一、tpv 8221-85m300微球發(fā)泡TPV復(fù)合材料制備及其性能：

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 8221-85m300廢舊輪胎橡膠粉填充改性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 8221-85m300環(huán)烷油填充EPDM/PP TPV的性能研究：

其次考察環(huán)烷油含量對(duì)EPDM/PP TPV 性能的影響,圖1 為環(huán)烷油充油量對(duì)EPDM/PPTPV熔體流動(dòng)速率的影響?由圖1可以看出,隨著充油量的不斷增加,EPDM/PPTPV的MFR從整體上來看也呈現(xiàn)了不斷增加的趨勢(shì)?當(dāng)充油質(zhì)量分?jǐn)?shù)低于20%時(shí),TPV的MFR增長(zhǎng)幅度緩慢且平穩(wěn),MFR數(shù)值基本維持在1.5左右;當(dāng)TPV中充油質(zhì)量分?jǐn)?shù)超過25%的時(shí)候,其MFR出現(xiàn)了大幅度升高的現(xiàn)象,當(dāng)充油質(zhì)量分?jǐn)?shù)達(dá)到40%的時(shí)候,MFR大幅度增加,達(dá)到5.7g/10min?

六、tpv 8221-85m300無鹵阻燃劑對(duì)TPV性能的影響：

結(jié)論:1)隨著無鹵阻燃劑用量的增加，材料的硬度和壓縮永久形變呈現(xiàn)先減小然后增加的變化趨勢(shì)，其原因與無機(jī)填料的硬化效應(yīng)和分散劑的軟化效應(yīng)有關(guān)。2)隨著阻燃劑用量的增加，拉伸強(qiáng)度和100％定伸強(qiáng)度降低，斷裂伸長(zhǎng)率降低。3)隨著剪切速率的增加，材料的表觀黏度降低，呈現(xiàn)剪切變稀現(xiàn)象，添加25％ 阻燃劑的黏度較純TPV略有降低，超過35％后黏度增加。4)當(dāng)阻燃劑用量≥35％ 時(shí)，1．6 mm可達(dá)到V一1，3．2 mm可達(dá)到V-()，具有較好的防吸水性能，能滿足建材和電線電纜行業(yè)的要求。

八、廣業(yè)視角-- PS價(jià)格穩(wěn)定 市場(chǎng)成交清淡   tpv 8221-85m300

04月26日訊

  一.價(jià)格走勢(shì)

    PS市場(chǎng)整體相對(duì)穩(wěn)定，商家心態(tài)不佳，多隨行出貨，廠家部分做出小額讓利初成成交，但市場(chǎng)依舊表現(xiàn)平淡。

    PS市場(chǎng)價(jià)格穩(wěn)定，下游接貨意愿不佳。據(jù)生意社數(shù)據(jù)顯示：4月26日PS525價(jià)格在10200元/噸左右。

  二.行情分析

    PS市場(chǎng)行情：廣州石化PS出廠價(jià)格，525報(bào)價(jià)為10100元/噸。湛江中美PS出廠價(jià)格，525報(bào)價(jià)為10250元/噸。中信國(guó)安PS出廠價(jià)格，525報(bào)價(jià)為10200元/噸。
