FLAME RETARDANT COMPOSITION FOR FLAMMABLE PLASTIC MATERIALS COMPRISING 2,4,6-TRIS(2,4,6-TRIBROMOPHENOXY)-1,3,5- TRIAZINE AND PROCESS FOR PRODUCING THE SAME |
摘要 |
A flame retardant composition for flammable plastic materials and a method for producing the same are disclosed. The flame retardant composition comprises 2,4,6-tris(2,4,6-tribromophenoxy)-1,3,5-triazine that contains 1 to 1000 ppm of a metal species of a water-insoluble polyvalent metal compound selected from the group consisting of oxide, hydroxide, carbonate, phosphate, sulfate and silicate present in the particles of 2,4,6-tris(2,4,6-tribromophenoxy)-1,3,5-triazine. The flame retardant composition is produced by reacting an alkali metal salt of 2,4,6-tribromophenol and cyanuric chloride in the presence of said water-insoluble polyvalent metal compound. |

1. A flame retardant composition for flammable plastic materials consisting essentially of particulate 2,4,6-tris(2,4,6-tribromophenoxy)-1,3,5-triazine containing 1 to 1000 ppm of a metal species of a water-insoluble polyvalent metal compound having a solubility in water of less than 1 g/L at 25° C., wherein said water-insoluble polyvalent metal compound is antimony trioxide, said water-insoluble polyvalent metal compound being present in said particulate 2,4,6-tris(2,4,6-tribromophenoxy)-1,3,5-triazine in a physically indiscrete form. |
