Description
Technical Field
The invention belongs to the field of high-frequency communication materials, and particularly relates to a multifunctional modified resin blended prepreg hydrocarbon composition, application thereof and a method for preparing a high-frequency high-speed copper-clad plate by using the composition.
Background
The copper-clad plate is one of electronic communication core materials, and has higher and higher performance requirements based on the rapid development of the current information processing high speed and signal transmission high frequency. The traditional epoxy copper-clad plate has good thermal mechanical property and easy processing through formula improvement and process improvement, the price is suitable, and the requirements of the electronic communication industry are basically met, however, the epoxy plate has higher dielectric constant and higher dielectric loss, and can not meet the requirements of the high-frequency and high-speed communication field. The polyphenyl ether has low dielectric constant and dielectric loss, can be used as a high-frequency high-speed circuit board material, but has the defects of pores and the like in later PCB processing due to the high-melting property, and the water absorption rate of the substrate is higher, the thermal expansion coefficient is high, so that the polyphenyl ether cannot be applied to the communication antenna field with low water absorption rate and low thermal expansion coefficient, and the like.
The polytetrafluoroethylene has the advantages of excellent dielectric property, extremely low dielectric constant, extremely low dielectric loss, small influence of the dielectric property of the polytetrafluoroethylene along with temperature and environmental change and the like, and is widely applied to high-frequency high-speed electronic communication materials at present.
The high-frequency special prepreg is used as a necessary material of a polytetrafluoroethylene-based high-frequency copper-clad plate multilayer plate, and along with the rapid development of the polytetrafluoroethylene-based copper-clad plate in the field of high-frequency communication, the high-frequency special prepreg matched with the polytetrafluoroethylene-based copper-clad plate is more and more emphasized and developed. The performance of the prepreg directly affects the performance of the multilayer board. The high-frequency special prepreg mainly comprises a modified epoxy group, a modified polyphenylene ether group, a hydrocarbon series and the like at present. The hydrocarbon series prepreg has more excellent dielectric property, low dielectric constant, low dielectric loss, extremely low water absorption and other properties, and is widely applied to the preparation of multilayer boards of high-frequency and high-speed copper clad plates. However, most of hydrocarbon resins are nonpolar and have poor compatibility with fillers, so that poor thermo-mechanical properties, poor heat resistance, poor peel strength and the like occur, and the application of the hydrocarbon curing sheet is affected. At present, the high density, complication and multifunctionality of high-frequency copper-clad plate lines have higher requirements on the copper-clad plate and a prepreg matched with the copper-clad plate.
Therefore, the development of the hydrocarbon-based prepreg with low dielectric constant, low dielectric loss, excellent heat resistance, good thermomechanical property and stable performance is of great significance for the multilayer high-frequency copper-clad plate.

The prepregs and laminated double-sided boards of examples 1 to 5 and comparative examples 1 to 3 had the following properties:
as comparative example 1, the non-modified polyolefin polymer was not added, the non-polar resin and the filler containing abundant surface hydroxyl groups could not be completely mixed and dispersed to cause phase separation, and no crosslinking assistant caused a significant decrease in thermal shock property at T288 ℃, resulting in poor thermo-mechanical properties and heat resistance of the prepreg. As in comparative example 2, the addition of a crosslinking coagent increases the Tg, but the effect is not significant and there is no significant improvement in the other thermo-mechanical properties as such. As comparative example 3, several unmodified copolymers were also used for blend modification while adjusting the amount of the crosslinking agent up, but the thermo-mechanical properties were not significantly improved.
As in examples 1 to 5, the hydroxyl-terminated modified polyolefin copolymer was used, and the modified hydroxyl group had good compatibility with the hydroxyl group on the surface of the filler, thereby improving the adhesion of each component, increasing the thermo-mechanical properties of the prepreg, improving the heat resistance, and improving the performance stability and reliability of the material. The crosslinking assistant and different crosslinking agents are added for compounding, so that the mechanical property, the heat resistance and the like are further improved, and the prepreg with excellent dielectric property, good heat resistance and uniform material is prepared.
