▎ 摘 要
NOVELTY - Self-heating eye-protecting patch of Panax notoginsengsaponins, is prepared by a graphene gel eye-protecting patch through one load, two loads, and three loads. USE - Self-heating eye-protecting patch of Panax notoginseng saponins. ADVANTAGE - The patch has excellent spontaneous thermal performance and antibacterial performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the self-heating eye- protecting patch for Panaxnotoginsengsaponins, which involves (a) Preparation of graphene gel eye patch by mixing graphene oxide and diethyl ether in a mass ratio of 1:10-1:12, placing in the reaction kettle, and place a protective film at the bottom of eye-protecting paste, reacting at 120-150℃ for 12-15 hours, taking out the eye patch mold and wash it with absolute ethanol for 3-5 times, at -10 to -5 ℃, 5-10Pa pressure and drying for 4-6 hours to prepare a graphene gel eye protection patch; (b) mixing the Panax notoginsengsaponins, pure water, and glycerin in a mass ratio 1:4:4-1:6:6 to prepare pseudo-ginseng saponin liquid, soaking the graphene gel eye-protecting paste in the Panax notoginsengsaponins liquid, standing for 1-2 hours at 20-30 ℃, taking out and drying for 4-6 hours at -10-5 ℃, 5-10Pa to obtain the once-loaded graphene gel eye-protecting paste; (c) under the dark condition, mix starch solution, iodine solution, and polyvinyl alcohol in a mass ratio of 1:2:0 1-2:3:0 1, mix evenly, fully soaking the primary loaded graphene gel eye protection patch and suspend it for 5 s without dropping liquid, and let it stand at -80--70 °C for 20-24 hours, at -10--1℃, 10-100 Pa, drying for 10-12 hours, to prepare a secondary loaded graphene gel eye patch; (d) putting far-infrared ceramic powder, allyl trimethoxysilane, absolute ethanol and pure water in mass ratio 1:1:6:6-1:1 :10:10, mix evenly, react at 20-30℃, 30-40 kHz ultrasonic for 2-3 hours, filter and wash with absolute ethanol 3 -5 times, dry at -10--5℃, 5-10 Pa for 4-6 hours, and then mix with hydrogen-containing silicone oil, chloroplatinic acid and n-hexane according to the mass ratio 1:1: 0 03:8-1:1:0 05:12 Mix evenly, at 70-80℃, Stir at 500-800 r/minute for 4-6 hours, filter and dry for 4-6 hours, Prepare the modified far-infrared ceramic powder; mix the modified far-infrared ceramic powder and n-hexane according to the mass ratio 1:5-1:8 evenly, and fully wet the paste and hang it in the air for 5 seconds until there is no dropping, dry at -10- -1℃, 10- 100 Pa for 10-12 hours, and then immerse Soak at 1-10℃ pure water and glycerin mixed in a mass ratio of 1:1 for 5-6s, take it out and vacuum seal it to obtain self-heating eye protecting patch.
