Problems solved by technology

However, pure transparent wood has great limitations and cannot meet people's daily needs to a certain extent. The light energy is stored, and after the light irradiation is stopped, it is slowly released in the form of luminous light. It can still emit light at night or in the dark, and lasts for several hours to more than ten hours. It will be greatly improved in daily life applications

Embodiment 1

[0022] Embodiment 1: A kind of preparation method of luminous transparent wood, carry out according to the following steps:

[0023] a, configure 2.3mol / L sodium hydroxide solution and 0.35mol / L sodium sulfite solution, mix sodium hydroxide solution and sodium sulfite solution to obtain 1000ml mixed solution, the volume of sodium hydroxide solution in the mixed solution accounts for 18% of the total mixed solution volume, The volume of sodium sulfite solution accounts for 22% of the total volume of the mixed solution; prepare the wood and process the logs to obtain wood with a length, width and height of 25mm×20mm×5mm; then use vacuum to remove the air in the wood, and then put the wood to 333ml Boiling treatment in the mixed solution. During the boiling period, the color of the mixed solution becomes darker and then a new mixed solution is replaced. The number of replacements is 3 times, and then the wood after the boiling treatment is cleaned with deionized water;

[0024] b...

Embodiment 2

[0026] Embodiment 2: A kind of preparation method of luminous transparent wood, carry out according to the following steps: Carry out according to the following steps:

[0027] a, configure 2.5mol / L sodium hydroxide solution and 0.4mol / L sodium sulfite solution, mix sodium hydroxide solution and sodium sulfite solution to obtain 1000ml mixed solution, the volume of sodium hydroxide solution in the mixed solution accounts for 20% of the total mixed solution volume, The volume of sodium sulfite solution accounts for 20% of the total volume of the mixed solution; prepare the wood and process the log to obtain a wood with a length, width and height of 25mm×20mm×5mm; then remove the air in the wood, and then boil the wood in 250ml of the mixed solution , replace the new mixed solution after the color of the mixed solution becomes darker during the boiling period, the number of replacements is 4 times, and then clean the boiled wood with deionized water;

[0028] b. Put the cleaned ...

Embodiment 3

[0030] Embodiment 3: On the basis of embodiment 2, in step a, the described air removal in the wood is by placing the wood in deionized water, then vacuumize (0.1MPa) until the wood sinks into the deionized water . In step a, the boiled wood is boiled and cleaned with deionized water for 1 hour, and the deionized water is replaced until the pH value tends to be neutral; in step c, the impregnation is vacuum impregnation, and the pressure condition is 0.1MPa , the impregnation time is 10min, depressurize to normal pressure after impregnation, place for 3 minutes and vacuum impregnate again, repeat 3 times, and finally get the following figure 1 and figure 2 Luminous clear wood shown.

Abstract

The invention discloses a preparation method of noctilucent transparent wood. The method comprises the following steps: a, removing air in wood, then, putting the wood into a mixed solution for boiling, changing the mixed solution into a new mixed solution when the color of the mixed solution is darkened in the boiling period for 3-5 times, and then, cleaning the boiled wood with deionized water,wherein the mixed solution comprises 18-23% by volume of a 2-3 mol / L sodium hydroxide solution and 18-23% by volume of a 0.3-0.5 mol / L sodium sulfite solution; b, putting the cleaned wood into a 0.08-0.12 mol / L sodium chlorite solution, adjusting the pH to 3-5 with acetic acid, then, putting the wood into a constant-temperature water area at the temperature of 60-90 DEG C to be bleached for 3-5 h,after bleaching, cleaning the wood with deionized water, and then, putting the wood into absolute ethyl alcohol to be soaked for 8-12h in a sealed mode; and c, putting the soaked wood into impregnation liquid containing noctilucent powder to be impregnated, and after impregnation, natural drying the wood for 20-30h for curing to obtain a finished product . By means of the method, the wood has thetransparent characteristic, the noctilucent powder and the wood can be combined more conveniently, and the wood has the advantages of storing light energy and emitting light at night.

Description

technical field [0001] The invention relates to the technical field of novel luminous materials, in particular to a preparation method of luminous transparent wood. Background technique [0002] In recent years, a new type of biomass material called transparent wood has attracted widespread attention at home and abroad. Transparent wood is a polymer material with matching refractive index injected into delignified wood or modified wood with lignin retained, so as to endow it with certain optical properties and improve its mechanical properties. However, pure transparent wood has great limitations and cannot meet people's daily needs to a certain extent. The light energy is stored, and after the light irradiation is stopped, it is slowly released in the form of luminous light. It can still emit light at night or in the dark, and lasts for several hours to more than ten hours. Life applications will be greatly improved. However, there is a problem that existing wood materia...
