摘要
研究了防老剂MB用量对三元乙丙橡胶耐老化性能的影响,研究表明,在防老剂2246/MB体系中,防老剂MB用量对共混胶硫化特性基本无影响;当防老剂MB用量为1.5份时,共混胶老化后性能及保持率均较好,老化过程中拉伸强度及扯断伸长率均较高。
This paper studied the effect of the amount of antigaer MB on the aging resistance for EPDM rubber. Studies have shown that in the antigaer 2246/MB system, the amount of antigaer MB has no effect on the vulcanization characteristics of the blended rubber; When the amount of antigaer MB is 1.5, the performance and retention rate of the blended rubber are good after aging, and the tensile strength and elongation at break are both high in the aging process.
