Abstract

The invention relates to a halogen-free non-phosphorus flame-retarded resin composition which is composed of a constituent and a solvent; the constituent comprises the following components in parts by weight: 50-80 parts of halogen-free epoxy resin, 10-30 parts of nitrile-group resin, 5-20 parts of cyanate ester resin, 15-40 parts of curing agent and 10-100 parts of filler, wherein the constituent is dissolved in the solvent and accounts for 65wt%-75wt% of the total weight. According to the invention, the nitrile-group resin is added in the halogen-free non-phosphorus flame-retarded resin composition, so that a purpose of improving resin flame resistance, high temperature resistance and dielectric properties is realized; the halogen-free epoxy resin and the cyanate ester resin are supplemented to overcome the defects that nitrile-group resin is sufficient in toughness and machinability is poor, and water absorption of the resin is improved; and moreover, the UL-V0-grade green and environment-friendly halogen-free non-phosphorus flame-retarded resin composition with excellent toughness, machinability and water absorption is obtained.

Description

technical field [0001] The invention relates to a resin composition, in particular to a halogen-free and phosphorus-free flame-retardant resin composition and an adhesive sheet and a copper-clad laminate made of the same. Background technique [0002] With the official implementation of the WEEE and RoHS directives by the European Union in 2006, the promotion of market competition and the improvement of human environmental protection awareness, the development of halogen-free flame-retardant copper clad laminates is rapid. At present, most manufacturers have launched halogen-free flame-retardant products, and they maintain a high growth trend. At present, the mainstream route to realize halogen-free flame retardant of copper-clad laminates is to use phosphorus-based flame retardants, and mostly use phosphorus-containing epoxy resin as the main resin, and then use dicyandiamide or phenolic resin curing agent. Phosphorus-based flame retardants can make the product have a good...
