Problems solved by technology

[0003] However, the antiseptic and antibacterial agents currently used generally only have a single antiseptic and antibacterial component, and the antiseptic and antibacterial objects are relatively single. Disadvantages such as short service life
In addition, many antiseptic and antibacterial agents also have toxic side effects and environmental pollution hazards to humans and animals.

Embodiment 1

[0022] The composite antiseptic and antibacterial slow-release film of present embodiment, its raw material is as follows by weight parts (100 parts):

[0023]

[0024] All raw materials were mixed uniformly, and formed into a film by hot pressing at 120°C.

[0025] The drug sustained-release curve of the composite antiseptic and antibacterial slow-release film of the present embodiment is as follows: figure 1 As shown, within 800 hours, both the wormwood extract and the calamus extract can be released continuously, and the drug release percentage at 800 hours is only about 20%.

[0026] The anticorrosion and antibacterial properties of the compound anticorrosion and antibacterial sustained-release film of this embodiment are shown in figure 2 As shown, by comparing the photos after 7 days of black mold growth, it can be seen that the antibacterial property of this embodiment is very obvious.

Embodiment 2

[0028] The composite antiseptic and antibacterial slow-release film of this embodiment, its raw material is as follows by weight part:

[0029]

[0030] All raw materials are mixed uniformly, and formed into a film by hot pressing at 160°C.

Embodiment 3

[0032] The composite antiseptic and antibacterial slow-release film of this embodiment, its raw material is as follows by weight part:

[0033]

[0034] All raw materials were mixed evenly, and formed into a film by hot pressing at 80°C.

Abstract

The invention discloses a composite anticorrosive and antibacterial sustained-release thin film comprising the following raw material ingredients in parts by weight: 2-20 parts of gallic acid, 5-40 parts of an argy wormwood extract, 5-40 parts of a calamus extract and 20-88 parts of polycaprolactone. The three selected anticorrosive and antibacterial active components of gallic acid, the argy wormwood extract and the calamus extract are all natural plant extracts, and polycaprolactone has biodegradable properties. Therefore, the composite anticorrosive and antibacterial sustained-release thinfilm can be gradually degraded in the environment after use, can be absorbed or decomposed by the environment, has no material residue, has no post-treatment problem, and cannot pollute the surrounding environment. The method of hot pressing, 3D printing or melting blow moulding is green and environmentally friendly. The process is simple and reliable, no organic solvents or other additives are added in use, and no environmental pollution or other problems exist.

Description

technical field [0001] The invention belongs to the technical field of composite materials, in particular to a composite anti-corrosion and anti-bacterial slow-release film and a preparation method thereof Background technique [0002] With the development of society and the improvement of people's living standards, people's requirements for the quality of living environment and hygiene level are getting higher and higher. Research and development of new, efficient, non-toxic, odorless and anti-mold antibacterial agents with good antibacterial and durable performance is one of the key directions for the research and development of antiseptic and antibacterial materials. [0003] However, the antiseptic and antibacterial agents currently used generally only have a single antiseptic and antibacterial component, and the antiseptic and antibacterial objects are relatively single. Disadvantages such as short service life. In addition, many antiseptic and antibacterial agents al...
