Abstract
Disclosed are a hollow artificial log and a manufacturing method thereof. The method includes: splicing and fixing veneers along a length direction and a width direction, respectively, to obtain a spliced veneer; gluing the spliced veneer on one side to obtain a glued veneer; subjecting the glued veneer to winding and forming around a forming die along a length direction of the glued veneer to obtain a formed body; subjecting the formed body to hot-pressing curing in a hot-pressing die to obtain a cured body; and taking out the cured body from the forming die to obtain the hollow artificial log; wherein an adhesive for the gluing comprises a melamine-urea-formaldehyde copolycondensation resin, and the forming die is a cylinder.
