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 influence on the dielectric constant and dielectric loss tangent of high-frequency and high-speed materials

Abstract

The invention discloses a phenoxycyclotriphosphazene active ester, a halogen-free resin composition and applications thereof. The phenoxycyclotriphosphazene active ester contains at least 65% by molar ratio of substances having the following structural formula. The halogen-free resin composition comprises in parts by weight: 5-50 parts by weight of phenoxycyclotriphosphazene active ester, 15-85 parts by weight of thermosetting resin, 1-35 parts by weight of curing agent, 0-5 parts by weight Parts of curing accelerator and 0-100 parts of inorganic filler. The present invention introduces phenoxycyclotriphosphazene active ester into the thermosetting resin, utilizes the reaction of the active ester with thermosetting resins such as epoxy resins without generating hydroxyl groups, can not only meet the requirements of halogen-free flame retardancy, but also improve the electrical properties of the system (reduce , stable Dk and Df), making it possible for high-frequency high-speed substrate materials to be halogen-free.
