2) modified melamine
改性三聚氰胺
1.
Based on the approach of molecular structure design,by way of adding a modifier in synthesis of sulfonate melamine formaldehyde condensate,a high molecular polymer side chain of prolongation was introduced into main struc- ture of the superplasticizer to form a modified melamine superplasticizer(SMS)with high dispersion and capacity for sustaining long time dispersion.

用三溴苯酚改性酚醛树脂、三聚氰胺改性酚醛树脂及松香改性树脂 ,将三者按一定的比例混合形成具有良好物理性能的阻燃树脂 ,同时也讨论了树脂各组分之间比例及其对混合树脂性能的影
6) MELAMINE /toxicity
三聚氰胺/毒性
补充资料:三聚氰胺苯代三聚氰胺共缩聚树脂
分子式:
CAS号:
性质:是由三聚氰胺、苯代三聚氰胺与甲醛和丁醇共缩聚制成的氨基树脂。由于用苯代三聚氰胺取代部分三聚氰胺,改进了三聚氰胺树脂与醇酸树脂的混溶性,提高涂膜的初始光泽、抗水性和耐碱性,但对三聚氰胺树脂的耐候性有不良影响。
