Problems solved by technology

[0003] Epoxy resin has excellent adhesion, thermal stability and excellent chemical resistance. As a resin matrix for adhesives, coatings and composite materials, it is widely used in water conservancy, transportation, machinery, electronics, home appliances, automobiles and aerospace However, epoxy resin contains a large number of epoxy groups, and after curing, it has high crosslinking density, brittle texture, poor weather resistance and heat and humidity resistance, so it is difficult to meet the requirements of engineering technology, and its application is subject to certain restrictions.

Abstract

The invention relates to a heat-resistant electronic membrane and a preparation method thereof. The preparation method includes the steps that a mixture of silicon dioxide, ytterbium fluoride, magnesium oxide, calcium carbonate, zirconia and zirconia is subjected to ball milling and calcination, and filler is obtained; amine compound and the filler are mixed for one hour, then N-formyl morpholine, a nitrogen compound and sodium iodide are added and mixed for two hours, and a mixture is obtained; bi-isoprene bicyclo oxide and 2,6-bi-(4-aminophenoxy) cyanobenzene are sequentially added to the mixture and stirred for 5 minutes t the temperature of 170 DEG C, and a compound is obtained; the compound is added to an extruder; then, a polyimide film with the surface subjected to corona treatment passes through the extruder at the speed of 1 m / min, the compound is applied to the polyimide film obtained after treatment through an extrusion die head, and the composite polyimide film is obtained; the heat-resistant electronic membrane is obtained after the composite polyimide film is subjected to forming treatment. The preparation method is wide in raw material source, simple and controllable in preparation process, only conventional operation is needed, and industrialization is facilitated.

Description

technical field [0001] The invention belongs to the technical field of electronic materials, and in particular relates to a heat-resistant electronic film and a preparation method thereof. Background technique [0002] Polyimide materials are widely used in wires, cables, petroleum industry, aerospace and other fields due to their excellent high / low temperature resistance, radiation resistance, weather resistance, etc. and excellent electrical properties. In particular, polyimide film is widely used in the connection and support of electronic products due to its good mechanical properties, heat resistance and insulation properties. Due to its own defects, pure polyimide film limits its large-scale application. In order to further improve the application performance of polyimide film, composite film technology is widely used. Composite materials are important basic materials for high-tech fields such as information technology, biotechnology, and energy technology, and for na...
