The invention discloses environment-friendly insect-proof paint. The paint is prepared from the following ingredients as raw materials in parts by weight: 10-20 parts of pyrethroid compound, 6.0-12 parts of sodium hydroxide, 1.0-3.5 parts of glycerine, 30-50 parts of water, 1.5-8.0 parts of sericite powder, 20-30 parts of active carbon, 3.5-12 parts of talcum powder, 30-40 parts of synthetic resin emulsion, 5.0-10 parts of polyethylene wax, 8.0-16 parts of acrylate copolymer, 2.5-6.0 parts of gypsum and 5.0-10 parts of eucalyptus oil, wherein the average grain diameter of the sericite powder is 15-30nm, and the average grain diameter of the talcum powder is 20-40nm. According to the environment-friendly insect-proof paint, the water, the synthetic resin emulsion and the acrylate copolymer serve as solvents, the pyrethroid compound serves as a main insect-proof ingredient, the pungent smell in the paint is reduced by the eucalyptus oil and the active carbon, and the pungent smell can be absorbed. The environment-friendly insect-proof paint disclosed by the invention is good in decorative effect and free of the pungent smell, can have a relatively good insect-proof effect during decoration, does not cause harm to human bodies, and has the characteristics of being green, environmentally friendly, healthy and safe.
