摘　　要：本文利用自行研发的一种强吸水性涂料制成厚度为0.05 mm的抑霜涂层,对涂层的持续亲水性和重复抑霜性能进行了测试。结果表明,该涂层经过20次的干湿循环之后仍然具有较强的吸水能力;在相对环境湿度为53%、壁温-10.5℃条件下的实验表明,该涂层的重复性抑霜效果良好。A new paint absorbing a large amount of water was developed for restraining frost formation. Hydrophilic surface was made using this paint with coating thickness about 0.05 mm. A series of experiments were carried out to test its durative hydrophilicity and cycling anti-frosting performance. Experimental results showed that the hydrophilic surface has strong water-absorption capacity. It shows good cycling anti-frosting performance under the condition of relative air humidity of 53% and cold plate temperature of -10.5℃.
