摘要: 选择环保型水性聚氨酯(WPU)作成膜物、低成本竹炭(BC)作功能助剂,通过BC改性及优化配方制备了WPU/BC高性能抗静电涂膜,研究了BC改性剂种类、用量,BC用量、粒度及分散时间等因素对该功能涂膜电性能的影响。结果表明,硅烷偶联剂γ-APTES是效果最好的BC改性剂,γ-APTES改性的WPU/BC功能涂膜的适宜制备工艺条件为:γ-APTES用量为BC的2 %,25?mBC的用量为20份,分散40 min,此条件下制备的涂膜体积电阻率为1.7×104 Ω·cm,铅笔硬度为4H,冲击强度为73 kg.cm,耐洗刷性为11350次。

Abstract: Water-borne polyurethane(WPU) was filled with bamboo charcoal (BC) forming antistatic paint film. The effect of BC loading, BC modifier, BC granularity, and mixing time on the properties of the film was investigated. γ-APTES was found a good modifier for BC. When the content of γ-APTES was 2 wt% of BC, BC content was 20 phr, BC granularity was 25?m, and mixing time was 40 min, the obtained WPU/BC film a volume resistivity of 1.7×104 Ω·cm, a pencil hardness of 4H, an impact strength of 73 kg.cm, a washability of 11350 times.
