Provided is an adhesive for producing a corrugated cardboard, which utilizes natural ore powder having anti-bacterial, anion- and far infrared ray-emitting and deodorizing effects to allow a corrugated cardboard to maintain its freshness for a long time, and thus is useful for storage or transport of agricultural products. The adhesive for producing a corrugated cardboard is obtained by pulverizing natural ore into microparticles having a particle size of 600-1000 mesh and by mixing 13-17 wt% of the natural ore powder with 80-85 wt% of corn starch and 2-3 wt% of sulfuric acid. In the adhesive, the natural ore includes silicon dioxide(SiO2), ferrous oxide(Fe2O3), titanium dioxide(tiO2), alumina(Al2O3), calcium oxide(CaO), magnesium oxide(MgO), potassium oxide(K2O), sodium oxide(Na2O) and germanium(Ge). |
