The present invention relates to a dipping material composition for cord fabric which is free of resorcinol and formaldehyde and production methods thereof comprising the steps of adding an acrylic resin containing a carboxylic acid group, adjusting pH value, adding an epoxy resin, adding a blocked polyisocyanate, adding a styrene butadiene latex and adding a styrene butadiene vinylpyridine latex into water, obtaining the dipping material, enabling the synthetic fiber and the rubber used in cord fabric reinforced rubber materials production to be attached to each other by providing an interface between the two said materials. Since the composition is formaldehyde-free, it is not as hazardous for human health as resorcinol-formaldehyde-latex (RFL) based systems and it is also environmentally friendly.
A dipping material composition characterized in that it comprises a functional acrylic polymer resin containing carboxylic acid, epoxy resin, blocked polyisocyanate, styrene-butadiene-latex (SBR) and styrene-butadiene-vinyl-pyridine latexes (VP), wherein in its content the acrylic polymer resin is used in a ratio of 0.5-10% by weight, the epoxy is 2-10% by weight, polyisocyanate is 5-17%, by weight styrene-butadiene latex is 5-17% by weight, styrene-butadiene-vinyl pyridine latex is 50-80% by weight.
