AI Technical Summary

Problems solved by technology

Modification liquid types include unsaturated olefin monomers, prepolymers, urea-formaldehyde resins, phenolic resins, sugar alcohol resins, resorcinol resins, acetyl agents, etc.; but most of these modification liquids have single modification, pollute the environment, The process is complex, resulting in the loss of chemicals after modification. Therefore, it is necessary to develop a wood modification solution that can not only improve the performance of wood, but also effectively use wood, prolong the service life of wood, and convert low-grade wood into high-grade wood. has important practical significance

Description

technical field [0001] The invention belongs to the technical field of wood antiseptic modifiers, in particular to a wood antiseptic modifier and a preparation method thereof. Background technique [0002] Timber is the only renewable building material resource among the four major building materials recognized in today's society, and it appears in almost all walks of life. With the development of human civilization, wood products are inseparable from various industries such as papermaking, furniture, packaging, and automobile industries. The consumption of timber is increasing, and my country has changed from a country with large forest reserves to a large importer of timber, and the gap in domestic timber demand is increasing day by day. In order to alleviate this contradiction between supply and demand, the state has proposed a plan for the construction of fast-growing and high-yield forests. However, with the increase of the area of ​​fast-growing and high-yield forests...
