Abstract
A method of functionalising an elastomeric material, such as a rubber particle, is provided. The method comprises the functionalisation of an elastomeric material through the use of an ionic liquid based composition, which comprises a water soluble polymer, a cationic silicate component, and a salt of a vulcanization accelerator, together with a zinc compound, sulphur, and an accelerator. Rubber particles, for example particles from recycled rubber products, functionalised according to the method disclosed can successfully be utilised in virgin rubber masterbatches at concentrations not previously possible.
Claims16
A method of functionalising a vulcanised elastomeric material, the method comprising the steps of:
- a) providing a vulcanised elastomeric material having a surface to be functionalised,
- b) providing an ionic liquid based composition comprising a water soluble polymer, a cationic silicate component, and a salt of a vulcanization accelerator,
- c) providing a zinc compound, sulphur, and an accelerator,
- d) contacting the ionic liquid based composition of step b) and the components of step c) with the vulcanised elastomeric material surface,
- thereby to produce a functionalised elastomeric material.
