Problems solved by technology

Among them, halogen-free flame-retardant polyamide materials are widely used in the field of electronics and electrical appliances, but because most of the current halogen-free flame-retardant polyamide materials cannot meet the requirements of GWIT test up to 775°C, they cannot be fully used in the field of household appliances. Safety, the current connector products of household appliances generally use halogen-free flame-retardant polyamide materials or halogen-free flame-retardant PBT materials, which greatly limits the application of halogen-free flame-retardant polyamide materials
Chinese patent (CN102424722A) discloses a high glow wire plus fiber halogen-free flame-retardant nylon 66 material, although this material can meet the test requirements of GWIT, its injection molding performance is poor, and it cannot be used for injection molding products with complex structures

Abstract

The invention provides a halogen-free flame-retardant polyamide composite material as well as a preparation method and application thereof. The halogen-free flame-retardant polyamide composite material is prepared from the following components in parts by weight: short-carbon-chain aliphatic polyamide resin, a nitrogen flame retardant and methyl triallyl isocyanurate, and the nitrogen flame retardant is melamine cyanurate. According to the halogen-free flame-retardant polyamide composite material disclosed by the invention, methyl triallyl isocyanurate and melamine cyanurate are added for compounding, so that the glowing filament expression of the material is improved, the halogen-free flame-retardant effect is realized, the GWIT test at 775 DEG C is passed, the crystallization temperature and the crystallization speed of the halogen-free flame-retardant polyamide composite material can be increased, and thus, the injection molding performance of the halogen-free flame-retardant polyamide composite material is improved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, and more specifically relates to a halogen-free flame-retardant polyamide composite material and its preparation method and application. Background technique [0002] Polyamide material is a common engineering plastic, widely used in electrical and electronic, household appliances, electromechanical industry, automotive electrical and other fields. With the continuous development and progress of science and technology, various industries continue to put forward new requirements for material performance. Among them, halogen-free flame-retardant polyamide materials are widely used in the field of electronics and electrical appliances, but because most of the current halogen-free flame-retardant polyamide materials cannot meet the requirements of GWIT test up to 775°C, they cannot be fully used in the field of household appliances. Safety. At present, the connector products of household a...
