英文摘要The introduction of fillers/additives into polymer matrices is a practical and effective method for preparation of damping materials. In the current work, a designed 9,10-dihydro-9-oxa-10-phosphaphenanthrene 10-oxide-based oligosiloxane (DOPO-PMVS) was used as an additive to improve the damping properties of methyl phenyl vinyl silicone rubber (PVMQ). The preparation of high damping PVMQ elastomers with broad temperature range has been discussed, and the effect of silica, DOPO-PMVS, vinyl content of PVMQ, and frequency has been investigated. The damping mechanism involves hydrogen bonding interactions between DOPO-PMVS and silica instead of the PVMQ matrix. Also, the static mechanical and aging properties of PVMQ demonstrated a reasonably good performance. Interestingly, the dynamic mechanical analysis showed that via incorporation of 50 wt% silica and 10 wt% DOPO-PMVS, the loss tangents (tan delta) of PVMQ elastomers significantly improved in the temperature range of approximately 0-200 A degrees C and the maximum tan delta reached 0.55. Furthermore, the effective damping temperature ranges (tan delta ae 0.3) were more than 125, 100, and 40 A degrees C for PVMQ-1, PVMQ-2, and PVMQ-3 (5 Hz excepted) matrix, respectively. Also, even after aging at 160 A degrees C for 24 h, the effective damping temperature ranges remained at more than 100, and 70 A degrees C for PVMQ-1, and PVMQ-2 matrix, respectively. Hence, the elastomers provided decent damping properties and the study provides a novel and promising method for the preparation of high damping silicon rubbers with broad temperature range.
