| 20100305235 | Anticorrosive Nanocomposite Coating Material, and a Preparation Process Thereof - The invention relates to an anticorrosive nanocomposite coating material that comprises polyurea, organophilic clay and suitable additives, and is useful for preparing a polyurea/clay nanocomposites; whereby said nanocomposite coating material is coated on a substrate to greatly decrease the corrosion rate of the substrate; wherein said polyurea is combined from an amino terminated compounds and a isocyanate compound. The invention also provides a process for preparing said nanocomposite coating material, said process comprising: mixing homogeneously said amino terminated compound and an organophilic clay, followed by mixing homogeneously with isocyanate compound and suitable additives at a proper ratio, wherein, after a polymerization reaction, said organophilic clay can achieve a nano-scale dispersion extent, thereby obtaining said anticorrosive nanocomposite coating material. | 12-02-2010 |
