摘要
全世界每年产生大量废旧橡胶 ,它们需要很长时间才能降解 ,这既污染环境 ,又浪费资源 .废旧橡胶的处理 ,已成为橡胶工业面临的重要课题 .另一方面 ,随着振动及噪声的危害逐渐被人们认识 ,要求减振降噪的呼声日益高涨 .作为噪声及振动控制的主要方法之一 ,粘弹性阻尼减振技术得到迅速发展 ,对价低、质优的阻尼材料的需求快速增加 .本文将废胶粉进行改性处理 ,然后制成阻尼材料 ,用Oberst梁对其阻尼性能进行测试 ,结果表明 ,这种阻尼材料在相当宽的温度范围内具有较好的阻尼性能 。
Large amounts of used rubbers are discarded annually. A long time is needed for them to degrade naturally. This poses two major problems: environmental pollution and wastage of valuable rubber.. On the other hand, With the harm of vibration and noise widely recognized, desires to control them intensify. As an important means of vibration control, viscoelastic damping technology has advanced greatly. The need for cheap and high quanlity viscoelastic damping materials increases rapidly. This paper made a trial to use ground rubber tire (GRT) recovered from old tires to make damping materials. The GRT is treated specially first. Then it was pressed into slabs and vulcanized . Finally, the products was cut into test samples. Oberst beam was used to determine the loss factor β and storage modulus E ′. Results show that the damping materials exhibit good damping ability.
