The invention discloses a wear-resistant rubber composition for an active air spring and a preparation method and application of the wear-resistant rubber composition. Raw materials of the rubber composition comprise chloroprene rubber and auxiliaries, the auxiliaries comprise a vulcanizing agent and wear-resistant components, and the wear-resistant components comprise carbon black and polyethylene powder; the iodine absorption value of the carbon black is 50-100mg/g, the oil absorption value of the carbon black is 80-110mL/100g, the specific surface area of the carbon black is 50-110m/g, the addition amount of the carbon black is less than or equal to the addition amount of the polyethylene powder, and the raw materials are subjected to mixing and thin-passing plastication during preparation; according to the invention, unexpected excellent performances such as high wear resistance and the like can be realized, the wear resistance between outer rubber layers of an air spring group is greatly improved, the damage risk is reduced, the rubber layer can be applied to a bag skin for an active air spring, the structure of the active air spring is improved, and the service life of the active air spring is prolonged. The height and rigidity of the air spring body can be rapidly adjusted, an air compressor is not needed, and noise in the air compression process is effectively reduced.
本发明公开了一种主动式空气弹簧用耐磨胶料组合物及其制备方法和应用,该胶料组合物的原料包括氯丁橡胶、助剂,助剂包括硫化剂、耐磨组分,耐磨组分包括炭黑和聚乙烯粉末;炭黑的碘吸收值为50‑100mg/g,油吸收值为80‑110mL/100g,比表面积为50‑110m²/g,炭黑的添加量小于等于聚乙烯粉末的添加量,制备时将各原料混合混炼和薄通塑炼;本发明可实现出乎意料的高耐磨性等优异性能,大大地提高了空气弹簧组外层胶之间的耐磨能力,降低了破损风险,可将其应用于主动式空气弹簧用的囊皮,同时还对主动式空气弹簧的结构进行改进,可实现空簧本体高度以及刚度的迅速调整,无需空压机,有效地减少空气压缩过程中的噪音。
