Abstract

The invention provides a bonding agent for starch-based corrugated paper and a preparation method thereof. The preparation method comprises the following steps: (1) preparing 8 to 12 percent sodium hydroxide and a 20 to 30 percent hydrogen peroxide solution, and performing ultrasonic oscillation to mix uniformly; (2) placing potato starch into a clean and dry reaction vessel, adding water, and stirring for 10 to 15 minutes at a speed of 80 to 160 revolution/minute until uniform mixing; (3) adding ferrous sulfate and the hydrogen peroxide solution, stirring for reacting for 10 to 20 minutes, adding the sodium hydroxide solution while stirring, and stirring and pasting until the shape of the solution does not change any more; (4) adding sodium borate and tributyl phosphate, and stirring continually for 20 to 30 minutes; (5) adding modified urea resin, ethylis oleas, ammonium oxide, modified konjac glucomannan, modified carrageenan and a preservative, and uniformly mixing to obtain the bonding agent. The bonding agent for the starch-based corrugated paper has very high viscosity and water resistance.

Description

technical field [0001] The invention relates to the field of adhesive manufacturing for packaging, in particular to an adhesive for starch-based corrugated paper and a preparation method thereof. Background technique [0002] Corrugated cartons are the most widely used packing boxes. In addition to the cardboard itself, the adhesive used is also an important factor affecting the quality of corrugated cartons. Although the sodium silicate aqueous solution adhesive used for many years has a simple operation process, it has disadvantages such as poor moisture resistance, slow bonding speed, and heavy carton. With the in-depth development of science and technology, the adhesive materials of corrugated cardboard and corrugated boxes are constantly updated and improved, and the sodium silicate solution that has been continuously used is no longer suitable for the needs of rapid packaging. After 1984, starch adhesives were widely used in my country, and such starch adhesives were ...
