Study on Thermal Insulation Performance of Prefabricated Greenhouse Degradable Polystyrene Composite Plastic Materials
Polystyrene composites were prepared by blending nano glass fibers with polystyrene, and the effects of nano glass fiber content on the mechanical and thermal insulation properties of polystyrene composites were investigated. The results show that the addition of nano glass fibers effectively improve the mechanical properties, flame retardancy, and insulation properties of polystyrene composites. By appropriately increasing the content of nano glass fibers, the mechanical properties, flame retardancy, thermal insulation of polystyrene composites can be effectively improved, while enhancing their degradability. When the mass fraction of nano glass fibers is 20%, the compressive strength and notch impact strength of polystyrene composites increase by 57.26% and 17.43%, respectively, compared to pure polystyrene, and the limited oxygen index (LOI) value increases by 48.07%.
