〔熱安定性〕
押出しで得られたポリアセタール樹脂組成物(3±0.01g)を、窒素雰囲気下(50nl/hr)で、230℃に加熱、溶融させ、滞留時間2〜30分間に発生するホルムガスを、1mol/lの亜硫酸ナトリウム水溶液に吸収させ、生成する水酸化ナトリウムを、1/100規定の硫酸で滴定し、ホルムガス量に換算して求めた。
この滴定には、指示薬としてチモールフタレインを用い、青色が無色となった時点を終点とした。
(Thermal stability)
The polyacetal resin composition (3 ± 0.01 g) obtained by extrusion was heated and melted at 230 ° C. under a nitrogen atmosphere (50 nl / hr), and the form gas generated during a residence time of 2 to 30 minutes was reduced to 1 mol / mol. 1 of sodium sulfite aqueous solution, and the resulting sodium hydroxide was titrated with 1 / 100N sulfuric acid and converted to the amount of form gas.
In this titration, thymolphthalein was used as an indicator, and the time when the blue color became colorless was determined as the end point.
〔押出し性〕
押出しで得られたポリアセタール樹脂組成物のペレット2.5kgを、目視で確認し、ペレットが繋がった形の物を連粒と称し、その連流物を取出し重量を測定した。
その割合を計算し点数付けを行った。点数が大きければ大きいほど押し出し性が良い(連粒の割合が多いほど押出し性が良くない)ことを示す。
3:連粒なし
2:連粒の割合が10%未満
1:連粒の割合が50%以上
[Extrusion property]
2.5 kg of pellets of the polyacetal resin composition obtained by the extrusion were visually confirmed, and the connected pellets were referred to as continuous grains, and the connected products were taken out and the weight was measured.
The ratio was calculated and scored. The larger the score, the better the extrudability (the larger the ratio of continuous grains, the poorer the extrudability).
3: No consecutive grains 2: The proportion of consecutive grains is less than 10% 1: The proportion of consecutive grains is 50% or more
〔異物〕
ポリアセタール樹脂組成物を、220℃に設定したホットプレス(松田製作所製)で、型枠として180mm×180mm×2mm(厚み)を用いて、平板をプレス成形した。
成形板の両面について、ルーペを用いて0.1mm以上の異物の数を測定した。
異物は、黒、茶、赤、黄等の色があるが全てを数えた。
(Foreign matter)
Using a hot press (manufactured by Matsuda Seisakusho) set at 220 ° C., the polyacetal resin composition was used to press-mold a flat plate using a 180 mm × 180 mm × 2 mm (thickness) mold.
The number of foreign substances having a size of 0.1 mm or more was measured on both surfaces of the molded plate using a loupe.
The foreign substances were black, brown, red, yellow and other colors, but all were counted.
〔金属粉末の分散性〕
設定170℃に加温したラボプラストミルを用いて、20μmのSUS316L粉末70gと、下記の実施例・比較例で得られたポリアセタール樹脂組成物30gとを半溶融状態で30分混練し、おこし状の固形物(体積36cm3)を作製した。得られた固形物から、任意に選択した部分5か所を10gずつ切出した。
次に、設定550℃の電気炉中でポリアセタール樹脂組成物を脱脂させ、残った金属の重量を測定した。そして最大重量と最少重量の比を求めた。この比が小さいものほど分散性が良いことを示す。
(Dispersibility of metal powder)
Using a Labo Plastomill heated to a setting of 170 ° C., 70 g of SUS316L powder of 20 μm and 30 g of a polyacetal resin composition obtained in the following Examples and Comparative Examples were kneaded in a semi-molten state for 30 minutes, and the resulting mixture was kneaded. (Solid volume: 36 cm 3 ) was prepared. Five arbitrarily selected portions were cut out at 10 g each from the obtained solid material.
Next, the polyacetal resin composition was degreased in an electric furnace set at 550 ° C., and the weight of the remaining metal was measured. Then, the ratio between the maximum weight and the minimum weight was determined. The smaller the ratio, the better the dispersibility.
