Abstract

The invention discloses a high-temperature steam resistant environment-friendly emulsion paint for interior walls, which comprises the following components shown in the specificatio in percentage by weight: 30.0-40.0% of styrene-acrylic emulsion, 30.0-40.0% of color filler, 1.5%-2.0% of film forming adjuvant, 1.0%-3.0% of propylene glycol, 0.8%-2.0% of dispersing agent, 0.2%-1.0% of wetting agent, 0.1%-0.5% of defoamer, 0.02%-0.05% of antiseptic bactericide, 0.1%-0.2% of pH adjuster, 0.2%-2.0% of thickener, and balance of water. The emulsion paint disclosed by the invention can effectively protect a wall body which is in a high-temperature steam environment for a long time; and the emulsion paint is ultra-low in VOC (volatile organic compound) content, non-toxic and harmless, and can be widely applied to the protection of wall bodies in various high-temperature steam environments.
