摘要
进行耐低温耐臭氧易装配氯丁橡胶(CR)/丁腈橡胶(NBR)/聚氯乙烯(PVC)汽车等速万向节环保防尘罩共混胶的配方优化。胶料优化配方为:CR70,NBR(丙烯腈质量分数为0. 19)/PVC橡塑合金(以主体材料计)30,炭黑N55015,炭黑N99025,白炭黑8,硬脂酸1. 5,增塑剂TP-9525,内脱模剂935P1,莱茵蜡6541,防老剂4010NA2,防老剂NDBC1,防老剂MB0. 5,间接法氧化锌5,活性氧化镁3,硫黄/促进剂2. 8。优化配方胶料的物理性能、耐低温性能、耐臭氧性能、耐热老化性能和耐油性能满足用户耐低温耐臭氧环保防尘罩胶料标准要求,环保性能达到欧盟RoHS指令要求,生产成本较低,用其制备的防尘罩装配性能好。
The formulation optimization of CR/NBR/PVC for the environment-friendly and easyto-assemble dust cover of automobile isokinetic universal joint with low temperature resistance and ozone resistance was carried out. The optimum formulation of the compound was as follows:CR 70,NBR(mass fraction of acrylonitrile was 0.19)/PVC rubber and plastic alloy 30,carbon black N550 15,carbon black N990 25,silica 8,stearic acid 1.5,plasticizer TP-95 25,internal release agent 935 P 1,Antilux654 1,antioxidant 4010 NA 2,antioxidant NDBC 1,antioxidant MB 0.5,indirect zinc oxide 5,active magnesium oxide 3,and sulfur/accelerator 2.8. The physical property,low temperature resistance,ozone resistance,heat aging resistance and oil resistance of the optimized compound met user 's requirements of environment-friendly dust cover compound standard,and the production cost was low. The dust cover prepared by the optimized formulation compound had a good assembly performance.
