Abstract

The invention discloses a light solid wood sectional material which comprises a paulownia solid wood sectional material with the thickness being 2 to 6mm. The paulownia solid wood sectional material is prepared from 20 to 40 percent by weight of polymer resin with the porosity being 8 to 20vol percent, the density being 0.32 to 0.56g/cm<3> when the water content is 6 percent, the static bending intensity being 30 to 40MPa, and the elasticity modulus being 4100 to 4500Mpa. The light solid wood sectional material provided by the technical scheme of the invention has the characteristics of convenience in transportation, high strength, and good decorative effect.

Description

technical field [0001] The invention relates to the technical field of wood materials, in particular to a lightweight solid wood profile and a manufacturing method thereof. Background technique [0002] As an environmentally friendly material, wood has always been loved by people, and it appears in large quantities in indoor and outdoor decoration. With the shortage of precious hard broad-leaved wood resources, fast-growing wood has been paid more and more attention. The natural fast-growing solid wood material has natural patterns and natural intimacy, and because of its low density, it is very beneficial in transportation. It is an environmentally friendly and sustainable material in the whole process from raw material growth to product logistics and transportation. However, fast-growing solid wood materials have defects such as large dry shrinkage and wet expansion, poor aging resistance, and limited mechanical properties, which lead to short service life and poor user ex...
