Description
非特許文献1では、適切な塩濃度の水溶液中で正電荷をもつポリカチオンと負電荷をもつポリアニオンと溶解させたポリイオンコンプレックスを土壌に散布する方法が開示されているが、固定化強度で必ずしも満足する結果が得られているわけではなく、ポリイオンコンプレックス溶液を調製するのに時間を要し作業効率が低下するといった課題がある。
一般式(1)
R1は水素又はメチル基、R2、R3は炭素数1〜3のアルキルあるいはヒドロキシアルキル基、R4は水素、炭素数1〜3のアルキル基、炭素数7〜20のアルキル基あるいはアリール基であり、同種でも異種でも良い、Aは酸素またはNH、Bは炭素数2〜4のアルキレン基またはアルコキシレン基を表わす、X1 −は陰イオンをそれぞれ表わす。
一般式(2)
R5は水素又はメチル基、R6、R7は炭素数1〜3のアルキル基あるいはヒドロキシアルキル基、X2 −は陰イオンをそれぞれ表わす。
(試料1〜3)
カチオン性高分子を含有した土壌固定化水溶液試料1〜3を調製し表1に示した。含有量は水溶液試料中のそれぞれの質量%を表す。土壌固定化水溶液試料1〜3を用いて、後述の項目を評価した。
表2に示す土壌固定化水溶液比較試料1〜2を調製した。含有量は水溶液試料中のそれぞれの質量%を表す。土壌固定化水溶液比較試料1〜2を用いて、後述の項目を評価した。
容器から取り出した時の土壌固定化サンプルの固化の様子を観察し、十分固化しているものを○、固化が不十分なものを×とした。
土壌固定化サンプルを水中に浸漬させたときの様子を観察し、固化状態を保持していたものを○、固化状態を維持できなかったものを×とした。
水分を4%程度含有する砂を半径7cm、高さ3cmのポリプロピレン製容器に550g敷き詰め、砂表面に表2で示す土壌固定化水溶液試料1〜2を均等に散布した。その後、50℃の乾燥機で24時間乾燥させ、固化した砂を容器から取り出し土壌固定化サンプルとした。土壌固定化サンプルを実施例1と同様に各項目を評価した。結果を表3に示す。
Claims (3)
- 下記(A)を含有する水溶液を土壌表面に散布することを特徴とする土壌浸食防止方法(ポリマーコンプレックスを形成する場合を除く)。
(A)下記一般式(2)で表されるカチオン性単量体を2〜100モル%、共重合可能な非イオン性単量体0〜98モル%を含有する単量体あるいは単量体混合物を重合したカチオン性高分子。
一般式(2)
R5は水素又はメチル基、R6、R7は炭素数1〜3のアルキル基あるいはヒドロキシアルキル基、X2 −は陰イオンをそれぞれ表わす。 - 前記(A)が、ポリジアリルジメチルアンモニウムクロリド、アクリルアミド−ジアリルジメチルアンモニウムクロリド共重合体から選択される一種以上であることを特徴とする請求項1に記載の土壌浸食防止方法。
- 前記(A)の重量平均分子量が1万〜300万であることを特徴とする請求項1あるいは2に記載の土壌浸食防止方法。
