Preparation and Performance Analysis of Composite Antioxidants for Sports Equipment
A reactive multifunctional rubber antioxidant was prepared by n-phenyl-p-phenylenediamine,dibutyltin dilaurate,allyl isothiocyanate and other materials in this study.The vulcanization process of SBR/SiO2 composites was optimized by this new antioxidant,the vulcanization promotion mechanism of which for SBR/SiO2 composites was introduced in detail.Finally,the vulcanization effect of this new antioxidant on SBR/SiO2 composites was tested by a rotatorless vulcanizer.It was found that the composite material was more helpful to shorten the scorch time and prolong the positive vulcanization time of SBR/SiO2 composites than the antioxidant commonly used in the field of sports equipment such as PPD and 4010NA,strengthen the cross-linking reaction of the composites.
