Abstract

The invention relates to the technical field of macromolecular composite materials, and discloses a red phosphorus flame retardant enhanced PA66 (nylon resin) and POK (polyketone) alloy material and a preparation method thereof. The red phosphorus flame retardant enhanced PA66 and POK alloy material is prepared from nylon resin, polyketone resin, red phosphorus master batch, a synergist, an antioxidant, a lubricating agent and glass fibers. The material is mainly prepared from the following components in percentage by weight: 5 to 50 percent of PA66, 15 to 25 percent of POK, 10 to 25 percent of the red phosphorus master batch, 20 to 35 percent of the glass fibers, 5 to 10 percent of the synergist, 0.2 to 0.5 percent of the antioxidant and 0.1 to 0.5 percent of the lubricating agent. The material is excellent in electrical property; the ignition temperature of a combustible heat wire of the material can be up to 850 DEG C; the material has high CTI value which is 600 V. The material is stable in processing, has excellent mechanical property and can be widely applied to the electrical and electronic industry.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a red phosphorus flame-retardant reinforced PA66 and POK alloy material and a preparation method thereof. Background technique [0002] As a thermoplastic polymer, PA66 (nylon resin) has significant mechanical properties, such as high strength, self-lubrication, and excellent chemical resistance. It is mainly used in electronic and electrical components, automobiles and electrical tools, etc. field. At present, flame-retardant PA66 materials used in the field of electronic appliances are mainly halogen-based flame-retardant materials, but such materials contain halogen, and their application in specific fields is limited, such as circuit breakers. At the same time, PA66 is easy to absorb water, which will affect the inherent electrical properties of the material and cause dimensional deviation. [0003] POK, Chinese name polyketone. It is a new green and en...
