Problems solved by technology

[0003] In addition, researchers have found that graphene has certain antibacterial properties in previous research centers. For example, in "American Chemical Society-Nano" (ACS-Nano, 2010, Vol. 4, p. Graphene paper has certain antibacterial properties, and then a series of graphene / silver nanocomposite antibacterial materials with good antibacterial properties appeared. The specific parts of the surface cannot be evenly distributed on the surface, thereby affecting the antibacterial effect; at the same time, nano-silver and graphene cannot be tightly combined, especially when the content of nano-silver particles increases, it is easy to agglomerate and fall off during use, thus affecting Service life and antibacterial effect
[0004] In previous studies, it was found that graphene has certain antibacterial properties, and then a series of graphene / silver nanocomposite antibacterial materials with good antibacterial properties appeared. The research found that the preparation process of such materials has certain complexity or The use effect has certain limitations

Embodiment 1

[0076] The present embodiment provides the preparation method of modified porous graphene antibacterial powder, comprises the steps:

[0077] Step 1. Accurately weigh 10g of modified porous graphene oxide and 80% antibacterial plant extract with a mass ratio of 20%, wherein the antibacterial plant extract is Camellia oleifera seed oil configured according to the mass percentage example 1:1 Composition with aloe vera oil, set aside.

[0078] Step 2: Add surfactant to deionized water and stir evenly, then add camellia oleifera seed oil and aloe vera oil composition sequentially, heat up to 60-90°C, continue stirring for 5-25min to obtain a mixed solution. in:

[0079] In this step, the amount of deionized water ranges from 100% to 600% of the amount of modified porous graphene oxide.

[0080] In this step, the surfactant is sodium lauryl sulfate, sodium dioctyl succinate sulfonate, sodium dodecylsulfonate, sodium dodecylbenzenesulfonate, sodium deoxycholate, sodium cholate On...

Embodiment 2

[0087] Accurately weigh 35g of modified porous graphene oxide, 25% of Camellia oleifera seed oil 25g, 5% of 5% lanthanum stearate, and obtain the antibacterial plant extract loaded on the surface according to the preparation method of Example 1 Modified porous graphene antibacterial powder composed of organic rare earth salt.

Embodiment 3

[0089] Accurately weigh 21g of modified porous graphene oxide with a mass ratio of 42%, 27.5g of 55% camellia seed oil and tea polyphenol composition, and 1.5g of 3% cerium laurate. The phenolic composition is configured according to the mass percentage example 1:1, and the modified porous graphene antibacterial powder of the composition obtained by the preparation method of Example 1 is loaded with antibacterial plant extract and organic rare earth salt.

[0090] In the present embodiment and embodiment 2, although the surface of the modified porous graphene oxide has a large number of active hydrophilic functional groups such as carboxyl groups, hydroxyl groups and epoxy bonds, the modified porous graphene oxide has strong hydrophilicity, However, its dispersibility has not been significantly improved, and the rare earth ions themselves have excellent chemical activity, and the chemical activity of the rare earth elements in the organic rare earth salt added in this embodimen...

Abstract

The present invention relates to a kind of highly antibacterial gas permeable film, it is the PE antibacterial gas permeable film formed by the modified porous graphene composite antibacterial material evenly distributed in it in PE matrix material, and its component and parts by weight are as follows: PE 40-70 parts 0.5-10 parts of modified porous graphene antibacterial masterbatch; 28-55 parts of inorganic filler; 0.5-5 parts of auxiliary agent A. Wherein, the modified porous graphene masterbatch is made of 5-60 parts of carrier resin, 1-12 parts of modified porous graphene antibacterial powder, auxiliary agent B, and is extruded and granulated by screw after blending. The pores of porous graphene are loaded with antibacterial plant extracts, or antibacterial plant extracts and antibacterial materials prepared by loading organic rare earth salts, wherein the antibacterial plant extracts are such as camellia oil, tea polyphenols, and aloe oil. Porous graphene is one or both of porous graphene oxide and porous reduced graphene, and the inorganic filler is CaCO3 or / and Na2SO4.

Description

technical field [0001] The invention relates to the technical field of disposable sanitary materials, in particular to a breathable membrane with high antibacterial properties. Background technique [0002] Graphene refers to a single layer of carbon atoms tightly packed into a two-dimensional honeycomb structure, which is the basic unit for constructing other dimensional carbon materials (such as zero-dimensional fullerenes, one-dimensional carbon nanotubes, and three-dimensional graphite). Single-layer graphene has a large specific surface area, excellent electrical and thermal conductivity and low thermal expansion coefficient. In particular, its high conductivity, large specific surface properties and its monolayer two-dimensional nanoscale structural properties can be used as electrode materials in bipolar plates of fuel cells, supercapacitors and lithium-ion batteries. [0003] In addition, researchers have found that graphene has certain antibacterial properties in p...
