The invention discloses a composite material with shape memory function, a preparation method and application thereof. The composite material comprises four layers, which are: surface decorative layer, protective layer, adhesive layer and soft lining; the protective layer is plastic or vulcanized plastic; the plastic is softened by heat above 55 ° C, and the temperature is lower than 55 ° C. Crystal hardening; soft lining is foamed plastic, rubber or foamed rubber; soft lining and protective layer are connected by adhesive layer; the surface decorative layer is coating layer. The invention utilizes the material shape memory principle, and the temperature rise of 60 ° C or above, the crystallization of the material such as eucommia gum is changed into an amorphous state, and the principle of free shaping can be adopted, and the individual shaping and vulcanization processes are used to prepare the personalized protection. With or with disabilities. The prepared protective gear or accessory can adjust the personalized device that fits the shape of the human body according to different groups of people. |
