| 摘 要： | 采用苯酚对三聚氰胺-甲醛树脂(MF)进行改性,研究了3种原料(苯酚、三聚氰胺和甲醛)不同配比下的合成产物的模塑料性能,优选出低酚摩尔分数(8%)的用于模塑料加工的苯酚改性蜜胺树脂(PMF)。该树脂中甲醛与三聚氰胺的物质的量比(F1/M)为1.75∶1,甲醛与苯酚的物质的量比(F2/P)为1.7∶1,甲醛和苯酚的物质的量之和与三聚氰胺物质的量比((F1+F2+P)/M)为2.5∶1。该树脂可提高模塑料的加工性能,降低加工能量损耗,改善制品的模塑性和耐冲击性。

| Abstract: | The melamine-formaldehyde resin(MF) was modified by phenol.The molding properties of synthetic products from different ratios of three raw material (phenol, melamine and formaldehyde) were investigated.The optimal phenol modified MF(PMF)with low phenol mole fraction(8%) for molding materials was selected. In this resin the molar ratio of formaldehyde to melamine(F1/M),formaldehyde to phenol(F2/P),sum of formaldehyde and phenol to melamine((F1+F2+P)/M)was 1.75/1,1.7/1 and of molding materials and reduce the processing energy loss,The moldability and impact resistance of product were improved. |
