Problems solved by technology
[0002] In the existing technology of corrugated cardboard assembly line production equipment, the adhesive used is generally starch glue. Starch glue is widely used due to its low price, simple glue making process, fast drying speed, and adaptability to the production requirements of the Soviet Union. The corrugated paper industry at home and abroad, but the original starch glue has the following problems, the glue is prone to precipitation during use, it is easy to change and damage during high temperature, and the adhesion performance is not high, resulting in waste of glue in the production process and poor cardboard performance. Unstable, in order to improve its performance, the starch glue is modified by using alum, amine, sodium hypochlorite, sodium stearate, sodium bisulfite, etc. to modify the starch. Although the effect is better, there is still a glue making process Complicated, difficult source of raw materials and other issues

Abstract
The invention provides a corrugated board adhesive glue. The adhesive glue comprises the following raw materials, by weight, 400-600 parts of water, 80-120 parts of corn starch, 4-6 parts of polyvinyl alcohol, 0.8-1.2 parts of sodium borate and 8-12 parts of sodium hydroxide solution. The adhesive glue is advantaged by simple process, simple operation, low-cost raw materials, low-temperature technology requirement and firm adhesion.
Description
technical field [0001] The invention relates to the technical field of adhesive glue, in particular to a corrugated cardboard adhesive glue and a preparation method thereof. Background technique [0002] In the existing technology of corrugated cardboard assembly line production equipment, the adhesive used is generally starch glue. Starch glue is widely used due to its low price, simple glue making process, fast drying speed, and adaptability to the production requirements of the Soviet Union. The corrugated paper industry at home and abroad, but the original starch glue has the following problems, the rubber is easy to precipitate during use, it is easy to change and damage during high temperature, and the adhesion performance is not high, resulting in waste of rubber in the production process and poor cardboard performance. Unstable, in order to improve its performance, the starch glue is modified by using alum, amine, sodium hypochlorite, sodium stearate, sodium bisulfit...
