NOVELTY - Environment-friendly high temperature resistant adhesive comprises soybean protein, hyperbranched polyamide, polyamide polyamine epichlorohydrin, graphene oxide, aluminum dihydrogen phosphate, de-ionized water. The environment-friendly high temperature resistant adhesive is prepared by adding the graphene oxide into de-ionized water, using cell crushing instrument for ultrasonic dispersing the solution, transferring it to three-mouth flask equipped with a stirrer and a condensing pipe, slowly dropping the hyperbranched polyamide solution at stirring speed of 150-200 revolution/minute (r/min), reacting for 0.8-1.5 hours at 70-80 degrees C of water bath heating, then cooling to room temperature, stirring reaction solution at 8000-9000 r/min, separating and centrifuging for 4-10 minutes, and using de-ionized water to wash for 2-3 times. USE - Environment-friendly high temperature resistant adhesive used for wall decorative plate. ADVANTAGE - The environment-friendly high temperature resistant adhesive improves the waterproof adhesive strength and heat resistance of the soybean protein adhesive. DETAILED DESCRIPTION - Environment-friendly high temperature resistant adhesive comprises soybean protein, hyperbranched polyamide, polyamide polyamine epichlorohydrin, graphene oxide, aluminum dihydrogen phosphate, de-ionized water. The environment-friendly high temperature resistant adhesive is prepared by adding the graphene oxide into de-ionized water, using cell crushing instrument for ultrasonic dispersing the solution, transferring it to three-mouth flask equipped with a stirrer and a condensing pipe, slowly dropping the hyperbranched polyamide solution at stirring speed of 150-200 revolution/minute (r/min), reacting for 0.8-1.5 hours at 70-80 degrees C of water bath heating, then cooling to room temperature, stirring reaction solution at 8000-9000 r/min, separating and centrifuging for 4-10 minutes, and using de-ionized water to wash for 2-3 times, obtaining hyperbranched polyamide modified graphene oxide, adding the hyper-branched polyamide modified graphene oxide into de-ionized water for ultrasonic dispersing for 1 hours, then adding the soybean protein for the 2-4 times, stirring for 3-8 minutes, ultrasonically vibrating for 8-15 minutes, then adding polyamide polyamine epichlorohydrin, obtaining reaction liquid, adding the aluminum dihydrogen phosphate solution to the reaction liquid to mix uniformly, where adding mass of the aluminum dihydrogen phosphate solution is 1.2-1.8 times of the mass of the reaction liquid, stirring for 3-8 minutes at 150-200 r/min to obtain finished product.
