Title:
NANO ZIRCONIUM PHOSPHATE-BASED FLAME-RETARDANT BACTERIOSTATIC AGENT AND INTUMESCENT FIREPROOF ANTIBACTERIAL COATING PREPARED THEREFROM
Document Type and Number:
WIPO Patent Application WO/2023/039939
Kind Code:
A1
Abstract:
Disclosed in the present invention is a nano zirconium phosphate-based flame-retardant bacteriostatic agent. Intercalation stripping is performed on zirconium phosphate first, and zirconium phosphate is modified by using aminoimidazole and chloropropionaldehyde to prepare a flame-retardant bacteriostatic agent based on nano zirconium phosphate capable of playing a synergistic flame-retardant role with an intumescent flame-retardant system in a fireproof coating while effectively solving problems such as easy agglomeration of zirconium phosphate, and remarkably improving the film-forming properties, fire resistance and durability of the obtained fireproof coating. Schiff base and imidazole loaded on the surface of a nano zirconium phosphate layer can be more uniformly dispersed in coating components, so that a barrier bacteriostatic effect is achieved, and Schiff base, nano zirconium phosphate and imidazole in the flame retardant can effectively improve the antibacterial properties of the fireproof coating. The flame retardant obtained in the present invention integrates flame retardance, smoke suppression, bacteriostasis and enhancement functions, and is low in halogen-free cost, good in char forming properties, environment-friendly, and wide in applicability, and a related preparation method is simple in process, simple in reaction conditions and suitable for popularization and application.
