Document Type and Number:
WIPO Patent Application WO/2022/267319
Kind Code:
A1
Abstract:
A method for improving the dimensional stability of fast-growing wood by using a lignin-based modified liquor. The present invention relates to a method for improving the dimensional stability of fast-growing wood. The present invention aims to solve the problem of poor dimensional stability of existing fast-growing wood. The method comprises: 1. pretreatment of industrial lignin; 2. preparation of activated lignin; 3. preparation of a lignin-based modified liquor; 4. treatment of the wood with the lignin-based modified liquor. The present invention is used for a method for improving the dimensional stability of fast-growing wood by using a lignin-based modified liquor.
