Example Embodiment
[0029] Example 1:
[0030] According to the molar ratio, add 526 parts of m-cresol, 263 parts of xylene, and 87 parts of butanol into a reactor with a stirrer and a reflux tube. When the temperature reaches 65℃, add 100 parts of nylon 12 gradually and uniformly within 0.5 hours, while stirring and heating, and keep the temperature at 115℃ for 2 hours to obtain semi-finished product A; then semi-finished product A is cooled, the temperature is controlled at 75℃, and epoxy resin is added 18 parts, keep the temperature at 75°C for 1.5 hours, then lower the temperature to 65°C, add 6 parts of organic silicon, keep the temperature at 65°C for 0.5 hours, add 0.3 parts of polyether modified polyoxymethylene siloxane, 0.5 parts of polymer wax and stir Evenly, product B is obtained; the temperature of product B is lowered to 55°C, and 1 part of acidification preventive agent dioctadecyl thiodipropionate is added, and the temperature is maintained at 55°C and the stirring is continued for 0...
