<p>PROBLEM TO BE SOLVED: To obtain a frame-retardant resin material that is excellent in resis tance to environmental pollution and useful for an electron beam regulator by using a non-halogen resin composition, a metal oxide hydrate and antimony trioxide. SOLUTION: This resin material contains (A) 100 pts.wt. of a non-halogen resin composition, for example, for polyamide resin, (B) a metal hydroxide such as aluminum hydroxide or magnesium hydroxide, preferably in an amount of 5-40 pts.wt., and (C) antimony trioxide, preferably in an amount of 20-40 pts.wt. and zinc borate, preferably in an amount of 0-20 pts.wt. A magnetic material, for example, a powder of ferrite magnet or alnico magnet powder is formulated to this flame-retardant resin composition to prepare a flame- retardant resin magnetic material.</p> |
