Abstract

The invention provides a production process for glue specially used for production of a corrugated board. The glue is formed by combining of two layers, i.e., glue A and glue B. The glue A is prepared by adding 90 to 100 parts by weight of water and 6 to 8 parts by weight of caustic soda in a reaction vessel, maintaining a temperature at 28 to 30 DEG C, carrying out stirring at the same time for 1 to 2 min, then adding 50 to 60 parts by weight of edible starch, carrying out stirring for 2 to 4 min, adding 0.5 to 0.7 part by weight of caustic soda and carrying out stirring for 30 to 60 sec. The glue B is prepared by selecting and weighing 4 to 6 parts by weight of resin or rubber, 2.5 to 3.5 parts by weight of nanometer metal particles and 1 to 2 parts by weight of starch, adding a proper amount of water and carrying out uniform mixing under stirring. The surface of the corrugated board is coated by the glue A at first and then by the glue B next. The special glue can effectively improve the bonding degree of the glue and guarantees bonding strength of layers of the corrugated board; moreover, in virtue of the glue B adhered on the outer surface of the glue A, surface performance of the corrugated board is changed, and waterproof strength and impact strength are improved.

Description

technical field [0001] The invention relates to a glue, in particular to a special glue for corrugated cardboard production line. Background technique [0002] At present, the online sales of various commodities are booming, which drives the development of the transportation industry. However, the requirements for packaging cardboard used for packaging products during transportation are getting higher and higher, especially in terms of waterproof, anti-collision and adhesion. For example, the patent application number: 201010222280.2 discloses a starch adhesive for producing corrugated cardboard and its preparation method. The process steps of the preparation method are: ① preparation of starch suspension; ② adding catalytic desiccant; ③ oxidation; ④ gelatinization ; ⑤ cross-linking; ⑥ modification; ⑦ defoaming. Its preparation process is relatively complicated, requires more raw materials, has high cost, takes a long time for preparation, consumes more manpower and materi...
