Embodiment 1

[0044] Add bisphenol A cyanate monomer into dimethylacetamide, heat to 70-80°C, stir while heating to make a homogeneous solution with a solid content of 55%; add dibutyltin dilaurate as a catalyst, The concentration of the catalyst was 200ppm, the reaction was stirred at 150°C for 15min, and the temperature was rapidly cooled to room temperature to obtain a cyanate resin gel (Gel-CE-01).

Embodiment 2

[0046] Add bisphenol A type cyanate monomer into dimethylacetamide, heat to 70-80°C, stir while heating to make a homogeneous solution with a solid content of 50%, add dibutyltin dilaurate as a catalyst, The concentration of the catalyst was 500ppm, the reaction was stirred at 140° C. for 12 minutes, and the temperature was rapidly cooled to room temperature to obtain a cyanate resin gel (Gel-CE-02).

Embodiment 3

[0048] Add bisphenol A cyanate monomer into dimethylacetamide, heat to 70-80°C, stir while heating to make a homogeneous solution with a solid content of 30%, add dibutyltin dilaurate as a catalyst, The concentration of the catalyst was 800ppm, and the reaction was stirred at 150° C. for 11 minutes, and the temperature was rapidly lowered to room temperature to obtain a cyanate resin gel (Gel-CE-03).

Abstract

The invention provides cyanate ester resin gel as well as a preparation method and application thereof, and relates to the technical field of cyanate ester resin. The cyanate resin gel is prepared by the following method: taking a bisphenol A cyanate monomer, adding an organic solvent, and heating to prepare a homogeneous solution with the solid content of 30-60%; the homogeneous solution is taken, an organic tin catalyst is added, the concentration of the catalyst in a reaction system is 300-1200 ppm, the mixture is heated to 130-155 DEG C, a polymerization reaction is carried out, gel is formed, and the cyanate resin gel is obtained. By adopting the method, the gelatinous cyanate ester resin prepolymer can be obtained at a relatively low temperature within a relatively short time, the molecular weight of the prepolymer is controllable, the molecular structure is clearer, the prepolymer can be applied to 5G high-frequency resin, and the dielectric property, the mechanical property and the mechanical property are favorably improved.

Description

technical field [0001] The invention relates to the technical field of cyanate ester resins, in particular to a cyanate ester resin gel and its preparation method and application. Background technique [0002] Cyanate resin (CE resin) is a new type of high-performance thermosetting resin developed in recent years, and its monomer (CE monomer) contains two or more cyanate functional groups. The cured cyanate ester has excellent dielectric properties, heat resistance, mechanical properties, and good processing properties. Its comprehensive properties are superior to ordinary epoxy resins and bismaleimide resins. There are a wide range of applications in the fields of plates, wave-transparent material substrates, and structural composite materials for aerospace. Cyanate resin reacts with bismaleimide (BMI) to obtain bismaleimide-triazine resin (BT resin). BT resin has excellent comprehensive properties such as good heat resistance, low dielectric constant, small thermal expan...
