〈産業上の利用分野〉
本発明は、耐ブリード性に優れた難燃性組成物に関する

しかしこれは、ハロゲン含有化合物であり燃焼時に有毒
なハロゲンガスを発生し好ましくない。However, this is a halogen-containing compound and generates toxic halogen gas when burned, which is undesirable.

。There are also flame-retardant resins made by adding compounds having a large number of hydroxyl groups, such as pentaerythritol or tris(2-hydroxyethyl) incyanate, to polyolefin resins as polyhydric alcohols. However, compounds having a large number of hydroxyl groups are generally easily soluble in water and are not preferred.

ド現象が現われて好ましくない。A low-molecular salt of a phosphate compound with a spiro ring and melamine is added to polyolefin resin to impart flame retardancy. (Japanese Patent Publication No. Sho 63-19518) <Problems to be Solved by the Invention> However, conventional flame retardants are low molecular salts and therefore have poor water resistance due to their chemical structure. It is true that it is insoluble or poorly soluble in water at room temperature, but this insolubility and poorly soluble property is not maintained in water at 50°C or higher. This is undesirable because when this flame retardant is added to an olefin resin, a bleed phenomenon occurs, in which powder is blown onto the resin surface, similar to when a polyhydric alcohol is added.
従来技術にあるように常温の水において不溶性であるだ
けでは、高温高湿の環境下にその難燃剤を添加した樹脂
をさらすまでもなく、加工時に樹脂上に難燃剤が浮きだ
し、外観上、好ましくない。If the resin is insoluble in water at room temperature as in the conventional technology, there is no need to expose the resin containing the flame retardant to a high-temperature, high-humidity environment, and the flame retardant will float on the resin during processing, resulting in a poor appearance. Undesirable.

リード現象が起こらない難燃性組成物を目的とする。The object of the present invention is to provide a flame retardant composition that does not cause bleeding on the resin surface even when exposed to a high temperature and high humidity environment.

すぐれていた。<Effects of the Invention> By using a heterocyclic diamine, a phosphate flame-retardant polymer having a spiro ring, and condensed ammonium phosphate in combination, the flame-retardant composition of the present invention can be used in combination with a flame-retardant composition having a spiro ring than that of the prior art. It was possible to suppress the occurrence of bleed, which could not be avoided when a low-molecular salt of a phosphate compound and melamine was added. Furthermore, the flame retardant U L-94 and oxygen index as a flame retardant polymer composition were excellent.
