Composite section material for coating wood surface on surface of plastic/wood-plastic sectional material and manufacturing method therefor

The invention provides a composite sectional material covering bark on the surface of a plastic/wood plastic sectional material and a manufacture method thereof, in order to overcome the defects of slow solidification speed, easy defect generation of glue films and unstable bonding caused by the mode of applying single cold glue to single side for bonding a plastic surface and a wood layer in the prior art. The method comprises the following steps: A. carrying out stain and dust removal treatment to the surface to be covered of the plastic/wood plastic sectional material; B. applying hot melt adhesive to the inner surface of the bark, and applying interface affine agent to the surface to be covered of the plastic/wood plastic sectional material which is subjected to the step A; and C. rolling and covering the bark on the surface of the plastic/wood plastic sectional material through a forming roll of a covering machine, so that the inner surface of the bark and the surface to be covered of the plastic/wood plastic sectional material can be bonded together. With the manufacture method, the bonding power between the surface of the bark and the surface of the plastic/wood plastic sectional material can be greatly improved, and the glue film has excellent quality, so that the plastic/wood plastic sectional material and the bark can be firmly bonded.
