摘要：

针对超疏水涂层膜在固化过程中功能性颗粒的不受控运动以及传统的热固化能耗高、耗时长的缺点,通过对羰基铁粉进行改性,并将磁控技术和蓝光固化技术相结合构筑超疏水薄膜。分析改性剂质量比、用量、pH值以及温度对羰基铁粉改性效果的影响,确定最佳改性工艺;研究了磁场强度对光固化薄膜表面接触角以及形貌的影响规律。结果表明:当改性剂3-(甲基丙烯酰氧)丙基三甲氧基硅烷与1H,1H,2H,2H-全氟葵基三甲氧基硅烷质量比为1:3,质量分数为20%,pH值为6,温度为75 ℃,时间为1.5 h时,羰基铁粉表面改性效果最佳,其活化度达到96%,Zeta电位绝对值由22 mV提高至43 mV;随着磁感应强度的增加,薄膜表面接触角不断增加,当磁感应强度为75 mT时,超疏水薄膜的表面接触角达到157.6°,滚动角为6°,符合超疏水标准。

Abstract:

In view of the uncontrollable movement of functional particles in the curing process of superhydrophobic coating film, high energy consumption and long time consuming in traditional thermal curing process, the superhydrophobic film was prepared by modifying carbonyl iron powder and combining magnetic control technology and blue light curing technology. The optimal modification process was determined by analyzing the effects of modifier ratio, dosage, modified pH value and temperature on the modification effect of carbonyl iron powder, before the effects of magnetic field intensity on the surface contact angle and morphology of UV curable films were studied. The results show that when the mass ratio of modifier 3-(methacryloyloxy) propyl trimethoxysilane to 1H, 1H, 2H, 2H-perfluoro sunnyl trimethoxysilane is 1:3, the mass fraction is 20%, the modified pH value is 6, the modified temperature is 75 ℃ and the modified time is 1.5 h, the surface modification effect of carbonyl iron powder is the best with activity reaching 96% and the absolute value of zeta potential increasing from 22 mV to 43 mV. With the increase of magnetic field intensity, the surface contact angle of the film increases continuously. When the magnetic field intensity is set to 75 mT, the surface contact angle of the superhydrophobic film reaches 157.6° and the rolling angle is 6°, which meets the superhydrophobic standard.
