Description
Technical field
The invention belongs to electrostatic spinning technique fields, more particularly, to a kind of waterproof haze composite material and preparation
Methods and applications.
Background technique
What the aerosol systems of the particulate matters such as dust, sulfate, nitrate in air composition caused dysopia is haze.
When condensation vapor aggravation, air humidity increase, haze will be converted into mist.The difference of haze and mist is to occur relative humidity when haze
Less, the relative humidity and in mist is very big.Haze weather is a kind of atmosphere pollution state, and haze is to suspensions various in atmosphere
The exceeded general statement of grain object content, especially PM2.5 (equivalent aerodynamic diameter is less than or equal to 2.5 microns of particulate matter,
Also become lung particulate matter, Chinese title is fine particle) it is considered as causing haze weather " arch-criminal ".
The whole nation especially Middle Eastern pollution is very serious, and primary pollutant is PM2.5, and partial size is small, opposite specific surface
Product is big, and chemical activity and adsorption capacity are strong, poisonous and harmful substances such as easy CO absorption, oxynitrides, carcinogen and in atmosphere
The middle residence time is long, conveying distance is remote, bronchus and lung is easily inhaled into and is deposited on, to cause respiratory system, angiocarpy
The diseases such as system, severely impact the health of people, or even will increase the risk of sudden death.
Close implementation: 1.CN201220664009- high water repellent filter paper-utility model, the inventive principle is close, function
Energy purposes has difference.The utility model discloses a kind of high water repellent filter paper, is mainly used for solving the problems, such as that air filter paper is moisture-proof,
Including filter layer and waterproof coating, the single side of filter layer or it is two-sided be coated with the waterproof coating, waterproof coating has good
Gas has both achieved the effect that waterproof after excessive influence, the program will not be caused to implement to the filtration resistance of filter layer, right
The performance indexes influence of filter layer is smaller, is very suitable in the filtering environment required to humidity.
2.CN201710965652- a kind of composite nano fiber haze screen window and preparation method thereof-application is open, the invention function phase
Closely, principle has difference.The invention discloses a kind of composite nano fiber haze screen window and preparation method thereof, haze screen window packets
Include screen window base, nanofiber film layer and nonwoven layer；Nanofiber film layer is deposited on nonwoven fabric surface and constitutes composite layer,
The screen window is prepared by screen window base and composite layer by the way that hot pressing is compound.The advantages of invention, is: by non-woven
Depositing nanofibers film layer realizes haze on layer of cloth, then improves the mechanics of entire screen window by screen window base in hot pressing
Intensity.
As air pollution is increasingly severe, occur a variety of haze products in the market, for example, air purifier etc.,
Air purifier only purify the air of a room except haze to reach to indoor air in the case where door and window is completely closed
Effect still closes the doors and windows for a long time so that air can not circulate, causes the consequence of indoor anoxic, door and window can make again
The effect of air purifier is had a greatly reduced quality, and air purifier can not fundamentally carry out except haze, only the air entered the room
It can respite.
Haze is removed in order to carry out purification to the air entered the room, occurs a variety of haze windows at present, it can be in a steady stream
It constantly enters indoor air and carries out purification except haze, so that the air entered the room is purified air, however, existing skill
The filter layer material waterproofing of haze window screening in art is poor, in the biggish area of some humidity, environment, in season, filtering
Layer it is affected by environment, it is easy to fail, damage, influence the service life of filter, using filter effect after the short time it is rapid under
Drop.Meanwhile in rainy season or the biggish place of humidity, such haze window screening can not prevent steam from entering the room, can not reduce room
Interior humidity.Therefore, it is necessary to design a kind of novel significantly more efficient waterproof haze material, in the haze for guaranteeing former filter layer
While effect, water-proof function is provided, is avoided in the biggish area of some humidity, environment, in season, haze filter layer is by ring
Border influences, and then improves haze effect and service life.
