Abstract

The invention provides a wood softener, wherein components included in the wood softener and the weight percentage of each component are as follows: 10-80% glycerol, 0.2-3% anionic penetrating agent, and rest being water. The invention also provides a preparation method of the wood softener, wherein the following process is adopted: proportionally and evenly mixing glycerol with anionic penetrating agent and water, and stirring the mixture using a stirrer at 25-40 DEG C and at a speed ranging from 50-200 r/min for 1-3 min. The invention further provides a method for performing softening treatment on the wood, comprising the following steps of: adding the prepared softener to a container; putting small wood pieces in the softener; and heating to a range of 70-100 DEG C and keeping the temperature for 3-10 h. The invention additionally provides a method for processing wood slices, comprising the following steps of: adding the prepared softener to the container; heating to a range of 70-100 DEG C and keeping the temperature for 3-10 h; and then putting the softened wood pieces into mixed solution of absolute ethyl alcohol and anhydrous glycerol, and oscillating for 0.5-5 hours, thereby forming the wood pieces into wood slices. The wood slice is processed by the wood softener, which is used for identifying the type of wood.

Description

technical field [0001] The invention belongs to the field of wood anatomy, and in particular relates to a wood softener and its preparation method and application. Background technique [0002] With the rapid development of my country's economy, people's living standards have improved significantly, and people are paying more and more attention to interior decoration and furniture purchases, especially for furniture made of precious wood (such as mahogany). However, it is difficult to distinguish the authenticity of precious wood in the market, and the quality of the wood is mixed. Because some miscellaneous woods and hardwoods also have the characteristics of hard wood, heavy quality, and fine texture, many merchants use "one material with many" or "one with many materials" The method is to use cheap miscellaneous wood to pretend to be all kinds of precious wood, to make high profits, and to entrap consumers. Therefore, it is necessary to make correct identification of tim...
