Problems solved by technology

However, polyurethane has the disadvantage of poor heat resistance. When used under high temperature conditions, its mechanical properties drop significantly. In addition, as an organic polymer material, it is easy to burn, and its flame retardancy is not very ideal. It is also easy to hydrolyze and is not resistant to water. Poor surface properties limit the practical application of polyurethane materials

Description

technical field [0001] The invention relates to the technical field of polyurethane, in particular to a highly flame-retardant, heat-resistant and water-resistant polyurethane composite material. Background technique [0002] Polyurethane is a general term for compounds containing urethane groups in the molecule. More broadly speaking, in addition to urethane-based compounds, it also includes isocyanate compounds such as urea groups, allophanate groups, and biuret groups. All derived polymers have excellent properties such as wear resistance, oil resistance, tear resistance and chemical corrosion resistance, and are widely used in industrial and agricultural production, national defense construction and our daily life. However, polyurethane has the disadvantage of poor heat resistance. When used under high temperature conditions, its mechanical properties drop significantly. In addition, as an organic polymer material, it is easy to burn, and its flame retardancy is not very...
