摘要

The rubber composition with superfu00eccie exposed to moisture containing combination of su00eclica and resin of pegajosice specialized and tire with component thereof. A rubber composition containing silica having a non cured surface exposed to humidity where the rubber surface contains a combination of silica and a resin for the formation of pegajosice specialized.The silica exposed to moisture degrades necessary development of pegajosice for the composition of rubber. The specialized training of resin pegajosice neutralizes and significantly reduces the development of pegajosice reduction caused by the interaction of silica / moisture.In the same way, a process for preparing rubber - cured containing silica is provided by forming rubber through processing under high shear.The internal heat generation during extrusion or calendering to make the rubber composition reaches a high temperature followed by treatment of the surface of the rubber composition with moisture to cool the heated composition of rubber processed where the surface of the C Omposiu00e7u00e3o rubber contains said silica together with a specialized pegajosice resin.The invention also relates to the development of an assembly of non cured rubber components of which at least one of such components is a rubber composition containing silica exposed to moisture containing said resin pegajosice specialized training. This assembly is cured with sulfur in a suitable mold at an elevated temperature to form a side of the tyre.The formation of specialized pegajosice resin is a reaction product of t-butyl phenol and formaldehyde or product of t-butyl phenol and formaldehyde modified with vinyl chloride to the exclusion of sorbitan monostearate.
