Functional type non-woven fabrics be concentrated mainly on antibacterial field, lack for can releasing negative oxygen ion, purify air
The research and development of functional type non-woven fabrics.
Chinese patent CN105269889A discloses a kind of anionic film, at common non-woven fabric or glass-fiber-fabric table
Topcoating covers Vermiculitum, tourmaline slurry coating obtains anionic film, described Vermiculitum, tourmaline slurry coating by
Expanded vermiculite 0-30wt%, tourmaline 0-10wt% and adhesive 60-90wt% mix.This anion
Film plays in the coating that the effective ingredient of releasing negative oxygen ion effect is common non-woven fabric or glass-fiber-fabric surface
Vermiculitum and tourmaline, owing to effective ingredient is on surface, in conjunction with firm not, and easily abrasion makes effect
Fruit declines, and this coating also makes the breathability on non-woven fabrics or glass-fiber-fabric surface decline simultaneously, limits applicable model
Enclose.
Chinese patent CN102517802A discloses a kind of filter nonwoven fabric capable of releasing negative ions, is to use high-pressure electrostatic
Spin processes is prepared from, and the spinning liquid of employing includes following component and weight percent content: isopropanol
55～70%, deionized water 10～20%, polythene-ethenol 10～15%, carbon fibre 3～10%, nanometer
Zinc oxide 2～10%, nanoscale negative ion powder 3～10%.For preparing the fiber of non-woven fabrics in this patent
In inorganic filler content accounting big, the nano-particle of existing zero dimension, have again one-dimensional carbon fibre, this is all
The seriality that can make fiber is bad, and intensity is low.
Summary of the invention
Defect that the purpose of this utility model is contemplated to overcome above-mentioned prior art to exist and provide a kind of thoroughly
Gas and water repellency are good, and preparation technology is simple, is widely used, releasing negative oxygen ion persistent period length and energy
Enough purify the non-woven fabrics of the releasable negative oxygen ion of air.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of non-woven fabrics of releasable negative oxygen ion, including the non-woven fabrics body layer from inside to outside set gradually,
Water repellent coating and grid protection layer, described non-woven fabrics body layer is made up of polypropylene fibre, polypropylene fibre
In dispersed have tourmaline particle and activated carbon granule.
Described water repellent coating is polytetrafluorethylecoatings coatings, is coated in the surface of non-woven fabrics body layer.
Described grid protection layer is monolayer mesh fabric, covers the surface in water repellent coating.
The particle diameter of described tourmaline particle is 2～5 μm, particle diameter 2～5 μm of activated carbon granule.
Preferably, the particle diameter of described tourmaline particle is 2～3 μm, particle diameter 2～3 μm of activated carbon granule.
Preferably, the mass ratio of described tourmaline particle and the gross mass of activated carbon granule and polypropylene fibre
For (4～8): 100, tourmaline particle is (0.1～10) with the mass ratio of activated carbon granule: 1.
A diameter of 10～20 μm of described polypropylene fibre.
Preferably, a diameter of 15～20 μm of described polypropylene fibre.
The preparation method of the non-woven fabrics of this releasable negative oxygen ion, comprises the following steps:
(1) tourmaline particle, activated carbon granule and polypropylene are prepared compound mother after mixing, extrusion
Grain, wherein, the gross mass of tourmaline particle and activated carbon granule with the mass ratio of polypropylene fibre is
(4～8): 100, tourmaline particle is (0.1～10) with the mass ratio of activated carbon granule: 1；
(2) composite master batch is prepared after high-temperature fusion, spray webbing non-woven fabrics body layer；
(3) coating water repellent coating in non-woven fabrics body layer, then cover grid protection layer, i.e. obtaining can
The non-woven fabrics of releasing negative oxygen ion.
The technique preparing non-woven fabrics body layer uses conventional producing technology of non-woven fabrics.
Tourmaline particle and activated carbon granule can first carry out surface modification, more mixing with polypropylene, make granule
Dispersibility is more preferably, and more preferable with polyacrylic combination.
Non-woven fabrics body layer of the present utility model can releasing negative oxygen ion, realize water repellent merit by water repellent coating
Can, polytetrafluorethylecoatings coatings is high temperature resistant, has anti-flammability, simultaneously works as fire retardation, outermost grid
Protective layer plays and strengthens structural strength and the effect of protection water repellent coating, prevents water repellent coating in use
Come off due to abrasion.
This utility model preferred single layer mesh fabric, little to the weight of non-woven fabrics, and monolayer net
Shape structure is conducive to the permeability of non-woven fabrics.
This utility model is filled with tourmaline and activated carbon granule in the fiber constituting non-woven fabrics, passes through
Tourmaline and activated carbon granule are filled in the fibre, makes non-woven fabrics.The highfield that tourmaline is formed makes
The water being in electric field can be decomposed, and produces negative oxygen ion, utilizes the loose structure of activated carbon granule to catch sky
Hydrone in gas, " draws " in the highfield around tourmaline particle by the hydrone in air, further
Strengthen tourmaline and produce the ability of negative oxygen ion, and on the one hand the loose structure of activated carbon granule is conducive to fall
Low-fiber density.If inorganic material accounting is little, the tourmaline in non-woven fabrics not sufficiently forms electric field net,
The efficiency producing negative oxygen ion being reduced, and inorganic material accounting is big, the intensity of fiber is easily reduced, and combines
Close and consider that selecting inorganic material of the present utility model and polyacrylic mass ratio is (4～8): 100.Inorganic particle
Particle diameter is 2～5 μm, and particle diameter is too small, then prepare difficulty；Particle diameter is excessive, and specific surface area is little, active surface electricity
Lotus amount is few, and the electric field intensity near granule is low, and excessive particle diameter can affect the intensity of fiber.Due to electricity
The sphere of action of the highfield of gas stone is that in the range of tens microns of surface, therefore the diameter of fiber can not mistake
Greatly, diameter is excessive so that water cannot effectively reach in the highfield that tourmaline is formed.The diameter of fiber is also
Can not be too small, diameter is too small, and in spinning process, inorganic filler easily blocks shower nozzle, according to tourmaline and work
The particle diameter of property charcoal granule, a diameter of 10～20 μm of fiber of the present utility model, the diameter range simultaneously selected
Make to be formed between the fiber of non-woven fabrics countless micropore, good air permeability.
Compared with prior art, non-woven fabrics of the present utility model has releasing negative oxygen ion and purification air continues
Time length, the function such as effective and breathability and water repellency are good.
