Problems solved by technology

[0007] In addition, according to studies by the inventors of the present invention, it has been found that when electrical and electronic components are manufactured using a resin composition containing a sulfur-containing melamine-based flame retardant such as melamine sulfate, due to the heat generated during energization, etc., the Produce sulfate ions, sulfur dioxide, hydrogen sulfide and other metal corrosive gases, corrode metal contacts and terminals, resulting in poor conduction and other problems

Embodiment

[0118] Hereinafter, although this invention is demonstrated based on an Example, this invention is not limited to these Examples at all. In addition, each component used in the following Example is specifically as follows. In addition, the evaluation of the polyamide resin composition which consists of these components was performed by the method described below.

[0119] [ingredients used in examples]

[0120] Polyamide resin (A)

[0121] (A-1) Polyamide 6: manufactured by Mitsubishi Engineering-Plastics Co., Ltd., "trade name: Novamid (registered trademark) 1010J", viscosity number 118ml / g (according to ISO307 standard, at a temperature of 25°C, in 96% by weight sulfuric acid, The value measured at a polyamide resin concentration of 0.5% by weight), and a melting point of 224°C.

[0122] (A-2) Polyamide 6 / 66 copolymer: manufactured by Mitsubishi Engineering-Plastics Co., Ltd., "Novamid (registered trademark) 2010J", viscosity number 118 ml / g (measured by the same method...

reference example 1

[0145] 100 parts by weight of polypropylene (manufactured by Mitsubishi Chemical Corporation, MVR 1 cm 3 / 10 minutes), 2 parts by weight of maleic anhydride (manufactured by Mitsubishi Chemical Corporation), and 3.5 parts by weight of benzoyl peroxide (manufactured by NOF Corporation, "trade name: Nyper BMT-K-40") were mixed with a super mixer Mix for 1 minute to obtain a mixture. Next, the obtained mixture was extruded with a twin-screw extruder (manufactured by Japan Steel Works, "Model: TEX30HCT", barrel inner diameter 30mm, L / D=42) at a barrel set temperature of 230°C and a screw speed of 300rpm 1. Melt-kneading was carried out under the condition of a discharge rate of 15 kg / hour, extruded into a thread shape through a die, and then cut by a cutting machine to obtain pellets of modified propylene polymer-1.

Abstract

Disclosed is a flame-retardant polyamide resin composition excellent in all of flame retardation, glow-wire characteristic, tracking resistance and mechanical strength, and also in anti-corrosive performance for metals, and suitably be applied to electric / electronic components having metal contacts or metal terminals, such as connectors and so forth. A flame-retardant polyamide resin composition comprising, per 100 parts by weight of polyamide resin (A), 10 to 60 parts by weight of a salt (B) of an aminotriazine compound and at least one compound selected from the group consisting of sulfuric acid, pyrosulfuric acid and organosulfonic acid, and at least one compound (C) selected from the group consisting of hindered phenol-base compound, hydrotalcite and hydroxide of alkaline earth metal, wherein the ratio of comprising (C) / (B) by weight of the component (C) and the component (B) is 0.0005 to 0.2.

Description

technical field [0001] The present invention relates to a flame-retardant polyamide resin composition. Specifically, it relates to a flame-retardant polyamide resin composition which is excellent in arc tracking resistance and glow wire characteristic as one of electrical safety of electric parts and electronic parts, and is resistant to metal corrosion It is also excellent in performance and is suitable for electric and electronic parts with metal contacts and metal terminals. Background technique [0002] Polyamide resins have been used in automotive parts, mechanical parts, electrical and electronic parts, and the like due to their excellent mechanical strength, heat resistance, and the like. Especially in recent years, in the use of electrical and electronic components such as connectors and plugs with metal terminals, switches and circuit breakers with metal contacts, the level of flame retardancy requirements has gradually increased, and the requirements are higher th...
