Embodiment 1
[0020] Step 1. Clean the montmorillonite, dry it overnight at 60°C, suspend the dried zeolite in 0.05mol / L cysteamine hydrochloride solution, the ratio of solid to liquid is 1:30, and the unit of solid to liquid ratio is g / mL, treated at 60°C for 26h, centrifuged, dried at 60°C for 12h, and ground to 20 mesh to obtain mercapto-modified montmorillonite;
[0021] Step 2: Melt 30g of high-density polyethylene particles in an open mixer, add 9.2g of vinyl distearamide and 12g of 3,3'-diallyl bisphenol A, heat up to 180°C and mix for 10 minutes to obtain a resin mixed solution;
[0022] Step 3: Add 16g of mercapto-modified montmorillonite, 1.2mL of acetone, and 0.04g of Span 60 to the resin mixture prepared in step 2, and mix for 12 minutes to obtain a casting solution;
[0023] Step 4. Put the casting solution obtained in step 3 in a vacuum drying oven at 80°C for 8 hours to mature and defoam, then scrape the film on a clean glass plate, and solidify it in 0°C absolute ethanol t...

[0025] Step 1. Clean the montmorillonite, dry it overnight at 60°C, suspend the dried zeolite in 0.05mol / L cysteamine hydrochloride solution, the ratio of solid to liquid is 1:10, and the unit of solid to liquid ratio is g / mL, treated at 90°C for 18h, centrifuged, dried at 60°C for 12h, and ground to 20 mesh to obtain mercapto-modified montmorillonite;
[0026] Step 2: Melt 50g of high-density polyethylene particles in an open mixer, add 5.4g of vinyl distearamide and 20g of 3,3'-diallyl bisphenol A, heat up to 150°C and mix for 30 minutes to obtain a resin mixed solution;
[0027] Step 3. Add 9g of mercapto-modified montmorillonite, 2.8mL of acetone, and 0.01g of Span 60 to the resin mixture prepared in step 2, and mix for 18 minutes to obtain a casting solution;
[0028] Step 4. Put the casting solution obtained in step 3 in a vacuum drying oven at 60°C for 12 hours to mature and defoam, then scrape the film on a clean glass plate, and solidify it in 0°C absolute ethanol t...
Embodiment 3
[0030] Step 1. Clean the montmorillonite, dry it overnight at 60°C, suspend the dried zeolite in 0.05mol / L cysteamine hydrochloride solution, the ratio of solid to liquid is 1:26, and the unit of solid to liquid ratio is g / mL, treated at 70°C for 24 hours, centrifuged, dried at 60°C for 12 hours, and ground to 20 mesh to obtain mercapto-modified montmorillonite;
[0031] Step 2: Melt 36g of high-density polyethylene particles in an open mixer, add 8.2g of vinyl distearamide and 14g of 3,3'-diallyl bisphenol A, heat up to 175°C and mix for 15 minutes to obtain a resin mixed solution;
[0032] Step 3. Add 15g of mercapto-modified montmorillonite, 1.6mL of acetone, and 0.03g of Span 60 to the resin mixture prepared in step 2, and mix for 14min to obtain a casting solution;
[0033] Step 4. Put the casting solution obtained in step 3 in a vacuum drying oven at 75°C for 9 hours to mature and defoam, then scrape the film on a clean glass plate, and solidify it in 0°C absolute etha...
