Abstract

The invention discloses a polyphosphate compound containing a phenolphthalein derivative and a high polymer material applying the same. The polyphosphate compound containing the phenolphthalein derivative has high thermal stability and can serve as a viscosity reducer and a fire retardant; and when the polyphosphate compound containing the phenolphthalein derivative is applied to the high polymer material, processing viscosity of engineering plastic can be greatly reduced, thermal properties of the macromolecular material are also better reserved, and a good fire retardant effect is also realized.

Description

technical field [0001] The application relates to a compound with flame retardancy and a polymer material using it, belonging to the field of polymer materials. Background technique [0002] Flame-retardant polymer materials, especially glass fiber reinforced polyamide, polyester PBT, high-temperature nylon and polycarbonate, are widely used in the manufacture of electrical sockets, connectors, relays and other small electronic components in the electronics and electrical industry. Traditionally, the flame retardancy of polymer materials is realized by brominated flame retardants, but brominated flame retardants can produce strong carcinogenic dioxins when burned, and the hydrogen bromide produced at the same time can cause secondary pollution, so In recent years, the use of brominated flame retardants has been gradually restricted, and the flame retardant of polymer materials has turned to halogen-free flame retardants. Among them, bisphosphate or oligophosphate flame reta...
