The ir - spectrometry analysis results show that chemical combination exists between al - zr coupling agent and fiber - like palygorskite in the modified fiber - like palygorskite and the chemical combination between al - zr coupling agent and phenolic resin is the strongest relative to the other three coupling agents , so al - zr coupling agent can be selected to improve the bonding behavior between fiber - like palygorskite and phenolic resin in the friction material 红外光谱分析研究表明:偶联剂改性坡缕石中,铝锆偶联剂与坡缕石在改性过程中发生了相对强烈的化学键合;相对于其它三种偶联剂,铝锆偶联剂和丁腈改性酚醛树脂产生的化学键合最为强烈,因此可以认为铝锆偶联剂能够较好地改善摩擦材料中丁腈改性酚醛树脂和坡缕石纤维界面结合状况。
Monodisperse ( coefficient of variation 5 % ) polystyrene microspheres in the size range of 1 . 0 ~ 10 m are prepared by dispersion polymerization in ethyl alcohol reaction media using polyvinylpyrrolidone ( pvp ) as a steric stabilizer and 2 , 2 ' - azobisizobutyronitrile ( aibn ) as an initiator in suitable condition 摘要以聚乙烯吡咯烷酮为分散剂、无水乙醇为反应介质、偶氮二异丁腈为引发剂,采用分散聚合的方法,通过优化反应条件,成功制备出了粒径范围为1 ~ 10 m不同粒径级别的单分散(分散系数5 % )聚苯乙烯微球。
