Abstract

The invention discloses enhanced high-temperature heat treated wood and a manufacturing method thereof. The manufacturing method comprises the following steps that 1, high-temperature heat treatment is performed, wherein man-made forest wood serves as raw materials, and high-temperature heat treatment is performed on the man-made forest wood to obtain heat treated wood; 2, impregnation enhancing treatment is performed, wherein the heat treated wood obtained by the step 1 is impregnated in resin adhesives to obtain impregnated wood; 3, solidification forming treatment is performed, wherein solidification forming treatment is performed on the impregnated wood obtained by the step 2 to obtain the enhanced high-temperature heat treated wood. According to the manufacturing method, not only can the mechanical properties of the wood be improved, but also the size stability of the wood can be improved, green and environmental protection are achieved, and the prepared enhanced high-temperature heat treated wood takes the man-made forest wood as the raw materials and is high in mechanical strength and good in size stability.

Description

technical field

[0001] The invention belongs to the category of wood function improvement in the field of wood processing, and in particular relates to an enhanced high-temperature heat-treated wood and a manufacturing method thereof. Background technique

[0002] The basic principle of wood heat treatment is to use the temperature condition of 160-260 ℃ to treat wood for a certain period of time, the wood cell wall material will undergo pyrolysis and molecular structure recombination, and the wood components will undergo permanent chemical changes, so that the hygroscopicity of the treated wood will be reduced and the size will be stable. It is suitable for outdoor floors, outdoor decorative wall panels, garden furniture, wooden fences, etc. On the other hand, wood heat treatment will lead to a decrease in the mechanical strength and weight of the wood, which has become its main disadvantage.

[0003] The commercial application of wood heat treatment technology mainly start...
