AI Technical Summary
Technical Problem
Traditional synchronous belts are prone to slippage on the outer ring after a short cycle and are not wear-resistant, making it difficult to meet market demands.
Method used
A composite synchronous belt with high wear resistance and anti-slip properties is prepared by using polyurethane adhesive. By adding modified silica, polyhydroxysiloxane polymer and Schiff base to the outer ring of polyurethane adhesive, a UV absorber is formed to form chemical bonds, thereby improving the bonding strength and anti-slip properties.
Benefits of technology
It significantly improves the synchronous belt's resistance to ultraviolet rays, corrosion, wet slip, and wear, and extends its service life.
