The invention discloses a high-alkali-resistance internal wall paint which is prepared from the following raw materials in parts by weight: 42-50 parts of styrene-acrylic emulsion, 13-20 parts of modified bonding agent, 10-20 parts of calcite powder, 15-20 parts of feldspar powder, 3-4 parts of methyl hydroxyethyl cellulose, 1-2 parts of vanadium oxytrichloride, 1-3 parts of 2-methyl-1,3-propanediol, 2-3 parts of ethylene glycol, 2-4 parts of sodium monofluorophosphate, 1-2 parts of diethylene glycol butyl ether, 2-3 parts of 2,2,4-trimethyl-1,3-pentanediol mono(2-methylpropanoate), 1-2 parts of diethanolamine, 1-3 parts of sodium ethylenediamine tetramethylene phosphonate, 1-2 parts of 2-(3,4-epoxycyclohexyl)ethyltrimethoxysilane, 0.2-0.4 part of polyoxypropylene glycerol ether and 20-40 parts of deionized water. The formula components have favorable compatibility, dispersity and temperature property; the produced paint product has the advantages of firm coating, smooth surface, high adhesive force, high scrub resistance, high acid / alkali resistance, high fouling resistance, high safety and environmental protection; and the added modified bonding agent further enhances the bonding property of the coating, so that the coating can not easily fall off, and the properties of the paint are enhanced.
