Abstract

The invention discloses a lanthanide-series material containing nanometer polyester imide film and a preparation method thereof. The lanthanide-series material containing nanometer polyester imide film is prepared from the following two components in parts by weight: 100-120 parts of a polyester imide solution and 0.1-5 parts of a pretreated nanoscale lanthanide-series material, wherein the polyester imide solution comprises the following components in parts by weight: 20-35 parts of polyester imide resin and 20-60 parts of an organic solvent; the pretreated nanoscale lanthanide-series material is obtained by pretreating a nanoscale lanthanide-series element, a coupling agent and a surfactant according to a weight ratio of 10: (2-6): (0.2-0.5); the nanoscale lanthanide-series material can be nanoscale lanthanum, nanoscale cerium, nanoscale praseodymium, nanoscale neodymium, nanoscale promethium or the like. The nanometer polyester imide film has the advantages of excellent optical properties, stable chemical properties, mechanical properties and high temperature resistance, strong self-lubricating performance and long service life, and can be widely applied to the glazeed wire industry.

Description

technical field [0001] The invention belongs to the field of film preparation, in particular to a nanometer polyesterimide film containing lanthanide material and a preparation method thereof. Background technique [0002] High temperature resistant polyesterimide is currently mainly used in the enameled wire industry. At present, the existing high-temperature-resistant polyesterimide is widely used in the market, but the problem is that the mechanical properties need to be improved, the optical properties need to be improved, and the high-temperature resistance needs to be further improved; in order to meet the needs of the market, it is urgent to develop new types of strong Self-lubricating, high temperature resistant and long life polyesterimide film. Contents of the invention [0003] The object of the present invention is to provide a kind of nano-polyesterimide film containing lanthanide element material with excellent mechanical properties, stable chemical properti...
