Abstract

The invention relates to a method for preparing ethylene rhodanate-epoxy-POSS hybrid resin, which is mainly applied to advanced electronic packaging substrate materials. Heat resistance and dielectric property are hard to be enhanced significantly only by molecular design of epoxide resin at present. Ethylene rhodanate modified epoxy has better heat resistance but unobvious improvement of dielectric property; and dent resistance is greatly affected and moisture absorption is relatively high. The invention adopts unique functionalized hollow polyhedral oligmeric silsesquioxane nanometer oligomer modified epoxy-ethylene rhodanate, thus obtaining the advanced electronic packaging substrate resin with good heat resistance and low dielectric property; the solidified hybrid material has good net-working structure; and the polyhedral oligmeric silsesquioxane is dispersed in the resin substrate at molecular level. The mechanical property of the resin substrate is significantly improved; moreover, the heat resistance, the dielectric property and the moisture absorption property are good. The hybrid resin can be used for a long time at the high temperature of 200 DEG C.

Description

technical field [0001] The invention relates to a preparation method of a cyanate ester-epoxy resin nanometer hybrid material, which belongs to the field of organic polymer materials. Background technique [0002] With the development of social informatization, high-speed information processing and information dissemination, and miniaturization of equipment, it is urgent to provide a printed circuit composite material with high heat resistance and ultra-low dielectric properties. Epoxy resin has become a widely used printed circuit composite material due to its good processing performance, low price, sufficient supply, and excellent comprehensive performance. However, in recent years, in order to meet the demand for advanced composite materials in the field of ultra-thin micro-nano printed circuit substrates, the heat resistance and dielectric properties of epoxy resins have been further improved, especially the dielectric constant and dielectric loss in a wide frequency ran...
