The invention is applicable to the field of cement waterproofing, and discloses a high-adhesion polymer cement waterproof coating and a preparation method thereof, the cement waterproof coating comprises the following components in parts by weight: a component A: 20-130 parts of a polymer emulsion, 0.5-3 parts of a silane coupling agent, 0.1-1.8 parts of a first auxiliary agent and 5-20 parts of water; the component B is prepared from the following components in parts by weight: 20 to 125 parts of inorganic filler, 1 to 5 parts of silane modified nano zinc oxide and 0.1 to 0.8 part of second aid. The polymer emulsion, the silane coupling agent and the modified nano zinc oxide are added into the cement waterproof coating, and the combination is subjected to multiple coupling through chemical bonds, so that the interface connection of organic and inorganic materials in the components is tighter, the internal structure is more compact, the strength and durability of a product are improved, meanwhile, the bonding
