【摘要】 我国航空母舰的成功首航，将带动海洋工程的迅猛发展；其巨大甲板表层的防滑涂料，也成了人们关注的焦点。传统的环氧树脂防滑涂料，长期暴露在恶劣的海洋环境中，耐用程度下降，需要耗巨资进行维修和更换；且涂料降解老化后，产生的低分子化合物，排放到海洋大气中，加剧了生态污染。有机硅树脂，以其Si-O-Si键和有机基团的特殊分布，具备较好的耐水耐热及耐候性能；因此，国内外学者广泛开展了有机硅防滑涂料的研究。本课题以有机硅树脂为成膜物质、KH560为固化剂，二氧化钛(TiO2)和氧化锌(ZnO)为着色颜料、滑石粉(TALC)和氧化铝(Al2O3)为功能填料，制备出双组分有机硅防滑涂料；通过正交试验，研究了影响涂料硬度、抗冲击性、附着力、耐磨性的主次因素，探讨了涂膜的耐海水性、耐十二烷基苯磺酸钠(SDBS)性、耐紫外老化性、耐盐雾性和耐热性。研究得出有机硅防滑涂料的最佳配比：硅树脂、二氧化钛、氧化锌、滑石粉、氧化铝、固化剂分别占涂料总量的33%、24%、8.5%、20%、15%、6%，其他适量。同时，采用环氧树脂对有机硅树脂进行改性，制备出改性硅树脂后，以其为成膜物质，通过单因素控制法进行复合试验，探究固化剂、颜料和功能填料的加入量，进行干燥时间、固含量、附着力、耐磨性等测试，得到双组分改性树脂防滑涂料的最佳配比：改性树脂、二氧化钛、滑石粉、氧化锌、固化剂分别占涂料总量的30%、16.5%、11.6%、19.8%、16.5%、13%，其他适量。利用最佳配比分别制备出有机硅防滑涂料和改性硅防滑涂料，对比分析其性能差异；采用超景深三维视频显微镜、SEM以及能谱仪对其摩擦磨损形貌进行表征，研究其防滑机理。研究发现：与硅树脂相比，树脂改性后制备的涂膜，防滑性和耐磨性均得到显著改善，防滑涂料的防滑性与耐磨性均随无机填料的增多有一定程度的提高，涂料摩擦时磨粒磨损、粘着磨损共存。更多还原

【Abstract】 The success of the maiden voyage for aircraft carriers in our country, drive the rapid development of the Marine industry; Anti-slip coating on the surface of its huge deck, also become the focus of attention. Traditional anti-slip coating made of epoxy resin, the longer it exposure to the harsh Marine environment, the shorter it will be used, which needs huge sums for repair and replacement; the low molecular compound is produced by the its degradation ageing, which exacerbate the ecological pollution. Organic silicon resin with its special distribution of Si-O-Si and organic group has excellent heat resistance, weatherability, water resistance; Therefore, organic silicon non-slip coating have been researched as a popular topic by domestic and overseas scholars.This project uses silicone as film-forming substance, KH560as curing agent, TiO2and ZnO as pigments, TALC and Al2O3as functional filler, two-component silicone non-skid coating is prepared. Through orthogonal test, the primary and secondary factors of hardness, impact resistance, adhesion, and wear resistance is investigated; the seawater resistance, SDBS resistance, ultraviolet aging resistance, salt fog resistance and heat resistance is discussed. The results show the best proportion of organic silicon anti-slip coating is followed:the amounts of silicon resin, TiO2, ZnO, TALC, Al2O3, curing agent are33%,14%,8.5%,20%,15%,6%, respectively.In the same way, silicone is modified by silicone and epoxy resin. Using modified silicone resin as the film-forming material, through single factor tests to explore the amount of curing agent, pigments and functional filler. The results show the best proportion of modified silicon anti-slip coating is followed:the amounts of modified silicon resin, TiO2, ZnO, TALC, Al2O3, curing agent are30%,16.5%,11.6%,19.8%,16.5%,13%, respectively.According to the above results, silicone non-skid coating and modified silicone non-skid coating of optimal proportion are prepared, performance differences are analyzed by comparison test; the non-skid mechanism is researched by the study on coating microstructure, such as three-dimension microscope(3-DVM)、scanning electrical microscopy(SEM) and Energy Disperse Spectroscopy (EDS). Study shows that compared with silicone, the skid resistance of modified resin coating is improved, it increase to some extent, the same as abrasion resistance. Abrasive wear coexists with adhesive wear in friction progress.更多还原
