Problems solved by technology

Due to the low polarity of polyphenylene ether resin, the compatibility with other resins in the resin composition is poor, which will affect the appearance of prepreg; in addition, the impregnation of polyphenylene ether resin and glass fiber cloth is not ideal , it is easy to gather into a film on the surface of the glass cloth, which will also affect the appearance of the prepreg, and then have an adverse effect on the dielectric properties of the product
[0004] The patent with publication number CN1556830 proposes a method of functionalizing polyphenylene ether, that is, reacting polyphenylene ether with bisphenol A epoxy resin under the action of an amine catalyst, and obtaining two end groups with two rings respectively. The polyphenylene ether / epoxy resin prepolymer of oxygen group, this method has improved the above-mentioned application problem of polyphenylene ether to a certain extent, but the bisphenol A type epoxy resin that introduces is to resin molecule The dielectric properties of the material are adversely affected - increasing its Dk / Df

Abstract

The present invention provides a resin composition, and a prepreg and a laminated board using the same. The resin composition comprises an epoxy resin-modified polyphenylene oxide resin prepolymer and a benzoxazine resin. The present invention applies the epoxy resin-modified polyphenylene oxide resin prepolymer in a resin composition for a printed circuit board, improving a dielectric performance of a copper clad laminate and increasing a glass fabric impregnation of the resin composition comprising the epoxy resin-modified polyphenylene oxide resin prepolymer. The resulting resin composition thereby provides excellent appearance, heat resistance, dielectric performance and peeling strength.

Description

technical field [0001] The invention belongs to the technical field of copper-clad laminates, and in particular relates to a resin composition and a prepreg and a laminated board using the resin composition. Background technique [0002] Polyphenylene ether resin has excellent water resistance, dimensional stability, flame retardancy and dielectric properties, and can be mixed with other resins to obtain a resin composition with more excellent comprehensive properties. Therefore, it is widely used as a raw material in various fields, for example, plumbing fixtures, electrical boxes, automobile parts, and coated wires, copper foil laminates and printed circuits, etc. [0003] Although the copper foil laminate based on polyphenylene ether resin can obtain excellent dielectric properties, in the application of the prior art, only the simple physical blending of polyphenylene ether resin and other resin compositions is used to form a uniform glue varnish, which is impregnated in...
