Embodiment 1

[0015] Embodiment 1: a kind of novel cardboard adhesive, this adhesive is made up of mixing water, tapioca starch, sodium hydroxide, strengthening agent, borax, and the mass ratio of each component is: water 84%, tapioca starch 13%, Sodium hydroxide 1%, enhancer 1.8%, borax 0.2%. As the reinforcing agent, epoxy resin or the like can be used. 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, and stir for 10-15 minutes to make it evenly mixed;

[0018] b. Add sodium hydroxide into the first mixing tank, stir evenly, and make mature glue;

[0019] c. Inject water into the second mixing tank, add the enhancer, and add the remaining 6 / 7 of the tapioca starch, stir and mix evenly to make raw rubber;

[0020] d. Inject the cooked glue in the first mixing tank into the second mixing tank and stir for 15-20 minutes;

[0021] e. Finally ...

Embodiment 2

[0022] Embodiment 2: A kind of novel cardboard adhesive, this adhesive is made up of water, tapioca starch, sodium hydroxide, epoxy resin, borax mixing, and 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.

Embodiment 3

[0023] Embodiment 3: A kind of novel cardboard adhesive, the component of this adhesive and mass ratio are: water 80%, tapioca starch 18%, sodium hydroxide 0.5%, reinforcing agent 1%, borax 0.5%. The preparation method of the adhesive is the same as in Example 1.

Abstract

The invention relates to a novel paperboard adhesive and a preparation method thereof. The adhesive is composed of the following components in percentage by mass: 75-85% of water, 13-21% of cassava starch, 0.2-1.0% of sodium hydroxide, 0.7-2.0% of reinforcer and 0.2-1.0% of borax. The adhesive has the advantages of high adhesive capacity, favorable compression resistance, favorable moisture resistance and high drying speed, and can enhance the quality of the bonded paperboard and improve the production efficiency. The preparation method of the adhesive is scientific and reasonable, and fully considers the property characteristics of the components. Reasonable steps and processes are adopted to obtain the adhesive with excellent properties.

Description

technical field [0001] The invention belongs to the technical field of cardboard adhesive and its preparation method. Background technique [0002] Adhesive is an essential material for cardboard production enterprises.
