Abstract
This scheme discloses an epoxy resin composition, a prepreg and a laminate. In terms of mass fractions, the composition includes the following components: 10 to 70 parts of isocyanate silicone modified epoxy resin, 10 to 40 parts of functional resin, 10 to 40 parts of curing agent, 10 to 60 parts of filler, 0.1 to 3 parts of coupling agent, and 0.1 to 2 parts of curing accelerator. The isocyanate silicone modified epoxy resin contains epoxy groups, siloxy groups and isocyanate groups on the molecular chain segments at the same time. Compared with ordinary epoxy resins, it has better yellowing resistance, weather resistance and chemical stability, and has better bonding performance than ordinary silicon-modified epoxy resins, so that the composition has significant advantages over traditional materials in terms of bonding performance, yellowing resistance and weather resistance. This innovation not only broadens the application scope of epoxy resins, but also provides more reliable and efficient solutions for fields such as LED lighting and integrated circuit packaging.
