Water-extended polyesteramides are produced by forming a water-in-oil emulsion of the polyesteramide and thereafter curing the polyesteramide emulsion. When halogen-containing polyesteramides are used, a synergistic fire-retardancy effect is achieved. Substantially water-insoluble metal oxides, such as zinc oxide and magnesium oxide, are used as emulsifying agents to produce room temperature curable polyesteramide and polyester emulsions which, after curing, have desirable hardness and fire-retardancy characteristics.
水延伸聚酯酰胺是通过形成聚酯酰胺的水包油乳液,然后固化聚酯酰胺乳液来制造的。当使用含卤素的聚酯酰胺时,可以实现协同阻燃效果。基本上不溶于水的金属氧化物,如氧化锌和氧化镁,被用作乳化剂,以生产室温可固化的聚酯酰胺和聚酯乳液,固化后具有理想的硬度和阻燃特性。
