Abstract

A microcapsule, a preparation method therefor, and a use thereof. The microcapsule comprises a capsule core and a capsule wall. The capsule core is wrapped in the capsule wall. The capsule core contains an active component. The elastic modulus of the microcapsule and the thickness of the capsule wall satisfy the following formula: Y=0.42X<2>-0.92X+T, wherein Y is the elastic modulus of the microcapsule, and the unit thereof is GPa; X is the thickness of the capsule wall, and the unit thereof is µm; and T is 1±0.1. The elastic modulus of the microcapsule is obtained by performing a mechanical property test on the microcapsule by using a nano-indentation instrument. The thickness of the capsule wall is obtained by performing frozen section on the microcapsule by using a scanning electron microscope. The microcapsule is suitable for pavement asphalt, and the self-repairing efficiency of a pavement asphalt material can be effectively improved. In addition, in a process of asphalt construction, the emission of an asphalt flue gas can be effectively reduced and the pollution to the environment is reduced.
