The invention also provides a preparation method and use of the gel. In order to conveniently and effectively block PM2.5 particulate matters and other nasal allergens in air from entering the human respiratory system, a gel product prepared from cationic substances, namely, polyquaternary salt and guar gum serving main raw materials is firstly provided and is applied at the periphery of user nose, an air filtration screen-like electrostatic field is produced at the periphery of a nasal passage by virtue of various cations, particulate matter (especially PM2.5) in air can be effectively prevented from entering respiratory systems such as the nasal passages and lungs, PM2.5 is blocked and meanwhile, other nasal allergens in air such as turfgrass clippings, pollen, dust mites, animal and plant dander can also be blocked from entering the human respiratory system, the nasal allergy is avoided and the physical health of respiratory system, heart and lung functions and the like are protected.
Description
Technical field
The present invention relates to and a kind ofly intercept PM2.5 in air or the former gel of other nasal allergies.
Background technology
China in Recent Years major part urban air pollution is serious, haze takes place frequently, in air, macrobead thing is easily by nasal cavity, throat, tracheae is tackled, or got rid of external by the motion of fine hair, and PM2.5 is fine particle thing, once be sucked from respiratory tract by people, the alveolar of people will be deposited on, then dissolve blood of entering, cause septicemia, be easy to reach deep lung, the injury of respiratory system and cardiovascular systems can be caused, there is respiratory tract, cough, expiratory dyspnea, exacerbate asthma shows effect, there is arrhythmia induction heart trouble etc., therefore PM2.5 index has become the index of an important observing and controlling air pollution degree.
The current most domestic common people are the pollution of reply PM2.5, mouth mask is generally used to deal with, but general mouth mask cannot stop pellet, medical mask is mainly for the pellet of more than PM3, and the effect for the pellet of below PM2.5 is less; PM2.5 mouth mask effect is best, filter PM2.5 fine particle efficiency and be greater than 95%, but it has shortcoming also obvious especially: respiratory impedance is higher, is not suitable for child, pregnant woman, heart or the respiratory system person of having any problem and skin sensitivity person use; Do not advise at atmosphere draught-free place or indoor using; Can not wear masks for a long time, otherwise nasal mucosa can be made to become fragile, lose original physiological function of nasal cavity; Mouth mask skin is easily infected with dirt and bacterium, the easy endophytic bacteria of internal layer, and need clean every day, disposablely need change every day, cost is higher.
Summary of the invention
The object of the present invention is to provide and a kind ofly conveniently, effectively intercept PM2.5 in air or the former gel of other nasal allergies.Another object of the present invention is to preparation method and purposes that this gel is provided.
The invention provides and a kind ofly intercept PM2.5 in air or the former gel of other nasal allergies, except purified water, it comprises the component of following weight proportion:
Polyquaternium 0.2% ~ 20%, cation guar gum: 0.1% ~ 10%.
The present invention conveniently effectively intercepts the PM2.5 particulate matter in air and other nasal allergies are former enters human respiratory, a kind of gel product configured for main raw material with cationic substance polyquaternium and cation guar gum is provided first, spread upon user's nose, around nasal meatus, electrostatic field like an air filter screen is produced by various positively charged ion, the particulate matter (particularly PM2.5) that can effectively block in air enters nasal meatus, the respiratory systems such as lung, while obstruct PM2.5, also other nasal allergy sources in air can be intercepted: grass bits, pollen, dirt mite, animals and plants scurf etc. enters respiratory system, avoid causing nose irritated, protection respiratory system, cardio-pulmonary functions etc. are healthy.
The present invention studies discovery, can make the adding of cation guar gum that the proterties of gel is more fine and smooth not to be sticked, gel uniform application can be made at nose, increase barriering effect and the comfortableness of product, use polyquaternary amine salt if simple, then sticking property of product can be made strong, wire drawing phenomenon is serious, not easy to clean, use inconvenience, barriering effect can decline to some extent.Therefore, cation guar gum and polyquaternary amine salt are all critical materialses indispensable in inventive gel product.
Further, described polyquaternium is selected from polyquaternium-6, polyquaternium-7, Polyquaternium-10, Merquat 280, polyquaternium-39, polyquaternium-47, one or more the composition in polyquaternium-76.

Beneficial effect of the present invention is illustrated below by way of test example.
Test example 1 inventive gel is to the iris action of particulate in air
1, object
Observe inventive gel (also can be described as in the present invention " it is quick that PM2.5 hinders the nose ") barriering effect to air pollutant (airborne fine particulate matter PM10, superfine particulate matter).
2, sample
Instrument: YT-HPC3000A (electronics is risen forever in Chengdu) establishes 4 sampling points in same place, accurately 25mg is taken respectively with analytical balance, 50mg, the PM2.5 resistance nose of 75mg is quick as basic, normal, high dosage group (in this experiment, embodiment 2 taken from by gel used), uniform application to 3 is equipped with the surface of the sampling head of PM2.5, PM10 impact head, guarantee is smeared evenly without bubbling, the situation such as do not leak air, separately get an instrument, detecting head surface is kept to clean, do not smear PM2.5 resistance nose quick, as a control group; 4 testers are placed on the height on distance 1.5 meters, ground, keep probe of tester to be in same position.
Sampling time: 60s.
Sampled result is in table 1.
Table 1
According to table 1 data, gel prepared by the present invention effectively can intercept the particulate matter in air, and all has iris action to the particulate matter of different-grain diameter.
The iris action to particulate in air of test example 2 different auxiliary material gel
When with test example 1 polyquaternium and guar gum isoreactivity raw material constant, change other auxiliary materials, by test example 1 experiment operate, the results are shown in Table 2 ~ 5:
Table 2 is adding preservative agent gel not
Table 3 does not add sequestrant gel
Table 4 is not with fungistat gel
Table 5 does not add wetting Agent for Printing Inks gel
Conclusion:
From table 1-table 4 result, when polyquaternium is identical with guar gum ratio, not adding preservative agent, sequestrant, fungistat or wetting Agent for Printing Inks, the barriering effect of product to air pollutant (airborne fine particulate matter PM10, superfine particulate matter) remains unchanged substantially, illustrates that polyquaternium of the present invention and guar gum are the key ingredients intercepting air particle.
Test example 3 cation guar gum is on the impact of gel
When with test example 1 polyquaternium and other auxiliary materials constant, do not add cation guar gum, by test example 1 experiment operate, proterties and test result are in table 6 and table 7:
Table 6 does not add the change of cation guar gum gel character
Table 7 does not add cation guar gum gel
Conclusion:
From table 6 and table 7 result, when polyquaternium is identical with other auxiliary material proportion, do not add cation guar gum, the proterties of product is poor, have to the barriering effect of air pollutant (airborne fine particulate matter PM10, superfine particulate matter) trend obviously diminished, illustrate that guar gum of the present invention is the key ingredient intercepting air particle.
