High-temperature-resisting thermal recovery cement and preparation method thereof

The invention discloses high-temperature-resisting thermal recovery cement and a preparation method thereof. The thermal recovery cement comprises the following components in parts by weight of 55-65 parts of aluminate cement grog, 10-30 parts of phosphorite dregs, 10-30 parts of slags, 1-3 parts of ceramic fibers and 1-3 parts of rubber powder. The preparation method comprises the following steps of weighing the aluminate cement grog, the phosphorite dregs and the slags, mixing so as to obtain a mixing powder body, pouring the mixing powder body into a ball mill for grinding until the specific surface area of 250-300m /kg is achieved, adding the ceramic fibers and the rubber powder, and stirring for ten minutes in a mixing manner to obtain the high-temperature-resisting thermal recovery cement. The high-temperature-resisting thermal recovery cement and the preparation method thereof provided by the invention have the advantages that an engineering property of the thermal recovery cement is easy to regulate,
