The invention discloses a high-performance colored special rubber material as well as a preparation method and application thereof, and belongs to the technical field of colored rubber materials and rubber tracks. The formula of the high-performance colored special rubber material comprises the following raw materials: 100 parts of natural rubber, 50-75 parts of white carbon black, 0.05-1.0 part of carbon black, 2-6 parts of an anti-aging agent composition, 1-3.5 parts of insoluble sulfur, 1-4 parts of an accelerant and 3-8 parts of a coupling agent. Wherein the anti-aging agent composition is prepared from an anti-aging agent 2246, an anti-aging agent MB and an anti-aging agent SP-C, and the mass ratio of the anti-aging agent 2246 to the anti-aging agent MB to the anti-aging agent SP-C is (1.5 to 2.5 According to the invention, the formula of the colored rubber material is optimized and improved, the use amount of the natural rubber is increased while the use amount of the styrene-butadiene rubber is canceled, the anti-aging agent 2246, the anti-aging agent MB and the anti-aging agent SP-C are adopted to construct a miscellaneous synergistic protection system with better protection performance, and a reinforcing system and a vulcanization system are properly adjusted. The physical and mechanical properties, the hot air aging property, the weather aging property and the fatigue resistance of the prepared colored rubber material are greatly improved, and the use requirements of the colored engineering machinery rubber track can be well met.
本发明公开了一种高性能彩色特种胶料及其制备方法与应用,属于彩色胶料及橡胶履带技术领域。本发明高性能彩色特种胶料配方原料包括:天然橡胶100份、白炭黑50‑75份、炭黑0.05‑1.0份、防老剂组合物2‑6份、不溶性硫磺1‑3.5份、促进剂1‑4份、偶联剂3‑8份;其中,防老剂组合物由防老剂2246、防老剂MB、防老剂SP‑C组成,三者质量比为(1.5‑2.5):(0.8‑1.2):(0.7‑1.1)。本发明对彩色胶料进行配方优化改进,取消丁苯橡胶的使用同时增加天然橡胶用量,采用防老剂2246、防老剂MB、防老剂SP‑C构建防护性能更好的杂协同防护体系,并适当调整补强体系与硫化体系。本发明制备得到的彩色胶料物理机械性能、热空气老化性能、天候老化性能及耐疲劳性能大幅提高,能够很好的满足彩色工程机械橡胶履带的使用需求。
