Embodiment 1
[0033] Weighing: 4 kg of cedarwood oil, 6 kg of chitosan, 15 kg of nano-titanium dioxide, 20 kg of nano-silver oxide, 40 kg of polyhexamethyleneguanidine hydrochloride, and 3 kg of trichlorodiphenylcarbamide. Stir and mix evenly to obtain a compound antibacterial agent.
Embodiment 2
[0035] Each raw material was weighed according to the data corresponding to Example 2 in Table 1. Mix the components uniformly in a mixer at a speed of 300-400r.p.m, mix for 5-10 minutes, then melt and knead in a twin-screw extruder, extrude and granulate, and extrude the extruded pellets at 90°C Dry it in a constant temperature oven for 9 hours, then inject it into a 50mm×50mm plastic sample at an injection molding temperature of 200-220°C, and conduct an antibacterial test. The test data are shown in Table 2. Antibacterial test standard: QB / T2591-2003A "antibacterial plastic antibacterial performance test method and antibacterial effect". Detection bacteria: Escherichia coli (Escherichia coli) ATCC25922, Staphylococcus aureus (Staphy lococcus aureus) ATCC6538.
Embodiment 3
[0037] Each raw material was weighed according to the data corresponding to Example 3 in Table 1. Plastic samples were prepared according to the method of Example 2, and then antibacterial tests were carried out.
