Modifying agent used for strengthening dimensional stability of compound wax emulsion of quick-growing wood

Abstract

The invention discloses a modifying agent used for strengthening dimensional stability of compound wax emulsion of quick-growing wood. The modifying agent is prepared from the following raw materials in parts by weight: 3-3.5 parts of formaldehyde, 2-3 parts of urea, 1.5-2 parts of hexamethylenetetramine, 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 dihydroxymethyl dihydroxyl ethylene urea with solid content being 42wt%, 1.5-2 parts of magnesium chloride hexahydrate, 10-11 parts of silica sol, 3-4 parts of paraffin, 2-3 parts of microcrystalline wax, 3-4 parts of fatty alcohol-polyoxyethylene ether and 2-2.5 parts of polyvinyl alcohol. The modifying agent disclosed by the invention is good in stability, is safe and environmentally-friendly and is suitable for industrial production; impregnation pressure treatment is carried out on the quick-growing wood, so that the modifying agent can penetrate into the wood to achieve waterproof and flexible effects, and therefore, the modified wood is not liable to crack, is resistant to moisture, is good in dimension stability; and furniture manufactured from the wood is strong and durable in use, is waterproof and mildew-proof, and can be used outdoors.

Description

technical field [0001] The invention relates to the technical field of wood modification, in particular to a modifier for enhancing dimensional stability of a composite wax emulsion 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 to use artificia...

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
