Silver-loaded zirconium sodium phosphate antibacterial enhanced hydrophobic modifying agent for fast-growing wood

Abstract

The invention discloses a silver-loaded zirconium sodium phosphate antibacterial enhanced hydrophobic modifying agent for fast-growing wood. The hydrophobic modifying agent is prepared from, by weight, 3-3.5 parts of formaldehyde, 2-3 parts of urea, 1.5-2 parts of hexamine, 0.02-0.03 part of maleic anhydride, a proper amount of acetic acid, a proper amount of ammonia water, a proper amount of deionized water, 20-23 parts of dimethylol dihydroxy ethylene urea with the solid content of 42 wt%, 1.5-2 parts of magnesium chloride hexahydrate, 10-11 parts of silica gel, 0.6-0.7 part of sodium hexametaphosphate, 1.5-2 parts of silver nitrate, 6-7 parts of hydroxyl sodium zirconium phosphate, 2-3 parts of zinc nitrate, a proper amount of a saltpeter solution at the concentration of 1 mol / L, a proper amount of a sodium hydroxide solution at the concentration of 1 mol / L and 3-4 parts of polytetrafluoroethylene emulsion. The mechanical performance of fast-growing wood treated with the hydrophobic modifying agent can be improved, and fast-growing wood treated with the hydrophobic modifying agent becomes hydrophobic from the property of easy water absorption, is lasting in antibiosis and is very suitable for manufacturing outdoor wood instruments, outdoor leisure furniture and the like.

Description

technical field [0001] The invention relates to the technical field of wood modification, in particular to a silver-loaded sodium zirconium phosphate antibacterial and enhanced hydrophobic modifier for fast-growing wood. Background technique [0002] As an important means of production in social and economic construction, wood and wooden materials are not only widely used in various fields in daily life, but also widely used in industrial fields such as transportation, construction and aerospace. With the increasing shortage of forest resources worldwide, especially the sharp decline in the number of precious wood, a large number of fast-growing tree species have been widely planted to meet the global wood supply in recent years. Compared with natural forest trees, fast-growing tree species are limited by factors such as short growth years, resulting in great differences between early and late wood, loose materials, and poor mechanical properties. Therefore, it is difficult ...

AI Technical Summary

Problems solved by technology

Although the mechanical properties of the modified fast-growing wood have been improved, the application of the fast-growing wood in the field of outdoor furniture and outdoor wood equipment has been affected due to its insufficient water absorption. It also hopes to have other additional properties to meet the demand for fast-growing wood such as outdoor furniture
