[0034] A preparation method of zinc-based montmorillonite aseptic band-aid, comprising the following steps:
[0035] (1) Grind zinc-based montmorillonite into fine powder, pass through a 500-mesh medicinal sieve, put it into a dry heat sterilizer, sterilize at 170-180°C, and sterilize for 180-240 minutes. Standby at room temperature;
[0036] (2) Take the hydroxypropyl cellulose of formula quantity, pulverize, pass 100 mesh medicinal sieves; Carry out sterilization in the ethylene oxide sterilization cabinet, the pressure is 35~50Kpa, and sterilization time is 3~6h, in Standby at room temperature;
[0037] (3) Take the glycerin and polyethylene glycol 1500 of formula quantity and sterilize at 121-125° C. for 30-60 minutes, transport them to sterilized tanks for storage, and store them at room temperature for later use;
[0038] (4) Put the material obtained in step (1) and step (2) into the sterilized tank in step (3) and add purified water; stir and mix evenly, and the stir...
experiment example 1
[0058] Experimental example 1: Prescription amount screening experiment
[0059] Zinc-based montmorillonite is prepared by modifying montmorillonite, which belongs to a kind of mineral medicine. Since the particles of mineral medicine are relatively thick, if there are larger particles in the preparation of band-aids, it is easy to cause secondary damage to the skin and damage the wound. Healing produces unfavorable factors, secondly if there are larger particles, uniformity problems are produced in the production coating process, for this reason the present invention designs the following prescriptions, with molding and particle size as evaluation indicators, test according to the preparation method of Example 1, and screen Test, see Table 1.
[0060] Table 1 Prescription dosage screening (parts by mass)
[0061]
[0062] Results: Prescription 1: short molding time, uneven coating, particle size less than 180μm;
[0063] Prescription 2: The molding time is slightly longe...

[0078] Experimental example 2: Zinc-based montmorillonite sterilization experiment
[0079] The active ingredient zinc-based montmorillonite of the preparation described in the present invention is modified by montmorillonite, and is a layered mineral composed of extremely fine-grained hydrous aluminosilicate. The research on the sterilization method of zinc-based montmorillonite is to ensure that the zinc-based montmorillonite On the premise that the montmorillonite band-aid drug meets the quality standards, it is a major innovation breakthrough to ensure that the zinc-based montmorillonite band-aid drug can be used safely.
[0080] The comparison of different dry heat temperatures and dry heat times on the dry heat sterilization effect of zinc-based montmorillonite is shown in Table 3:
[0081] Table 3 Zinc-based montmorillonite dry heat sterilization effect comparison
[0082]
[0083] It can be analyzed from Table 3 that:
[0084] 1. Under the conditions of dry heat t...
