Problems solved by technology

However, to be able to obtain the desired antibacterial film products requires a complex process, there are problems such as complex preparation and inconvenient application
In addition, there is also the problem of low dispersion of nano-silver material in polyester chips and uneven antibacterial properties
[0004] In addition, the use of chemical sterilizing agents such as hypochlorous acid and hydrogen peroxide can also eliminate the pathogenicity of microorganisms and viruses, but there are problems such as secondary pollution to the environment and stimulation to human organs
Furthermore, there is also the problem of low persistence of the effect and the inability to achieve long-term sterilization. Once the object that has just been sterilized, when the second or third person contacts it, there will be a chance of secondary infection

Abstract

The invention discloses an antiviral and antibacterial functional film and a preparation method thereof, and relates to the technical field of functional films, the functional film comprises a base material, an antiviral and antibacterial coating fixed on the upper surface of the base material, and a low-viscosity organic adhesive layer fixed on the lower surface of the base material layer; the antiviral and antibacterial coating is obtained by coating a coating solution containing a nano inorganic / organic composite antiviral and antibacterial treatment agent and transparent resin on a base material. According to the invention, a reasonable process is adopted and formula raw materials such as transparent resin and the like are reasonably selected; therefore, the nano inorganic / organic composite antiviral and antibacterial treatment agent and the transparent resin are effectively mixed to prepare a composite material which can be used for coating liquid. The antiviral and antibacterialcoating forms phase separation, and the concentration of the nano inorganic / organic composite antiviral and antibacterial treatment agent gathered on the surface is high, so that a stronger antiviraland antibacterial effect is obtained, and the antiviral and antibacterial properties are uniform and long-acting.

Description

technical field [0001] The invention relates to the technical field of functional films, in particular to an antiviral and antibacterial functional film and a preparation method thereof. Background technique [0002] In recent years, infectious diseases caused by various viruses such as new influenza, new coronavirus, Ebola, and bacteria such as Klebsiella pneumoniae have threatened human life, especially the several outbreaks caused by viral infection in the past ten years The large-scale epidemic has caused a large number of casualties and economic losses around the world, so it is urgent to find a countermeasure worldwide. From such viewpoints, there is an increasing demand for functional film materials having antibacterial and antiviral properties. [0003] As such a functional film material having antibacterial and antiviral properties, it has been reported. CN105348756B discloses an antibacterial polyester film and its preparation method and its application, which is...
