Embodiment 1

[0029] The preparation of embodiment one filler

[0030] Disperse 1Kg of triphenylchlorosilane in deionized water, then add 500g of diethylmagnesium and 2092-ethyl-1-hexanol titanium; then conduct a hydrothermal reaction at 120°C for 3 hours; then filter the reaction solution and bake the filter cake After drying, calcinate at 600°C for 1 hour, cool naturally and then sinter at 950°C for 2 hours, add the obtained powder into ethanol, disperse evenly, then add 10g of polyoxyethylene sorbitan monooleate, and stir at 60°C for 2 hours , and finally dried to obtain a filler (particle size of 450nm to 680nm); 1000g of the filler was added to 1.6Kg of diglycidyl phthalate, and stirred at 125°C for 1 hour to obtain an active filler.

Embodiment 2

[0032] According to the composition of Table 1 and Table 2, proceed according to the following steps, mix cyclopentadienyl iron tricarbonyl and cyanate monomer, stir at 95°C for 10 minutes, then add amino compound and aliphatic glycidyl ether in turn, at 120 Stir for 1 hour at ℃, then add dipropylene phthalate, stir at 120°C for 0.5 hours, and obtain a resin prepolymer after cooling; then add the resin prepolymer to methyl ethyl ketone and stir for 1 hour; add active filler and propylene Nitrile; then add PMA and diallyl diphenyl ether, and continue to stir for 2.5 hours to obtain glue.

Embodiment 3

[0038] Example 3 Preparation of high-frequency electronic dielectric material

[0039] Coat the above glue with electronic grade glass cloth and bake in an oven at 170°C for 2 minutes to prepare a prepreg; cut off the burrs of the prepreg; take 5 pieces of lamination and cover both sides with a release film, The high-frequency electronic dielectric material can be obtained by hot pressing.

[0040] The conditions of hot pressing adopt the method of gradually increasing temperature and increasing pressure. The temperature is raised from 50°C to 180°C for 10 minutes, kept for 60 minutes, then raised to 200°C for 10 minutes, kept for 90 minutes, then raised to 230°C for 5 minutes, kept for 90 minutes, and finally cooled to 50°C for 180 minutes. ; 1min pressure from 0Kg / cm 2 Rise to 15Kg / cm 2 , then keep the pressure for 45min, then rise to 20Kg / cm in 1min 2 Keep the pressure for 50 minutes, and rise to 35Kg / cm in the last 1 minute 2 , keep the pressure for 200min.
