Problems solved by technology

[0004] With the rapid development of electronic technology, people are increasingly seeking environmental protection, but traditional high-frequency and high-speed materials basically use halides, antimonides, etc. to achieve the purpose of flame retardancy. Not only does it generate a lot of smoke and smell bad, but it also emits highly toxic and corrosive hydrogen halide gas, which not only pollutes the environment, but also endangers human health; at present, the environmental protection compounds corresponding to phosphorus-containing and phenanthrene-type compounds DOPO or ODOPB are widely used in industry. Oxygen resin is used to realize ordinary FR-4 to achieve flame retardancy, but phosphorus-containing phenanthrene-type compounds DOPO or ODOPB still have a large water absorption rate, which has a great impact on the dielectric constant and dielectric loss tangent of high-frequency and high-speed materials

Abstract

The invention discloses a halogen-free resin composition and a method for preparing a copper-clad plate from the halogen-free resin composition. Based on the total weight part of solid ingredients of the halogen-free resin composition, the halogen-free resin composition comprises, by weight, 5 to 50 parts of reaction-type allylphenoxycyclotriphosphazene or vinylphenoxycyclotriphosphazene, 15 to 85 parts of a thermosetting resin, 1 to 35 parts of a crosslinking curing agent, 0 to 5 parts of a crosslinking curing accelerator and 0 to 100 parts of a filling material. Through introduction of reaction-type allylphenoxycyclotriphosphazene or vinylphenoxycyclotriphosphazene having very low water absorbency into the thermosetting resin, the halogen-free resin composition can satisfy halogen-free flame-retardation requirements, improve system electrical properties, and realize non-halogenation of a high-frequency high-speed substrate material. The copper-clad plate prepared from the halogen-free resin composition satisfies halogen-free requirements, has excellent heat resistance and moisture resistance and has a low dielectric loss.
