摘要： Provided is a flame-retardant thermoplastic resin composition in which any halogenated flame retardant is not used but a phosphoric flame retardant is used, which has flame retardancy meeting U.S. UL Standard 94 V-2, which exhibits excellent dripping performance during burning, and which is excellent in balance between properties. The flame-retardant thermoplastic resin composition contains 100 parts by mass of a copolymer mixture containing a graft copolymer (A) obtained by graft-polymerizing a rubbery polymer, a vinyl cyanide compound, and a copolymerizable vinyl compound and a vinyl copolymer (B) which is obtained by copolymerizing the vinyl cyanide compound and the copolymerizable vinyl compound and which has a mass-average molecular weight of 90,000 to 160,000 and 5 to 20 parts by mass of a phosphoric flame retardant (C) blended with the copolymer mixture. The content CB1 of vinyl cyanide units in the acetone-insoluble fraction of the copolymer mixture is 22.0% to 32.0% by mass, the content CB2 of vinyl cyanide units in the acetone-soluble fraction thereof is 22.0% to 34.0% by mass, and |CB1−CB2| is 0% to 3.0% by mass.
摘要翻译：本发明提供一种阻燃热塑性树脂组合物，其中不使用任何卤化阻燃剂，但使用磷阻燃剂，其阻燃性符合美国UL标准94V-2，其在燃烧时表现出优异的滴水性能，性能之间的平衡优异。阻燃性热塑性树脂组合物含有100质量份含有通过使橡胶状聚合物，乙烯基氰化合物和可共聚乙烯基化合物接枝聚合得到的接枝共聚物（A）和乙烯基共聚物（B）的共聚物混合物，通过共聚合乙烯基氰化合物和可共聚的乙烯基化合物，其质均分子量为90,000至160,000，和5至20质量份与共聚物混合物共混的磷阻燃剂（C）。共聚物混合物的丙酮不溶级分中的乙烯基氰单元的含量CB1为22.0〜32.0质量％，丙酮可溶成分中的乙烯基氰单元的含量CB2为22.0〜34.0质量％， | CB1-CB2 | 为0〜3.0质量％。

摘要： An oil seal ring is obtained which can maintain its oil scraping performance at a satisfactory level despite the frictional wear it undergoes. It is formed with a tapered sliding surface having a hardness maximized at its oil scraping edge and decreasing with the distance therefrom. It can be manufactured by casehardening a ring blank through one end surface thereof which is oppositely tapered and subsequently finishing the end surface to shape.
