摘要
通过正交试验确定了以ZnO、H3 BO3 和H2 O合成 2ZnO· 3B2 O3 · 3.5H2 O的最佳工艺条件为 :ZnO∶H3 BO3 为 1∶3.1(mol) ,ZnO∶H2 O为 1∶33(mol) ,反应温度为 78℃ ,反应时间为 18h。产品经测定 ,脱水温度在 35 0℃～ 45 5℃ ,特别适用于高温下加工的高分子材料 ,这就为新型阻燃剂 2 335的实际应用奠定了理论基础。
By orthogonal test, the optimum technical conditions of the synthesis of 2ZnO·3B 2O 3·3.5H 2O with ZnO、H 3BO 3 and H 2O were determined as follows: ZnO∶H 3BO 3 = 1∶3.1(mol); ZnO∶H 2O = 1∶33(mol) ; reaction temperature 78 ℃; reaction time 18 h. The dehydration temperature of products was 350 ℃～455 ℃. This suggests that the product is especially suitable for the polymer materials processed at high temperatures, which lays a theoretical foundation for the practical application of new flame retardant 2335。
