The application discloses a heat-triggered water-based carbodiimide crosslinking agent composition and application thereof. By introducing a latent acid and setting an alkaline environment during storage, the hydrolysis of carbodiimide and the pre-reaction of carbodiimide and carboxyl are simultaneously inhibited from the kinetic aspect, and the system is 'frozen' in a stable state. When used, the latent acid is triggered to decompose by heating, and the system pH is suddenly reduced to acidity by instantaneous release of protons, which not only quickly protonates and activates the carbodiimide, but also creates an optimal kinetic window in which the reaction rate of carbodiimide and carboxyl is much faster than the hydrolysis reaction, thereby accurately, synchronously and efficiently guiding the reaction path to the target crosslinking direction, and realizing the unification of'stable storage' and 'on-demand efficient reaction' in a single component.
