Abstract

The invention discloses a nanometer polyamide imide film containing inorganic oxide. The nanometer polyamide imide film containing the inorganic oxide is prepared from the following components in parts by weight: 100 to 120 parts of polyamide imide solution and 0.5 to 10 parts of pretreated nanometer inorganic oxide material. The thickness of the nanometer polyamide imide film containing the inorganic oxide is 10 to 100nm; the polyamide imide solution is prepared from the following components in parts by weight: 20 to 35 parts of polyamide imide resin and 20 to 60 parts of organic solvent. The pretreated nanometer inorganic oxide material is obtained by pretreating nano inorganic oxide, a coupling agent and a surfactant according to the weight ratio of 10:(2 to 6):(0.2 to 0.5). The nanometer polyamide imide film disclosed by the invention has the advantages of excellent mechanical property, stable chemical properties, high temperature resistance, high self-lubricating property and long service life, and can be widely applied in the enamelled wire industry.

Description

technical field [0001] The invention relates to the technical field of thin films, and more specifically relates to a nanometer polyamide-imide thin film containing inorganic oxides and a preparation method thereof. Background technique [0002] High temperature resistant polyamide-imide is currently mainly used in the enameled wire industry.
