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

Abstract

The invention discloses a wood modifying agent and a preparation method thereof, and belongs to the technical field of wood modifying agents. The wood modifying agent is prepared by the following rawmaterials in parts by weight: 5-15 parts of formaldehyde, 10-20 parts of methyl acrylate, 4-8 parts of alkyl polyglucoside, 8-12 parts of gallic acid, 2-6 parts of zinc chloride, 2-4 parts of sodium dodecyl benzene sulfonate, 20-40 parts of urea, 300-400 parts of water, and 1-5 parts of emulsifying agent. The invention further discloses the preparation method of the wood modifying agent. The woodmodifying agent is low in viscosity, excellent in water solubility, excellent in storage stability, low in formaldehyde release quantity, suitable for modification of various tree types and higher ineconomical value.

Description

technical field [0001] The invention belongs to the technical field of wood modifiers, in particular to a wood 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, the domestic timber ...
