High-strength anti-static coated abrasive tool cloth base and treatment process thereof

Abstract

The invention provides a treatment process of a high-strength anti-static coated abrasive tool cloth base. The treatment process comprises the following steps of S1, conducting desizing treatment; S2, respectively preparing an anti-static impregnated sizing material, an anti-static non-sand-planting surface blade coating sizing material and an anti-static sand-planting surface blade coating sizing material; S3, impregnating by adopting the impregnated sizing material; S4, conducting blade coating on the non-sand-planting surface of the cloth base by adopting the non-sand-planting surface blade coating sizing material; S5, conducting blade coating on the sand planting surface of the cloth base by adopting the sand planting surface blade coating sizing material; and S6, conducting ironing setting treatment and quick-cooling setting treatment on the cloth base treated in the above-mentioned steps. The invention further provides a coated abrasive tool cloth base. Through impregnation, non-sand-planting surface blade coating and sand-planting surface blade coating, the treated cloth base forms a conductive channel from the non-sand-planting surface to the sand-planting surface, so that the anti-static property of the cloth base is improved; the mechanical strength of the cloth base is improved through the sizing material in the cloth base; and through ironing setting treatment and quick-cooling setting treatment, internal molecules of the cloth base are directionally arranged in the setting process, and the strength of the cloth base is improved.

Description

technical field [0001] The invention relates to the technical field of abrasive tools, in particular to a high-strength antistatic coated abrasive cloth base and a treatment process thereof. Background technique [0002] The traditional antistatic coated abrasive cloth generally adopts two methods for antistatic treatment, such as: adding antistatic agent to the rubber compound, conductive material or metal wire inside the base material for product antistatic treatment. However, the metal wire is easy to discharge in the electrostatic field, resulting in uneven sand planting or inclined abrasive grains, which affects the quality of electrostatic sand planting. Adding antistatic agents and conductive materials to the rubber compound often fails to achieve the desired effect because there is no path formed inside the cloth base. In addition, traditional cloth base reinforcement generally uses thicker yarn count or density to increase the strength of the cloth base. However, t...

AI Technical Summary

Problems solved by technology

However, the metal wire is easy to discharge in the electrostatic field, resulting in uneven sand planting or inclined abrasive grains, which affects the quality of electrostatic sand planting

Antistatic agents and conductive materials are added to the rubber compound, because there is no path formed inside the cloth base, the expected effect is often not achieved

In addition, the traditional reinforcement of the cloth base generally uses thicker yarn count or density to increase the strength of the cloth base. However, the yarn count and density of the cloth base have certain limits, and cannot continue to increase after reaching a certain value.
