Abstract

The invention relates to a TPU modified impact-resistant transparent composite material and a preparation method thereof, and belongs to the technical field of composite materials. The TPU modified impact-resistant transparent composite material is prepared from the following raw materials in parts by mass: 50 to 70 parts of thermoplastic polyurethane, 50 to 70 parts of transparent base material and 0.5 to 1 part of metal oxide, the TPU modified impact-resistant transparent composite material disclosed by the invention not only has good impact resistance and flame-retardant property, but alsokeeps extremely high transparency, and meanwhile, a shell structure is expanded to more material fields; the invention also provides a simple and feasible preparation method.

Description

technical field [0001] The invention relates to a TPU modified impact-resistant transparent composite material and a preparation method thereof, belonging to the technical field of composite materials. Background technique [0002] Due to the unique multi-level layered structure, shells in nature naturally have excellent tensile and impact resistance and sufficient toughness. Compared with synthetic composite materials, shells not only have outstanding performance, but also have the advantages of maximizing the use of natural resources and minimizing energy requirements to build complex reinforced structures, so the imitation of shell-like composite materials greatly attracts researchers. eyeball. After exploring the reason for its enhancement, it was found that the structure of the shell is composed of a large number of inorganic nanosheets and adhesive shell substances, which endow the shell with unparalleled mechanical properties through mechanisms such as sliding, bridg...
