不同粒径铜尾矿对天然橡胶硫化及机械性能的影响
Effect of Copper Tailings with Different Particle Sizes on Vulcanization and Mechanical Properties of Natural Rubber
摘要
Abstract
The article investigates the effects of copper tailings with different particle sizes on the vulcanization and mechanical properties of natural rubber.A universal tensile testing machine,DIN abrasion tester,compression heat generation tester,Fourier transform infrared spectroscopy and scanning electron microscopy are employed to test and characterize the copper tailings/natural rubber composites.The results show that an increase in the amount of copper tailings added delays rubber vulcanization and leads to an increase in tensile strength,elongation at break and 200％modulus.Compared to coarse tailings,fine tailings can achieve higher tensile strength and modulus.The dynamic compression temperature rise value of the rubber material increases with the addition of more copper tailings,and the dynamic compression temperature rise value of the rubber material prepared with fine tailings is lower than that prepared with coarse tailings.When 10～50 phr of copper tailings are added,the abrasion resistance improves with the increase of adding amount.When the adding amount of coarse copper tailings exceeds 50 phr,more voids appear in the rubber matrix,while no voids are observed in the rubber matrix when 30～70 phr of fine tailings are added.关键词
