NOVELTY - High-strength abrasion-resistant type belt comprises 14.40-15.80% hollow glass beads, 19.80-20.60% PTFE, 3.60-4.80% reinforcing agent, and remaining nylon 66. USE - As high-strength abrasion-resistant type belt. ADVANTAGE - The belt has high-strength, and has effectively improved low-temperature resistance, aging resistance and abrasion resistance so that the belt can maintain excellent structural strength and abrasion resistance after UV aging treatment in a low temperature environment. The belt utilizes modified spherical nano alumina which can be loaded on the surface of graphene oxide and then blended into epoxy resin, and utilizes the modified nano titanium dioxide can be grafted with acrylonitrile, which can effectively enhance the anti-aging performance of the belt. In the method, simultaneously nano titanium dioxide is blended and doped into nylon 66, which can effectively improve the toughness, low temperature resistance and impact performance of the belt. The electrospinning is made into a reinforcing agent for nano-fiber structure which can effectively strengthen the low temperature resistance and abrasion resistance of the belt.
