摘要:

通过乙醇分别对聚脲树脂(PU)和十六烷基三甲氧基硅烷(HDTMS)进行稀释，在混凝土表面构建3%~100%范围内14种浓度的PU涂层和1%~30%范围内8种浓度的HDTMS涂层，对比研究了不同涂层的接触角，并根据两种试剂的最佳浓度制备了PU-HDTMS涂层。在环境温度为-20 ℃的低温条件下，通过结冰时间、不同倾斜角度下涂层的积冰量以及冰-涂层粘结强度综合评价涂层的抗结冰性能；根据多次结冰-除冰循环，测定涂层的抗结冰耐久性。结果表明：PU涂层和HDTMS涂层的最佳浓度分别为7%和5%；100%浓度的PU涂层表面光滑，冰粘结强度较低但延缓结冰时间效果不显著，稀释后抗结冰性能下降；对于HDTMS涂层，5%浓度能有效延缓结冰时间且冰粘结强度较低。PU-HDTMS涂层的接触角为153.38°，具有更好的抗结冰性能和抗结冰耐久性。

Abstract：

As raw materials, polyurea resin (PU) and hexadecyltrimethoxysilane (HDTMS) were diluted with ethanol, then PU paints with concentrations of 3% to 100%, and HDTMS paints with concentrations of 1% to 30% were prepared respectively, of which the contact angles for water were comparatively examined. Meanwhile, a composite paint of PU-HDTMS based on the optimal concentrations of the above two paints was prepared. Further, coatings of PU, HDTMS and PU-HDTMS were applied on mortar blocks respectively. The anti-icing performance of the coatings was comprehensively evaluated by measuring the static freezing time on the coatings, the amount of ice accumulation on the coatings at various tilt angles, and the bond strength between the formed ice and the coatings at -20 ℃. The anti-icing durability of the coatings was assessed through multiple icing-deicing circles. The results indicated that the optimal concentrations for PU and HDTMS coatings were 7% and 5%, respectively. The surface of the 100%PU coating was smooth and exhibited low ice bond strength; however, its effectiveness in delaying freezing time was not significant, and the icing resistance of PU coatings decreased upon dilution. In contrast, the 5%HDTMS coating effectively delayed the freezing time while also demonstrating low ice bond strength. The contact angle of the PU-HDTMS coating was measured as 153.38°, which was superior to that of both the PU and HDTMS coatings.

Key words： polyurea resin silane contact angle anti-icing performance anti-icing durability
