NOVELTY - Adhesive, comprises 80-100 pts. wt. waste molasses, 40-60 pts. wt. wheat gluten protein, 4-5 pts. wt. carbon nano tube, 10-15 pts. wt. graphene fiber, 5-10 pts. wt. silicon dioxide microsphere , 5-10 pts. wt. KH560 silane coupling agent, 3-4 pts. wt. sodium sulfite, 2-3 pts. wt. polyacrylamide, 0.05-2 pts. wt. phosphoric acid and 40-50 pts. wt. water USE - The adhesive is useful in preparing plywood. ADVANTAGE - The adhesive: is environmentally friendly; has excellent bonding strength, heat stability, thermal conductivity and heat curing rate; and does not contains formaldehyde. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: preparing the adhesive comprising (i) uniformly mixing the waste molasses, phosphoric acid and water, stirring at a low speed at a temperature of 70-80℃ and reacting for 1-1.5 hours, (ii) adding wheat gluten protein, carbon nano tubes and graphene fibers into the resultant reaction system and stirring at a low speed at a temperature of 60-80℃ and reacting for 1-2 hours, (iii) adding the silica microspheres and KH560 silane coupling agent into the resultant reaction system and stirring at a low temperature speed of 30-40℃ for 1-1.5 hours, (iv) adding sodium sulfite into the resultant reaction system and stirring at a high speed temperature of 80-90℃ for 0.5-1 hour, (v) reducing the temperature of the reaction system to room temperature, adding polyacrylamide into the reaction system and stirring the mixture at a low speed for 0.5-1 hour to obtain the product; and use of plywood comprising coating the adhesive on the single plate based on the vertical texture mode, assembling three layers of plywood, hot pressing and forming.
