摘要： PROBLEM TO BE SOLVED: To obtain a resin tungsten high-density composite material which can maintain its shape, specific gravity and hardness properties, even under conditions of high temperature and high humidity.
SOLUTION: A coupling treatment for coating the surface of tungsten particles, with organic compounds of a silane or silicon base to prevent the tungsten particles from corroding easily, is given to them, before mixing them with thermoplastic resin in order to prevent them from oxidizing. Since the coupled tungsten particles will no longer be exposed directly to the atmosphere, oxidation does not progress, even under an environment of high temperature and humidity and they can maintain their shapes and surface roughness. Moreover, the resin tungsten composite material, obtained by mixing the coupled tungsten particles with the thermoplastic resin, is prone to deform at high temperature and high humidity. To prevent this, the surface of the thermoplastic resin is made to form a partially crosslinked structure so as to improve the heat resistance, by irradiating the surface of the resin-tungsten high-density composite material with an electron beam in order to prevent such a deformation.

摘要翻译：待解决的问题：即使在高温高湿的条件下，也可获得能够保持其形状，比重和硬度特性的树脂钨高密度复合材料。解决方案：在将它们与热塑性树脂混合之前，给予它们涂覆钨颗粒表面与硅烷或硅基底的有机化合物以防止钨颗粒易腐蚀的偶联处理，以防止它们从氧化。由于结合的钨颗粒将不再直接暴露于大气中，即使在高温和高湿度的环境下也不会发生氧化，并且它们可以保持其形状和表面粗糙度。此外，通过将结合的钨颗粒与热塑性树脂混合而获得的树脂钨复合材料在高温高湿下容易变形。为了防止这种情况，通过用电子束照射树脂钨高密度复合材料的表面，使热塑性树脂的表面形成部分交联的结构，从而提高耐热性，以防止这种形变。版权所有（C）2008，JPO＆INPIT
