Embodiment 1

[0031] The used JD Express packaging corrugated boxes were crushed in a Philips HR2104 / 90 hand-held pulverizer juicer for 5 minutes into a fluffy shape, placed in a tube furnace, and carbonized at 400, 600, and 800°C for 2 hours under the protection of nitrogen to obtain Hydrophobic and lipophilic carbon materials for corrugated cardboard precursors.

[0032] The effect of different crushing and carbonization temperatures on the hydrophobic and lipophilic properties of corrugated cardboard precursor carbon materials shows that the carbon materials obtained by carbonization at 600°C after crushing for 5 minutes have the best superhydrophobic and super lipophilic properties.

[0033] figure 1 It is the water drop contact angle of the carbon material obtained by pulverizing the corrugated cardboard prepared in Example 1 and carbonizing it at different carbonization temperatures. Depend on figure 1 It can be seen that the carbon material obtained by carbonization at 600°C after ...

Embodiment 2

[0041] Put the used Jingdong Express packaging corrugated box into a Baijie BJ-150 stainless steel pulverizer for 5 minutes and pulverize it into a fluffy shape, put it in a tube furnace, and carbonize it at 600°C for 2 hours under the protection of nitrogen to obtain the corrugated cardboard precursor carbon material .

[0042] After testing, the obtained carbon material has super-hydrophobic and super-oleophilic properties.

Embodiment 3

[0044] Put the used Tmall express packaging corrugated box in the Oakes HX-PB1250 wall-breaking food processor and crush it into a fluffy shape for 5 minutes, place it in a tube furnace, and carbonize it at 600°C for 2 hours under the protection of nitrogen to obtain the corrugated cardboard precursor carbon Material.

[0045] After testing, the obtained carbon material has super-hydrophobic and super-oleophilic properties.

Abstract

The invention relates to a super-hydrophobic super-oleophylic carbon material and a preparation method thereof. The method comprises the steps that 1, corrugated boards are put into a crushing machinefor crushing; 2, the crushed corrugated boards are put into a tube furnace for carbonization treatment under the protection of inert gas, and then the super-hydrophobic super-oleophylic carbon material which takes the corrugated boards as a precursor is obtained. Compared with the prior art, the prepared carbon material has excellent super-hydrophobic super-oleophylic performance, the preparationmethod is cheap, easy to implement, and environmentally friendly, extensive application is feasible, the obtained carbon material can be conveniently sprayed onto various common bases and used for efficient high-selectivity oil-water separation, and thus the application prospects are wide.

Description

technical field [0001] The invention belongs to the technical field of material modification and adsorption of new materials, and in particular relates to a superhydrophobic and superoleophilic carbon material and a preparation method thereof. Background technique [0002] The rapid development of e-commerce and express delivery industry in recent years has completely changed people's life and shopping methods. Correspondingly, the high value-added resource utilization of corrugated cardboard express packaging is also facing new challenges. According to relevant reports released by the State Post Bureau, in 2016, the corrugated cardboard consumed by my country's express delivery service companies reached 46 million tons, which is equivalent to about 72 million trees. According to a survey conducted by the People's Daily, the actual recycling rate of corrugated cardboard in my country's express delivery industry is less than 10%, and more than 90% of the corrugated cardboard ...
