Environment-friendly recyclable head-up display film material and preparation method thereof

The invention provides an environment-friendly recyclable head-up display film material and a preparation method thereof. The material is prepared from 0.05 wt% to 5.0 wt% of polyethylene terephthalate (PET), 0.2 wt% to 1.0 wt% of polylactic acid, 0.5 wt% to 2.0 wt% of polyketone, 1.0 wt% to 5.0 wt% of ethylene-vinyl acetate copolymer, 10.0 wt% to 20.0 wt% of triethylamine, 50.0 wt% to 80.0 wt% of polyvinyl butyral (PVB), 1.0 wt% to 5.0 wt% of aluminum hydroxide, 1.0 wt% to 5.0 wt% of a defoaming agent, 0.5 wt% to 1.5 wt% of a dispersing agent and water. According to the high-temperature-resistant head-up display film material provided by the invention, the raw material source of the polylactic acid in the material can be regenerated, no pollution is caused in the production of the polylactic acid, and the product can be biodegraded, so that circulation in nature is realized. The preparation method provided by the invention is simple and easy to implement, green and environment-friendly, can be used for large
