Application of high-efficient environment-friendly artificial board formaldehyde catching agent in chipboard production

The invention relates to a high-efficient environment-friendly artificial board formaldehyde catching agent, the high-efficient environment-friendly artificial board formaldehyde catching agent comprises the components of, by mass, 1%-15% of sulfites, 30%-60% of water and 3%-25% of sodium hydroxide, and the sum of the percentages of the components is 100%. The sulfites are sodium pyrosulfite, thesodium hydroxide is used for adjusting the pH value of a solution to a specified range, and sodium pyrosulfite solid and a sodium pyrosulfite solution are obtained. An environment-friendly chipboard with low formaldehyde emission is obtained by further optimizing the process; and the chipboard prepared by the high-efficient environment-friendly artificial board formaldehyde catching agent is stable in combination property and not prone to being affected by temperature and humidity changing, and has the characteristics of environmental protection, reliable use, low process cost and the like. 本发明涉及种高效环保型人造板甲醛捕捉剂，它由以下组份按
