The invention provides a polyurethane foam material for a cylindrical battery module as well as a preparation method and application thereof, the polyurethane foam material comprises a component A and a component B. The component A comprises polymer polyol A, a foaming agent, a halogen-free flame retardant and a catalyst; and the component B comprises polymer polyol B, isocyanate and a tackifier. The polyurethane foaming material provided by the invention has lower viscosity and longer reaction time before foaming forming, further has longer operable time, and has higher strength, lower heat conductivity coefficient, excellent flame retardant property and lower density after foaming forming, so that the fixing effect and thermal protection on a battery cell module can be enhanced, and the service life of the battery cell module is prolonged. And meanwhile, the design requirement of light weight is met, and the battery cell module is suitable for industrial production. 本发明提供一种用于圆柱电池模组的聚氨酯发泡材料及其制备方法和应用，所述聚氨酯发泡材
