Abstract

The invention discloses a modified hydrocarbon resin prepolymer, a modified hydrocarbon-DCPD epoxy composite material copper-clad plate and a preparation method thereof. The modified hydrocarbon resinprepolymer is prepared by mixing and reacting 50-200 parts by mass of hydrocarbon resin, 50 parts by mass of a resin mixture containing double-bond benzoxazine resin / modified polyphenyl ether resin,1-5 parts by mass of an initiator A and 110-280 parts by mass of a solvent A through a micro-channel reactor and removing part of the solvent. The modified hydrocarbon-DCPD epoxy composite material copper-clad plate is prepared by thermally curing a composition and a copper foil, wherein the mass ratio of a modified hydrocarbon resin prepolymer to DCPD epoxy resin to an inorganic filler to an initiator B to an accelerant A to a reinforcing material is 90: (10-30): (40-100): (0.01-1): (0.01-1): (70-200); the ceramic has the characteristics of low dielectric constant, low dielectric loss, low water absorption, high glass-transition temperature and high peel strength.

Description

technical field [0001] The invention belongs to the field of modified hydrocarbon resin synthesis and preparation of composite material boards, and relates to a modified hydrocarbon resin prepolymer, a modified hydrocarbon-DCPD epoxy composite material copper-clad board and a preparation method. The modified hydrocarbon resin prepolymer of the present invention is especially suitable for the manufacture of high-frequency and high-speed copper clad laminates required by 5G communication. Background technique [0002] Due to the requirements of 5G communication data transmission rate and high reliability, the use of laminates and copper clad laminates has become a technical difficulty that must be overcome in terms of dielectric constant, dielectric loss factor and heat resistance. [0003] Because the polarity of C-H in the molecular chain of hydrocarbon resin is small (the electronegativity of C and H are 2.5 and 2.1 respectively), it has excellent dielectric properties (vol...
