Problems solved by technology

"A method for preparing flexible transparent nano-paper by using bamboo fiber" (CN 103757986A) uses bamboo fiber to swell by adding sodium hydroxide, removes lignin with acetic acid and sulfuric acid, and then bleaches, nano-fibrillates, and papers into transparent nano-paper. Paper, which is very thin, and the process is complicated, and the method is very different from the present invention
"Preparation method of transparent wood" (CN106243391A) Treat thin wood with pure water, biological enzyme, glacial acetic acid and hydrogen peroxide mixture, then rinse with deionized water, then extract with hydrogen peroxide and ammonia water, rinse with deionized water, and then use pure Ethanol, a mixed solution of ethanol and acetone, pure acetone extract and dehydrate, and finally inject the polymer into the wood to obtain transparent wood. The process of this method is very complicated, and it is quite different from this method.
"A preparation method for fluorescent transparent magnetic wood" (CN 106313221A) solves the problems of opaque, non-magnetic and non-fluorescent properties of existing wood. Disperse into polymethyl methacrylate or epoxy resin, and fill the resin into wood under vacuum conditions to prepare fluorescent transparent magnetic wood

Embodiment 1

[0024] Cut the bamboo into slices with a thickness of 1 mm, put the bamboo slices in a sodium hydroxide solution with a mass concentration of 0.3%, heat to 100°C for 120 minutes, take them out, wash them with clean water, and soak them in absolute ethanol for 8 hours , during which the absolute ethanol was replaced once, and finally the bamboo slices were soaked in pure tung oil for 3 days, taken out, dripped off the excess tung oil on the surface, and dried in the shade to obtain yellow-brown light-transmitting bamboo slices.

Embodiment 2

[0026] Cut the bamboo into slices with a thickness of 0.1 mm, place the bamboo slices in a sodium metabisulfite solution with a mass concentration of 0.5%, heat to 60°C for 60 minutes, take them out, wash them with water, and soak them in absolute ethanol for 4 hours. During this period, the absolute ethanol was replaced once, and finally the bamboo slices were immersed in pure tung oil for 1 day, taken out, and the excess tung oil on the surface was dripped off and dried in the shade to obtain reddish-brown light-transmitting bamboo slices.

Embodiment 3

[0028] Cut the bamboo into bamboo slices with a thickness of 2 mm, place the bamboo slices in a solution of sodium hydroxide + sodium sulfide with a mass concentration of 1% (the mass ratio of the two is 3.5:1), heat it to 100°C for 90 minutes, take it out and use it Rinse with clean water, then soak in absolute ethanol for 24 hours, replace the absolute ethanol twice during the period, and finally soak the bamboo slices in pure tung oil for 3 days, take it out, drip off the excess tung oil on the surface, and dry in the shade to obtain a reddish-brown translucent Bamboo slices.

Abstract

The invention discloses a preparation method of a light transmission bamboo sheet. The preparation method of the light transmission bamboo sheet includes the steps that after the outer green and the yellow of a bamboo material are removed and the bamboo material is made into the bamboo sheet, a chemical agent is adopted for processing so that part of lignin, cell inclusion and other substances inthe bamboo sheet are removed; and then after cleaning by clean water, the bamboo sheet is sequentially soaked in absolute ethyl alcohol and dipped in tung oil, and the light transmission bamboo sheetis obtained. The light transmission bamboo sheet obtained through the method has good light transmission performance, the fiber texture of the bamboo material is reserved, a unique decoration effect is achieved, and the light transmission bamboo sheet can be used for manufacturing a bamboo lampshade, a bamboo fan, a bamboo curtain and other indoor decorative articles.

Description

technical field [0001] The invention belongs to the technical field of bamboo and wood material processing, and in particular relates to a preparation method of light-transmitting bamboo chips. Background technique [0002] my country is rich in bamboo resources, and the bamboo forest area, bamboo species and economic utilization level rank first in the world, and it is known as the "Kingdom of Bamboo". There are about 100 genera and more than 1,200 species of bamboo in the world. In my country, there are 39 genera and more than 500 species. Among them, 16 genera and more than 200 species have been cultivated and utilized because of their high economic and ecological value. Bamboo is a natural fast-growing material that has a similar texture to wood, and my country is rich in bamboo resources. Rational development and utilization of bamboo building materials can alleviate the contradiction between domestic timber supply and demand, and has very important economic, social and...
