Embodiment 1
[0020] Embodiment 1: A two-component antibacterial and anti-mildew beautifying agent is prepared by the following method, and the contents of the following components are in weight percent. First prepare component A: the preparation of component A includes the following steps: S110: Add 72% bisphenol A epoxy resin to the reaction kettle, heat at 40-50°C, and stir for 15-20 minutes; S120: Add Bisphenol F type epoxy resin 8%, heat at 40-50°C, stir for 15-20 minutes; S130: Add 3% benzyl alcohol and 8% active diluent to the reaction kettle, heat at 40-50°C, stir for 15-20 minutes Minutes; S140: Add 4% of fumed silica, 0.6% of defoamer, 0.6% of thickener and 0.6% of functional additives to the reaction kettle, heat at 40-50°C, and stir for 15-20 minutes; S150: Add to the reaction kettle Add 0.1% of ultraviolet absorber, 0.3% of antioxidant, 0.5% of nano-immonite clay and 0.1% of graphene composite anti-virus powder into the kettle, heat at 40-50°C, and stir for 15-20 minutes; S160:...
Embodiment 2
[0022] Example 2: A two-component antibacterial and anti-mildew beautifying agent is prepared by the following method, and the contents of the following components are in weight percent.
