Abstract

Poly(acrylic acid)/modified attapulgite/zinc oxide composite (PAA/BF-ATP/ZnO) was prepared by acrylic acid, modified attapulgite (BF-ATP), triethoxy vinyl silane modified ZnO using in situ polymerization, and used in cotton fabric for improving the flame-retardant and UV protection properties. FT-IR and TEM results showed that PAA/BF-ATP/ZnO composite was successfully prepared. The stability, percent conversion, solid content and rotational viscosity of the composites with different ZnO content were investigated. The results showed that the conversion of composites was all above 98%, and these composites also had good stability, when the content of ZnO was 0.2–1%. Composite was loaded onto the cotton fabric by the dip-pad-dry method. The results showed that the thermal and flame retardant properties of cotton fabric were improved after treatment with the PAA/BF-ATP/ZnO, the LOI of the cotton fabrics with PAA/BF-ATP/ZnO was reached to 24.4%, which was 1.3% higher than that of PAA/BF-ATP treated cotton fabric. The burning rate was reduced to 0.68 mm/s, which was 0.24 mm/s lower than that of PAA/BF-ATP treated cotton fabric.

基于聚丙烯酸/改性凹凸棒土/氧化锌的棉织物阻燃复合材料

摘要

采用丙烯酸，改性凹凸棒石（BF-ATP），三乙氧基乙烯基硅烷改性ZnO原位聚合制备聚丙烯酸/凹凸棒石/氧化锌复合材料（PAA / BF-ATP / ZnO）。用于改善阻燃和紫外线防护性能。FT-IR和TEM结果表明成功制备了PAA / BF-ATP / ZnO复合材料。研究了不同ZnO含量的复合材料的稳定性，转化率，固含量和旋转粘度。结果表明，当ZnO含量为0.2-1％时，复合材料的转化率均高于98％，并且这些复合材料还具有良好的稳定性。通过浸涂-干燥法将复合材料加载到棉织物上。结果表明，采用PAA / BF-ATP / ZnO处理后，棉织物的热，阻燃性能得到改善，采用PAA / BF-ATP / ZnO处理的棉织物的LOI达到24.4％，为1.3。比PAA / BF-ATP处理的棉织物高％。燃烧速率降低到0.68 mm / s，比PAA / BF-ATP处理的棉织物的燃烧速率低0.24 mm / s。
