Aqueous fireproofing coating and its preparation process
By introducing multiple functional components into water-based fire-retardant coatings, a multi-level synergistic fire barrier is constructed and a self-healing function is introduced, which solves the problems of the single flame-retardant system and poor durability of existing water-based fire-retardant coatings, and achieves efficient, reliable fire protection and long-term use.

AI Technical Summary
Existing water-based fire-retardant coatings suffer from a single flame-retardant system, insufficient synergistic efficiency, an inability to balance physical and mechanical properties with fire-retardant properties, poor durability, and a lack of self-adaptive and self-healing capabilities, resulting in insufficient and unreliable fire protection.
The system employs a variety of components, including fluorosilicone epoxy hybrid emulsion, hydrophobic silica aerogel, composite microencapsulated flame retardant, composite bio-based charring agent, composite free radical scavenger, silane-modified cellulose nanofibers, short-cut basalt fiber, PCL fiber, and self-healing microcapsules. It constructs a multi-level synergistic fire protection system through gas-phase flame retardancy, condensed-phase flame retardancy, and high-efficiency thermal insulation mechanisms, and introduces a damage self-healing function.
It constructs an efficient multi-level fire barrier, improves the fire resistance limit and smoke suppression performance of the coating, takes into account physical and mechanical properties and long-term durability, has self-healing ability, and extends the service life of the fireproof coating.
