The above problems have been solved in the prior art; for example, patent number CN211441400U proposes a nylon abrasive belt for grinding glass substrates, which comprises a nylon three-dimensional substrate and an elastic substrate, wherein the whole surface of any fiber yarn of the nylon three-dimensional substrate is covered with a bonding layer, the surface of the bonding layer is subjected to electrostatic sand planting or gravity sand planting to form an abrasive particle layer, and the nylon three-dimensional substrate and the elastic substrate are bonded into a whole. According to the utility model, the nylon abrasive belt is formed by combining the nylon three-dimensional base layer and the elastic base layer, so that the nylon abrasive belt has better elasticity during polishing, can play a role in heat dissipation, and is not easy to generate edge breakage and overgrinding during polishing. The polyester cloth is adopted as the base band, so that the nylon abrasive band has better fatigue resistance, the service life of the nylon abrasive band can be prolonged, the frequency of replacing the abrasive band is reduced, the production efficiency is indirectly improved, and the glass edge angle polishing performance is better. The abrasive particles are uniformly adhered to the fiber wires, are uniformly distributed, and adopt silicon carbide abrasive particles to meet the use requirement of glass grinding and polishing, and the polishing surface is flat and smooth.

However, after the surface abrasive grains of the nylon abrasive belt used at present are worn out, the worn-out effect is poor, and the nylon abrasive belt needs to be replaced, so that the service life of the conventional abrasive belt is not long, the abrasive belt is not wear-resistant, and frequent replacement is needed in the use process and the time is wasted.
