STUDY ON MECHANICAL PROPERTIES AND THERMAL PROPERTIES OF SA TYPE TRANSPARENT NYLON/NANO-SiO2 COMPOSITE
【摘要】 以SA型透明尼龙(PA)为基体,以KH-550处理的纳米S iO2为填料,采用熔融共混法制备了SA型透明PA/纳米S iO2复合材料。用微机控制电子万能试验机及简支梁冲击试验机测试了其力学性能;用维卡软化温度测定仪及差示扫描量热仪测试了其热性能。结果表明,SA型透明PA/纳米S iO2复合材料的弯曲弹性模量、弯曲强度和拉伸弹性模量均有较大提高,而拉伸强度、缺口冲击强度稍有降低;SA型透明PA/纳米S iO2复合材料的耐热性有明显提高。
【Abstract】 SA type transparent nylon(SATPA)/nano-SiO2 composites were prepared by using melt blending method with SATAP as matrix material,nano-SiO2 treatmented with KH-550 as modifier.The mechanical and thermal properties of SATPA/SiO2 composites were studied.The results showed that the flexural strength,flexural modulus and tensile modulus of composites were superior to those of SATPA,while the tensile strength and impactstrength decreased lightly;the thermal properties of composites were markedly superior to those of SATPA.Both Vicat softening temperature and Tg of composites were higher than that of SATPA.
