Abstract
【解決手段】安定化のために、低粘度と高粘度のポリビニルアルコールからの混合物を含有する分散粉末を提供する。
【選択図】なし
Description
a)高くても3mPasのヘップラによる粘度μ1を有する少なくとも1種のポリビニルアルコールと
b)4mPas〜25mPasのヘップラによる粘度μ2を有する少なくとも1種のポリビニルアルコールと
を含有し、かつ該保護コロイドのヘップラによる重み付き粘度(gewichtete Viskositaet)μwが、高くても6mPasであることを特徴とする分散粉末である。
μw=μ1*x1+μ2*x2+……μi*xi (1)
[式中、
iは、使用されるポリビニルアルコールa)とb)の数、従って少なくとも2を意味し、
xiは、ヘップラによる粘度μiを有するそれぞれのポリビニルアルコールiの質量分率である]によって記載することができ、かつ一般方程式(2)
xi=wi/(w1+w2+…wi) (2)
[式中、
wは、ポリビニルアルコールのそれぞれの質量を意味し、かつ
iは、前記の意味を有する]によって記載することができる。
1/Tg=x1/Tg1+x2/Tg2+…+xn/Tgn
[式中、
xnは、モノマーnの質量分率(質量%/100)を表し、かつ
Tgnは、モノマーnの単独重合体のケルビンでのガラス転移温度である]

試験:
得られた粉末を、その粉末特性と封止スラリー中での加工とスチロポール(Styropor)への付着とについて調査した。
耐ブロッキング性の測定のために、分散粉末をねじ込み口金を有する鉄管中に充填し、次いで金属製ポンチで負荷をかけた。負荷をかけた後に、乾燥棚において50℃で16時間貯蔵した。室温に冷却した後に、該粉末を管から取り出し、耐ブロッキング性を定性的に粉末の圧壊によって測定した。耐ブロッキング性は、以下のとおり階級付けした:
1〜3 = 非常に良好な耐ブロッキング性
4〜6 = 良好な耐ブロッキング性
7〜8 = 十分な耐ブロッキング性
9〜10 = 耐ブロッキング性なし;粉末は圧壊後にはもはや易流動性でない。
再分散液の沈降挙動を、粉末の再分散可能性の尺度として用いる。再分散液は、高剪断力の作用によって水中50%で作製した。
スチロポールに対する剥離強さ(%剥がれ(ausriss))を以下の配合で試験した(3%重合体割合):
珪砂 665部
ポルトランドセメント 300部
セルロース 5部
再分散粉末 30部
剥離強さを以下の貯蔵条件後に測定した:
7T/21N: 7日間乾燥/21日間湿潤(湿式貯蔵)
セメント含有封止スラリーの加工(VA)の測定は、以下の配合で定性的に行う:
珪砂 547部
ポルトランドセメント 150部
セルロース 3部
再分散粉末 300部
再分散粉末の耐ブロッキング性、沈降挙動、剥離強さ及び加工の試験結果を第1表にまとめる。
第1表のデータから、粉末特性は、本発明による生成物P1及びP2の場合に悪影響がおよぼされず、利用側のデータが改善されることを確認することができる。
