Abstract

The invention relates to impregnation liquid for fast growing wood. The impregnation liquid is prepared from the following raw materials in part by mass: 970.0 to 1,050.0 parts of formaldehyde, 590.0 to 650.0 parts of urea, 0.7 to 1.0 part of sodium carboxymethyl cellulose, 110.0 to 150.0 parts of ammonia water, 60.0 to 70.0 parts of melamine, 2.0 to 5.0 parts of polyvinyl alcohol and 3.0 to 6.0 parts of hexamethylene tetramine. The wood treated by the impregnation liquid also has flame retardance, corrosion resistance, antibacterial property, termite resistance, deformation resistance, environment friendliness, adjustable density and hardness and the like while the original natural attributes (thermal insulation and insulation) of the wood are kept, and becomes an ideal substitute of natural precious tree species.

Description

technical field [0001] The invention relates to the composition and proportion of an impregnating solution for optimizing the properties of fast-growing wood, and belongs to the technical field of wood processing. Background technique [0002] With the rapid development of economy and society, the demand for natural forest timber at home and abroad shows a rapid growth trend. In recent years, with the improvement of environmental protection awareness in all countries in the world, austerity policies have been implemented on timber exports, which further restricts the export of natural timber and further aggravates the tense situation of timber demand. The development of substitute materials for natural forest timber is an important way to alleviate the current tension between supply and demand of natural forest timber, and it is also an inevitable requirement for building a conservation-oriented society. Fast-growing and high-yield forests are currently very rich forest res...
