    Abstract: A material for a gasket, wherein a chromate or non-chromate film, a phenol resin primer layer and a polyol-crosslinkable fluororubber layer are formed on one or both surfaces of a steel plate in this sequence from the side of the steel plate; the polyol-crosslinkable fluororubber layer is a rubber layer obtained by applying a fluororubber composition that comprises fluororubber, a polyol-based cross-linking agent, an amine-based cross-linking accelerator and silica to the phenol resin primer layer, followed by heating; and the amine-based cross-linking accelerator is a tertiary amine or a salt of a tertiary amine obtained by a reaction between a tertiary amine and an acid. Provided is a material for a gasket mounted in an engine of a vehicle that, in the actual use environment, does not suffer rubber peeling in a part where it contacts water or an anti-freezing solution even if the gasket is used in a state where it contacts different types of metals and, in a sealing part around a combustion room, abrasion or ply separation of a rubber layer hardly occurs.

    Abstract translation: 在钢板的一面或两面,从钢板的侧面开始形成有用于垫片的材料,其中铬酸盐或非铬酸盐膜,酚醛树脂底漆层和多元醇交联氟橡胶层按顺序形成在钢板的一个或两个表面上; 多元醇交联性氟橡胶层是通过将含氟橡胶,多元醇系交联剂,胺类交联促进剂和二氧化硅的氟橡胶组合物涂布在酚醛树脂底漆层上,然后加热而得到的橡胶层。 胺类交联促进剂是通过叔胺与酸反应得到的叔胺或叔胺盐。 本发明提供一种安装在车辆发动机中的垫圈的材料,其在实际使用环境中,即使在使用了垫圈的状态下也不会与水接触的部位或防冻液部分遭受橡胶剥离, 它接触不同类型的金属,并且在燃烧室周围的密封部分中几乎不发生橡胶层的磨损或层压分离。
