Salt-spray-corrosion-resistant two-component silicone structural adhesive and preparation method thereof

The invention discloses a salt-spray-corrosion-resistant two-component silicone structural adhesive and a preparation method thereof.The salt-spray-corrosion-resistant two-component silicone structural adhesive comprises a component A and a component B. The component A is prepared from, by mass, 85-105 parts of 107 base adhesive, 90-120 parts of filler and 10-30 parts of simethicone; the component B comprises the following raw materials in parts by mass: 4-10 parts of fumed silica, 15-20 parts of carbon black, 25-32 parts of simethicone, 12-40 parts of a cross-linking agent, 20-46 parts of a coupling agent and 0.01-0.1 part of a catalyst, and the coupling agent comprises 9-26 parts by mass of an acrylic acid modified epoxy silane oligomer. Alkyl groups contained in epoxy groups and acrylic acid belong to hydrophobic groups, so that the possibility that moisture and chloride molecules contained in the moisture pass through the silicone structural adhesive in a salt spray environment is greatly reduced, and the
