実施例１
(1) 予備混合
熱可塑性樹脂としてポリプロピレン（商品名：出光ポリプロＪ−４００Ｍ：４５重量％，Ｈ−７００：５５重量％：出光石油化学（株）製）７５重量部、アミノトリアジン化合物硫酸塩として粒径２０μｍ，水分含量0.１重量％のメラミン硫酸塩(II)２５重量部からなる組成物１００重量部に対して0.２重量部のトリス（２，４−ジ−ｔ−ブチルフェニル）ホスファイト（商品名：ＭＡＲＫ２１１２：旭電化工業（株）製）、0.１重量部のペンタエリスリチル−テトラキス〔３−（３，５−ジ−ｔ−ブチル−ヒドロキシフェニル）プロピオネート〕（商品名：ＩＲＧＡＮＯＸ１０１０：チバガイギー社製）、0.３重量部のステアリン酸カルシウム（大日本インキ化学工業（株）製）を配合し、ヘンシェルミキサーで予備混合した。
(2) 溶融混練
得られた予備混合物を、二軸混練機（商品名：ＰＣＭ４５ＩＩ：池貝鉄鋼（株）製）を用いて、下記の条件で溶融混練して組成物を製造し、さらにストランドカットを用いて連続的にペレット化した。
・混練温度 ２４０℃〜２５０℃
・スクリュー 回転数２５０ｒｐｍ
・メッシュ ６０と８０の組み合わせ
・ベント １つ（真空）
・吐出量 ５０〜６０ｋｇ／ｈ
溶融混練中、メラミン硫酸塩は分散良好で、連続的に造粒してもメッシュ詰まりせずベントアップもしないで、生産性は良好であった。さらに得られた難燃性樹脂組成物のペレットを、日精樹脂工業（株）製の射出成形機（商品名ＦＥ−１２０、ＰＳ−４０）を用いてシリンダー温度１９０〜２１０℃、金型温度５０℃で射出成形して試験片を作製し、その特性を下記の評価方法で評価した。その結果、メラミン硫酸塩の分散性は良好で、最大断面積が0.０５ｍｍ2 以上の白色凝集物は縦１０ｃｍ，横１０ｃｍ，厚さ0.５ｍｍのシート中には認められなかった。又、アイゾット衝撃強度は４３ｋＪ／ｍ、ＵＬ９４難燃性はいずれもＶ−２であり、ΔＥ（色差；光照射前後の色調の相違）は0.５８、ΔＹＩ（黄色度差；光照射前後の黄色度の相違）は−0.５８であり耐衝撃性、難燃性および耐光性に優れており、得られた難燃性樹脂は白色で、全ての色に調色可能であり、臭いもなかった。
Example 1
(1) Polypropylene as a premixed thermoplastic resin (trade name: Idemitsu Polypro J-400M: 45% by weight, H-700: 55% by weight: manufactured by Idemitsu Petrochemical Co., Ltd.) 75 parts by weight, as an aminotriazine compound sulfate 0.2 parts by weight of tris (2,4-di-t-butylphenyl) with respect to 100 parts by weight of a composition consisting of 25 parts by weight of melamine sulfate (II) having a particle size of 20 μm and a water content of 0.1% by weight. Phosphite (trade name: MARK2112: manufactured by Asahi Denka Kogyo Co., Ltd.), 0.1 part by weight of pentaerythrityl-tetrakis [3- (3,5-di-t-butyl-hydroxyphenyl) propionate] (trade name) : IRGANOX1010: manufactured by Ciba Geigy Co., Ltd.) and 0.3 parts by weight of calcium stearate (manufactured by Dainippon Ink and Chemicals Co., Ltd.) were blended and premixed with a Henschel mixer.
(2) Melt-kneading The obtained premix is melt-kneaded using a twin-screw kneader (trade name: PCM45II: manufactured by Ikegai Steel Co., Ltd.) under the following conditions to produce a composition, and further strand-cut. Was continuously pelletized using.
・ Kneading temperature 240 ℃ ～ 250 ℃
・ Screw rotation speed 250 rpm
・ Combination of mesh 60 and 80 ・ One vent (vacuum)
・ Discharge rate 50-60 kg / h
During the melt-kneading, the melamine sulfate was well dispersed, and even if it was continuously granulated, the mesh did not clog and vent-up did not occur, and the productivity was good. Further, the pellets of the flame-retardant resin composition obtained were subjected to a cylinder temperature of 190 to 210 ° C. and a mold temperature of 50 using an injection molding machine (trade name: FE-120, PS-40) manufactured by Nissei Resin Industry Co., Ltd. A test piece was prepared by injection molding at ° C., and its characteristics were evaluated by the following evaluation method. As a result, the dispersibility of the melamine sulfate was good, and no white agglutinate having a maximum cross-sectional area of 0.05 mm2 or more was observed in the sheet having a length of 10 cm, a width of 10 cm, and a thickness of 0.5 mm. The impact intensity of Izot is 43 kJ / m, the flame retardancy of UL94 is V-2, ΔE (color difference; difference in color tone before and after light irradiation) is 0.58, and ΔYI (difference in yellowness; before and after light irradiation). The difference in yellowness) is -0.58, which is excellent in impact resistance, flame retardancy, and light resistance. The obtained flame retardant resin is white, can be toned in all colors, and has an odor. There wasn't.
