Examples
preparation example 1-3
[0039] In Preparation Examples 1-3, the silane coupling agent was selected from Guangzhou Suixin Chemical Co., Ltd., model KH550, and the graphite oxide was selected from Nanjing Xianfeng Nano Material Technology Co., Ltd., model NF003.
preparation example 1
[0040] Preparation Example 1: Disperse 0.2kg of silane coupling agent, 2kg of graphite oxide and 5kg of water with ultrasonic wave at a power of 200W, adjust the pH to 4.5 with citric acid to obtain a graphite oxide dispersion, add 5kg of paraffin, and place in a water bath at 70°C Melt in medium, and then emulsify at 16000rpm for 30min to obtain paraffin.
preparation example 2
[0041] Preparation Example 2: Disperse 0.3kg of silane coupling agent, 4kg of graphite oxide and 8kg of water with ultrasonic power of 250W, adjust the pH to 4.8 with citric acid to obtain graphite oxide dispersion, add 8kg of paraffin, and place in a water bath at 75°C Melt in medium, and then emulsify at 17000rpm for 25min to obtain paraffin.
