The invention discloses a method for manufacturing an anti-
insect and anti-mold
oriented strand board with full
eucalyptus leftover materials. The manufacturing method comprises the following steps of: preparing materials,
drying, peeling and removing impurities, sorting and storing, respectively gluing on a surface core layer, hierarchically paving, in advance
hot press molding, and sanding wood finishes; an
isocyanate sawdust powder hybrid adhesive is coated on the surface, and an anti-
insect and anti-mold composite
urea-
formaldehyde resin adhesive is coated on the core layer;
wood shavings on the core layer are divided into three-layer structures, comprising intermediate layer of core layer, upper
surface layer of core layer and lower
surface layer of core layer; the intermediate layer of the core layer is paved longitudinally, and the upper
surface layer of the core layer and the lower surface layer and surface layer of the core layer are paved horizontally. For the
oriented strand board prepared by the method, the
static bending intensity in a parallel direction is in a scope of 33-39 MPA, the parallel elasticity modulus is in the scope of 4614-4779 MPA, the vertical elasticity modulus is in the scope of 1504-1771 MPA, the thickness swelling rate of water absorption in 24 h is in the scope of 10%-17%, and the vertical nail-holding power reaches up to 89000N. In the manufacturing method, a problem that the board is easy to suffer from
erosion of white ants and moths is thoroughly solved by adding an anti-
insect and anti-mold additive, and the service life of the board is prolonged.
