A kind of production method of antique wood

Abstract

The invention relates to a production method of antique wood. The method includes: (1) wood selection: selecting wood with a moisture content of 6-25%; (2) color change treatment: putting pre-treated wood into a sealable container divided into an upper space and a lower space that are communicated by a hole, placing wood on the upper part, then introducing ammonia water of certain concentration into the lower space of the container, observing the color change of the inner wood, pumping out the ammonia water from the container when the color change meets the requirement, collecting and storing the ammonia water, and taking out the wood; (3) antique treatment: coating the wood surface with a mixed solution of nitric acid and potassium chlorate by a bristle brush, then using a damp cloth to wipe the surface, coating the wood surface with a 0.5% potassium permanganate solution, then applying a sodium sulfite saturated solution, and wiping the surface with a clean damp cloth; and (4) aging treatment: aging the withdrawn antique wood. The antique wood made by the invention has uniform color, good antique effect, and deep treatment depth.

Description

technical field [0001] The invention relates to a method for producing antique wood, more specifically, the invention relates to a method for producing antique wood by using an air film method. Background technique [0002] Many ancient buildings and furniture are wooden structure products. The main material is wood. These wooden structure products have been damaged to varying degrees after long-term use and need to be repaired. If the wood used for repairs is not treated , will lead to great contrast in the repaired parts and affect its effect. CN1043462A discloses Yang Bin's "wooden product surface antique treatment process", which is to place the wood that has been boiled, cleared of impurities, dried, and shaped on a metal grid that can be heated evenly and resistant to high temperatures, and heated at 800-1200 ° C. The high-temperature flame is 1-10cm away from the surface of the wood board, and burns the wood surface with fire quickly and evenly within 0.5-1 second, a...

The above two methods are based on burning the wood surface with a flame in a short period of time to make the surface partially charred and change color, and then polish it. Although these two treatment methods are relatively simple and easy to operate, the processing The depth is thin, the difference between the same batch is large, and the wood is heated on one side, so it is easy to deform
