Description
分散剤としては、水硬性粉体に用いられるものが挙げられ、具体的には、リン酸エステル系重合体、ポリカルボン酸系共重合体、スルホン酸系共重合体、ナフタレン系重合体、メラミン系重合体、フェノール系重合体、リグニン系重合体等の水硬性粉体用の分散剤として知られているものが挙げられる。中でも、水硬性組成物の流動性向上の観点から、ポリカルボン酸系共重合体、ナフタレン系重合体及びリグニン系重合体が好ましく、(B)成分を添加しない場合よりも添加した場合に硬化開始までの時間が短い点で、ナフタレン系重合体が好ましい。
(B)成分は、タルトロン酸及び/またはその塩である。具体的には、下記一般式(1)で表される化合物である。
(1)モルタルの調製
表1に示す配合条件で、モルタルミキサー((株)関西機器製作所製記号KC−8製造番号9193)を用いて、セメント(C)、細骨材(S)を投入し回転速度60回転/分で空練りを10秒行った。その後、表2に示した種類及び量(有効分換算の量である)の(A)成分(分散剤)及び(B)成分又はオキシカルボン酸等の成分と、さらに消泡剤〔商品名「消泡剤No.21」、花王(株)製〕を含む練り水(W)を加え、回転速度60回転/分にて120秒本混練りした。空気連行量は2±1%となるよう消泡剤添加量にて調整した。消泡剤の最大添加量は、0.5gとして調整した。比較例1−1及び1−2は、消泡剤を0.5g加えても空気連行量を調整できなかったので、それ以上の空気連行量の調整はしていない。
・細骨材(S):城陽産、山砂、FM=2.67、密度2.56g/cm3
・水(W):水道水
・NSF:ナフタレンスルホン酸塩ホルムアルデヒド縮合物、花王(株)製 マイテイ150
・LS:リグニン系分散剤、ボレガード社製 ウルトラジンNA
・PCE:ポリカルボン酸系分散剤、(株)日本触媒製 FC-900
・タルトロン酸:シグマアルドリッチ製
・酒石酸ナトリウム:特級(+)−酒石酸ナトリウム二水和物 関東化学(株)製
・重炭酸ナトリウム:試薬特級炭酸水素ナトリウム 和光純薬工業(株)製
・グルコン酸ナトリウム:1st D−グルコン酸ナトリウム シグマアルドリッチ製
・蔗糖:三井製糖株式会社製 上白糖
モルタルについて、以下に示す試験法にしたがって、スランプフローをそれぞれ評価した。評価結果を表2に示した。

- (A’)成分と(B)成分の重量比〔(A’)/(B)〕が3.0〜60である請求項2記載の水硬性組成物。
- (A’)成分がポリカルボン酸系共重合体であり、(A’)成分と(B)成分の重量比〔(A’)/(B)〕が4.0〜18である請求項2又は3に記載の水硬性組成物。
- (A’)成分がリグニン系重合体であり、(A’)成分と(B)成分の重量比〔(A’)/(B)〕が6.2〜30である請求項2又は3に記載の水硬性組成物。
- 水と、水硬性粉体と、分散剤とを含有する水硬性組成物に、タルトロン酸及び/又はその塩を水硬性粉体100重量部に対して、0.007〜0.15重量部配合して、水硬性組成物の硬化遅延を生じることなく初期流動性を向上する方法。
