Problems solved by technology

Because the reaction belongs to free radical polymerization, the polymerization speed is fast and explosive, the molecular weight distribution of the polymer is uneven, and the large number of internal dense unevenness in the product is easy to cause inevitable damage such as stress cracking and silver streaks in daily use.

Abstract

The invention discloses a modified hydrocarbon resin prepolymer, a copper-clad plate and preparation methods of the modified hydrocarbon resin prepolymer and the copper-clad plate. The modified hydrocarbon resin prepolymer is prepared by mixing and reacting 50-450 parts by mass of hydrocarbon resin, 50 parts by mass of a mixture of epoxy resin / maleimide resin containing double bonds, 1-5 parts bymass of an initiator A and 180-280 parts by mass of a solvent A through a micro-channel reactor and removing the part of the solvent; the modified hydrocarbon resin copper-clad plate is prepared froma the composition of the modified hydrocarbon resin prepolymer, high-heat-resistance high-toughness low-dielectric fluorenyl benzoxazine resin, an inorganic filler, an initiator B, an accelerator A, areinforcing material with a mass ration being 90: (10-30): (40-100): (0.01-1): (0.01-1): (70-200); the prepared modified hydrocarbon resin copper-clad plate has the characteristics of low dielectricconstant, low dielectric loss, low water absorption, high glass-transition temperature and high peel strength.

Description

technical field [0001] The invention belongs to modified hydrocarbon resin, copper-clad board (laminated board) and preparation thereof, and relates to a modified hydrocarbon resin prepolymer, copper-clad board and a preparation method thereof. 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 (volume resistivity 10 17～18 Ω m; dielectric constant (...
