Preparation and Thermal-Resistant Performance of Silicon Rubber

Abstract:

Heat vulcanized silicon rubber was prepared by mixing technology. The influences of factors on silicon rubber performance were investigated such as raw rubber dosage, thermal-resistant additive dosage and process conditions. The results show that the optimal formula is as follows: 28.8phr raw rubber containing 0.23 vinyl group, 0.4phr white carbon black dispersant, 10phr vapor white carbon black, 0.5phr iron oxide, 0.7phr zinc oxide, 0.99phr thermal-resistant additive, 0.4phr accelerator DM and 0.6phr benzoyl peroxide. After placed for 24h, the mixture underwent two-step vulcanization (127°C×10.0MPa×6min and 200°C×4h). The thermal-resistant performance of silicon rubber was dramatically improved by thermal-resistant additive.
