ABSTRACT:
The present invention relates to the technical field of manufacturing engineer wood floor for indoor decoration, and in particular to a manufacturing method that does not release any dissociated formaldehyde. The manufacturing steps are as the followings: Mix the adhesive agent; pour the mixed adhesive agent on a glue spreader at the linear velocity of ≦20 meters/minute; deliver the wooden middle boards to the glue spreader to carry out spreading glue; superimpose wooden middle boards having been coated with glue longitudinally and latitudinally, and deliver them to a cold press for cold press; put the rough middle boards having been coldly pressed on a hot press for hot pressing, in order to make them become base material of engineer wood floor; Stick decorative surface material on the base material of engineer wood floor in order to make them become a engineer wood floor; and form, paint, and pack the engineer wood floor finally.
