Abstract

The invention relates to the technical field of wood modification, and particularly relates to a wood modifying agent with surface activity as well as a preparation method and application thereof. Thewood modifying agent with the surface activity is of a structure as shown in a formula I as shown in the specification. The wood modifying agent with the surface activity comprises flame retarding nitrogen and sulphur, a hydrophobic fat chain and a hydrophilic carboxyl, so that the hydrophily of the wood is reduced, and the shortages of low hydrophobic function and easy loss of the modifying agent are overcome; the modifying agent has the advantages of being high in flame retarding efficiency, good in smoke inhibiting effect, high in hydrophobic performance and resistant to loss, and is a multifunctional wood flame retarding agent. Additionally, the use performance and the color of the wood are not influenced after the wood modifying agent with surface activity is added to the wood. The invention also provides the preparation method of the wood modifying agent with the surface activity; the synthesis processes is simple and convenient, raw materials are easy to obtain, and the methodis easy to popularize.

Description

technical field

[0001] The invention relates to the technical field of wood modification, in particular to a surface-active wood modifier and a preparation method and application thereof. Background technique

[0002] Wood is a natural biomass material, which is widely used in construction materials, furniture products and other fields due to its light weight, high mechanical strength and excellent processing performance. However, wood is a flammable material, which is a fire hazard due to its flammability; at the same time, wood contains a large number of hydrophilic groups and its porous structure makes wood highly hygroscopic and hydrophilic, and moisture will cause wood to change color and deform , so it is necessary to modify the wood.

[0003] Among the many wood modifiers that have been reported so far, most modifiers only have one or two modification effects, and the modification effect is single. Contents of the invention
