Description

technical field [0001] The invention relates to a rigid polyurethane foam material used for a light truck fuel tank and a preparation method thereof. Background technique [0002] At present, with the development of the light truck industry and the enhancement of people's awareness of safety and environmental protection, people's requirements for light truck components have also increased significantly. Light truck fuel tanks must have the characteristics of high temperature resistance, high flame retardancy, high strength, light weight, and high environmental protection . Traditional light truck fuel tanks usually cannot achieve ideal results. In the event of an accident, the poor flame retardancy will lead to short escape time for personnel, which poses a great safety hazard. Therefore, it is the goal that this field has been pursuing to explore high-strength, high flame-retardant, high-environmental protection flame-retardant foaming materials.
