Zusammenfassung: | The invention discloses an acid-fog-corrosion-resistant two-component silicone structural adhesive and a preparation method thereof. The acid-fog-corrosion-resistant two-component silicone structural adhesive comprises a component A and a component B. The component A comprises the following raw materials in parts by mass: 90-110 parts of 107 base adhesive, 85-135 parts of filler and 5-25 parts of simethicone; the component B comprises the following raw materials in parts by mass: 5-9 parts of fumed silica, 15-20 parts of carbon black, 25-32 parts of simethicone, 15-38 parts of a cross-linking agent, 18-45 parts of a coupling agent and 0.01-0.1 part of a catalyst, and the coupling agent comprises 10-25 parts of an acrylic acid modified amino silane oligomer. The acrylic acid modified amino silane oligomer can react with 107 base adhesive for crosslinking, and hydrophobic alkyl groups are introduced, so that the compactness and waterproof impermeability of the silicone structural adhesive are improved, acid mis |
