Problems solved by technology
[0005] Adding nano-rubber particles with core-shell structure to epoxy resin can improve the strength and flexibility of epoxy resin. However, since the nano-rubber particles with core-shell structure are difficult to disperse in epoxy resin, it may cause particles Uneven dispersion, which affects the overall resin performance
In the later stage, it is hoped to adopt the process of high-speed dispersion and grinding, but uniform dispersion cannot be achieved

Abstract
The invention provides an epoxy resin composite toughened by nano core-shell rubber particles and a preparation method thereof. The composite comprises epoxy resin, nano core-shell rubber particles, silane coupling agent and optional diluent, wherein, the epoxy resin accounts for 39%-84% of the composite weight; the nano core-shell rubber The content of the particles is 8.4% to 23.4% of the weight of the epoxy resin; the silane coupling agent is added to the composite in the form of being coated on the surface of the nano-core-shell rubber particles, and the content of the silane coupling agent is the nano-core 1% to 10% of the weight of the shell rubber particles. The nano-core-shell rubber particle toughened epoxy resin composite of the present invention has good dispersion effect and good storage stability; the composite is added as a toughening agent to the epoxy resin composition for preparing copper-clad laminates, which can The toughness of the cured epoxy resin is improved, so that a copper clad laminate with excellent flexibility can be produced.
Description
technical field [0001] The invention relates to an epoxy resin compound toughened by nano core-shell rubber particles and a preparation method thereof. Background technique [0002] Copper clad laminate (copper clad laminate, referred to as CCL) is made of wood pulp paper or glass fiber cloth as a reinforcing material, impregnated with epoxy resin, coated with copper foil on one or both sides, and formed by hot pressing. Copper-clad laminates are the basic materials of the electronics industry and are mainly used for processing and manufacturing printed circuit boards (PCBs). With the miniaturization and thinning of printed circuit boards, copper clad laminates with excellent flexibility are required. [0003] Nanomaterials are one of the most advanced research fields in today's world technology. The high-strength and high-toughness polymer-based composites can be obtained by adding nanoparticle / fiber mesh modification technology, which has always been a hot spot of common...
