摘要： The present invention provides a composite flame retardant which can be produced without using any toxic metal such as antimony trioxide or any halogen such as bromine and chlorine and can exhibit excellent flame retardancy compared with magnesium hydroxide when added in a smaller amount; and a flame retardant resin composition having excellent flame retardancy and excellent physical properties. The present invention relates to a flame retardant including: (A) 100 parts by mass of a reaction product of piperazine with one phosphorus compound selected from phosphoric acid, pyrophosphoric acid, and polyphosphoric acid; (B) 10 to 1000 parts by mass of a reaction product of melamine with a polyacid selected from cyanuric acid, phosphoric acid, pyrophosphoric acid, and polyphosphoric acid; and (C) 0.1 to 100 parts by mass of a reaction product of calcium or magnesium with silicic acid.

摘要： The present disclosure provides powdery (poly)piperazine pyrophosphate that is not accompanied by difficult-to-remove byproducts and is not tinged with a color that would adversely affect the coloring of the molded article. The present disclosure also provides a method of producing such powdery (poly)piperazine pyrophosphate in an efficient manner and with a high yield. The present disclosure relates to a method for providing powdery (poly)piperazine pyrophosphate, which includes the step of dehydration condensation of piperazine diphosphate to prepare (poly)piperazine pyrophosphate. The step is performed under an inert gas atmosphere, and thereby powdery (poly)piperazine pyrophosphate having a whiteness of 80 to 100 as a W value, and a yellowness of 0 to 5 as a YI value is produced.

摘要翻译： 本公开内容提供粉末状（聚）哌嗪焦磷酸盐，其不伴有难以除去的副产物，并且不会对对模制品的着色产生不利影响的颜色混合。 本公开还提供了以有效的方式和高产率生产这种粉末状（多）哌嗪焦磷酸盐的方法。 本发明涉及提供粉末状（多）哌嗪焦磷酸盐的方法，该方法包括使哌嗪二磷酸酯脱水缩合制备（聚）哌嗪焦磷酸盐的步骤。 该步骤在惰性气体气氛下进行，由此产生作为W值的白度为80至100的白色粉末状（聚）哌嗪焦磷酸盐，并且产生作为YI值的0至5的黄色度。
