Fast-growing wood modifier capable of enhancing insect and ant prevention effect by utilizing plant extracts

Abstract

The invention discloses a fast-growing wood modifier capable of enhancing the insect and ant prevention effect by utilizing plant extracts. The fast-growing wood 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 hexamethylene tetramine, 0.02 to 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 to 23 parts of dimethylol dihydroxyl ethylene urea of which the solid content is 42wt%, 1.5 to 2 parts of magnesium chloride hexahydrate, 10 to 11 parts of silica sol, 7 to 8 parts of amino silicon resin emulsion, 6 to 7 parts of yellow cinnamon leaves, 6 to 7 parts of chinaberry leaves, 15 to 16 parts of cinnamon leaves, a proper amount of absolute ethanol and 0.6 to 0.7 part of octadecoic acid. The fast-growing wood modifier disclosed by the invention is capable of improving the mechanical properties and dimension stability of a wood material, also plays a certain inhibition effect on decay caused by white ants, and realizes excellent antibacterial, moisture-proof and waterproof performances; a wood material modified by the modifier disclosed by the invention can be applied to manufacturing of outdoor wood equipment, outdoor furniture and outdoor tools and is good in durability; therefore, the modifier disclosed by the invention is capable of widening the application range of fast-growing wood.

Description

technical field [0001] The invention relates to the technical field of wood modification, in particular to a fast-growing wood modifier with plant extracts enhancing the effect of preventing insects and ants. 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 to use artif...

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
