Description
Technical field
The utility model relates to the special-purpose overlay film nonwoven of a kind of purification PM2.5 mouth mask, especially a kind of mouth mask of the PM2.5 of obstruct particle overlay film nonwoven.
Background technology
Along with all parts of the country begin progressively to implement new Air Quality Evaluation standard, and the many provinces and cities of China have occurred continuing dense haze weather recently, make " PM2.5 " more and more become people's outline.
Because the PM2.5 particle is very large on the impact of health and atmosphere quality, the common people have shown great enthusiasm to mouth mask, but the special mouth mask that protects for this superfine particle is also few in the market, on market, the existing mouth mask overwhelming majority uses nonwoven, gauze, plastic net cloth etc. to be prepared from, they knit the hole or mesh is all larger, the particle that some are tiny or flue dust can also pass mouth mask and enter nasal cavity.
Summary of the invention
The purpose of this utility model is to solve the relative excessive PM2.5 particles that can't stop in mouth mask gap such as present common gauze, non-woven fabrics gauze mask and plastic net cloth, provide a kind of and can stop most PM2.5 particles, and ensure the smoothness of breathing, the comfortableness of wearing, allow the people breathe the special-purpose overlay film nonwoven of mouth mask of high-quality air.
Polytetrafluoroethylene (PTFE) due to the chemistry with a series of excellences and physical property, is very important a kind of engineering plastics, in a lot of fields, application is arranged, and is also a kind of important membrane material.Microporous teflon membran is except having excellent chemistry and physical property, and, the advantages such as porosity high, waterproof and breathable, wind-proof warming little due to its aperture, in fields such as chemical industry, medical treatment, clothes, electronics, important application prospect is arranged.
The polyfluortetraethylefilm film coated filter material has been widely used in the supporting sack cleaners of dust-filtering such as metallurgy, coal-burning power plant, garbage burning factory, cement plant, coal-burning boiler, makes the overlay film filter material give play to unprecedented core force aspect environmental protection just because of the good strainability of microporous teflon membran.
Technical scheme
The special-purpose overlay film nonwoven of purification PM2.5 mouth mask of the present utility model comprises two-layer nonwoven, also is provided with one deck microporous teflon membran between two-layer nonwoven.
The grammes per square metre of described nonwoven is 20～40g/m
2
The grammes per square metre of described microporous teflon membran is 1.0～4.0g/m
2, pore size is 0.1～1.0 μ m, and porosity is 80～90%, and air penetrability is 8～15cm/s.
The utility model utilizes small-bore, the high porosity of microporous teflon membran to realize taking into account and filters the PM2.5 particle and breathe smooth and easy sense, effectively realizes intercepting the purpose that the PM2.5 particle enters human body.
The preparation method of the special-purpose overlay film nonwoven of purification PM2.5 mouth mask of the present utility model: microporous teflon membran is placed between two-layer nonwoven, and hot pressing is overlying on two-layer nonwoven microporous teflon membran.
Described hot pressing temperature is 80～150 ℃.
Described hot press operation is that hot melt presses, hot pressing overlay film or utilize the eva PUR.It is all to make part fibers melt in nonwoven by heating that hot melt presses with the hot pressing overlay film, puddle plays adhesive, pass through ambient pressure, make the fibers melt part that PTFE film and nonwoven are bonded together preferably, the hot pressing film coating technique is that whole face is exerted pressure, the monoblock film is laminated with in nonwoven surface, and it is that point-like is stressed that hot melt presses, and makes between film and nonwoven to be spot bonding; The eva PUR be play substitute hot melt press with the hot pressing film coating technique in the fused fiber part, eva PUR fusing point is lower, can reduce the overlay film temperature, bonding effect is also better, and low temperature can reduce hot pressing to the infringement of PTFE film.
The filter efficiency of the special-purpose overlay film nonwoven of purification of the present utility model PM2.5 mouth mask all more than 99.97%, air penetrability is all more than 8.0cm/s, can stop most PM2.5 particles, can be used for preparation and purify the PM2.5 mouth mask, ensured simultaneously the smoothness of breathing, solve the drawback of feeling oppressed when wearing mouth mask, guaranteed the comfortableness of dressing.By the overlay film nonwoven that this preparation method makes, Acceptable life is long, prevents the effective, light and comfortable of PM2.5 particle, is worth producing and promoting.
