以苯乙烯和丙烯酸丁酯为主要单体，采用半连续乳液聚合法合成了4种聚合物胶乳，即以苯乙烯和丙烯酸丁酯为主要单体合成的基础胶乳、以乙烯基三乙氧基硅烷为主要单体合成的胶乳Si、以甲基丙烯酸十二氯庚酯为主要单体合成的胶乳F和以八甲基环四硅氧烷（D4）为主要单体合成的胶乳D4。乳胶膜的表征表明，乳胶D4和基础乳胶膜的吸水率低于乳胶F和Si的吸水率;而它们与水的接触角也小于其他两种乳胶膜的吸水率。将该乳液作为涂层应用于不同形式的钢和铝金属上，以评价其在腐蚀和防冰试验中的性能。涂布于钢板上进行耐水性测试，发现D4胶乳和基础胶乳的耐水性较差，而F胶乳和Si胶乳的涂膜耐水性较好。在防冰试验中，无论是在铝螺旋线圈上喷涂涂层，然后喷水冷却，还是在铝绞线上喷涂涂层，然后在冰风洞中进行防冰试验，D4乳胶的防冰性能最好，基础乳胶的防冰性能最差，F乳胶和Si乳胶的防冰性能介于两者之间。并将其涂敷在钢芯铝绞线用不锈钢棒上进行了耐高温试验。其防冰效果与铝卷或绞线的防冰效果相似，D4乳胶防冰效果最好，基础乳胶防冰效果最差，但不同试验中其防冰效果的差异程度不同。
Four polymer latexes, including Base latex synthesized using styrene and butyl acrylate as the main monomers, Latex Si prepared with 4.0 wt% of vinyl triethoxysilane, Latex F with 4.0 wt% of dodecafluoroheptyl methacrylate and Latex D4with 8.5 wt% of octamethyl cyclotetrasiloxane (D4), were prepared through a semi-continuous emulsion polymerization. Characterization of the latex films revealed that water absorption of the films of Latex D4and the Base latex were lower than those of Latexes F and Si; whereas their contact angle with water were also smaller than those of the other two latex films. The latexes were applied as coating onto steel and Al metals of different forms to evaluate their performance in corrosion and anti-icing tests. Coated on steel plates for water resistance test, it was found that Latex D4and Base latex showed poorer performance; whereas the films made from Latex F and Latex Si showed better performance. In anti-icing tests, with the coating applied either on Al circular helix coils followed by refrigeration after water spray, or on Al stranded power line followed by anti-icing test in an IWT (ice wind tunnel), Latex D4showed the best anti-icing performance, Base latex with the lowest performance, and the other two, Latex F and Latex Si, located in between. The test in IWT was also conducted with the latexes coated on stainless steel rods used in Al stranded power line with reinforced steel core. The anti-icing effectiveness was quite similar to those observed on Al coils or stranded power transmission lines: Latex D4showed the highest performance and Base latex the lowest, although the differences of the magnitude in their performance were obviously different in different tests.
