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 phenoxy cyclotriphosphazene active ester, halogen free resin composition and application thereof. The phenoxy cyclotriphosphazene active ester contains the substance having the following structure shown in the description in mol ratio of at least 65%. The halogen free resin composition comprises, by weight, 5 to 50 parts of phenoxy cyclotriphosphazene active ester, 15 to 85 pars of thermosetting resin, 1 to 35 parts of curing agent, 0 to 5 parts of curing accelerator and 0 to 100 parts of inorganic filling material. The phenoxy cyclotriphosphazene active ester, halogen free resin composition and application thereof, by generating no hydroxy in the reaction between active ester and thermosetting resin such as epoxy resin and so on through introducing phenoxy cyclotriphosphazene active ester into thermosetting resin, can meet requirements of halogen free and flame retardation, improve the electrical property of the system (reduce and stabilize Dk and Df), and enable the substrate material with high frequency and high speed to be halogen free.
