Abstract:
A method of producing a textile-reinforced rubber composite comprising the sequential steps of(a) providing a textile substrate; (b) contacting the textile substrate with a composition comprising either (i) a mixture of at least two different silane compounds, one compound selected from (I) and the other selected from (II); wherein (I) and (II) include the following: (I) aminosilanes selected from the group consisting of â€ƒwherein R is C1-C6 alkyl, R1 is an amine functional group, and Râ€² is an alkyl- or aromatic-acyl group; (II) organo-functional silanes selected from the group consisting of â€ƒwherein R is C1-C6alkyl, R2 is a moiety having an affinity for rubber selected from the group consisting of a mercapto moiety, a sulfide moiety, an isocyanate moiety, an epoxy moiety, a pyridine moiety, a hydrophobic saturated alkyl moiety, and a moiety having a carbon-carbon double bond, and Râ€² is defined as for (I) above; or (ii) at least one functional silane containing both an amine functional group and a moiety having an affinity for rubber selected from the group consisting of a mercapto moiety, a sulfide moiety, an isocyanate moiety, an epoxy moiety, a pyridine moiety, a hydrophobic saturated alkyl moiety, and a moiety having a carbon-carbon double bond; (c) heating the textile substrate at a temperature of from about 120 to about 250Â° C. for from about 15 seconds to about 5 minutes; (d) optionally coating or impregnating the textile substrate with an RFL composition; (e) combining at least a portion of the resulting treated textile substrate with a rubber composition to from a textile-reinforced rubber composite; and (f) curing the textile-reinforced rubber composite.
