摘要
通过双螺杆挤出机制备了聚丙烯/脂肪醇聚氧乙烯醚共混物。水接触角和黏结强度测试表明:脂肪族聚氧乙烯醚含量为6%时,共混物的接触角最小,黏结强度最大;DSC分析表明:脂肪醇聚氧乙烯醚对聚丙烯的熔融温度和结晶温度影响不大;力学测试分析表明:脂肪族聚氧乙烯醚含量为6%时,共混物的拉伸强度和弯曲强度与纯聚丙烯的相近,随其含量的增加,共混物力学性能逐渐降低。
PP/fatty alcohol polyoxyethylene ether blend was prepared by twin screw extruder. The test results of water contact angle and adhesive strength show that： when the content of fatty alcohol polyoxyethylene ether is 6%, the contact angle of the blend reaches the minimum value, the adhesive strength reachs the maximun value; the DSC analysis shows that fatty alcohol polyoxyethylene ether has little effect on the melting temperature and crystallization temperature; the test results of mechanical property show that： when the content of fatty alcohol polyoxyethylene ether is 6%, the tensile strength and flexible strength of the blend are similar to those of pure PP, with the increase of its content, the mechanical property decreases.
