NOVELTY - Endothermic adhesive film comprises 60-85 pts. wt. film base made of film adhesive, 1-20 pts. wt. heat-conducting material set as a carbon material and evenly distributed in the adhesive film matrix, endothermic material set as a powder material and evenly distributed in the adhesive film matrix, and the endothermic material undergoes a decomposition reaction under heated conditions to absorb heat, where the content of the heat absorption material is 5-20 pts. wt. USE - The adhesive film is used as the bonding material of the bulletproof board. ADVANTAGE - The adhesive film decomposes after being heated and absorbs lot of heat, prevents the polymer material in the bulletproof insert from being severely ablated, effectively maintains its energy absorption effect, and improves the bulletproof ability of the bulletproof insert. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the endothermic adhesive film involving mixing adhesive film adhesive, heat-conducting material and heat-absorbing material with appropriate amount of defoamer and solvent, ball milling to obtain casting slurry, casting the slurry to obtain a film and drying the adhesive film to obtain an endothermic adhesive film.
