• Subjects: MANUFACTURE BY DRY PROCESSES OF ARTICLES, WITH OR WITHOUTORGANIC BINDING AGENTS, MADE FROM PARTICLES OR FIBRES CONSISTINGOF WOOD OR OTHER LIGNOCELLULOSIC OR LIKE ORGANIC MATERIAL; NAILING OR STAPLING MACHINES IN GENERAL; PERFORMING OPERATIONS; TRANSPORTING; WORKING OR PRESERVING WOOD OR SIMILAR MATERIAL

The invention relates to a particle board with low formaldehyde emission and the preparation method, wherein, the preparation method comprises the following steps: grinding the tea waste into fibrous or powder material; well mixing the fibrous or powder material and wood chips; applying adhesive to form mixture; forming the mixture into billets and pressing into particle boards. Ammonia or alkaline salt solution can be sprayed on the tea waste before being ground for activating treatment. The preparation method has the advantages that the tea waste and the wood chips are mixed for use; formaldehyde emission in the particle board is fundamentally reduced through the chemical reaction of the tea waste and the formaldehyde, the effect is obvious, permanent and free from rebound; the mechanical property of the prepared particle board is not reduced, but increased somewhat.
