た。Even when flame retarding a polyamide resin mixture containing a polyamide resin (hereinafter abbreviated as “MX nylon”) obtained from xylylenediamine and α, ω-linear aliphatic dibasic acid as a main component, an organic halogen It is already known that the flame-retardant effect is enhanced by adding a flame retardant and antimony trioxide. (JP-A-59-191759) However, a polyamide resin mixture containing MX nylon as a main component is melt-kneaded with antimony trioxide when producing a pelletized molding material, so that it is colored in gray and is thus flame-retardant. In the field where is required, there is a problem that it cannot be used for light-colored applications and parts that require coloring.

成物が得られることを発見し、上記目的を達成した。As a result of earnest studies, the present inventors have found that when a polyamide resin mixture containing MX nylon as a main component is blended with an organic halogen-based flame retardant and antimony trioxide to make it flame-retardant, an alkali metal of Group I of the periodic table of elements is used. Or, by adding a hydroxide of a Group II alkaline earth metal, it was discovered that a polyamide resin composition for molding excellent in flame retardance without coloring due to antimony trioxide was obtained, and the above object was achieved. .

極めて有効であるが、その配合割合が高くなると得られ
る製品の難燃性が低下する。HOOC (CH 2 ) n COOH (In the formula, n represents an integer of 4 to 18.) Among these dicarboxylic acids, MX nylon obtained by using adipic acid has various excellent performances as a molding material. It is particularly preferable because it gives a molded product. In the present invention, blending MX 66 with nylon 66 is
It is extremely effective in shortening the molding cycle time during molding and improving the molding workability, but if the blending ratio increases, the flame retardancy of the product obtained decreases.
従って、本発明において混合樹脂中に配合されるナイ
ロン66の量は、難燃性の付与、成形サイクル時間の短

ミド樹脂混合物中で１〜50重量％の範囲である。Therefore, the amount of nylon 66 blended in the mixed resin in the present invention is 1 to 50 in the polyamide resin mixture when flame retardancy is imparted, the molding cycle time is shortened, and the mechanical performance of the molded product is taken into consideration. It is in the range of% by weight.
