摘要: 通过对铝合金及聚甲基丙烯酸甲酯(PMMA)基底涂覆不同弹性涂层进行表面改性,研究了涂层弹性对基底结冰附着强度的作用。用单组份室温硫化硅橡胶WH-705与BOPP进行对比。采用水杯制冰结冰强度测试试验法,以结冰切向附着力为指标,测量铝合金和PMMA两种材料(典型金属和非金属材料)基底表面未涂覆和涂覆弹性涂层后的结冰附着强度。试验结果表明,相对于标准基底,涂覆弹性涂层后基底表面结冰强度有显著变化。其中,涂覆硫化硅橡胶的铝表面结冰强度降低73.27%,PMMA表面降低14.85%。分析表明,涂层的弹性系数、分布规律等对结冰附着强度的影响显著。本文研究可为弹性涂层在防除冰方面的实际应用提供依据。
