Abstract

The invention discloses a high glow-wire and fiber halogen-free flame-retardant nylon 66 material and a preparation method thereof. The high glow-wire and fiber halogen-free flame-retardant nylon 66 material comprises the following components in parts by weight: 100 parts of PA 66 resin, 12-24 parts of halogen-free fire retardant, 0.15-0.6 parts of nucleating agent, 0.3-0.6 parts of antioxidant, 0.45-1.2 parts of lubricant and 25-30 parts of glass fibre. The high glow-wire and high-performance fiber halogen-free flame-retardant nylon 66 material provided by the invention is excellent in mechanical property, halogen-free, environment friendly and flame-retardant, and the glow-wire does not inflame at 750 DEG C within 30s; and the used raw materials are wide in source and low in cost, therefore, the high glow-wire and fiber halogen-free flame-retardant nylon 66 material is very suitable for industrial production. The prepared high glow-wire and fiber halogen-free flame-retardant nylon 66 material and the preparation method thereof can be widely applied to the field of electronic appliances such as a breaker shell, a motor shell, a connector, a light touch switch and the like.

Description

technical field

[0001] The invention relates to the field of polymer materials, in particular to a high-glow wire, high-performance fiber-added, halogen-free, environment-friendly and flame-retardant nylon 66 material and a preparation method thereof. Background technique

[0002] Nylon 66 (PA66) is the earliest synthetic fiber and the most important product among polyamides. It can be used as both fiber and engineering plastic. PA66 is widely used in industry, clothing and engineering plastics because of its good comprehensive properties, such as high strength, good rigidity, impact resistance, oil and chemical resistance, wear resistance and self-lubricating properties, etc., and the raw materials are easily available and low cost. and other fields. The nylon material modified by glass fiber reinforcement and flame retardancy has higher mechanical strength and better flame retardancy, and can replace some metals and other thermoplastic engineering plastics in electronic a...
