▎ 摘　　要

NOVELTY - Graphite oxide is ultrasonically dispersed in deionized water to obtain graphite oxide aqueous solution (A). White carbon black and coupling agent are ultrasonically dispersed into the aqueous solution to obtain aqueous solution (B). A binder is ultrasonically added to the solution (B) to obtain pre-treated aqueous solution. The pre-treated solution is ultrasonically dispersed and a flocculant is added into the composite emulsion and stirred to obtain flocculated gel. The gel is baked to obtain graphene/white carbon black/rubber nanocomposite. USE - Manufacture of graphene/white carbon black/rubber nanocomposite. ADVANTAGE - The graphene/white carbon black/rubber nanocomposite has high modulus, low rolling resistance, excellent water resistance, gas barrier property, self-healing property, excellent self-recovery capability of the graphite oxide, and is manufactured economically by a simple process. DETAILED DESCRIPTION - A graphene/white carbon black/rubber nanocomposite is manufactured by solution co-blending method or mechanical co-blending method. Graphite oxide is ultrasonically dispersed in deionized water at power of 0.1-1000 Kw, to obtain graphite oxide aqueous solution (A) with graphite oxide solid content of 0.01-20 wt.%. White carbon black and coupling agent or white carbon black modified by coupling agent are ultrasonically dispersed into the aqueous solution to obtain graphite oxide/white carbon black aqueous solution (B). A binder is ultrasonically added to the solution (B) to obtain pre-treated graphite oxide/white carbon black pre-treated aqueous solution. The pre-treated solution is ultrasonically dispersed to obtain stable composite emulsion. A flocculant is added into the composite emulsion and stirred to obtain flocculated gel. The gel is baked to at 60-300 degrees C to obtain graphene/white carbon black/rubber nanocomposite. Alternately, droplets of the composite emulsion are formed using a sprayer. The droplets are dewatered in a drying medium to obtain graphene/white carbon black/rubber nanocomposite. Alternately, a gasified flocculant is introduced into the drying medium in sprayer in order to carry out ion flocculation and dehydration at the same and produce the nanocomposite by solution co-blending method. Graphite oxide masterbatch is plastified in a roll mill or internal mixer, and white carbon black and coupling agent or white carbon black modified by the coupling agent are co-blended for 1-20 minutes to obtain graphene/white carbon black/rubber nanocomposite. Alternately, the white carbon black masterbatch is plastified and mixed with graphene oxide and binder to obtain the nanocomposite. Alternately, rubber is plastified and white carbon black, graphite oxide modified by coupling agent and binder, or white carbon black, coupling agent, graphite oxide and binder are co-blended to obtain the nanocomposite.
