Light solid wood sectional material and manufacturing method thereof

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...

Problems solved by technology

For example, Chinese patent 200410007665.1 discloses a wood impregnated resin composition and resin impregnated wood, which is a resin composition containing (meth)acrylic polymer components and free radical polymerizable monomer components. In the (meth)acrylic polymer The composition must contain a cross-linked (meth)acrylic polymer with at least one free-radical polymerizable double bond in the molecule; through the above-mentioned technical scheme, the defects such as discoloration, decay, deformation, and cracking of wood have been alleviated, but the wood The improvement of the mechanical properties after impregnation treatment is mostly accompanied by the increase of the density of the final product, that is, under the same specification, the quality of a single product is greatly improved, which increases the logistics cost of the final product and consumes more labor and man-hours during use.

[0003] Another technical solution to the existing problems in the prior art is to obtain wood-plastic composite materials by recombining wood with plastic after crushing. This technical solution has the same problem as the previous technology in the background technology, that is, the density of the final product Most of them are very large, causing troubles in the process of logistics, use and construction. In addition, the wood pattern of this technical solution comes from chemical dyeing, so not only the authenticity of the pattern is not enough, but also the large amount of dye used pollutes the environment
