Filter material containing NaCl particles as well as preparation method and application thereof

Abstract

The invention provides a sea salt-containing filter material as well as a preparation method and application thereof. The filter material comprises a base material, a first slurry layer impregnated onthe base material and a second slurry layer coating the first slurry layer. The first slurry layer is prepared from the following raw materials in parts by weight: 5-10 parts of an aroma enhancer and0.2-2 parts of an emulsifier; and the second slurry layer comprises 30-50 parts of hydrogel, 0.1-0.5 part of an adhesive, 0.6-5 parts of a bacteriostatic agent, 10-25 parts of NaCl-containing particles, 0-0.6 part of sodium bicarbonate and 1-5 parts of a stabilizer. The filter material provided by the invention contains sea salt with stronger sterilization capability, so that staphylococcus, streptococcus and the like can be effectively inhibited and killed; meanwhile, the filter material disclosed by the invention also comprises a flavor enhancing material which can emit fragrance and has the effects of refreshing and restoring consciousness. Besides, the formulas of the two slurry layers are reasonable, sea salt particles can be stably attached to the hydrogel and are not prone to falling off, and therefore a mask filter piece or a mask produced with the filter material has high quality stability.

Description

Technical field [0001] The present invention relates to the field of materials, in particular, to a filter material containing NaCl particles and a preparation method and application thereof. Background technique [0002] With the development of economy, the air pollution caused by industrial production and urban life has become more and more serious, and smog has become one of the major hazards to people's healthy breathing. Experts recommend reducing going out as much as possible in haze weather, and wearing qualified masks when going out will help human health. There are also bacteria, viruses, mycoplasma chlamydia and other microorganisms in the air, and they are usually attached to suspended particles in the air and spread along with the air flow. It may cause infectious diseases such as asthma and pneumonia in the human body, and severe cases may even die due to infection. [0003] Except for very few gauze masks currently on the market, non-woven materials are used in the ...
