Synthetic wood meal

摘要

A synthetic wood meal for a pellet that enables to manufacture a molded product with no deformation such as warping and distortion or, if any, deformation that can be alleviated to a practically non-problematic level and also features high mechanical strength. The synthetic wood meal comprises 30 wt % to less than 45 wt % of a thermoplastic resin including polypropylene or a mixed material of polypropylene and polyethylene; 50 wt % to 35 wt % of a wood meal having a bulk density of 0.15 to 0.21 g/ cm3 and a mean fiber length of 101 to 189 μm in which 19 to 29% or less of the wood meal having a shortest fiber length of 60 μm or less, and 9 to 20% or less of the wood meal having a shortest fiber length of 30 μm or less; and an additive including a reinforcing agent.

1. A synthetic wood meal for a pellet used for extrusion molding of a molded wood product comprising:
30 wt % to less than 45 wt % of a thermoplastic resin including polypropylene (PP) or a mixed material of polypropylene (PP) and polyethylene (PE) with the melt index of 2 to 5 g/10 minutes; 50 wt % to 35 wt % of a wood meal having a bulk density of 0.15 to 0.21 g/cm3 and a mean fiber length of 101 to 189 μm in which 19 to 29% or less of the wood meal having a shortest fiber length of 60 μm or less, and 9 to 20% or less of the wood meal having a shortest fiber length of 30 μm or less; and an additive including a reinforcing agent.
