Preparation method of oil-extended oxygenated graphene solution co-coagulation rubber

Abstract

The invention discloses a reparation method of oil-extended oxygenated graphene solution co-coagulation rubber. The oil-extended oxygenated graphene solution co-coagulation rubber mainly comprises, by weight, 100 parts of rubber, 1-80 parts of oil, 1-80 parts of graphene oxide, 0.1-5 parts of an antioxidant and 0.1-5 parts of a coupling agent. The preparation method comprises the following steps: adding graphene oxide, oil, the coupling agent and the antioxidant into a rubber solution, and stirring at a maintained temperature of 30-60DEG C for 1-30h; blending water steam in the above obtained mixture, and evaporating out and recovering solvent oil by using a distillation and separation device; and drying to prepare the oil-extended oxygenated graphene solution co-coagulation rubber. The method overcomes the disadvantages of non-uniform dispersion of a nano-filler, high energy consumption and poor physical performances of traditional mechanical blending methods, and has the advantages of simple preparation process, low cost and easy popularization. In a nanometer composite material prepared in the invention, graphene oxycarbide is uniformly dispersed in the rubber substrate, and has effective reinforcing and antistatic effects. The solution co-coagulation rubber prepared through the method has excellent performances, and has greatly improved mechanical performances, wear resistance and antistatic property.

Description

technical field [0001] The invention relates to the technical field of polymer-based nanocomposite materials, in particular to a method for preparing oil-filled graphene oxide solution co-coagulated rubber. Background technique [0002] Rubber is an important strategic material. Because of its special high elasticity, it is used in various fields of the national economy. However, the biggest disadvantage of rubber is its low strength, and it must be added with a reinforcing agent to be useful. For a long time, carbon black and silica have dominated as reinforcing agents for rubber. However, in addition to serious pollution, carbon black also depends on petroleum energy materials, which is expensive. However, silica is not only not ideal for reinforcing effect, but also expensive. Therefore, finding a rubber reinforcing material with low price, environmental protection and pollution-free and excellent reinforcing effect has always been the focus of research by scientific a...

AI Technical Summary

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

None of the above methods involve solution-based preparation of rubber / graphene oxide composites
