Temperature-resistant acid-resistant organosilicon adhesive used for chimneys, and preparation method thereof

The invention relates to a temperature-resistant acid-resistant organosilicon adhesive used for chimneys, and a preparation method thereof. The temperature-resistant acid-resistant organosilicon adhesive used for chimneys comprises a component A and a component B; the component A is prepared from, by weight, 100 parts of an alpha-silane terminated polyether, 20 to 100 parts of diatomite, 10 to 50parts of silicon nitride, and 10 to 50 parts of white carbon black; the component B is prepared from, by weight, 100 parts of silicone oil, 10 to 50 parts of carbon black, 1 to 20 parts of a cross-linking agent, 1 to 10 parts of a coupling agent, and 0.1 to 5 parts of a catalyst. The structure formula of the alpha-silane terminated polyether is disclosed in the invention, wherein n ranges from 100to 5000, and R is used for representing methyl or ethyl. The cross-linking agent is prepared from a mixture of methyltrimethoxysilane and tetramethoxysilane. The temperature-resistant acid-resistantorganosilicon adhesive is e
