GLASS FIBER REINFORCED ELASTOMERS

摘要

The improvement in the bonding relationship between glass fibers and elastomeric materials in the manufacture of glass fiber reinforced elastomeric products wherein the glass fibers are previously sized with a size consisting essentially of an anchoring agent such as an aminosilane, an epoxy silane or a Werner complex compound wherein the carboxylate group of the Werner complex compound contains either an amino group or an epoxy group and impregnated in bundle form with an impregnant consisting essentially of a natural rubber and resorcinol-formaldehyde resin and in which the impregnating composition may be employed as the size to provide the desired loading of material on the glass fiber surfaces without subsequent impregnation of the fiber bundle when the size composition is formulated of the natural rubber latex - resorcinol-formaldehyde resin plus an organo silicon compound or Werner complex compound wherein the organo silicon compound is formed of an amino silane or epoxy silane and wherein the carboxylato group of the Werner complex compound contains either an amino group or an epoxy group.
