Abstract

Disclosed is a halogen-free flame-retardant resin composition. The resin composition comprises the following in parts by weight: (A) a mixture of a phenoxyphosphazene compound (A1) and a compound (A2) with a dihydrobenzoxazine ring: 45-90 parts by weight, the weight ratio of A1 to A2 being 1:25-1:2; (B) an epoxy resin with an epoxy equivalent of 500-2000: 10-45 parts by weight; (C) a phenolic resin: 10-25 parts by weight; and (D) an amine curing agent: 0.5-10 parts by weight. The pre-preg, laminated board and metal foil-coated laminated board for printed circuits prepared using the composition have the properties of high glass transition temperature (Tg), high heat resistance, low dielectric loss factor, low water absorption, low C.T.E and the like.

Description

technical field [0001] The present invention relates to a halogen-free flame-retardant resin composition and its application, specifically, the present invention relates to a halogen-free flame-retardant resin composition and prepregs, laminates and laminates for printed circuits made of it . Background technique [0002] In recent years, people's calls for environmentally friendly electronic products have become higher and higher, which has also made great progress in halogen-free technology. On the other hand, with the advent of the lead-free era, in addition to the halogen-free flame retardancy of printed circuit boards, the role of being able to cooperate with lead-free soft soldering electrodes has also become important. Therefore, laminated boards for printed circuits are also required to have higher heat resistance and reliability than before. At present, the main technologies are concentrated on phosphorus-modified epoxy resin and benzoxazine resin. It is well kno...
