Embodiment 1
[0029] A reinforced foam system based on synergistic stabilization of graphite particles, made of the following components in mass concentration percentages: sodium lauryl sulfate 0.6%, cetyltrimethylammonium bromide 0.4%, 200 mesh flake graphite particles 1% , make up to 100% with water.
[0030] A method for preparing a strengthened foam system based on the synergistic stabilization of graphite particles, comprising:
[0031] Step 1: Prepare 500ml of sodium lauryl sulfate aqueous solution with a mass concentration of 0.6%, add 5g of 200-mesh flake graphite particles to the solution, and disperse for 2 hours with an ultrasonic power of 500W;
[0032] Step 2: centrifuge the solution obtained in step 1 at 1500 g for 15 min, and take 100 ml of the upper graphite dispersion;
[0033] Step 3: Add 0.4 g of cetyltrimethylammonium bromide to 100 ml of graphite dispersion, stir magnetically for 1 hour, and let stand to obtain a foaming liquid;
[0034] Step 4: Stir at 8000 rpm for 3...
Embodiment 2
[0036] A reinforced foam system based on synergistic stabilization of graphite particles, made of the following components in mass concentration percentages: sodium lauryl sulfate 0.6%, cetyltrimethylammonium bromide 0.4%, 200 mesh flake graphite particles 1% , make up to 100% with water.
[0037] The preparation method of the enhanced foam system based on the synergistic stabilization of graphite particles is the same as that of Example 1 except that nitrogen is used as the gas source during the stirring process using the Waring Blender method.
Embodiment 3
[0039] The reinforced foam system based on the synergistic stability of graphite particles is made of the following components in mass concentration percentages: fatty alcohol ether sodium sulfate 0.7%, cetyltrimethylammonium bromide 0.5%, 200 mesh flake graphite particles 1%, Water topped up to 100%.
[0040] The preparation method of the enhanced foam system based on the synergistic stabilization of graphite particles is the same as that of Example 1.
