Abstract
The commonly used phenolic resin vulcanizing agents for rubber processing technology have some limitations. In this study, a new aldehyde teroctyl phenolic resin vulcanizing agent was synthesized from SP-1055 through a series of chemical reactions and tested for its efficiency in vulcanizing isoprene rubber (IR) at low dosages. The structure of the new phenolic resin was confirmed using infrared spectroscopy (FTIR) and 1H nuclear magnetic resonance (1H-NMR) spectroscopy. The results showed that the new phenolic resin exhibited excellent vulcanization properties and environmental protection characteristics, and the IR blended with the new phenolic resin vulcanizing agent showed higher tensile strength, elongation at break, and better recovery from prolonged extension than those of IR with traditional phenolic resin vulcanizing agents. The improvement is attributed to the replacement of the chain end hydroxyl with an aldehyde group in the new phenolic resin vulcanizing agent. The new phenolic resin vulcanizing agent has significant potential for future research and development and could be a promising alternative for medical rubber products.
