Abstract

The invention relates to the technical field of wood veneer modification, in particular to a modification technology capable of improving dimensional stability of a wood veneer. The preparation technology comprises the following steps: A. preparing the material: cutting the wood with a saw into wood veneers with the thickness of 2-5 mm; B. bleaching: bleaching the sawn wood veneers with a bleaching modifier; C. dyeing: dyeing the bleached wood veneers with a dyeing modifier; D. drying: drying the dyed wood veneers. The modification technology disclosed by the invention can obviously improve the dimensional stability of the wood veneer, and is simple in steps, convenient to operate and control, stable in quality, high in production efficiency and capable of realizing large-scale industrial production. The modified wood veneer prepared according to the invention is good in dimensional stability, capable of resisting against deformation and cracking, and greatly promoted in corrosion prevention, worm damage resistance, mildew prevention, waterproof performance and flame retardant property; the modified wood veneer is better in density, rigidity, bending resistance and elasticity modulus; the usability of the wood veneer can be promoted, and the service life of the wood veneer can be prolonged.

Description

technical field [0001] The invention relates to the technical field of veneer modification, in particular to a modification process for improving the dimensional stability of veneer. Background technique [0002] my country is a country that is relatively short of timber resources in the world. The forest coverage rate is only equivalent to 3 / 5 of the world's average level, and the per capita forest area is less than 1 / 4 of the world's average level. With the continuous increase of timber consumption, the contradiction between supply and demand is increasingly protrude. Statistics show that the comprehensive utilization rate of wood in my country is only about 60% at present, while developed countries have reached more than 80%, which is far below the world average. In 2005, the National Development and Reform Commission and other departments jointly issued the "Opinions on Accelerating the Promotion of Timber Conservation and Substitution Work" mentioned that in 2015, the l...
