新型耐蚀涂料—氟橡胶涂料的研究

The Development of A New Type of Corrosion Resistant Coating --Fluor or ubber Coating

氟橡胶涂料是以氟橡胶为基料的涂料。其涂层具有氟橡胶的特性,即优异的耐高温,耐油及耐多种化学药品的浸蚀。由偏氟乙烯、四氟乙烯和六氟丙烯三元共聚的氟碳聚合物比二元共聚物具有更高的耐热性和抗腐蚀能力。采用胺类固化剂和适当偶联剂可加快固化速度,降低固化温度,提高涂层附着力。漆膜可在室温固化,使用极其方便,因此用途日益广泛。含有MgO吸酸剂的涂层可在200℃下长期工作。含有PbO吸酸剂的涂层可耐强酸,强碱。橡胶涂层由于基料分子量大,施工不同于一般油漆,对表面处理亦更严格。

The fluororubber coating based on fluororubber is characterized by excellent resistance to heat, oil and chemicals. This coating consists of fluorocarbon polymer, amine curing agent, couplant, acid absorber and solvents. The film can be cured at room temperature and used easily and widely.
