Embodiment Construction
[0010] The technical solutions of the present invention will be further described below in combination with specific preferred embodiments.
[0011] A high-efficiency, environmentally friendly and smoke-suppressing wood flame retardant, its components are proportioned by mass percentage: 20% phosphoric acid, 12% dicyandiamide, 40% ammonium dihydrogen phosphate, 10% zinc borate, 10% antimony oxide, molybdenum Ammonium Acid 5%, Sodium Alkane Sulfonate 2%, Pentaerythritol 1%. Wherein, the mass concentration of the phosphoric acid is 80%-90%.
[0012] The preparation method is as follows: (1) Weigh each component according to the mass percentage ratio; (2) Add dicyandiamide and water to prepare an aqueous solution with a mass concentration of 20% to 40%, and mix it under 70°C to 90°C under stirring conditions. Slowly add phosphoric acid under low temperature, react at constant temperature for 0.5-2 hours to obtain amidinourea phosphate GUP, then add ammonium dihydrogen phosphate,...
