The invention discloses an environment-friendly rubber nano composite material for tires, and relates to the technical field of rubber, the rubber nano composite material is prepared by mixing the following raw materials based on 100 parts by weight of raw rubber components: 100.0 parts of natural rubber, 10.0-90.0 parts of carbon black, 1.0-80.0 parts of white carbon black and 1.0-20.0 parts of nanocrystalline cellulose, and a proper amount of a vulcanizing agent, an accelerant, an active agent and an anti-aging agent. Precipitated silicon dioxide, carbon black and nano microcrystalline cellulose are used as reinforcing filler, high reinforcing property is achieved, the viscous modulus is gradually reduced along with increase of the amount of carbon black replaced by nano microcrystalline cellulose due to the fact that waste paper nano microcrystalline cellulose is polar while natural rubber is non-polar, and the viscosity modulus is gradually reduced along with increase of the amount of carbon black replaced by nano microcrystalline cellulose. Due to the addition of the waste paper nano microcrystalline cellulose, the networking of the filler is reduced, so that the energy consumed by irreversible deformation is reduced, and the service life of the waste paper nano microcrystalline cellulose is further prolonged.
本发明公开了一种轮胎用的环保型橡胶纳米复合材料,涉及橡胶技术领域,所述橡胶纳米复合材料按生胶组分为100重量份计包括以下组分的原料混炼制备得到:天然橡胶100.0份,炭黑10.0—90.0份,白炭黑1.0—80.0份,纳米微晶纤维素1.0—20.0份,适量的硫化剂、促进剂、活性剂和防老剂。本发明通过使用沉淀二氧化硅、炭黑以及纳米微晶纤维素作为补强填充剂,具备高补强性,随着纳米微晶纤维素替代炭黑量的增加,粘性模量逐渐降低,原因是废纸纳米微晶纤维素是极性,而天然橡胶是非极性,因而废纸纳米微晶纤维素与胶料基体的相容性较差,其加入减轻了填料的网络化,使得不可逆形变损耗的能量减少,进而提高其使用寿命。
