Bonded reinforced structures using amine resins

Claim 1

IN AN INTERGAL ELASTOMERIC COMPOSITE REINFORCED STRUCTURE WHEREIN A FILAMENTARY REINFORCEMENT ASSEMBLY IS ADHESIVELY SECURED TO AND WITHIN AN ELASTOMERIC MATRIX STRUCTURE BY AN ADHESIVE, THE IMPROVEMENT WHICH CONSISTS ESSENTIALLY OF AN ADHESIVE CONSISTING ESSENTIALLY OF THE COMBINATION OF RESORCINOL - FORMALDEHYDE - LATEX ADHESIVE DIP AND AN AQUEOUS SOLUTION OF POLYMIDE - POLYAMINE - EPICHLORHYDRIN ADDUCT, SAID POLYAMIDE - POLYAMINE BEING FORMED BY REACTION OF A POLYAMINE HAVING AT LEAST THREE AMINO GROUPS PER MOLECULE AND A SATURATED ALIPHATIC DICARBOXYLIC ACID CONTAINING 3 TO 10 CARBON ATOMS AT A REACTION TEMPERATURE OF ABOUT 110*C TO ABOUT 250*C THE AMOUNT OF SAID SATURATED ALIPHATIC DICARBOXYLIC ACID BEING SUFFICIENT TO REACT WITH AT LEAST TWO AMINE GROUPS OF THE POLYAMINE, THE POLYAMIDE - POLYAMINE BEING FURTHER REACTED WITH EPICHLOROHYDRIN AT A TEMPERATURE FROM ABOUT 25*C, TO ABOUT 110*C IN AN AQUEOUS SOLUTION AND AT A PH OF 7.5 TO 9.5, THE AMOUNT OF EPICHLOROHYDRIN BEING ABOUT 0.5 MOLE TO ABOUT 1.8 MOLE OF EPICHLOROHYDRIN PER MOLE POLYAMIDE, THE SOLUTION OF POLYAMIDE - POLYAMINE - EPCHLOROHYDRIN BEING ADJUSTED TO A SOLID CONTENT OF LESS THAN ABOUT 60% TO ABOUT 10 % AND A PH OF ABOUT 3 TO ABOUT 8, SAID ADHESIVE BEING APPLIED TO THE FILAMENTARY REINFORCEMENT PRIOR TO BONDING WITHIN THE ELASTOMERIC MATRIX, AND WHEREIN THE FILAMENTARY REINFORCEMENT ASSEMBLY IS SELECTED FROM THE GROUP CONSISTING OF GLASS METAL, RAYON, POLYESTER AND POLYAMIDE.
