High-strength corrugated case binder and production method thereof
A corrugated box, adhesive technology, applied in the direction of polymer adhesive additives, non-polymer adhesive additives, adhesive types, etc., can solve the problem that the storage time is short, usually about 24 hours, and the kinematic viscosity of the glue decreases. Faster, the adhesive is not stable, etc., to achieve the effect of not easy to separate the water and glue, good bonding performance, and stable product quality

[0039] The preparation method of described high-strength corrugated box adhesive comprises the steps:
[0040] Step 1. Under constant stirring at 150r / min, use the discharge device to slowly add soybean protein isolate into the NaOH solution. After the addition, gradually raise the temperature of the system to 80°C within 25-30min, keep the temperature for 90min, and then cool down to 50°C, adjust the pH of the system to 9-9.5 with citric acid, and naturally cool to room temperature to obtain a soybean protein degradation solution;
[0041] Step 2. React the soybean protein degradation solution with one-third of the modified phenolic resin at 90°C for 10 minutes, then lower the temperature to 65°C, add the remaining modified phenolic resin and modified lignin, continue the reaction for 20 minutes, and cool naturally to room temperature to prepare the adhesive.
[0042] The discharge device described in step 1, such as Figure 1-3 As shown, including the discharge barrel 1, t...
