采用乳液聚合法制备单分散交联聚苯乙烯(PS)和α-甲基苯乙烯-丙烯腈共聚物(α-MS-AN)乳胶粒子,并研究其填充NBR和SBR胶料性能。结果表明,当引发剂KPS、乳化剂OP-10和SDS、交联剂DVB质量分别为单体质量的1%,3.3%,6.6%和20%时,可制备出平均粒径为43 nm、玻璃化温度(Tg)为125 ℃的PS纳米微球;当引发剂APS、乳化剂MS-1和交联剂DVB质量分别为单体质量的0.3%,2%~3%和15%时,可制备出平均粒径为47 nm、Tg为152 ℃的α-MS-AN纳米微球。两种填料在NBR和SBR胶料中的最佳用量均为30份;PS填充SBR胶料的物理性能优于其填充的NBR胶料;α-MS-AN填充的NBR胶料物理性能优于其填充的SBR胶料。 |

Monodisperse crosslinked polystyrene(PS) and α-methyl styrene-acrylonitrile(α-MS-AN) nano-latex particles were prepared by emulsion polymerization,and the physical properties of NBR and SBR filled with nano-latex particles were investigated.The results showed that the average particle size and Tg of PS were 43 nm and 125 ℃ respectively when the addition level of KPS,OP-10,SDS and DVB were 1%,3.3%,6.6% and 20%,respectively;the average particle size and Tg of α-MS-AN were 47 nm and 152 ℃ respectively when the addition level of APS,MS-1 and DVB were 0.3%,2%~3% and 15%,respectively.The optimum addition level of fillers was 30 phr;the physical properties of PS filled SBR was better than those of PS filled NBR;and the physical properties of α-MS-AN filled NBR was better than those of α-MS-AN filled SBR. |
