| 中文摘要: |
| 考察白炭黑改性工艺对白炭黑胶料性能的影响，研究白炭黑表面原位接枝改性剂XM的应用。结果表明：用白炭黑预混炼改性工艺和白炭黑预处理改性工艺对白炭黑进行有机化改性，白炭黑胶料的性能提高；与白炭黑预混炼改性工艺胶料相比，白炭黑预处理改性工艺胶料的混炼工艺简单，形成的乙醇气体少，偶联剂Si69用量小，强度性能、耐磨性能、耐屈挠性能和抗刺扎性能提高，生热明显降低；采用改性剂XM改性白炭黑，胶料的加工安全性能和抗硫化返原性能提高，拉伸强度、拉断伸长率、撕裂强度和正硫化时的定伸应力提高，耐热老化性能较好。改性剂XM的应用为解决硅烷偶联剂产生乙醇气体和影响胶料加工安全性能提供了思路。 |
| 英文摘要: |
| The influence of silica modification on the properties of silica filled compound was investigated and the in-situ grafting modification using modifier XM was presented.The experimental testing results showed that，after organic modification of silica by pre-mixing process or pretreatment process，the properties of silica filled compound were improved.Compared with the pre-mixing process，when the silica was modified by pretreatment process，the mixing process of silica and rubber compound became simpler，producing quantity of ethanol gas was less，the needed amount of coupling agent Si69 was smaller，the strength properties，abrasion resistance，flex resistance and puncture resistance of the vulcanizates were better，and the dynamic heat build-up was lower. When the silica was modified by modifier XM，the processing property（scorch safety）and anti-reversion property of the compound were improved，the tensile strength，elongation at break and tear strength of the vulcanizates increased，and the heat aging resistance was better.Modification with modifier XM provided a solution to solve the problems of ethanol gas generation and reduced processing safety when the silane coupling agent was used. |
