Abstract

The invention discloses an aramid fiber surface treatment fluid. The aramid fiber surface treatment fluid comprises the following components in parts by weight: a pretreatment liquid: 160 to 180 partsof methylbenzene, 16 to 18 parts of polyaryl polymethylene isocyanate, 4 to 6 parts of epoxy resin, 0 to 4 parts of coumarone resin, 0 to 2 parts of chloridized natural rubber and 0 to 3 parts of nitrile rubber; a retreatment liquid: 180 to 200 parts of deionized water, 10 to 15 parts of water-soluble resorcinol-formaldehyde resin, 10 to 15 parts of 25% to 30% of ammonia water, 180 to 200 parts of butadiene-vinylpyridine copylymer latex and 10 to 13 parts of 36% to 40% formaldehyde. By using the aramid fiber surface treatment fluid, the surface performance is effectively improved, and the bonding performance of aramid fiber is improved.

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 preparation method thereof. Background technique [0002] Aramid fiber was successfully developed by DuPont of 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, and framework materials. . However, the aramid fiber has a regular molecular chain arrangement and few active functional groups, resulting in poor adhesion to the matrix material, which greatly limits its application in framework materials. [0003] Aramid is a new type of special high-performance industrial fiber formed by rigid molecular chains with high strength, high modulus, high temperature resistance and small deformation. However, aramid fiber has a unique "skin-core" structure. The core is composed of many rod-shaped mo...
