Problems solved by technology

However, epoxy resin contains a large number of epoxy groups. After curing, the crosslinking density is large, the texture is brittle, and the weather resistance and moisture resistance are poor. Therefore, it is difficult to meet the requirements of engineering technology, and its application is subject to certain restrictions.

Abstract

The invention relates to an electronic heat-resisting composite material. A nitrogen compound and ceramic powder are mixed for 2 h, and then N-formyl morpholine and sodium iodide are added and mixed for 1.5 h to obtain a mixture; an amine compound and a diisoamyl dicyclopentadiene oxide are added into the mixture in sequence to be stirred at the temperature of 95 DEG C for 2 h; then an acrylate-styrene copolymer is added to be stirred at the temperature of 120 DEG C for 1 h; then, 2,6-bi(4-aminophenoxy)benzonitrile is added to be stirred at the temperature of 180 DEG C for 2 min to obtain a compound; the compound is placed into a mold, and mold pressing is performed to obtain an electronic heat-resisting composite material. The preparation method is wide in raw material source, the preparation process is simple and controllable, 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 an electronic heat-resistant composite material. Background technique [0002] 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 and other fields. According to the different curing methods of epoxy resin, epoxy resin coatings can be divided into normal temperature curing type, natural drying type, drying type and cationic electrophoretic epoxy coating. However, epoxy resin contains a large number of epoxy groups, and after curing, it has high crosslinking density, brittle quality, poor weather resistance and moisture resistance, so it is difficult to meet the requirements of engineering technology, and its application is limited....
