Embodiment 1-1
[0030] 5L kneader, equipped with electric heating and temperature control, equipped with air inlet and vacuum outlet. In addition, it is equipped with ammonia absorption tank and vacuum system filled with sulfuric acid aqueous solution.
[0031] Add 10 moles of 1260 grams of melamine and 0.1 moles of 4.5 grams of ammonium dihydrogen phosphate into the above-mentioned 5L kneader, start stirring and heating, raise the temperature to 150°C, add 10 moles of 1050 grams of aminodiethylene glycol, and continue to heat up to 190°C , and nitrogen gas was introduced at the same time, and the reaction was carried out under stirring for 3 hours. During the reaction process, the amount of nitrogen added was controlled, and the exhaust valve was adjusted to stabilize the reaction pressure at 50 Pa. Thereafter, the vacuum was forced to deamination and dry for half an hour, and the temperature was kept at 190°C. Then continue to stir and lower the temperature until the reaction product drop...
Embodiment 1-2
[0035] Add 10 moles of 1260 grams of melamine and 0.5 moles of 95 grams of p-toluenesulfonic acid in a 5 L kneader as described in Example 1, start stirring and heating, heat up to 150° C., add metered 7 moles of 931 grams of aminodipropylene glycol, Continue to raise the temperature to 230° C. and feed nitrogen gas at the same time, and react for 4 hours under stirring. During the reaction process, the amount of nitrogen added was controlled, and the exhaust valve was adjusted to stabilize the reaction pressure at 25 Pa. Thereafter, the vacuum was forced to deamination and dry for half an hour, and the temperature was kept at 230°C. Then continue to stir and lower the temperature until the reaction product drops below 40°C, the product is in the form of powder, and the material is discharged when the particle size is less than 0.5mm. It takes about 2 hours to cool down to discharge. The primary component of the reactive plasticizing modifier is: hydroxypropyloxypropyl melam...
Embodiment 1-3
[0039] Add 10 moles of 1260 grams of melamine and 0.3 moles of 29.4 grams of phosphoric acid in a 5 L kneader as described in Example 1, start stirring and heating, heat up to 150 ° C, add metered 8 moles of 1064 grams of aminoisodipropylene glycol, and continue to heat up To 160° C., nitrogen gas was introduced at the same time, and the reaction was carried out under stirring for 4 hours. During the reaction process, the amount of nitrogen added was controlled, and the exhaust valve was adjusted to stabilize the reaction pressure at 0 Pa. Thereafter, vacuum forced deamination and drying was carried out for half an hour, and the temperature was kept at 160°C. Then continue to stir and lower the temperature until the reaction product drops below 40°C, the product is in the form of powder, and the material is discharged when the particle size is less than 0.5mm. It takes about 2 hours to cool down to discharge. The primary component of the reactive plasticizing modifier is: mo...
