Double-component high-hardness and high-temperature-resistance organic silicon pouring sealant and manufacturing method thereof

The invention discloses a double-component high-hardness and high-temperature-resistance organic silicon pouring sealant and a manufacturing method thereof. The double-component high-hardness and high-temperature-resistance organic silicon pouring sealant can be applied to indoor and outdoor electronic devices and encapsulation needing to resist a high-impact environment and can improve the heat conduction performance, the conductivity and the flame retardancy according to environmental demands. Base rubber is prepared from 107 silicone rubber and alpha-cyanoacrylate adhesive; a crosslinking agent adopts epoxy trimethoxysilane; a heat conduction material is mainly prepared from aluminum oxide; a flame retardant material adopts aluminum hydroxide; a conductive material is prepared from aluminum silver powder and copper powder; a plasticizer adopts MDT silicone oil; a catalyst adopts dibutyltin dilaurate. During use of the double-component high-hardness and high-temperature-resistance organic silicon pouring se
