The preparation method of the invention is suitable for preparing antistatic and flame retardant resin, and the prepared antistatic and flame retardant resin is suitable for further application in making antistatic and flame retardant polyester fiber.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a resin, in particular to an antistatic and flame-resistant resin and its preparation method and application. Background technique [0002] Polyester fiber has excellent physical and chemical properties, and is low in cost. It is widely used in people's production and life, and is currently the largest synthetic fiber in the world. With the expansion of its application fields, it is necessary to meet certain antistatic requirements in some special fields, such as military, aviation, transportation, entertainment, hospital and other decorative materials, fire-fighting facilities, etc., but polyester The fiber is a kind of hydrophobic fiber, the volume resistivity under the standard condition is above 1013Ω·cm, it is easy to generate static electricity, and it is a flammable fiber. These reasons limit the application field of polyester fiber. [0003] Polyester fiber is a ...
