Abstract
An improved rubber composition and method to create the improved rubber composition is achieved by milling reduced graphene oxide (“RGO”) in liquid rubber to induce a reduction of bulk density of the reduced graphene oxide while maintaining dispersibility in rubber without using a solvent-based process resulting in an industrially scalable process and an improved rubber composition.
Claims15
A reduced graphene oxide reinforced rubber composition comprising:
- a milled material comprising:
- a reduced graphene oxide milled with;
- a liquid rubber;
- an uncured rubber elastomer;
- an anti-degradant package;
- and
- a curing package.
The composition of any one of the above claims wherein the reduced graphene oxide and liquid rubber is milled in the absence of oxygen to form the milled material.
The composition of any of the above claims wherein the uncured rubber elastomer comprises styrene butadiene.
The composition of any of the above claims wherein the anti-degradant package comprises 6PPD.
The composition of any of the above claims wherein the curing package includes sulfur and an accelerator such as CBS.
The composition of any of the above claims wherein the composition is placed into a mold and heated to form a cured rubber product.
