specific Embodiment approach 1

[0032] Embodiment 1: The preparation method of a kind of fluorescent transparent magnetic wood described in this embodiment is specifically carried out according to the following steps:

[0033] 1. Wood delignification:

[0034] Immerse wood with a thickness of 0.1mm-20mm into a reactor filled with a sodium hypochlorite solution with a concentration of 0.1mol / L-10mol / L to obtain a reaction system, then add glacial acetic acid to adjust the pH of the reaction system to 1-7, and seal the reaction Put the reactor at a temperature of 70°C to 200°C, cook for 1h to 52h, cool to room temperature, and then add hydrogen peroxide with a concentration of 0.1mol / L to 10mol / L into the reactor. Under the condition of ℃~200℃, continue cooking for 1h~52h, cool to room temperature, take out the reacted wood, and under the condition of 50℃~200℃, vacuum dry the reacted wood for 1h~52h to obtain Lignin wood;

[0035] The volume ratio of the hydrogen peroxide having a concentration of 0.1mol / L t...

specific Embodiment approach 2

[0055] Embodiment 2: This embodiment is different from Embodiment 1 in that the wood described in step 1 is coniferous or broad-leaved. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0056] Specific embodiment three: the difference between this embodiment and one of specific embodiment one or two is: step 2 described in 4. contains Fe 3+ The salt of ferric chloride, ferric sulfate or ferric nitrate; Step 2 described in 4. contains Fe 2+ The preferred salt is ferrous chloride, ferrous sulfate or ferrous nitrate. Others are the same as in the first or second embodiment.

Abstract

The invention relates to a manufacturing method for fluorescent transparent magnetic wood. The manufacturing method for the fluorescent transparent magnetic wood aims to solve the problems that existing wood is not transparent and does not have magnetism or the fluorescence property. The manufacturing method for the fluorescent transparent magnetic wood comprises the steps that firstly, lignin of wood is eliminated; secondly, fluorescent magnetic nanoparticles are prepared; and thirdly, the fluorescent transparent magnetic wood is manufactured and obtained. The method is used for manufacturing the fluorescent transparent magnetic wood.

Description

technical field [0001] The invention relates to a preparation method of fluorescent transparent magnetic wood. Background technique [0002] As an industrial and domestic material, wood is closely related to national economic construction and human life, and has many excellent qualities. However, wood, as a biomass material, does not have transparency, magnetism and fluorescent properties. Nowadays, with the development of material science, materials with single functions can no longer meet the requirements of social production. Multifunctional and new biomass materials are increasingly showing broad application prospects, and have attracted the attention of scientific researchers around the world. Contents of the invention [0003] The invention solves the problems of opaque, non-magnetic and non-fluorescent properties of existing wood, and provides a preparation method of fluorescent transparent magnetic wood. [0004] A preparation method of fluorescent transparent ma...
