Description

technical field [0001] The invention belongs to the technical field of chemical materials, and in particular relates to a polyurethane foam material used for packaging and a preparation method thereof. Background technique [0002] At present, polystyrene foam (EPS) materials are commonly used in the market for the packaging of various lighting and other fragile items, precision instruments, mechanical parts and other commodities. This type of material has certain shock absorption properties, but there are also many problems. : First, the degradability is poor, resulting in serious white pollution; second, the density of the material is relatively fixed and cannot be adjusted; another point is that this type of material often needs to be molded in advance, and the final product has a fixed shape and must be packaged according to the requirements. The shape of the item is customized first and the mold is re-produced. [0003] The polyurethane foam material is fast in forming...
