Embodiment 1
[0023] A water-based polyurethane adhesive for high-strength fiber composite materials. Add water-based PUR dispersion to the adhesive and mix it, then add it to the slurry tank for drying. The drying temperature is 60°C to obtain a water-based polyurethane adhesive for high-strength fiber composite materials. Water-based PUR The amount of the dispersion added is 10% of the weight of the adhesive; the adhesive is a water-based adhesive, and the weight ratio of the adhesive to water is 20%.
[0024] Aqueous PUR dispersions are prepared as follows:
[0025] (1) Put the dried polyether polyol into the container, add toluene diisocyanate to the container and react at 65°C for 2 hours, then add N-methyl-2 dimethylolpropionic acid dissolved in the container dropwise -Pyrrolidone was reacted at 55°C for 2 hours to obtain a prepolymer; the addition of toluene diisocyanate was 15% of the weight of polyether polyol; the addition of dimethylol propionic acid was 15% of the weight of N-me...
Embodiment 2
[0029] A water-based polyurethane adhesive for high-strength fiber composite materials. Add water-based PUR dispersion to the adhesive and mix it, then add it to the slurry tank for drying. The drying temperature is 70°C to obtain a water-based polyurethane adhesive for high-strength fiber composite materials. Water-based PUR The amount of the dispersion added is 12% of the weight of the adhesive; the adhesive is a water-based adhesive, and the weight ratio of the adhesive to water is 40%.
[0030] Aqueous PUR dispersions are prepared as follows:
[0031] (1) Put the dried polyether polyol into a container, add toluene diisocyanate to the container and react at 68°C for 2.5 hours, then add N-methyl-2 dimethylolpropionic acid dissolved in the container dropwise -Pyrrolidone was reacted at 58°C for 2.5 hours to obtain a prepolymer; the addition of toluene diisocyanate was 18% of the weight of polyether polyol; the addition of dimethylol propionic acid was 18% of the weight of N-...

[0035] A water-based polyurethane adhesive for high-strength fiber composite materials. Add water-based PUR dispersion to the adhesive and mix it, then add it to the slurry tank for drying, and the drying temperature is 80°C to obtain a water-based polyurethane adhesive for high-strength fiber composite materials. Water-based PUR The amount of the dispersion added is 15% of the weight of the adhesive; the adhesive is a water-based adhesive, and the weight ratio of the adhesive to water is 60%.
[0036] Aqueous PUR dispersions are prepared as follows:
[0037] (1) Put the dried polyether polyol into the container, add toluene diisocyanate to the container and react at 70°C for 3 hours, then add N-methyl-2 dimethylolpropionic acid dissolved in the container dropwise -Pyrrolidone was reacted at 60°C for 3 hours to obtain a prepolymer; the addition of toluene diisocyanate was 20% of the weight of polyether polyol; the addition of dimethylol propionic acid was 20% of the weight of ...
