優れており、多く実用に供されてきた。[Prior Art] Since a high degree of flame retardancy is required in the electronic and electrical fields, flame-retardant resins are usually used. In particular, flame-retardant nylon 66 is prized for its good moldability and high heat resistance. One method for making nylon 66 flame retardant is to add a halogen flame retardant. Conventionally, a cyclooctadiene adduct of hexachlorocyclopentadiene has been used as a flame retardant, but there was a problem in that it partially thermally decomposed during molding, leading to discoloration of molded products and deterioration of mechanical properties. Recently, polymer type brominated flame retardants have been developed and proposed to improve these drawbacks. In particular, nylon 66 is made of brominated polystyrene (JP-A-51-47034, JP-A-5
1-47044, JP-A-53-9656)
Or brominated polyphenylene oxide (Japanese Patent Publication No. 56-6
100, Japanese Patent Publication No. 60-41093) are suitable. Among these two types, the former is particularly superior to the latter in terms of discoloration due to thermal deterioration during molding and deterioration of mechanical properties, and has been put to practical use in many cases.

Polyamides obtained by condensation polymerization of aliphatic aminocarboxylic acids, aliphatic polyamides obtained by ring-opening polymerization of lactams, copolymers thereof, polymer blends, or weld strength of the thin-walled portion referred to herein in the present invention are not reduced. A range of amounts of polyamides other than those mentioned above, such as aromatic dicarboxylic acids, aromatic diamines, alicyclic dicarboxylic acids, alicyclic diamines, etc., may be copolymerized or polymer blended. Specific examples include the following, but are not limited thereto. For example, nylon 66, nylon 46. Nylon 610. Nylon 612. Nylon 6, nylon 11, nylon 12. There are also copolymers, polymer blends, or copolymers or polymer blends of these with hexamethylene terephthalamide, hexamethylene isophthalamide, cyclohexyl adipamide, etc. Among these nylons, the effects of the present invention tend to be particularly noticeable in nylon 66, nylon 6, and copolymers or polymer blends thereof. Nylon 66, nylon 46. Copolymers and polymer blends containing these as main components have high heat resistance and are therefore important for solder resistance, particularly as materials for surface mounting.

するため好ましくない。It is effective to add, in addition to the above flame retardant, a metal oxide that exhibits a flame retardant effect. By doing so, the amount of flame retardant added can be reduced. Examples of metal oxides that can be used include antimony compounds such as antimony trioxide and sodium antimonate, zinc oxide, iron oxide, tin oxide, calcium oxide, magnesium oxide, aluminum oxide, copper oxide, and titanium oxide. Zinc borate is also known as an effective compound. The amount of metal oxide added is about 0 to 15% by weight, preferably about 3 to 9% by weight. If too much is added, the mechanical strength of the entire composition will decrease, which is not preferable.

量部〜３０重量部である。It is desirable to fortify the compositions of this invention with reinforcing agents. This is because, as electronic and electrical components become thinner, unreinforced polyamide lacks rigidity. Additionally, reinforced materials have less dimensional change due to water absorption and tend to have higher thermal deformation temperatures. As the reinforcing agent, well-known reinforcing agents and fillers for nylon can be used. For example, glass fiber, carbon fiber, van-shaped reinforcement such as potassium titanate, wollastonite, kaolin, calcined kaolin, talc, mica,
There are inorganic fillers such as graphite and glass beads. Glass fiber reinforcement is particularly preferred.The amount of these reinforcing agents added is 0 to 100 parts by weight, preferably 5 to 45 parts by weight, per 100 parts by weight of the composition consisting of polyamide, brominated polyphenylene oxide, and flame retardant aid. More preferably, it is 15 parts by weight to 30 parts by weight.
補強剤が少なすぎるとその効果が不十分であるし、多す
ぎると成形加工時の流動性が悪くなり、成形品の表面肌
があれたり、ショートショットになる。If the reinforcing agent is too small, its effect will be insufficient, and if it is too large, the fluidity during molding will be poor, resulting in rough surface texture and short shots of the molded product.

For this purpose, it is effective to use a twin-screw press ratio machine. Efforts such as melt-kneading polyamide and flame retardant, and in some cases flame retardant aid in a twin-screw press ratio machine, and side-feeding the reinforcing agent, have good effects on physical properties.
