The invention provides a durable biomass polyphenol water-based flame-retardant coating and its preparation method and application. The water-based flame-retardant coating is mainly composed of biomass polyphenols or biomass polyphenols and salts through coordination bonds or/and Adsorption composition, its preparation method is by mixing biomass polyphenols with appropriate amount of water, or adding binder on this basis; or by mixing biomass polyphenols with appropriate amount of water and adding salt solution dropwise, or on this basis Then add the binder to get. The preparation method of the biomass polyphenol water-based flame-retardant coating has low energy consumption, environmental protection and safety, and the prepared biomass polyphenol water-based flame-retardant coating has durability, high flame-retardant efficiency, strong adhesion, environmental protection and safety, and can not only directly It can be used as a water-based flame retardant coating, and can also be used as a surface treatment and additive flame retardant for different types of polymer materials. |
