Silicone structural adhesive resistant to corrosion of cleaning agent and preparation method of silicone structural adhesive

The invention discloses a silicone structural adhesive resistant to corrosion of a cleaning agent and a preparation method thereof.The silicone structural adhesive is obtained by mixing a component A and a component B. The component A comprises, by weight, 100 parts of 107 base adhesive; 80 to 130 parts of nano calcium carbonate; 5 to 30 parts of a plasticizer; the component B comprises the following raw materials in parts by weight: 5-10 parts of fumed silica; 15 to 20 parts of carbon black; 25 to 30 parts of a plasticizer; 15 to 40 parts of a cross-linking agent; 15 to 40 parts of a coupling agent; 15 to 40 parts of a tackifying auxiliary agent; 0.01 to 0.1 part of a catalyst; the tackifying aid is a silane oligomer, and the silane oligomer comprises the following raw materials: an epoxy silane coupling agent and a sulfydryl silane coupling agent in a weight ratio of (1-2): (2-3). The silicone structural adhesive disclosed by the invention has excellent effects of resisting permeation and corrosion of a cle
