Abstract

The invention relates to a high-performance MCA flame-retardant nylon material and a preparation method thereof. The high-performance MCA flame-retardant nylon material is prepared from the followingcomponents: PA6 resin, an MCA flame retardant, chopped glass fibers, an antioxidant and a lubricant. According to the flame-retardant nylon material obtained through a special extrusion process, the reserved length of the chopped glass fibers is in bimodal distribution, so that the flame-retardant nylon material has excellent glowing filament characteristics, has better mechanical properties and heat resistance, and can be applied to the fields of low-voltage electrical appliances, electronic appliances, connectors and the like.

Description

technical field [0001] The invention belongs to the field of halogen-free flame-retardant nylon materials, in particular to a high-performance MCA flame-retardant nylon material and a preparation method thereof. Background technique [0002] Polyamide resin has excellent mechanical properties, barrier properties, heat resistance, wear resistance, chemical corrosion resistance and other comprehensive properties, and is widely used in machinery manufacturing, electric tools, electronic appliances, transportation and other fields. Melamine cyanurate (MCA) has a high nitrogen content and will generate NH when it is thermally decomposed 3 、H 2 O, N 2 , CO 2 、H 2 Non-combustible gases such as NCN have the functions of absorbing heat, cooling down, and diluting the concentration of flammable gases and oxygen. They are often used as flame-retardant modifiers for thermoplastic resins, especially for flame-retardant nylon systems. At the same time, because the halogen-free flame ...
