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.

Description

technical field [0001] The invention relates to a coating for building interior walls, in particular to a high-temperature steam-resistant interior-wall environmentally friendly latex paint suitable for protection and decoration of building interior wall surfaces in high-temperature steam environments. Background technique [0002] In recent years, with the development of the national economy and the continuous improvement of people's living standards, a large number of enterprises that serve people's daily consumer goods have emerged, such as food factories, breweries, paper towel factories, printing and dyeing factories, condiment factories, etc., such The common feature of enterprises is that high-temperature steam is released during the production process, and if it is accumulated indoors, it will easily have adverse effects on roofs and walls. Mold growth and condensation are common diseases, and corrosion will form over time. Traditional latex paint is prone to bubblin...
