A modifier for inorganic modified fast-growing materials prepared in a high-temperature and low-oxygen environment

Abstract

The invention discloses a modifying agent prepared in the high-temperature low-oxygen environment and used for inorganic modified fast growing wood, and belongs to the field of wood modification. A preparation method of the modifying agent comprises the steps that tetraethoxysilane, a silane coupling agent and ethanol are mixed, and an in-situ polymerization reaction is generated to generate aluminum hydroxide, magnesium hydroxide and other nanometer inorganic compounds. The quantity of a silanol group is reduced by means of nanosilicon dioxide, and the water adsorption capacity is reduced; in addition, bentonite, water, water-base resin, nano-crystalline cellulose and nano-silver are introduced, macerate and wood components generate a cross-linking polymerization reaction under the heating effect, then polymerization and curing are carried out, and a net structure is formed by the mixture, the wood and the structure; and the properties such as the physics strength and the dimensional stability are improved.

Description

technical field

[0001] The invention relates to a modifier for inorganic modified fast-growing wood prepared in a high-temperature and low-oxygen environment and a preparation method thereof, belonging to the field of wood modification. Background technique

[0002] Inorganic modified fast-growing wood refers to the in-situ polymerization reaction between wood cell wall components and inorganic modifiers without changing the original excellent properties of wood, and further forms chemical bonds to obtain modified wood with excellent properties. Due to the fact that countries around the world reduce the felling of virgin forests in order to protect the earth's environment, which limits the large-scale exploitation and use of natural forests, and the performance of fast-growing forests is poor, so the efficient production of modified wood with excellent performance has become a key issue in my country and the world in the future. Research questions for the wood processing indu...
