る。2. Description of the Related Art Polyamide resins have excellent mechanical properties, molding processability, and chemical resistance, and are used in various fields such as automobile parts, electric / electronic parts, and mechanical parts. Particularly in electric / electronic parts, there is a strong demand for solder resistance and flame resistance. High melting point resins such as aromatic polyamide, 4,6-nylon and polyphenylene sulfide have been developed in order to obtain a molded article having excellent solder resistance.

いない。However, with respect to 4,6-nylon, the water absorbency of the resin is remarkable and the dimensional stability of the molded product cannot be obtained. Also for polyphenylene sulfide,
There are many problems in moldability, such as a lot of burrs on the molded product and the mold temperature must be set to a high temperature. Aromatic polyamides are superior in moldability to other resins, but none are known that can sufficiently meet market demands.

ない。On the other hand, a method of adding a considerable amount of a flame retardant is widely used to make a resin flame-retardant. In particular, a combination of a halogen compound and an antimony compound is excellent in flame retardant effect and raw material cost, and therefore many compositions are already known. Similar compositions are known for high-melting-point resins, but the stability of the composition is not sufficient, so a flame-retardant resin composition with sufficient appearance and molding safety during molding and pellet production Things have not been obtained.

に優れた組成物を得ることができる。In order to solve the above problems, the present invention comprises copolymerizing terephthalic acid or a mixture of terephthalic acid and isophthalic acid and a mixture of hexamethylenediamine and 2-methylpentamethylenediamine. A specific flame retardant, flame retardant aid, and the like were added to the high-melting aromatic polyamide copolymer. Since the above-mentioned copolymer is excellent in heat resistance and mechanical strength and has a melting point in the range of 280 to 330 ° C., the resin temperature at the time of production can be set so as not to cause decomposition and deterioration of the flame retardant. It is possible to obtain a composition having excellent moldability and work safety.

The amount of the flame retardant added is 10 to 100 parts by weight, preferably 20 to 50 parts by weight. The amount of the flame retardant added is 1
The amount is set to 0 to 100 parts by weight because if it is less than 10 parts by weight, a problem of flame retardancy occurs, and if it is added in an amount of more than 100 parts by weight, a problem occurs in mechanical strength.

0 parts by weight. The amount of the flame retardant aid added is 0.5 to 40.
The reason why the amount is 0.5 part by weight is that if it is less than 0.5 part by weight, the flame retardant effect is not exhibited, and if it is more than 20 parts by weight, mechanical strength becomes a problem. Antimony oxide is, for example, antimony trioxide, antimony tetraoxide, antimony pentoxide, or the like. Antimony pentoxide or sodium antimonate is particularly suitable as the flame retardant aid of the present invention.
