摘　　要：针对驻岛礁高温设备面临高温与海洋环境侵蚀极易造成腐蚀破坏的问题,研制耐高温重防腐防护涂料。以胺基POSS改性有机硅树脂为成膜树脂,利用胺基POSS的八臂活性结构提高树脂的交联密度,增加漆膜的致密性,抑制腐蚀性介质向漆膜内部的侵蚀;再配合合适的玻璃粉填料、耐高温填料、防腐填料制备具有优异防护效果的耐高温重防腐涂料。所制备耐高温重防腐涂料能在500℃环境下长效使用,且耐热前后均能展现出1200h以上的耐中性盐雾性能,可解决驻岛礁高温设备或海上高温设备的腐蚀问题。In response to the problem that high-temperature equipment stationed on islands is prone to corrosion damage caused by high temperature and marine environmental erosion,a high-temperature resistant and heavy-duty anti-corrosion protective coating is developed.Using amino based POSS modified silicone resin as a film-forming resin,the eight arm active structure of amino based POSS is utilized to increase the crosslinking density of the resin,increase the density of the paint film,and inhibit the corrosion of corrosive media into the interior of the paint film.The high-temperature and heavy-corrosion resistant coating with good protective effects is prepared by combining appropriate glass powder fillers,high-temperature resistant fillers,and anti-corrosion fillers.The prepared coating can be used for a long time in an environment of 500℃,and exhibits neutral salt spray resistance for more than 1200 hours before and after heat resistance.Hence,this coating can solve the corrosion problem of high-temperature equipment stationed on islands or offshore.
