Problems solved by technology

But the disadvantage is that the oil will soak into the wood and increase the weight of the wood by 50% to 70%, and the heat-treated wood has a smell of oily smoke
[0013] The above four heat treatment processes are complicated, the process conditions are harsh, the control is difficult, and the stability of product quality is difficult to guarantee. Some treatment processes also require special heat treatment media. For example, the French Rectification process requires nitrogen, and the German OHT treatment process requires oil. as a heat treatment medium
[0014] Although the dimensional stability of the wood

Abstract

The invention relates to the technical field of wood modification, in particular to a wood enhancement and corrosion prevention modification liquid and a preparation method thereof. The wood enhancement and corrosion prevention modification liquid comprises the following raw materials in parts by weight: 10-30 parts of melamine modified urea resin, 4-8 parts of dextrin, 1-5 parts of a nano modifier, 0.5-1.5 parts of a preservative, 1-5 parts of auxiliaries and 60-100 parts of water. According to the wood enhancement and corrosion prevention modification liquid, the intensity and the corrosion resistance of woods can be improved; furthermore, the insect bite, mildewing, water, flame, deformation and cracking prevention performance of the modified woods are greatly improved; the density, the hardness, the anti-bending intensity and the elastic modulus are higher, so that the use performance of the woods can be improved, and the service life of the woods is prolonged. The wood enhancement and corrosion prevention modification liquid has natural properties of heat insulation, temperature adjustment, humidity adjustment and the like, is colorful and bright and is high in physical stripe third dimension; a plate looks transparent and natural.

Description

technical field [0001] The invention relates to the technical field of wood modification, in particular to a wood-enhanced anti-corrosion modification liquid and a preparation method thereof. Background technique [0002] With the development of the country's economic construction and the improvement of people's living standards, people's demand for wood is increasing. The implementation of natural forest protection projects has made the contradiction between supply and demand of timber more prominent. In order to alleviate the contradiction between supply and demand, my country has built a large area of ​​industrial plantation. Although the artificial forest wood has the advantages of fast growth and high yield, the physical and mechanical properties of the artificial fast-growing forest wood are poor, the density is low, the material is soft, and it is easy to shrink and deform. [0003] In order to expand the application range of artificial forest timber and improve the...
