To provide a dust scattering prevention material having a highly effective dust scattering prevention property, as well as enhanced durability.SOLUTION: A dust scattering prevention material comprises: water; polyvinyl acetate; an ethylene-vinyl acetate copolymer; polyvinyl alcohol; and a thickener. In the dust scattering prevention material: a polyvinyl acetate concentration is 1 to 10 vol.% when the total volume of components other than the thickener is 100 vol.%; an ethylene-vinyl acetate copolymer concentration is 0.1-5 vol.% when the total volume of components other than the thickener is 100 vol.%; a polyvinyl alcohol concentration is 0.05-1.0 vol.% when the total volume of components other than the thickener is 100 vol.%; and a thickener concentration is 0.1 to 1.0 mass% when the total weight of components other than the thickener is 100 mass%.SELECTED DRAWING: None 【課題】粉塵の飛散防止効果が高く、且つ、耐久性が向上した粉塵飛散防止材を提供する。【解決手段】水と、ポリ酢酸ビニルと、エチレン・酢酸ビニル共重合体と、ポリビニルアルコールと、増粘剤とを含有する粉塵飛散防止材。この粉塵飛散防止材は、増粘剤以外の成分の合計体積を１００体積％としたときのポリ酢酸ビニルの濃度が１〜１０体積％であり、増粘剤以外の成分の合計体積を１００体積％としたときのエチレン・酢酸ビニル共重合体の濃度が０．１〜５体積％であり、増粘剤以外の成分の合計体積を１００体積％としたときのポリビニルアルコールの濃度が０．０５〜１．０体積％であり、増粘剤以外の成分の合計重量を１００質量％としたときの増粘剤の濃度が０．１〜１．０質量％である。【選択図】なし
