Embodiment 1

[0032] First, mix 100 parts of methyl toluene silane resin (parts by mass), 10 parts of 1,7-bis(dimethylhydrogensilane)-carborane in acetone, and after completely dissolving, add chlorine The acetone solution of platinum acid (concentration is 100ppm), the reaction temperature is 56°C, and the reaction time is 24h. After the reaction is completed, the solvent is distilled off by heating to prepare a 1,7-bis(dimethylhydrogensilane)-carborane / methyl tolanylsilane hybrid resin.

Embodiment 2

[0034] First, mix 100 parts (parts by mass) of methyl triphenylethynyl silane resin and 20 parts of 1,7-bis(methylphenylhydrosilane)-carborane in acetone, and after completely dissolving, add dropwise The Wllkinson catalyst (concentration is 300ppm), the reaction temperature is 56°C, and the reaction time is 24h. After the reaction, the solvent was distilled off by heating to prepare 1,7-bis(methylphenylhydrogensilane)-carborane / methyltriphenylethynylsilane hybrid resin.

Embodiment 3

[0036] First with 100 parts (mass parts) of tetraphenylethynyl silane resin, 30 parts of 1,7-bis(diphenylhydrosilane)-carborane, mix in acetone, after completely dissolving, add dropwise Karstedt catalyst ( The concentration is 300ppm), the reaction temperature is 56°C, and the reaction time is 24h. After the reaction is finished, the solvent is distilled off by heating to prepare 1,7-bis(diphenylhydrosilane)-carborane / tetraphenylethynylsilane hybrid resin.

Abstract

The invention discloses a high-temperature-resistance boron-silicon-carbon hybrid resin system, i.e. 1, 7-bis(alkyl hydrogen silane)-carborane / phenylethynyl silane hybrid resin, and a preparation method thereof. The invention has the technical scheme that the method comprises the following steps: dissolving 100 parts (mass parts) of phenylethynyl silane resin and 1 to 100 parts of 1, 7-bis(alkyl hydrogen silane)-carborane in organic solvents to be mixed; dripping catalysts for carrying out hydrosilylation reaction after the sufficient dissolution; distilling reacting substances for removing solvents after the reaction is completed; and obtaining 1, 7-bis(alkyl hydrogen silane)-carborane / phenylethynyl silane hybrid resin. Compared with the existing phenylethynyl silane resin modiciation method, the invention has the advantages that the 1, 7-bis(alkyl hydrogen silane)-carborane / phenylethynyl silane hybrid resin is dissolved in the ordinary solvents and is applicable to various advanced composite material forming processes, and the heat resistance and the heat oxidation performance of the phenylethynyl silane resin can be effectively improved. The 1, 7-bis(alkyl hydrogen silane)-carborane / phenylethynyl silane hybrid resin system prepared by the invention has excellent heat-resistance and heat oxidation performance, good mechanical property and good dielectric property, and has wide application prospects in the high-end fields such as national defense, aviation, aerospace and the like.

Description

technical field [0001] The invention belongs to a new type of polymer material and its preparation method, in particular to a high temperature resistant borosilicate carbon hybrid resin system, that is, 1,7-bis(alkylhydrogensilane)-carborane / phenylethynylsilane Chemical resin and its preparation method. Background technique [0002] As a new type of silicone resin, phenylethynyl silane is characterized by Si-C bond and C≡C bond in the molecule, which can be cross-linked and cured by the reaction of active groups in the molecule. This kind of material has the characteristics of ordinary polymers. It is used in high-end fields such as aerospace due to its excellent processing performance, excellent high temperature resistance, dielectric properties and mechanical properties. These polymers all use carbon-silicon bonds as the molecular skeleton structure, and some also contain benzene rings. There are many kinds of substituents on carbon atoms and silicon atoms, including ary...
