Abstract

The invention relates to an aramid fiber surface treatment solution as well as a preparation method and a use method thereof. The surface treatment solution is prepared from a pretreatment solution and a re-treatment solution. Aramid fibers impregnated with the treatment solution have effectively improved surface performance and improved adhesive performance, and treatment time is shortened.

Description

technical field [0001] The invention relates to the technical field of tire or conveyor belt production, in particular to an aramid fiber surface treatment liquid and a method for preparing and using the same. Background technique [0002] Aramid fiber was successfully developed by DuPont in the United States in the 1960s and commercialized in the 1970s. Due to its high strength and high modulus, it has been used in bulletproof vests, firefighting clothing, aerospace, skeleton materials and other fields. . However, the regular arrangement of aramid fiber molecular chains and the lack of active functional groups lead to poor adhesion between it and the matrix material, which greatly limits its application in the framework material. [0003] The present invention is based on predecessors' research, by changing the processing method of the aramid fiber, so as to improve the bonding performance of the aramid fiber and broaden its application field.
