摘要
采用铝掺杂四针状氧化锌晶须作为功能性填料制备得到多功能水性聚氨酯涂料,其具有良好的抗静电性能、高耐磨性能以及优异的自清洁功能。采用硅烷偶联剂制备了分散性良好的晶须,并研究了晶须含量对涂层抗静电性能和耐磨性能的影响。当晶须含量为8%时,涂层的体积电阻率和表面电阻率分别从10^(15)Ω·cm和10^(16)Ω降低至10~7Ω·cm和10~7Ω,且涂层的磨耗量从22 mg降低至12 mg;此外,铝掺杂氧化锌晶须/聚氨酯涂层具有光催化功能和一定的自清洁功能。
Aluminum-doped tetrapod-shaped zinc oxide whisker is used as functional filler to prepare water-borne PU coatings, which are of good static electricity resistance, high abrasion resistance and perfect self-cleaning function. Silicone coupling agent is adopted to prepare crystal whisker of good dispersion and we have studied the influence of the content of crystal whisker on the static electricity resistance and abrasion resistance. With the crystal whisker of 8%, when the volume resistivity and the surface resistivity decrease from 10^15 Ω. cm and 10^16 Ω to 10^7 Ω cm and 10^7 Ω, the abrasion loss of film decreases from 22 mg to 12 rag. In addition, the aluminum-doped PU coatings are of photocatalysis and self-cleaning functions.
