Novel antibacterial and antiviral composition and treatment process thereof

Abstract

The invention provides a novel antibacterial and antiviral composition and a treatment process thereof. The surface of a treated product has quick and lasting antibacterial and antiviral functions. Meanwhile, the composition can resist high temperature of 170 DEG C and ultraviolet light irradiation for a long time, and still keeps antibacterial and antiviral functions. The composition does not irritate the skin, and has wide killing and inhibiting effects on infection or pathogenic gram-positive bacteria, escherichia coli, staphylococcus aureus, candida albicans, fungi, influenza viruses (suchas H1N1/H3N2 and the like), yeast, viruses (such as hepatitis A, hepatitis B, rabies viruses and HIV) and the like. The antibacterial and antiviral process provided by the invention can be widely applied to textiles, engineering plastic plastics (ABS/PC/POM/TR90/nylon/TPE/TPU/silica gel/rubber), glass, leather and the like.

Description

technical field [0001] The invention relates to the technical field of antibacterial and antiviral surface treatment, in particular to a novel antibacterial and antiviral composition and its treatment process. Background technique [0002] With the increasing popularity of smart terminal devices, electronic devices with display screens are used more and more frequently in daily life. In order to avoid damage to the display screen of electronic equipment due to bumping or scratching, people usually stick a protective film on the surface of the display screen. , the above solution well solves the shortcoming that the display screen is easy to be scratched. However, studies in recent years have found that the high frequency of use of electronic products will inevitably adhere to bacteria, especially some bacteria are infectious and pathogenic, such as Staphylococcus aureus; electronic equipment cannot be cleaned, and long-term accumulation will only Make the bacteria accumula...

Problems solved by technology

The silver salt is immobilized in the protective film, and its release rate is similar to that of the isothiazolinone compound in the previous scheme, which cannot be precisely controlled, so it cannot achieve a durable antibacterial effect. In order to uniformly coat the mixed solution containing the powder On the surface of the protective film and to ensure the amount of coating, the mixed solution needs to be diluted to a certain range, the proportion of silver powder is relatively large, the distribution in the mixed solution is uneven, and some silver powders will fall off.

The general solution is to load it on a carrier with better dispersion, or coat the coupling agent on the surface of the silver powder, but the loaded material will affect the light transmittance of the protective film to varying degrees.

[0004] In the prior art, most of the spraying, electroplating, soaking and other related processes are used to add antibacterial ion groups such as antibacterial compounds or silver ions on the surface of the product. The antibacterial effect cannot last long, and the antibacterial ions and unstable compounds are easy to fall off and attenuate, and the validity period is short.

The antibacterial process is unstable and not environmentally friendly, and the range of products used is limited. For example, it is difficult to do antibacterial and antiviral treatment on the surface of elastic products such as rubber
