Strong air purifying emulsion paint and preparation method thereof

The invention provides strong air purifying emulsion paint and a preparation method thereof. The emulsion paint is prepared from the following components in parts by mass: 40 to 55 parts of a water-based acrylic emulsion, 60 to 80 parts of a functional filler, 10 to 20 parts of a curing agent and 15 to 25 parts of water. According to the strong air purifying emulsion paint and the preparation method thereof, a salicylic acid and citric acid grafted zeolite molecular sieve is used as a functional filler to be added into a water-based acrylic emulsion substrate, wherein the zeolite molecular sieve serves as an air purifying reaction place; and the salicylic acid and the citric acid which are grafted on the surface of zeolite serve as main reactants for purifying the air. The paint overcomesthe defects that the conventional air purifying paint is low in efficiency and low in weather resistance, harmful gas is removed not obviously, and harmful gas is released secondarily; the harmful gascan be removed quickly wi
