摘要：Effect of maleic anhydride (MAH) modified carbon black prepared by solid state grafting in situ on the adhesion between nylon 66 cords and natural rubber was investigated by H pull out and flat belts-determination of ply adhesion test, and scanning electron microscopy (SEM). The results, which are cords bulk failure and rubber bulk failure in the two tests for unaged and aged samples employing MAH modified carbon black respectively, shown that good adhesion between cords and rubber interfaces is formed for the samples and kept in the two tests. This indicates that MAH modified carbon black can effectively enhance RFL dipped nylon 66 cords to natural rubber adhesion. In our viewpoint, the reason of the results is that active reaction groups introduced onto the carbon black surface by modification reacted with RFL; hence, integration effect was formed between dipped RFL nylon 66 cords and natural rubber interfaces. DMA results show that the modification of carbon black with MAH can effectively lower the rolling resistance of natural rubber vulcanizates. Mechanical property studies indicate carbon black modified with MAH is beneficial to keep higher tensile strength and elongation, especially for the aged vulcanizates.
