Abstract
Description
ベースフィルム形成モノマーは、固体セメント添加剤に塗布されて、固体セメント添加剤を取り囲むコーティング層を形成する。コーティング層は、固体セメント添加剤の各固体粒子をコーティングし、取り囲む。コーティング層中のベースフィルム形成モノマーの量は、固体セメント添加剤の約1wt%〜約25wt%であり得る。
オーバーレイモノマーは、固体セメント添加剤を取り囲むコーティング層に塗布することができる。コーティング層に塗布されるオーバーレイフィルム形成モノマーの量は、固体セメント添加剤の約1wt%〜約40wt%の範囲であり得る。オーバーレイフィルム形成モノマーは、流体乾式コーティング法を用いてオーバーレイモノマー流体として、あるいは熱間圧延法による乾式コーティングを用いて固体オーバーレイモノマーとして塗布することができる。
オーバーレイフィルム形成モノマーは、ベースフィルム形成モノマーと反応して、ポリマーシェルを生成し、ポリマーシェルは、架橋ポリマーを含有する。少なくとも1つの実施形態では、ポリマーシェルは、固体粒子が撹拌されている間に形成される。架橋ポリマーは、ポリマーシェルを形成する固体セメント添加剤を取り囲む。コーティング層を有する固体セメント添加剤は、架橋ポリマーを生成する反応が起こっている間に蒸気除去に供することができる。蒸気除去方法は、プロセスを真空下に置くこと、または不活性ガス流、または空気を固体セメント添加剤の上に流すことを含み得る。
[封入された添加剤の製造方法]
封入された添加剤サンプルを2つの異なる乾式コーティング法によって調製した。固体セメント添加剤はセメント分散剤であった。セメント分散剤は、その強い比色シグナルのために使用される、赤色粉末のスルホン化アセトン−ホルムアルデヒド縮合物(SAFC)であった。使用した親水性モノマーは、1,6−ヘキサンジアミン(HDA)であった。使用した疎水性モノマーは、1,3,5−ベンゼントリカルボニルトリクロリド(BTCAC)であった。表1に示す各モノマーの量でサンプルを調製した。
水性媒体中の封入された添加剤の徐放性を2つの方法で評価した。第1の方法は、方法1によって生成された封入された添加剤のサンプル1粒子を水のビーカに入れ、封入された添加剤からの水中への色筋模様の拡散を観察する目視手段によるものであった。
