature 150°C, time 20min, and pressure 45T to obtain the grinding and polishing working layer;

[0041] Step 3, bonding the grinding and polishing working layer with the flexible substrate to obtain a soft diamond grinding disc.

Embodiment 2-5

[0042] Embodiment 2-5: A soft diamond grinding disc, the difference from Embodiment 1 is that the raw materials of the grinding and polishing working layer and their corresponding mass percentages are shown in Table 1.

Abstract

The invention discloses a diamond soft grinding disc and a preparation method thereof, and relates to the technical field of grinding materials. The diamond soft grinding disc is characterized by comprising a flexible substrate and a grinding and polishing working layer attached to one surface of the flexible substrate; and the grinding and polishing working layer comprises the following components in percentage by mass: 10-20% of diamond, 5-10% of superfine alumina, 2-8% of aluminum hydroxide, 1-5% of sepiolite velvet, 2-6% of alpha-cellulose, 0.5-2% of powder rubber, and the balance opacifying powder. The diamond soft grinding disc has the advantages of good wear resistance and high toughness.

Description

technical field [0001] The invention relates to the technical field of abrasive materials, more specifically, it relates to a soft diamond abrasive disc and a preparation method thereof. Background technique [0002] The diamond soft grinding disc is composed of a flexible base material and a grinding and polishing working layer attached to the base material. The grinding and polishing working layer is mainly made of diamond and resin materials, and the back of the base material is glued with a Velcro cloth. When working, it is glued on the joint of the mill for grinding and polishing. It is used for special-shaped processing of stone, ceramics, floor tiles and other materials. It is suitable for stone polishing, line chamfering, curved plate and special-shaped stone processing, and can also be used for Special-shaped processing, repair and renovation of marble, concrete, cement floor, terrazzo, glass-ceramic, artificial stone, floor tiles, glazed tiles, vitrified tiles. ...
