Linseed oil-loaded microcapsule-based self-healing protective coatings for cementitious materials |
초록 |
Self-healing protective coating materials have the ability of autonomic self-healing of region damaged by microcracking in the coatings themselves or substrate materials such as metals or concrete. Linseed oil undergoes an oxidative drying reaction, affording a soft film. Linseed oil-loaded microcapsules were prepared using a urea-formaldehyde resin as the microcapsule wall material. The microcapsules were characterized by optical microscopy and SEM. The microcapsules were dispersed into a commercial protective coating formulation to prepare self-healing coating. The self-healing function of the coating was investigated by SEM, a water sorptivity test and an accelerated carbonation test at room temperature and saline solution sorptivity test at low temperature for both scratches and crack damage in the coatings. The linseed-oil-based microcapsule-type self-healing coating system is demonstrated as a protective coating for cementitious materials. |
