Zusammenfassung: | The invention discloses aqueous high-temperature-resistant thermosetting methylphenyl silicone resin and a preparation method thereof. The aqueous high-temperature-resistant thermosetting methylphenylsilicone resin is characterized in that the structural formula of the aqueous high-temperature-resistant thermosetting methylphenyl silicone resin is shown in a formula (I). (Please see the specification for the formula I). The preparation method comprises the following steps that (1) a sol-gel method is adopted to obtain a hydrophilic silane prepolymer; and (2) the hydrophilic silane prepolymeris grafted onto organic silicone resin to obtain the aqueous high-temperature-resistant thermosetting methylphenyl silicone resin, a reaction formula is shown in a formula (II): (Please see the specification for the formula II). The aqueous high-temperature-resistant thermosetting methylphenyl silicone resin and the preparation method have the beneficial effects that a controllable hydrophilic group can be given to the sil |
