Oil-filled and graphene oxide emulsion-filled co-coagulated rubber and preparation method thereof

Abstract

The invention discloses oil-filled and graphene oxide emulsion-filled co-coagulated rubber and a preparation method thereof. The co-coagulated rubber comprises the following main components by weight parts: 100 parts of rubber, 1-40 parts of oil, 1-20 parts of graphene oxide and 0.1-5 parts of an anti-ageing agent. The preparation method comprises the following steps: adding graphene oxide suspension liquid and the anti-ageing agent into rubber latex, and stirring at 30-60 DEG C for 0-30 minutes to obtain a mixture; adding emulsified oil into the mixture and stirring for 1-10 minutes; and adding a flocculant for flocculating, dewatering and drying to prepare the oil-filled and graphene oxide emulsion-filled co-coagulated rubber. The method is simple and feasible, low in cost and easy for industrialized production, and has good economic and social benefits. The oil-filled and graphene oxide emulsion-filled co-coagulated rubber prepared by adopting the method is relatively high in tensile strength, stress at definite elongation and tear strength and low in wear volume, and the characteristics of high reinforcement and high wear resistance of graphene oxide are fully reflected.

technical field [0001] The invention relates to the technical field of polymer-based nanocomposites, in particular to an oil-filled graphene oxide emulsion co-coagulated rubber and a preparation method thereof. Background technique [0002] Graphene oxide is an important derivative of graphene, and its structure is roughly the same as that of graphene. The polar functional groups on the two-dimensional base surface of graphene oxide, such as hydroxyl and epoxy groups and carbonyl and carboxyl groups at the edge, make oxidation Graphene has good hydrophilicity and is easy to form nanocomposites with some polar organic molecules and polymers. The hydrophilic groups of graphene oxide enhance the interfacial interaction between graphene oxide and matrix materials, improving the The mechanical properties of composite materials have broadened its development space, and are expected to become high-quality fillers for polymer nanocomposites. [0003] At present, the research on gra...

Problems solved by technology

When rubber / graphene oxide nanocomposites are prepared by emulsion flocculation or spray drying process, when the filling amount of graphene oxide is large, part of graphene oxide remains in the flocculation liquid, and the performance of the prepared composite material is poor.

However, when the mechanical mixing method is used, there will be phenomena such as flying dust, increased energy consumption, and uneven dispersion, so it is difficult to apply it to industrial production
