Loss-resistant and permeable composite fast-growing wood modifying agent

Abstract

The invention discloses a loss-resistant and permeable composite fast-growing wood modifying agent. The fast-growing wood modifying agent 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 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, 3 to 4 parts of sucrose, 2 to 3 parts of alums, 2 to 3 parts of mannitol, 5 to 6 parts of hydrogen peroxide with the concentration of 10wt%, 1 to 1.2 parts of flakelike sodium hydroxide, 0.8 to 1 part of polyvinylpyrrolidone, 6 to 7 parts of bentonite, and 0.8 to 1 part of secondary alcohol ethoxylate. According to the fast-growing wood modifying agent, the penetrating quality is excellent, the compressive strength, abrasion resistance and toughness of the wood can be improved, the wood can maintain clear texture, and products like outdoor furniture and wooded equipment manufactured through the treated fast-growing wood are solid and durable.

Description

technical field [0001] The invention relates to the technical field of wood modification, in particular to a composite fast-growing wood modifier that is resistant to loss and easy to permeate. 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 artificial fast-grow...

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
