摘要:
研究了丁腈橡胶(NBR)3604和2707生胶门尼黏度和结合丙烯腈质量分数对硫化胶的拉伸强度、扯断伸长率及溶胀度的影响。结果表明,随着生胶门尼黏度的增加,NBR 3604和NBR 2707硫化胶的拉伸强度和扯断伸长率均呈线性增加的趋势,而溶胀度则均呈线性减小的趋势;NBR 3604和NBR 2707生胶门尼黏度每增加1个单位,硫化胶的拉伸强度分别增加0.15 MPa和0.02 MPa,扯断伸长率分别增加1.13%和1.30%,溶胀度分别减小0.02%和0.21%。随着结合丙烯腈质量分数的增加,NBR 3604和NBR 2707硫化胶的拉伸强度均呈线性增大的趋势,而扯断伸长率和溶胀度则均呈线性减小的趋势;NBR 3604和NBR 2707结合丙烯腈质量分数每增加1%,硫化胶的拉伸强度均增加0.04 MPa,扯断伸长率分别减小0.08%和2.77%,溶胀度分别减小0.06%和0.25%。
Abstract:
The effects of Mooney viscosity (MV) of raw rubbers and mass fraction of bound acrylonitrile (wAN) of nitrile rubber (NBR) 3604 and NBR 2707 on tensile strength (Ts), elongation at break (Eb) and degree of swelling (Ds) of the vulcanizates were studied. The results showed that with the increase in MV of raw rubbers, Ts and Eb of NBR 3604 and NBR 2707 vulcanizates all showed a linear increasing trend, whereas their Ds all showed a linear decreasing trend; when MV of raw rubbers of NBR 3604 and NBR 2707 increased by 1 unit, Ts of their vulca-nizates increased by 0.15 MPa and 0.02 MPa respectively, Eb of their vulcanizates increased by 1.13% and 1.30% respectively, and Ds of their vulcanizates decreased by 0.02% and 0.21% respectively. With the increase in wAN, Ts of NBR 3604 and NBR 2707 vulcanizates all showed a linear increasing trend, whereas Eb and Ds of their vulcanizates all showed a linear decreasing trend; when wAN of NBR 3604 and NBR 2707 increased by 1%, Ts of their vulcanizates all increased by 0.04 MPa, Eb of their vulcanizates decreased by 0.08% and 2.77% respectively, and Ds of their vulcanizates decreased by 0.06% and 0.25% respectively.
