Problems solved by technology

Among them, organic antibacterial agents have the advantage of quick sterilization effect, but because most organic antibacterial agents are small molecular compounds, they have disadvantages such as poor heat resistance, easy failure after aging, and easy precipitation from polymer materials after long-term storage.
[0004] Patent application CN103146119A provides a wear-resistant and antibacterial ABS modified material and its preparation method, wherein nano-silver and nano-titanium dioxide ions are added, and a layer of titanium dioxide film is formed on the surface of the ABS material by using a plasma sputtering process. Secondary machining is performed, increasing machining complexity and cost
Patent application CN107011639A discloses an antibacterial polymer material prepared by modifying nano-copper, nano-zinc, nano-silver, and modifiers, but this solution has slightly higher requirements for the preparation process of antibacterial masterbatch and the actual continuous antibacterial effect is poor
Therefore, effective materials suitable for air conditioner filter screens that can simultaneously satisfy the functions of killing bacteria and viruses have not yet been proposed.

Abstract

The invention provides an antibacterial and antiviral high polymer material, an obtained air conditioner filter screen and an air conditioner, belongs to the technical field of high polymer materials, and can solve the technical problem that an existing high polymer material cannot meet the dual functions of killing bacteria and viruses at the same time. The antibacterial and antiviral high polymer material comprises the following components in parts by weight: 100 parts of a high polymer material, 0.3-5 parts of an antimicrobial additive, 0.1-3 parts of a dispersant and 1-3 parts of an antioxidant, and the antimicrobial additive is metal oxide fibers loaded with nano-silver particles. The material can be applied to preparation of the air conditioner filter screen, and 99.9% of target viruses and bacteria can be effectively removed.

Description

technical field [0001] The invention belongs to the technical field of macromolecular materials, and in particular relates to an antibacterial and antiviral macromolecular material, an air conditioner filter net and an air conditioner obtained therefrom. Background technique [0002] The air conditioner is an adjustment device for indoor air temperature, humidity, gas composition, etc., and the filter screen of the air conditioner is a necessary component for indoor air. In daily life, a considerable part of harmful bacteria, fungi and viruses exist and multiply in the indoor air, and cause various diseases through contact. The existing filter technology mainly focuses on degrading and filtering organic molecules such as suspended particulate matter and formaldehyde in the air, and pays insufficient attention to the prevention and control functions of bacteria, fungi and viruses. [0003] As people's awareness of health continues to increase, there is a demand for "antibact...
