Description

Technical Field

[0001] This utility model belongs to the field of abrasive belt technology, and more specifically, relates to an abrasion-resistant abrasive belt base cloth and abrasive belt. Background Technology

[0002] Abrasive belts, as an important grinding tool, are widely used in the grinding of metals, wood, ceramics, and other materials. Abrasive belts generally consist of three parts: a base cloth, an adhesive, and abrasive particles. The abrasive particles are bonded to the base cloth via the adhesive to form a flexible grinding system. The wear resistance of the base cloth significantly affects the overall grinding performance, mechanical properties, service life, and grinding stability of the abrasive belt. Therefore, the technical requirements for the base cloth are good wear resistance and good grinding stability to ensure a long service life. Currently, abrasive belt base cloths are mostly made of materials such as cotton and polyester. The strength and elongation of cotton-based abrasive belt base cloth fluctuate significantly with humidity. Synthetic fiber-based abrasive belt base cloths, such as polyester, have poor heat resistance, poor heat dissipation, and low wear resistance. While pure polytetrafluoroethylene (PTFE) abrasive belt base cloths have a low surface friction coefficient, the material itself exhibits a "cold flow" phenomenon, resulting in poor wear resistance. Therefore, existing abrasive belt base cloths suffer from poor wear resistance and heat generation, leading to a shorter service life for the abrasive belt. Utility Model Content
