Example Embodiment
[0028] Example 1
[0029] (1) Preparation of modified montmorillonite:
[0030] Prepare nano-montmorillonite and deionized water into a suspension with a mass fraction of 1.5%, add 80% lecithin by weight of nano-montmorillonite, heat up to 70°C, fully stir for 2 hours, vacuum pump for separation, and deionize Washing with water several times, drying in an oven at 60°C for 24 hours, to obtain organically intercalated nano-montmorillonite.
[0031] (2) Preparation of nano-silver modified montmorillonite antibacterial agent
[0032] Prepare 0.8M, 10ml silver salt aqueous solution, add 2g modified montmorillonite, and disperse evenly; add 1.36g ascorbic acid as a reducing agent and 1.36g as a stabilizer polyvinylpyrrolidone, stir at 35℃ for 3 hours, vacuum pump for separation, deionized water Wash several times and dry in an oven at 60℃ for 24 hours. The antibacterial agent containing nano-silver modified montmorillonite is obtained.
[0033] (3) Preparation of silicon rubber / modified mo...
