1.(コ)ポリマー(ポリマー噴霧助剤)の製造
ポリマー噴霧助剤の組成を表1にまとめる。
5%濃度のWako V50アゾ開始剤溶液(0.2モル%のアゾ開始剤に相当する)を、温度計、pHメーター及び還流凝縮器を備えた1リットルの4口フラスコ内に配置する。この混合物を、窒素のブランケット下で75℃まで加熱する。75℃に達した後、40%濃度の、2−アクリルアミド−2−メチルプロパンスルホン酸(AMPS)及びアクリル酸溶液(AA)(表1に対応する)の水性モノマー混合物と1モルの2−メルカプトエタノールを、60分間で同時に計量供給する。温度は冷却によって約80℃に維持する。添加が完了した後、撹拌を更に1時間80℃で継続する。これにより、35〜40質量%の固体含有率と2〜3.5のpHを有するわずかに黄色がかった、透明な水性(コ)ポリマー溶液が得られる。
本発明による液体組成物の製造の例:
液体促進剤CSH1:
合成のために、以下の成分を順番にガラスビーカー中に秤量し、簡単に混合した:
水ガラスBetol 39(Woellner) 14.3g
Ca(OH)2 (Alfa Aeser、99%) 4.9g
ポリマー2 10.0g
水 170.6g
促進剤2を、促進剤1と類似の方法で製造するが、合成のための組成物は次の通りであり、1mmの直径を有する500gのイットリウム安定化ZrO2ボールを含有する250mlのガラスフラスコを使用した:
水ガラスBetol39(Woellner) 7.2g
Ca(OH)2(Alfa Aeser、99%) 2.4g
ポリマー3 5.0g
水 85.4g
硬化促進剤として作用する得られた組成物の特性決定を、TA Instruments社製のTamAir熱量計を用いて等温熱流熱量測定法によって行った。ここで、硬化促進剤を用いて又は用いずにセメントペーストを製造し、20℃で22時間の硬化の間の熱の発生を監視した。セメントとして、Cem I 52.5Rセメントを使用した。
本発明による促進剤組成物の有効性を、標準的なモルタルで6時間の圧縮強度によっても決定した(DIN EN196−1に類似のプリズム)。この結果を表2にまとめる。
450gのセメント(CEM I 52.5 R)
1350gの標準砂
225gの水
本発明による固体組成物(粒状の促進剤)の製造:
これらを以下の一般的な方法に従って製造した:
X−Seed(登録商標)−100(BASF Construction Chemicals GmbH)を出発材料として使用した。懸濁液を、X−Seed(登録商標)−100の固体含有率(固体含有率は21.7質量%)を基準として5質量%の噴霧助剤(表1の添加剤)と乾燥前に10分間混合した。形成された懸濁液を、窒素雰囲気下で160℃の入口温度で及び50〜60℃の出口温度でNiro社製の乾燥機を用いて噴霧乾燥により粉末状態に転換した。
本発明による促進剤組成物の有効性を、標準モルタル中で6時間の圧縮強度によって測定した(DIN EN 196−1に類似のプリズム)。種々の促進剤を用いて測定の比較を可能にするために、モルタルに添加する量を、いずれの場合も、セメントの質量を基準として、1.44質量%のX−Seed(登録商標)100からの固体が実験3及び実験12〜17で添加されるように選択した。これは、当然ながら、X−Seed(登録商標)100がそれ自体添加されないが(比較実験2のように)、その代わり、対応する量の固体含有率の出発材料X−Seed(登録商標)100が処理されるべき粉末状生成物の形で添加されることを意味する。
