The invention relates to the technical field of rubber products, and particularly discloses an automobile sealing strip corner connecting material, an automobile sealing strip assembly and a preparation method. According to the automobile sealing strip corner connecting material provided by the invention, specific low Mooney ethylene propylene diene monomer and high ENB high-resistance ethylene propylene diene monomer are used together, high-resistance carbon black BC1004 is matched as a reinforcing material, liquid ethylene propylene diene monomer Triene 67 is used as a plasticizer, a nano reinforcing agent PF81S is used as a filler, and modified lignin is added, so that the bonding effect of the corner connecting material is improved; the prepared sealing strip corner connecting material has the performance requirements of high resistance, vulcanization manufacturability, hardness, strength and the like, paraffin oil is not added into the whole system, the processing technology performance of the corner connecting material is guaranteed, rapid vulcanization and stable production of the corner connecting material are achieved, in addition, the whole system does not contain nitrosamine substances, the environment friendliness is higher, and the sealing strip corner connecting material is suitable for large-scale popularization and application. And the material has a relatively high application prospect in the field of automobile sealing strip corner connecting materials.

    本发明涉及橡胶制品技术领域,具体公开一种汽车密封条接角材料、汽车密封条总成及制备方法。本发明提供的汽车密封条接角材料通过采用特定的低门尼三元乙丙橡胶和高ENB高电阻三元乙丙橡胶并用,配合高电阻炭黑BC1004作为补强材料、液体三元乙丙橡胶Trilene 67作为增塑剂、纳米补强剂PF81S作为填料,以及添加改性木质素改善接角材料的粘结效果,使得制备的密封条接角材料兼具高电阻、硫化工艺性和硬度、强度等性能要求,且整个体系中不加入石蜡油,保证了接角材料的加工工艺性能,有利于实现接角材料的快速硫化和稳定生产,除此之外,整体体系不含亚硝胺类物质,环保性更高,在汽车密封条接角材料领域具有较高的应用前景。
