Abstract
Description
(a)ポリオキシメチレン約20〜約80重量パーセント、
(b)酸化亜鉛、二酸化チタン、および硫酸バリウムからなる群から選択される、少なくとも1つの被覆鉱物約20〜約80重量パーセント、ならびに
(c)少なくとも1つの熱安定剤約0.05〜約4重量パーセント
を含み、
重量百分率が、組成物の全重量を基準にしたものである組成物が提供される。
組成物のペレットを259℃の温度において約30分間加熱することによって、組成物の熱安定性を決定した。亜硫酸ナトリウム溶液を含む滴定容器に、加熱ステップ中放出されたホルムアルデヒドが窒素流で流し込まれ、亜硫酸ナトリウムと反応して、水酸化ナトリウムが生成する。生成した水酸化ナトリウムを塩酸で連続滴定して、本来のpHを維持する。使用された酸の全量を時間の関数としてプロットする。30分で消費された酸の全量は、ポリオキシメチレンを加熱することによって生成したホルムアルデヒドに比例し、熱安定性の定量的尺度である。熱安定性(パーセント)(TEF−Tと呼ばれる)を、次式で算出する:
TEF−T(%) = (V30×N×3.003)/S
式中、
V30 = 30分で消費された酸の全量(mL)、
N = 酸の規定度、
3.003 = (30.03(ホルムアルデヒドの分子量)×100%)/(1000mg/g)、および
S = 試料重量(グラム)。
表1に、結果を「TEF−T」という項目名で示す。
30インチのワーナー&フライダー(Werner & Pfleiderer)ZSK−30二軸押出機を使用して、表1および2に示す材料をコンパウンドした。ブレンドを、バレル温度約190〜210℃、スクリュー速度約150RPM、および速度約30ポンド/時でコンパウンドした。押出機を出ると、組成物を冷却し、ペレット化した。
