The utility model belongs to the technical field of dustproof screen window manufacturing, and particularly relates to composite screen window cloth for a screen window for purifying PM2.5. The composite screen window cloth is of a five-layer structure which comprises an outer screen layer, a first non-woven fabric layer, a PTFE (polytetrafluroethylene) microporous film layer, a second non-woven fabric layer and an inner screen layer from outside to inside in sequence. The composite screen window cloth for the screen window plays a significant role in purifying indoor PM2.5, sterilizing and improving the air quality. The composite screen window cloth has the advantages of having a good dustproof effect, a good indoor PM2.5 purifying effect and a good mosquito and fly preventing effect, a certain degree of sterilization, good mechanical strength and the like.
Description
Technical field
The utility model belongs to dustproof screen window and makes material technology field, particularly relates to a kind of PM2.5 of purification screen window composite window screen cloth.
Background technology
The raising of industrial expansion and living standards of the people in recent years, quality of air environment day condition more under, there is lasting severe haze weather in many provinces and cities of China's autumn and winter in 2013 especially, PM2.5 concentration " quick-fried table " phenomenon occurs again and again, and its scope is expanded gradually.PM2.5 is more and more subject to people's attention.
PM2.5 refers to and is suspended in air, the particle of air equivalent Zhi Jing≤2.5um.PM2.5 can directly enter alveolar through human body respiration, and the carrier that can be used as bacterium enters human body, affects respiratory system, cardiovascular even cause cancer, very big to harm.Current screen window on the market mainly preventing dust, anti-mosquito is as main, cannot get buffer action to PM2.5.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of screen window that is suitable for using under haze weather condition composite window screen cloth, and its energy high efficiency filter PM2.5, purifies the air of a room, thereby ensure health.
The technical solution of the utility model is specific as follows.
The one that the utility model provides purifies PM2.5 screen window composite window screen cloth, is five-layer structure, comprises successively from outside to inside outer gauze layer, the first nonwoven layer, PTFE microporous film layers, the second nonwoven layer and interior gauze layer; Wherein: three limit closures between described the first nonwoven layer and the second nonwoven layer, form hatch frame, PTFE microporous film layers is placed in opening; Or PTFE microporous film layers and the first nonwoven layer, the second nonwoven layer all fit tightly.
In the utility model, in the time forming hatch frame between the first nonwoven layer and the second nonwoven layer, be equipped with hair side and hook face at openend.
In the utility model, between described outer gauze layer and interior gauze layer, three limits are connected, and form hatch frame.
In the utility model, described PTFE microporous film layers grammes per square metre 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.
In the utility model, the gauze density of described outer gauze layer is less than the gauze density of interior gauze layer.
Advantage and the good effect that the utlity model has are: the utility model adopts multistage filtering pattern to entering indoor air filtration, and outer gauze layer is a filtration beds; The first nonwoven layer is secondary filter layer, and it can trap fine particle through Electrostatic Treatment, and the electrostatic field of generation and weak current can sterilizations; PTFE microporous barrier is three filtration bedss, its material advantage is that aperture is little, porosity is high, can intercept more fine dusts particle, air through these three times filter after again through the second nonwoven layer, interior gauze layer, finally enter indoor, realize the multistage filtering of air, dustproof, sterilization, anti-mosquito are effective.Under haze weather condition, can enter the PM2.5 in room air by high efficiency filter, to ensureing that indoor human body health has remarkable effect.
Brief description of the drawings
Fig. 1 is a kind of PM2.5 of purification screen window composite window screen cloth overall structure schematic diagram.
The outer gauze layer of number in the figure: 1-; 2-the first nonwoven layer; 3-PTFE microporous film layers; 4-second is without anti-layer of cloth; Gauze layer in 5-.
Detailed description of the invention
For better understanding summary of the invention of the present utility model, enumerate embodiment below, coordinate accompanying drawing to be described in detail as follows.
Embodiment 1
?a kind of PM2.5 of purification screen window composite window screen cloth is provided in the present embodiment, is five-layer structure, comprises successively from outside to inside outer gauze layer 1, the first nonwoven layer 2, PTFE microporous film layers 3, the second nonwoven layer 4 and interior gauze layer 5; Outer gauze layer 1 is common gauze, plays integral support effect, requires good mechanical property, is attached at the first nonwoven layer 2 outsides; The nonwoven of the first nonwoven layer 2 must be through Electrostatic Treatment, in order to trap fine particle, sterilization; It is 1.0 ~ 4.0g/m that PTFE microporous film layers 3 is selected grammes per square metre
2, pore size is 0.1 ~ 1.0 μ m, porosity is 80 ~ 90%, the PTFE microporous barrier that air penetrability is 8 ~ 15cm/s, the special PTFE microporous barrier of for example PM2.5 mouth mask.PTFE microporous film layers 3 adopts hot-press method to be closely overlying in the first nonwoven layer 2 and the second nonwoven layer 4, can intercept more fine dusts particle.Interior gauze layer 5 is attached in the second nonwoven layer 4, and the gauze density of interior gauze layer 5 is greater than the gauze density of outer gauze layer 1; Interior gauze layer 5 adopts import high-quality gauze, and it can be through up to ten thousand push-and-pull frictions and indeformable, and are difficult for expanding with heat and contract with cold, good mechanical property; Above-mentioned nonwoven layer is selected excellent adsorption, easily adsorption electrostatic, good permeability, single-layer nonwoven that light transmission is good, and the attaching of nonwoven layer and gauze adopts the making of some compression technology.
PTFE microporous barrier, as the important component part in the utility model, is 1.0 g/m when selecting grammes per square metre
2, pore size is 0.5 μ m, when PTFE microporous barrier that porosity is 80%, the air penetrability of PTFE microporous barrier is 8cm/s.Now composite window screen cloth air penetrability minimum, filtration PM2.5 effect is best; Be 4.0g/m when selecting grammes per square metre
2, pore size is 1.0 um, when PTFE microporous barrier that porosity is 90%, the air penetrability of PTFE microporous barrier is 14cm/s.Now composite window screen cloth air penetrability maximum, indoor lighting is best.
Composite window screen cloth compact conformation for the purification PM2.5 screen window obtaining in sum, is easy to install, dismantle long service life.Can multistage filtering air, to PM2.5 good purification, to a certain degree sterilization, purifies and enters indoor air, ensures health, can prevent in addition the intrusion of mosquitos and flies, comprises common screen window effect.
Embodiment 2
The one that the present embodiment provides purifies PM2.5 screen window composite window screen cloth, with the same in embodiment 1, be five-layer structure from outside to inside, be but distinguish, between its PTFE microporous film layers 3 and the first nonwoven layer 2, the second nonwoven layer 4, do not fit tightly, its first nonwoven layer 2, the second nonwoven layer 4 three limit closures, another side opens, and forms hatch frame, and openend is equipped with hair side and hook face, PTFE microporous barrier is inserted in opening and sealed, form PTFE microporous film layers 3.
Or adopt sewing tech that outer gauze layer 1 and three limits of interior gauze layer 5 are connected to form to hatch frame; Being combined into that PTFE microporous film layers 3 and the first nonwoven layer 2, the second nonwoven layer 4 form is placed therein.
The advantage of said structure is that this structure facilitates replacing or the cleaning of PTFE microporous film layers 3.It under haze weather condition, can enter the PM2.5 in room air by high efficiency filter equally, to ensureing that indoor human body health has remarkable effect.
