This invention provides an insulating protective material effective for protection of electronic and electric devices such as electronics elements. This insulating protective material contains at least one hydrous oxide of a metal which has ion exchange properties together with a fusion bonding component such as low-melting glass, epoxy resin, phenolic resin, silicone resin, etc. and a filler such as fused silica, .beta.-eucryptite, glass fiber, glass beads, etc. Said specific hydrous oxide can be used together with a sulfur-containing organic high molecular weight compound. The hydrous oxides used in protective materials as a sealing material for electronic and electric devices can capture an ionic impurity eluted from the components of the protective material and fix it therein thereby to provide stable electronic materials excellent in performance.
本发明提供了一种绝缘保护材料,可有效保护电子和电气设备(如电子元件)。该绝缘保护材料含有至少一种具有离子交换性质的金属水合氧化物,以及熔合粘结成分,如低熔玻璃、环氧树脂、酚醛树脂、硅树脂等,以及填料,如熔融二氧化硅、β-欧克瑞普蒂特、玻璃纤维、玻璃珠等。所述特定的水合氧化物可以与含硫有机高分子化合物一起使用。用于电子和电气设备的保护材料中使用的水合氧化物可以捕获从保护材料组分中析出的离子杂质,并将其固定在其中,从而提供性能优异的稳定电子材料。
