Description

technical field [0001] The invention relates to the technical field of foamed plastics, in particular to a high-hardness, impact-resistant, heat-insulating foamed plastic. Background technique [0002] Foamed plastic is obtained by foaming plastic. Foam molding is the process of creating a microcellular structure in plastics. Almost all thermosetting and thermoplastic plastics can be made into foam plastics. Commonly used resins are polystyrene, polyurethane, polyvinyl chloride, polyethylene, urea-formaldehyde, phenolic and so on. Existing foamed plastics are often used for heat insulation, but the effect is not ideal, and it is difficult to unify the impact resistance and hardness of the foamed plastics. Contents of the invention [0003] The technical problems in the basic background technology, the present invention proposes a high-hardness, impact-resistant and heat-insulating foamed plastic, which has uniform impact resistance and hardness, excellent heat insulation...
