Embodiment 1

[0031] First, mix 100 parts (parts by mass) of bisphenol A type cyanate resin with 10 parts of methyl toluene ethynyl silane resin in acetone, and after completely dissolving, heat and distill off the solvent to prepare methyl toluene Ethynyl silane resin modified bisphenol A type cyanate resin blend. The above blend is cured under a certain curing process. The curing process is 110°C / 1h→150°C / 1h→200°C / 2h→250°C / 2h→300°C / 4h to obtain a methyl tolanyl Silane resin modified bisphenol A cyanate resin.

Embodiment 2

[0033] First, mix 100 parts (parts by mass) of bisphenol A type cyanate resin with 80 parts of tetraphenylethynyl silane resin in acetone, and after completely dissolving, heat and distill off the solvent to prepare tetraphenylethynyl silane resin Modified bisphenol A type cyanate resin blend. The above blend is cured under a certain curing process. The curing process is 110°C / 1h→150°C / 1h→200°C / 4h→250°C / 4h→300°C / 4h to obtain a tetraphenylethynyl silane resin Modified bisphenol A cyanate resin.

Embodiment 3

[0035] First, mix 100 parts (parts by mass) of phenolic cyanate resin with 50 parts of methyltriphenylethynyl silane resin in acetone, and after completely dissolving, heat and distill off the solvent to prepare methyltriphenylethynyl silane resin. Silane resin modified phenolic cyanate resin blend. The above blend is cured under a certain curing process. The curing process is 110°C / 1h→150°C / 1h→200°C / 2h→250°C / 2h→300°C / 4h to obtain a triphenylethynyl silane resin Modified phenolic cyanate resin.

Abstract

The invention relates to cyanate resin modified by phenylacetylene base silane resin and a preparation method thereof. The preparation method is technically characterized by comprising the steps of: mixing 100 parts by weight of the cyanate resin and 1-100 parts by weight of the phenylacetylene base silane resin in a solvent, then, distilling to remove the solvent, and curing according to a certain curing process to form a three-dimensional network structure. Compared with the traditional modification method of the cyanate resin, in the preparation method, the phenylacetylene base silane resin is soluble in the common organic solvent and has favorable compatibility with the cyanate resin, which can effectively improve the heat resistance and the thermal oxidation property of the cyanate resin. The modification system prepared in the invention has excellent heat resistance, favorable mechanical property and dielectric property and can be sued as matrix resin of the heat resistant and wave-transmitting material.

Description

technical field [0001] The invention belongs to a novel polymer material and a preparation method thereof, in particular to a phenylethynyl silane resin modified cyanate resin and a preparation method thereof. Background technique [0002] Cyanate resin is a phenol derivative containing two or more cyanate functional groups in its molecular structure, which can undergo tricyclization reaction under the action of heat or a catalyst to form a body-shaped structure containing a triazine ring. Cyanate resin has excellent dielectric properties, good heat resistance, soluble in common organic solvents, and has good wettability with glass fiber, carbon fiber and other reinforcing materials, suitable for autoclaves, vacuum bags and Resin transfer molding and other advanced composite molding processes. [0003] The modification of cyanate esters by domestic and foreign researchers mainly focuses on the toughening of cyanate esters. Epoxy resins, bismaleimide resins or thermoplastic ...
