Document Type and Number:
WIPO Patent Application WO/2021/128630
Kind Code:
A1
Abstract:
Provided are a thermosetting epoxy resin composition and a prepreg, laminated board and printed circuit board using the thermosetting epoxy resin composition. The thermosetting epoxy resin composition comprises the following components in parts by weight: 2-10 parts of a phosphorus-containing anhydride, 5-40 parts of a phosphorus-free anhydride, 5-45 parts of an epoxy resin, 40-70 parts of a filler, and 0-15 parts of a phosphorus-containing flame retardant, with the total part by weight of all these components being 100 parts, wherein the phosphorus-containing anhydride has a structure as represented by formula I or II, and the epoxy resin is selected from one of or a combination of at least two of a bisphenol A epoxy resin, a bisphenol F epoxy resin and a biphenyl epoxy resin. The thermosetting epoxy resin composition also has good heat resistance, discoloration resistance and dimensional stability after curing while ensuring V-0 grade flame resistance, and can be used for the preparation of printed circuit board substrates in the field of LEDs.
