METHOD FOR PROTECTING A TYRE AGAINST OZONE |
摘要 |
The present invention relates to a method for anti-ozone protection of at least a part of the outer surface of a vulcanized tire, where the composition of the tire is based on essentially unsaturated dienic elastomers. The present method comprises: (1) subjecting the surface of the vulcanized tire to a treatment in order to polarize and functionalize the elastomers of the surface; (2) applying at least one layer comprising an aqueous polyurethane dispersion to this treated surface; and (3) allowing this layer to dry until a protective coating is formed. The present invention further relates to a tire comprising an anti-ozone protective coating, where the protective coating is formed according to the method described above. |
