Abstract

The invention discloses a kind of friction-resistant quick-drying odorless ink and preparation method thereof, relate to the technical field of ink. The present invention uses graphite as raw material, sequentially utilizes H2O2 hot air flow, 1,4-butene glycol air flow to carry out secondary crushing, realizes the nanoization of graphite, and can react with modified polyurethane, propylene compound and oxygen in air to polymerize, makes writing quickly completely dry by liquid material, has excellent quick-drying property, forms dense film-like structure after quick-drying simultaneously, wraps graphite nanoparticles inside, and graphite itself has self-lubricating property, therefore produces better synergistic effect, improves the wear-resistant effect of ink. In addition, the present invention introduces photochromic group into polyurethane molecular chain, compared with adding photochromic agent alone, can prolong the effective period of photochromism.
