Abstract

The invention provides a halogen-free flame-retardant resin and a preparation method thereof. The halogen-free flame-retardant resin comprises the following components in parts by weight: 100 parts ofpolyamide 56, 5-20 parts of an organic halogen-free flame retardant, 5-40 parts of glass fibers, 0.05-0.5 part of a lubricant and 0.05-0.5 part of an antioxidant. The halogen-free flame-retardant resin disclosed by the invention adopts renewable substances as main raw materials, is environment-friendly, and further has good flame-retardant property and good mechanical property.

Description

technical field [0001] The invention relates to a resin, in particular to a halogen-free flame-retardant resin and a preparation method thereof, and belongs to the technical field of halogen-free flame-retardant polymers. Background technique [0002] Due to their excellent mechanical and formability properties, polyamides are often used for sheathing and insulation of electrical cables, as well as for components in electrical and electronic equipment and many other applications. The flame-retardant modified polyamide has good flame retardancy, is a self-extinguishing material, and has good electrical insulation properties. However, these flame-retardant polymers are only flame-retardant, and will eventually form ashes when exposed to open flames or high-temperature combustion. In the application of electronic appliances and wires, they will cause short circuits or personal injury, causing secondary damage. Contents of the invention [0003] The invention provides a halog...
