Example Embodiment
[0015] Example 1: A new type of paperboard adhesive, which is composed of a mixture of water, tapioca starch, sodium hydroxide, enhancer, and borax. The mass ratio of each component is 84% water and 13% tapioca starch. Sodium hydroxide 1%, enhancer 1.8%, borax 0.2%. The reinforcing agent may be epoxy resin or the like. In this embodiment, epoxy resin is used.
[0016] The preparation method is as follows:
[0017] a. Add water to the first mixing tank, first add one-seventh of the total amount of tapioca starch, stir for 10-15 minutes to make it evenly mixed;
[0018] b. Add sodium hydroxide to the first mixing tank and mix evenly to make mature glue;
[0019] c. Pour water into the second mixing tank, add enhancer, and add the remaining six-sevenths of the tapioca starch, stir and mix evenly to make raw rubber;
[0020] d. Pour the cooked glue in the first mixing tank into the second mixing tank and stir for 15-20 minutes;
[0021] e. Finally, inject borax water prepared by dilutin...
Example Embodiment
[0022] Example 2: A new type of paperboard adhesive, which is composed of water, tapioca starch, sodium hydroxide, epoxy resin, and borax. The mass ratio of each component is: water 81%, tapioca starch 17% , Sodium hydroxide 0.5%, epoxy resin 1%, borax 0.5%. The preparation method of the adhesive is the same as in Example 1.
