摘要
【目的】通过添加改性后的无机填料,提高涂层的耐磨性,为长效防冰提供有效的解决方案。【方法】以氟碳树脂为成膜物质,石英粉和二氧化硅结合低表面能长链有机硅作为功能填料,制备了一种具有延迟结冰效果的高耐久型疏水涂料。重点考察了涂层的疏水性、抗机械损伤性、耐人工老化性以及抗结冰性。【结果】研制的涂料水接触角达到120°,属于非润湿性材料,拉开法附着力达到7 MPa,砂轮磨耗3000 r后质量损失<0.05 g,人工老化达3000 h后保光率超80%;此外,在低温环境下具有明显的延迟结冰和降低着冰力的作用。【结论】自制的有机硅防覆冰涂料兼具防冰性和高耐磨性,有望为低温环境下风电设施、铁路交通以及电力传输等领域的结冰问题提供重要解决方案。
[Objective]By adding modified inorganic fillers,the abrasion resistance of the coating is improved,providing effective solutions for long-lasting anti-icing.[Methods]A highly durable hydrophobic coating with delayed icing effect was prepared,with fluorocarbon resin as the film-forming material and quartz powder and silica combined with low surface energy long-chain organosilicon as the functional fillers.The study focused on the coating′s hydrophobicity,resistance to mechanical damage,artificial weathering test and anti-icing performance.[Results]The results showed that the developed coating had water contact angle of 120°,classifying it as a non-wetting hydrophobic material.The pull-off adhesion reached 7 MPa,and after abraded 3000 r by abrasive wheels,the mass loss was less than 0.05 g.After 3000 h of artificial weathering test the gloss retention exceeded 80%.Additionally,water droplets at low-temperature environments revealed a significant delay in ice formation and reducing ice adhesion on the coating.[Conclusion]Homemade organic silicon antiicing coatings have anti-icing performance and high abrasion resistance,and are expected to provide an important solution to icing problems in wind power facilities,railway transportation,and power transmission in low-temperature environments.
