Problems solved by technology

However, the use of bromine-based halogen compounds, combined with flame-retardant additives such as antimony trioxide, can make the flame-retardant properties of epoxy resin laminates meet the requirements of, for example, UL94V-0 grades, but containing Bromine-based halogen compounds will cause bromine to decompose when heated, and their heat resistance will deteriorate under long-term use, and flame retardants containing halogen components or antimony trioxide will produce dioxin and oxocene under high-temperature combustion. Compounds that are threatening to human health will undoubtedly bring serious harm to human beings

Abstract

The phosphorus-containing epoxy resin composition of the present invention comprises: (A) phosphorus-containing epoxy resin, (B) curing agent, (C) one or more epoxy resins and (D) inorganic filler material; Wherein with component ( Based on the total weight of A), (B) and (C), the hardener of the component (B) includes 15 to 30% by weight of a benzoxazine compound, and 2.5 to 9% by weight of styrene-maleic di anhydride copolymer. The phosphorus-containing epoxy resin composition of the present invention uses a specific content of benzoxazine compound and styrene-maleic anhydride copolymer as a hardener, not only has good flame retardancy and heat resistance, but also has a high dimension Stability, low moisture absorption and excellent electrical properties are suitable for making prepregs, adhesive sheets, semiconductor packaging materials, copper foil laminates, printed circuit boards, and semiconductor packaging substrates.

Description

technical field [0001] The present invention relates to a phosphorus-containing epoxy resin composition, in particular to a phosphorus-containing epoxy resin composition using a benzoxazine compound as a hardener. Background technique [0002] Due to the characteristics of easy processing, high safety, excellent mechanical properties and chemical properties, epoxy resin is widely used in fields such as coating, electrical insulation, civil engineering and construction materials, adhesives and laminated products. Among them, the laminated board made of epoxy resin has strong adhesion to reinforcing materials such as glass fiber cloth, no volatile matter is produced during hardening, and the forming shrinkage is small, so the laminated board obtained has a wide range of applications. The advantages of excellent mechanical strength, good electrical insulation, and good chemical resistance have greatly improved the reliability of laminated boards, making epoxy resin laminated bo...
