Antibacterial melt-blown material as well as preparation method and application thereof

Abstract

The invention discloses an antibacterial melt-blown material as well as a preparation method and application thereof. Melt-blown polypropylene resin is adopted as a base material, a metal ion polymer with a large melt index is utilized, a water electret master batch formula is improved, hindered amine and stearate are adopted as organic electret agents, on the basis of formula improvement, water electret treatment is adopted, and the prepared melt-blown material not only has an antibacterial effect, but also has high filtering efficiency on tiny particles in air, and can be widely applied to preparation of antibacterial filtering materials.

Description

Technical field[0001]The present invention relates to the field of air filter materials, and more particularly to antibacterial meltblown materials and methods and methods thereof.Background technique[0002]Filter materials, generally in the air quality of the sealed environment, such as masks, etc., have a certain filtration effect. China Patent CN103520999A discloses a composite nanofiber high-efficiency air filtration material involving antibacterial and its preparation method, mainly used in mask protective masks, and protective clothing and other fields. The high-efficiency air filter material is formed by electrostatic spinning mode, including no Spinning support layer, antibacterial fiber and micron fiber blended filtration layer and nanofibrilic filtration layer, harmful gases containing bacterial viruses have a certain filtration effect while antivision is bacteria. However, this antibacterial filtering material requires additional antibacterial layer, which requires the pre...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to overcome the defects and deficiencies that the existing filter material with antibacterial effect has a multi-layer structure, and needs to be combined with the tedious electrospinning process to obtain the performance of antibacterial and high filtration efficiency. Antibacterial melt-blown materials, by improving the formula, do not need to prepare a multi-layer structure, and only need simple water electret treatment, it can simultaneously achieve the effect of anti-virus and sterilization, and have high filtration efficiency for tiny particles in the air
