Abstract

The invention provides a macromolecule organic phosphate, a preparation method and a method for taking the macromolecule organic phosphate as a polymer material antistatic modifying agent. A polyether chain section and an acylamide group is introduced to produce an AB or / and BAB type macromolecule polymer with an organic phosphate terminal group, wherein, an A section has the acylamide group for improving the compatibility of a polymer material; B is a polyether group for improving the antistatic property and the hydrophilic performance. The macromolecule organic phosphate is mainly taken as a nylon antistatic modifying agent or an antistatic modifying agent for polyester and polyurethane. The macromolecule organic phosphate can be added when the macromolecule material is processed or canbe taken as an oil solution to treat the macromolecule material surface. The modified macromolecule material has a surface resistivity of (1x10<7> - 5x10<12>)ohm / cm <2> and a volume resistivity of (1x10<7>-5x10<12>)ohm.cm.

Description

technical field [0001] The present invention relates to a kind of macromolecular polymer, preparation method and application thereof, in particular to an acid alcohol amide polyether macromolecular phosphoric acid ester, the preparation method of the substance and the use of the macromolecular phosphoric acid ester as a macromolecular material antistatic modified. Background technique [0002] The insulating properties of polymer materials make it encounter a series of problems such as static electricity accumulation, static electricity barriers, and electromagnetic wave interference in some application places, which bring serious problems to production and life. Polyamide is widely used in engineering plastics and fiber industries, but its hygroscopicity and antistatic properties are poor, which brings inconvenience to use. The surface resistance of polyamide is generally 10 14 ~10 15 Ω, poor electrical conductivity, when in contact or friction with other substances or m...
