The invention discloses a waterproof modified expanded perlite thermal insulation board and a production method thereof. The thermal insulation board comprises the following components, by weight: 20-30 parts of cement, 5-8 parts of fly ash, 2-5 parts of popyltrimethoxysilane, 5-10 parts of polyacrylate emulsion, 50-70 parts of modified expanded perlite, 0.7-2.9 parts of sodium dodecylbenzenesulfonate, 5-10 parts of additives, 1-3 parts of quicklime, 0.1-0.5 parts of PP fiber, 0.5-2 parts of zirconium fiber, 5-10 parts of kaolin and 10-20 parts of water. According to the modified expanded perlite thermal insulation board, cement, fly ash, kaolin, PP fiber and other organics and inorganics are adopted as raw materials, such that industrial and mining waste materials are effectively utilized, and no toxic or harmful substance is added. Therefore, the modified expanded perlite thermal insulation board is green and environment-friendly. The modified expanded perlite thermal insulation board has the advantages of
