Abstract

ABSTRACTPolyurea coatings are widely used in various industries due to their excellent mechanical properties, such as high tensile strength, abrasion resistance, and chemical resistance. However, their lack of inherent flame retardancy limits their use in applications where fire safety is critical. Therefore, reinforcing the fire‐retardant properties of traditional polyurea through various means can effectively protect the product while reducing the risk of fire. This paper provides a summary of several advanced methods for improving flame retardancy. It systematically analyzes the advantages and disadvantages of these methods and proposes improvement measures to enhance efficiency. Additionally, the paper proposes new methods to increase the fire resistance of polyurea. These include the addition of new flame‐retardant additives and the substitution of the backbone of polyurea, making it suitable for more industrial applications. This mini‐review can also serve as a valuable reference for future research on improving the flame retardancy of elastomeric polyurea materials.
