Effects of atmospheric pollutants at high temperature on the adhesion of RFL‐coated tire cords to rubber

摘要

AbstractThe examination of treating oven pollutant effects on the adhesion of RFL‐coated polyester and nylon tire cord to rubber was conducted using a hot strip adhesion test. Ozone, ultraviolet light, and ozone–ultraviolet light were examined at 140°F. Nitrogen oxides, sulfur dioxide, and air were tested at 320°F. Ozone and ozone–UV (singlet molecular oxygen) systems were many orders of magnitude greater degradants than the other pollutants known to exist in the ovens. The remaining pollutants tested were ranked in order of degradation effect with NO2>NO ≫ SO2≡ air ≡ heat alone. The mechanism for adhesion loss involves addition to the olefinic double bonds to reduce unsaturation s
