The invention relates to a modified zeolite powder inorganic environment-friendly building coating and a preparation method thereof. The modified zeolite powder inorganic environment-friendly building coating comprises the following components in percentage by weight: 15%-20% of light calcined magnesia powder, 5%-10% of magnesium sulfate heptahydrate, 35%-45% of modified zeolite powder, 20%-25% of water, 10%-15% of heavy calcium carbonate, 0.5%-1.0% of an additive, 0.3%-0.5% of fibers, 0.3%-0.5% of hydroxypropyl methyl cellulose and 0.3%-0.5% of redispersible rubber powder. The modified zeolite powder and the low-quality light calcined magnesia are adopted as main raw materials to prepare the inorganic environment-friendly building coating, a base material is an inorganic cementing material, and the inorganic environment-friendly building coating does not contain an organic solvent, does not contain formaldehyde, does not mildew and does not pollute the environment and has the advantages of being good in construction performance, high in bonding strength, fireproof, capable of adsorbing formaldehyde and capable of adjusting indoor humidity.
