Fast growing wood compound modifier capable of enhancing light aging resistance

Abstract

The invention discloses a fast growing wood compound modifier capable of enhancing light aging resistance. The fast growing wood compound modifier is prepared from the following raw materials in parts by weight: 3 to 3.5 parts of formaldehyde, 2 to 3 parts of urea, 1.5 to 2 parts of hexamethylenetetramine, 0.02 to 0.03 part of maleic anhydride, a proper amount of acetic acid, a proper amount of ammonium hydroxide, a proper amount of deionized water, 20 to 23 parts of DMDHEU of which the solid content is 42wt%, 1.5 to 2 parts of magnesium chloride hexahydrate, 10 to 11 parts of silica sol, 2 to 3 parts of cordierite, 6 to 7 parts of a titanium dioxide solution, 0.8 to 1 part of hexadecyltrimethoxysilane, 0.3 to 0.4 part of stearic acid and 3 to 4 parts of nano zinc oxide. According to the fast growing wood compound modifier, the raw materials are simple, the components are safe, the technology is applicable to scale production, a prepared product can improve the mechanical property of the fast growing wood, the light aging resistance of the wood is improved, the service life of the product is prolonged, and the modified wood can be comparable with valuable wood and can be used for manufacturing of outdoor furniture.

Description

Technical field [0001] The invention relates to the technical field of wood modification, in particular to a composite modifier for fast-growing wood with enhanced light aging resistance. 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 of daily life, but also widely used in industrial fields such as transportation, construction and aerospace. With the increasing shortage of forest resources in the world, especially the sharp decrease in the amount of precious wood, a large number of fast-growing tree species have been widely planted in recent years to meet the global supply of wood. Compared with natural forest trees, fast-growing tree species are restricted by factors such as short growth years, resulting in large differences in early and late wood, loose texture, and poor mechanical properties. Therefore, it is difficult to use artificial fast-growing fore...

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
