NOVELTY - Preparing tree glue, comprises (i) mixing 15-25 pts. wt. polyethylene, 5-12 pts. wt. resin antibacterial agent, 5-12 pts. wt. polypropylene component and 5-8 pts. wt. graphene, and grinding, adding catalyst at high temperature and high pressure, and reacting for 10-23 minutes, and cooling, to obtain a first material; and (ii) adding 10-13 pts. wt. alcohol, 2-4 pts. wt. short fiber and 5-11 pts. wt. tetrafluoroethylene resin, and performing ultrasonic emulsification at ultrasonic frequency of 100-260 Hz for 2-6 minutes, to obtain second material, and mixing first material with second material. USE - The method is useful for preparing tree glue (claimed). ADVANTAGE - The method is simple, and economical; and utilizes less amount of raw materials. DETAILED DESCRIPTION - Preparing tree glue, comprises (i) uniformly mixing 15-25 pts. wt. polyethylene, 5-12 pts. wt. resin antibacterial agent, 1-3 pts. wt. polypropylene component and 5-8 pts. wt. graphene, and grinding, adding catalyst at a high temperature and high pressure, and reacting for 10-23 minutes, and cooling, to obtain a first material; and (ii) adding 10-13 pts. wt. alcohol, 2-4 pts. wt. short fiber and 5-11 pts. wt. tetrafluoroethylene resin, and carrying out ultrasonic emulsification under ultrasonic frequency of 100-260 Hz, for 2-6 minutes, to obtain second material, and mixing the first material with the second material, placing in clean water, and adjusting the mixture to statically indeterminate state.
