Embodiment 1
[0033] (1) The synthetic steps of triazine series char-forming-foaming agent:
[0034] ①Add 350 grams of cyanuric chloride and 500 grams of acetone to the reaction kettle to disperse the cyanuric chloride evenly, and add 50 grams of ethanolamine and 30 grams of triethylamine dropwise at -5°C to 5°C until the pH of the solution is 5~7, react for 1~3 hours after the dropwise addition is completed;
[0035] ②Raise the temperature to room temperature, add 60 grams of ethylenediamine and 15 grams of triethylamine dropwise, keep the pH value of the solution at 5-7, raise the reaction temperature to 40°C-65°C after the dropwise addition, and react for 4-6 hours ;
[0036] ③Raise the reaction temperature, and add 60 grams of ethylenediamine and 15 grams of triethylamine dropwise into the reaction kettle at 80°C to 110°C, so that the pH of the solution is 5 to 7, and after 5 to 7 hours of reaction The acetone was distilled off, and the product was washed with water, suction filtered,...
