Problems solved by technology

Especially in terms of wear resistance and water resistance, the performance is poor
There is a lack of suitable high-speed grinding products, especially in terms of water resistance. The water-resistant products used in China are still at the level of the 1960s. The specific performance is: (1) Water resistance. Low cutting efficiency
(2) The alkyd resin used has low bonding strength, the abrasive is easy to fall off during use, and the wear resistance is poor
(3) The adhesive used is brittle, and the emery cloth is easy to age, and cracks will appear after being placed for about two months, which will seriously affect the performance

Embodiment Construction

[0005] This specific embodiment adopts the following technical scheme: firstly, select the carrier purified fiber cloth and then perform special treatment, fluff the surface of the gray cloth, cut off the wool on the surface of the gray cloth evenly, make the surface of the gray cloth clean, and then wash and dry it with water. High temperature setting at 250°C, so that the shape of the gray cloth can be reprocessed under a stable premise. For the flatness of the base cloth and the primer is not easy to penetrate when making sand planting, and it can also be well bonded with the primer, and then Carry out two pulping, then front coating, back coating formula; finally manufacture production, choose zirconia corundum abrasive and high temperature calcined brown corundum abrasive, because zirconia corundum mainly contains zirconia, zirconia is very hard and easy to break, so we Zirconium corundum and brown corundum were used in the ratio of 7:3 for electrostatic sand planting and ...

Abstract

The invention provides zirconia-corundum super coating abrasive cloth, and relates to abrasive cloth for grinding, in particular to corundum super coating abrasive cloth. The zirconia-corundum super coating abrasive cloth adopts the following technical proposal: firstly selecting carrier pure chemical fiber raw cloth for special treatment, fluffing the surface of the raw cloth, clipping off fluff evenly on the surface of the raw cloth, rinsing and drying the raw cloth, carrying out forming by high temperature at 210 to 250 DEG C, and then carrying out twice rolling, front coating and back coating for recipe; and finally manufacturing the abrasive cloth, adopting a zirconia-corundum abrasive material and a high temperature calcination brown corundum abrasive material, carrying out zirconia-corundum electrostatic sand planting and gravity sand planting according to the proportion of zirconia-corundum to brown corundum 7:3; and adopting first and second rubber covering. The abrasive cloth is mainly used for the polishing and the grinding in the metal field such as stainless steel, which is impractical for other abrasive cloth.

Description

Technical field: [0001] The invention relates to an emery cloth for grinding, in particular to a corundum super-coated emery cloth. Background technique: [0002] At present, the consumption of high-grade grinding materials in China is wide and large, with an annual consumption of about 200 million square meters, and the grade of domestic coated abrasive products is relatively low. Especially in terms of wear resistance and water resistance, the performance is poor. There is a lack of suitable high-speed grinding products, especially in terms of water resistance. The water-resistant products used in China are still at the level of the 1960s. The specific performance is: (1) Water resistance. Cutting efficiency is low. (2) The alkyd resin used has low bonding strength, and the abrasives are easy to fall off during use, and the wear resistance is poor. (3) The adhesive used is brittle, and the emery cloth is easy to age, and cracks will appear after being placed for about t...
