Abstract

The invention discloses fast growing wood steeping liquor, which comprises the following components in parts 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 carboxymethylcellulose, 110.0 to 150.0 parts of ammonia water, 60.0 to 70.0 parts of tripolycyanamide, 2.0 to 5.0 parts of polyvinyl alcohol and 3.0 to 6.0 parts of hexamethylene tetramine. A method for preparing the steeping liquor comprises the following steps of: adding the components into a reaction kettle according to the proportion; adding urea by three times; stirring; adjusting the pH value; and performing polycondensation reaction. A method for steeping wood with the steeping liquor comprises the following steps of: drying twice, vacuumizing and impregnating at high pressure. The process for preparing the steeping liquor is simple; the condition is mild; the steeping liquor is convenient to operate and easy to use, can be reused and is low in cost. The wood treated by the method for steeping the wood keeps the original natural properties (heat insulation and insulation) and has functions of flame retarding, corrosion prevention, antibiosis, white ant prevention, deformation prevention, environment friendliness, density and hardness adjustment and the like and is an ideal substitute for natural precious trees.

Description

technical field [0001] The invention relates to a composition of fast-growing wood impregnating liquid, a preparation method of the impregnating liquid and a process of impregnating a medicinal liquid prepared by using the impregnating liquid. 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 ...
