低表面能缓释型除冰涂层抗凝冻效果评价
|
摘要
采用A、B、C等3种组分配置了低表面能缓释型除冰涂层材料,分别采用冷冻试验、敲击和落球冲击试验对该除冰涂层的抗凝冰效果进行了评价,采用负荷轮碾压试验评价了除冰涂层耐久性;分别将涂有低表面能缓释型除冰涂层、工业除冰盐和未做处理的马歇尔、小梁及湿轮磨耗试件置于室外凝冻天气条件下,对比3种试件表面凝冰情况,对该涂层材料的除冰雪效果进行了分析;铺筑了除冰涂层试验路,并对试验路进行了渗水性能和抗滑性能检测,对低表面能缓释型除冰涂层对路面表面性能的影响进行了分析。结果表明:所配置的凝冰涂层材料具有较好的抗凝冰和除雪效果,基本不影响原路面的表面性能。
The low surface energy slow-release deicing coating material is prepared by A,B and C three kinds of component,and its icing-resistance effect is evaluated by freezing test,percussion test and falling ball impact test,and the durability of its coating is assessed by load wheel rolling test.Testspecimens which are respectively coated with low surface energy slow-release deicing coating,industrial deicing salt,and untreated Marshall specimens,trabecular and wet abrasion wheel specimens and agitation are placed in outdoor freezing weather conditions to compare and analyze the de-icing effect of the above specimens.Further a test road section is paved which is coated with low surface energy slow-release deicing coating material,and tests are conducted to monitor its anti-permeability and anti-sliding performance,and the impact of low surface energy slow-release de-icing coating material on the performance of the road surface is analyzed.Results show that the prepared coating material has a good anticoagulant and deicing effect on the road surface which hardly affect the performance of the original road surface.
