The invention discloses a peel-off-proof environmental-friendly interior wall water-based coating. The peel-off-proof environmental-friendly interior wall water-based coating comprises, 100 to 120 parts of modified polyurethane emulsion, 15 to 20 parts of a composite filling material, 4 to 6 parts of a dodecanol ester, 2 to 4 parts of sodium dodecyl sulfate, 0.1 to 0.3 part of emulsifier OP-10, 0.3 to 0.5 part of an antifoaming agent, 0.4 to 0.6 part of glycerin, 0.1 to 0.2 part of polyvinyl alcohol, 0.2 to 0.3 part of hydroxyethyl cellulose, 0.2 to 0.4 part of a levelling agent, 0.1 to 0.3 part of carboxymethyl chitosan, 1 to 1.2 parts of Si69, and 20 to 25 parts of water. The peel-off-proof environmental-friendly interior wall water-based coating possesses excellent caking properties, water resistance, mechanical properties, and environmental protection performance, and peeling off is not easily caused.
