Abstract
The present invention relates to a dipping solution for cord fabrics and a production method thereof comprising the steps of adding acrylic resin (polymer) into water (11), adjusting pH value (12), adding epoxy to the composition (13), adding polyisocyanate to the composition (14), adding latex to the composition (15), obtaining the dipping material (16); 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 two said materials; not as hazardous as RFL for human health and also being environmental friendly.
Claims10
A method for producing a RFL (resorcinol-formaldehyde) free dipping solution for cord fabrics comprising the steps of
- (a) adding acrylic polymer resin into water,
- (b) raising pH,
- (c) adding epoxy,
- (d) adding polyisocyanate,
- (e) adding latex, wherein the latex comprises butadiene, styrene and vinyl monomers, and is not the acrylic polymer, and wherein the solid amount inside the latex is between 35-45% by weight, and
- (f) obtaining the dipping solution,
- wherein the acrylic polymer resin has carboxylic acid functionality and wherein the dipping solution comprises the acrylic polymer resin in an amount of 1-7% by weight, the epoxy in an amount of 0.6-2.5% by weight and the polyisocyanate in an amount of 6-21% by weight.
