Abstract

The invention discloses a production technology of hydrophobic bamboo wood with the surface being loaded with oxidized graphene and silicon dioxide, and relates to the technical field of composite materials. The production technology includes the following steps that S1, absolute ethyl alcohol, deionized water and ammonia water are collected to be poured into a beaker for stirring, so that a soak solution is prepared, and TEOS is added into the soak solution to obtain colloid; S2, the bamboo wood loaded with the oxidized graphene and the colloid in the step S1 are transferred into a reaction still to carry out a hydrothermal reaction; S3, after the hydrothermal reaction is completed, a bamboo block is taken out and cleaned with the deionized water, and then the bamboo block is put into a vacuum drying oven to be dried; S4, heptadecafluorodecyl trimethoxy-silane and methyl alcohol are mixed to be evenly stirred, so that mixed liquor is formed; S5, the bamboo block dried in the step S3 is put into the mixed liquor of the step S4 to be stirred; and S6, after stirring is completed, the bamboo block is taken out and is washed with the methyl alcohol, and then the bamboo block is put into the vacuum drying oven to be dried so that a product can be prepared. By the adoption of the production technology, the technical problem that bamboo wood prepared in the prior art cannot meet the hydrophobic requirement is solved.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a hydrophobic bamboo material loaded with graphene oxide and silicon dioxide on the surface and a production process thereof. Background technique [0002] Bamboo is a kind of natural porous material, which has many pores of different sizes, such as cell cavity, microfibril gap, etc.; and bamboo contains many hydrophilic groups, making it easy for water to penetrate into the interior of bamboo, and it is compatible with bamboo. Some components in the bamboo are combined in the form of chemical bonds or hydrogen bonds, causing the swelling of the fibrils, thereby changing the size of the bamboo. Therefore, during the use of bamboo products, changes in the dimensional stability of the material itself are often caused by changes in the humidity in the environment, resulting in cracking and deformation of the material. Therefore, it is necessary to consider some practica...
