Description
Technical Field
The invention relates to the technical field of anti-fog masks, in particular to an anti-fog mask based on polypropylene modification and a preparation method thereof.
Background
The mask is a sanitary article, generally refers to a device which is worn at the mouth and nose part and used for filtering air entering the mouth and nose so as to prevent harmful gas, smell and spray from entering and exiting the mouth and nose of a wearer, and is made of gauze or paper and the like. The mask has a certain filtering function on air entering the lung, and has a very good effect when being worn in respiratory infectious diseases and working in environments polluted by dust and the like. The mask may be classified into an air filtering type mask and an air supplying type mask. The harmful bacteria in the air are ubiquitous, including diplococcus, monosococcus, sarcina, tetracoccus, staphylococcus and the like, have high reproduction speed, strong viability and wide spread range, and cause a plurality of diseases such as influenza, tuberculosis, measles, mumps, pertussis, diphtheria and the like when being spread in the air, and have strong infectivity and harmfulness.
Haze weather is an atmospheric pollution state, and haze is a general expression for exceeding the content of various suspended particulate matters in the atmosphere. Along with the deterioration of air quality, haze weather phenomenon appears increasing, and the harm aggravates. In many areas of China, haze weather phenomena are combined into fog to be used as early warning and forecast of disastrous weather. Collectively referred to as "haze weather". The chemical composition of haze is also complex and may cause a variety of diseases. Meanwhile, viruses, germs, etc. may be attached to the particulate matter in the atmosphere to spread diseases. PM2.5 (particles with an aerodynamic equivalent diameter of 2.5 microns or less) is considered to be the most harmful particles to the human body in atmospheric pollutants, namely the inhalable particles, because the particles with the aerodynamic equivalent diameter of 2.5 microns or less are regarded as the particles causing haze weather. The monitored PM2.5 in various regions often exceeds the standard seriously.
While the common polypropylene non-woven fabric mask has insufficient effects on resisting influenza virus, bacteria and inhalable particles, the medical mask is high in price and is inconvenient for daily use of people.
