摘要：采用稀土铽氧化物（Tb4O7 ）、邻苯二甲酸氢钾（KHPht）和邻菲啰啉（Phen）合成铽三元配合物Tb（Pht）3Phen，通过机械共混、交联成型制备Tb（Pht）3Phen/NBR或Tb（Pht）3Phen/甲基乙烯基硅橡胶复合材料。扫描电子显微镜观察表明，机械混合后稀土配合物的粒径减小；荧光性能测试表明，当Tb（Pht）3Phen质量分数达到一定值时，复合材料的荧光性能比Tb(Pht)3Phen配合物好，且随着Tb(Pht)3Phen含量增大，复合材料的荧光强度增大，直到Tb(Pht)3Phen质量分数大于0.231时才出现“浓度猝灭”现象；Tb（Pht）3Phen质量分数相同时， Tb(Pht)3Phen /甲基乙烯基硅橡胶体系的荧光强度比Tb(Pht)3Phen/NBR体系大。

Abstract:The ternary complexes of rare earth terbium were systhesized with terbium oxide(Tb4O7),potassium hydrogen phthalate(KHPht) and orthophenanthroline(Phen).The Tb(Pht)3Phen/NBR or MVQ composites were prepared by mechanical blending and crosslinking.It was found by SEM that the particle sizes of complexes reduced by mechanical blending.The test results showed that the fluorescent property of composites,in which the content of Tb(Pht)3Phen reached a certain level,were better than that of Tb(Pht)3Phen complexes;the fluorescent intension of composites increased as the conten of Tb(Pht)3Phen increased,and the “fluorescent quenching” wouldn’t appear until the content of Tb(Pht)3Phen was greater than 23.1%;and the fluorescent intension of MVQ composite was greater than that of NBR composite.
Keywords:Tb(Pht)3Phen;NBR;MVQ;composite;fluorescent property

摘要：研究炭黑对反式1，4聚异戊二烯（TPI）及其并用胶性能的影响。结果表明，填充炭黑后，TPI混炼胶的结晶度和物理性能下降；采用粒径较小的炭黑补强的TPI硫化胶、NR/TPI和SBR/TPI并用硫化胶的物理性能较好，但动态性能较差，采用粒径较大的炭黑补强的这3种胶料的动态性能较好，但物理性能较差；采用炭黑N330补强的NR/TPI和SBR/TPI并用胶综合性能较好，可用作高速低滚动阻力轮胎胎面胶。

Abstract:The effect of carbon black on the properties of trans1,4polyisoprene (TPI) was investigated.The results showed that the crystallinity and physical properties of TPI mix decreased with addition of carbon black;the better physical properties,but the poorer dynamic properties of TPI,NR/TPI and SBR/TPI vulcanizates were obtained by using the carbon black with smaller particle size,in contrast,the better dynamic properties,but the poorer physical properties of above 3 vulcanizates were obtained by using the carbon black with larger particle size;and NR/TPI and SBR/TPI blends had better comprehensive properties,and could be used in the tread of high speed and low rolling resistance tire.
Keywords:TPI;NR;SBR;carbon black

摘要：研究普通和纳米二氧化钛与NR的相互作用。结果表明，二氧化钛与NR之间无化学作用，且对硫化体系与NR的化学作用产生屏蔽效应。二氧化钛的屏蔽效应、物理作用及补强作用均与其比表面积和吸油值呈正相关，与其粒径和pH值呈负相关。加入偶联剂NDZ101，可使纳米二氧化钛与NR的相互作用从全部是物理作用变为以化学作用为主（占757%）、物理作用为辅（占243%），填充NR硫化胶的拉伸强度约提高1倍。

Abstract:The interactions between common titanium dioxide or nanotitanium dioxide and NR were investigated.The results showed that the titanium dioxide didn’t react chemically with NR and had a shielding effect on the chemical reaction between curing system and NR;the shielding effect,physical action and reinforcement of titanium dioxide were directly proportional to its specific surface area and oil factor,and inversely proportional to its particle size and pH value;and the chemical action accounted for 75.7% of the whole interaction between nanotitanium dioxide and NR by adding coupling agent NDZ101 resulting in the increase of tensile strength for NR vulcanizate by 100%.
