一、tpv 271-55微球发泡TPV复合材料制备及其性能：

The hot air aging results of 110℃×1 000hand 135℃×168hindicated that the microsphere foamed TPV composites had excellent heat aging properties.The hardness change was only 2,the tensile strength retention rate was as high as 93.5%and 95.7%,and the elongation at break retention was 80.8%and 85.9%,respectively compared with the TPV performance before aging.The dimensional shrinkages of the microsphere foamed TPV composites in the Ldirection and the Tdirection after aging were less than 1.0%.SEM of quenching section studies showed that when the screw rotation speed was 160r/min,the microbubble forming agent had larger cell size and uniform distribution,and the compatibility between the expanded microsphere foaming agent and the substrate TPV was better,and the micro-foamed TPV composite material had a superior extrusion appearance and comprehensive physical and mechanical properties.

Key words:microsphere foaming agent;TPV;thermoplastic elastomer;hot air aging

二、tpv 271-55废旧轮胎橡胶粉填充改性TPV的研究：

Study on Filling and Modified TPV of Waste Tire Rubber Powder

LV Huai - xing TU Zhong – dan (GEM Co. , Ltd , Shenzhen Guangdong 518101 , China )

【Abstract】The TPV /WGRT thermoplastic elastomer was prepared on an internal mixer , and the effect of the amount of WGRT added and the amount of additives added on the performance of the matrix was investigated . The results showed that when WGRT was added separately , the tensile strength and modulus at 100% elongation of the matrix decreased gradually with the increasing of the addition amount , and the Shore A hardness gradually increased . When the addition amount of M603 compatibilizer increased , the tensile strength and modulus at 100% elongation of the matrix increased gradually , and then tend to be stable under adding different amounts of WGRT.

五、tpv 271-55环烷油填充EPDM/PP TPV的性能研究：

其次考察环烷油含量对EPDM/PP TPV 性能的影响,图1 为环烷油充油量对EPDM/PPTPV熔体流动速率的影响?由图1可以看出,随着充油量的不断增加,EPDM/PPTPV的MFR从整体上来看也呈现了不断增加的趋势?当充油质量分数低于20%时,TPV的MFR增长幅度缓慢且平稳,MFR数值基本维持在1.5左右;当TPV中充油质量分数超过25%的时候,其MFR出现了大幅度升高的现象,当充油质量分数达到40%的时候,MFR大幅度增加,达到5.7g/10min?

六、tpv 271-55无卤阻燃剂对TPV性能的影响：

结论:1)随着无卤阻燃剂用量的增加，材料的硬度和压缩永久形变呈现先减小然后增加的变化趋势，其原因与无机填料的硬化效应和分散剂的软化效应有关。2)随着阻燃剂用量的增加，拉伸强度和100％定伸强度降低，断裂伸长率降低。3)随着剪切速率的增加，材料的表观黏度降低，呈现剪切变稀现象，添加25％ 阻燃剂的黏度较纯TPV略有降低，超过35％后黏度增加。4)当阻燃剂用量≥35％ 时，1．6 mm可达到V一1，3．2 mm可达到V-()，具有较好的防吸水性能，能满足建材和电线电缆行业的要求。

八、广业视角-- 4月24日PET涨跌观点   tpv 271-55

04月24日讯

  商品名称：PET

  最新价格(4月124日)：8662.50元/吨

  分析要点：原料PTA行情窄幅震荡，同时原料乙二醇价格疲软下跌，PET成本端支撑面一般。国内PET库存处于低位，暂无销售压力，厂家长远期订单让利可谈。但近期下游采购商观望态度为主，实际成交量不高，市场交易氛围清淡。致使国内PET价格疲软下跌，预计短期内国内PET瓶级厂家主流报价范围8500-8700元/吨。
