摘要:

研究了不同聚对苯二甲酸乙二醇酯(PET)和聚对苯二甲酸丁二醇酯(PBT)配比对阻燃增强PET/PBT合金表面浮纤的影响。采用二次元影像测试仪和目测的方式,半定量地表征表面浮纤。结果表明,随着PBT含量的增加,表面浮纤逐渐减弱;当PET和PBT质量比接近1∶1时,材料表面质量最好;进一步提高PBT含量时,表面浮纤现象又逐渐严重;阻燃增强PBT材料的表面浮纤现象比阻燃增强PET材料轻。

Abstract:

In this paper, the effect of mas ratio of PET to PBT on the surface of flame?retardant reinforced PET/PBT Alloy was investigated. The surface fiber?floating phenomenon was characterized semi?quantitatively using a two?dimensional image tester and visual inspection. The results indicated that the surface fiber?floating phenomenon became less serious with an increase in the PBT content. When the ratio of PET to PBT was close to 1:1, the fiber floating became weakest. When the PBT content further increased, the fiber floating became worse. The flame retardant reinforced PBT exhibited weaker fiber floating than the flame retardant reinforced PET.
