Method of bonding synthetic fibrous material to rubber using an aqueous dispersion-type adhesive

Abstract

Abstract 1. A METHOD OF BONDING A SYNTHETIC FIBROUS MATERIAL TO RUBBER, WHICH COMPRISES COATING A SYNTHETIC FIBROUS MATERIAL WITH AN AQUEOUS DISPERSION COMPRISING (A) A NOVOALK RESIN DERIVED FROM 1 MOL OF A MONOHYDROXY BENZENE HAVING TWO MORE FUNCTIONAL GROUPS OR ITS DERIVATIVE SELECTED FROM THE GROUP CONSISTING OF: PHENOLS OF FORMULA (1) 2-R1,3-R2,4-R3,5-R4,6-R5-PHENOL WHEREIN EACH OF R1 THROUGH R5 IS A HYDROGEN ATOM, AN ALKYL GROUP CONTAINING 1 TO 15 CARBON ATOMS, OR A HALOGEN ATOM, AND AT LEAST TWO OF R1, R3, AND R5 ARE HYDROGEN ATOMS; MONOHYDROXY BENZENE DERIVATIVES OF FORMULA (2) R6-PHENOL WHEREIN R6 IS A GROUP SELECTED FROM A HYDROXYPHENOL GROUP AND -C(-R7)(-R8)-PHENYLENE-OH WHEREIN EACH OF R7 AND R8 IS A HYDROGEN ATOM OR AN ALKYL GROUP HAVING 1 TO 10 CARBON ATOMS, IN WHICH THE RATIO OF THE NUMBER OF BENZENE RINGS TO THAT OF HYDROXYL GROUPS IN THE MOLECULE IS 1:1, AND FROM 0.3 TO 1 MOL OF FORMALDEHYDE, (B) 0.05 TO 1 PART BY WEIGHT PER PART OF SAID RESIN (A), OF A RESOLE-TYPE PRECONDENSATE DERIVED FROM 1 MOL OF RESORCINOL AND 1 TO 6 MOLS OF FORMALDEHYDE, AND (C) 1/2 TO 9 PARTS BY WEIGHT PER PART BY WEIGHT OF THE SUM OF SAID RESIN (A) AND PRECONDENSATE (B), OF A RUBBER LATEX, CURING THE COATING AT A TEMPERATURE OF AT LEAST 100*C. BUT NOT HIGHER THAN THE SOFTENING POINT OF THE FIBROUS MATERIAL, AND BONDING THE FIBROUS MATERIAL TO AN UNVULCANIZED RUBBER MATERIAL WHILE VULCANIZING.
