Description
Technical field
The present invention relates to the technical field of non-woven material, specifically a kind of compound melt-blown nonwoven cloth fabric and its
Preparation method.
Background technology
Nonwoven cloth material made of meltblown is using polypropylene as primary raw material, and die head spinneret orifice is squeezed with high velocity, hot air
The polymer melt stream gone out carries out drawing-off, is consequently formed superfine fibre and condenses upon on solidifying lace curtaining or roller, and relies on itself
Bond and formed.Fibre diameter can reach 1~5 micron, and these have the superfine fibre increase of unique capillary structure single
The quantity and surface area of position area fiber, have stronger suction-operated, therefore occupy very in filtering material to solid particle
Big advantage；And the bonding between polymer fiber relies primarily on the heat bonding of itself and formed, what this mode was formed non-knits
It is fluffy to make material structure, lighter in weight and soft.When surface density is identical, other nonwovens of the thickness ratio of melt-blown nonwoven cloth material
Cloth material is thick, when melt-blown non-woven material is filtered in use, particulate matter is greatly increased by the path length of material, particle
The probability that thing retained by fiber, adsorbs is obviously improved.In addition to acupuncture filter material, its application is most wide, turns into highly effective air
The first choice of filtering material, but the fire resistance currently used for the non-woven fabrics of flue gas filtering is inadequate, and due to melt-blown nonwoven
The filtration resistance increase of the superfine fibre of cloth, can influence the discharge of pernicious gas in flue gas.
The content of the invention
The invention aims to solve the problems of the prior art, there is provided a kind of compound melt-blown nonwoven cloth fabric and
Its preparation method.
To achieve these goals, technical scheme is as follows：A kind of compound melt-blown nonwoven cloth material, the material
Material contains polypropylene fibre, and described material also includes inorganic combustion inhibitor and nanofiber.
Preferably, the particle diameter of described nano-fiber material is 1nm-75nm.
Preferably, in described non-woven fabric material, the weight of polypropylene fibre, nano-fiber material and inorganic combustion inhibitor
Number is respectively polymer fiber 70-75 parts, nano-fiber material 20-25 parts, inorganic combustion inhibitor 0-5 parts.
Preferably, in described non-woven fabric material, the weight of polypropylene fibre, nano-fiber material and inorganic combustion inhibitor
Number is respectively polymer fiber 70-75 parts, nano-fiber material 23-25 parts, inorganic combustion inhibitor 3-5 parts.
Preferably, described inorganic combustion inhibitor includes any one of aluminium hydroxide, magnesium hydroxide.
Above-mentioned compound melt spraying non-woven fabrics material preparation method includes：Described preparation method is included in fusion-jetting polypropylene
Nano-fiber material is arrived into superfine fibre surface with high temperature gas flow injection in the forming process of fiber.
Preferably, described preparation method be included in before compound melt-blown nonwoven cloth material is formed by polypropylene with it is inorganic
Fire retardant powder is sufficiently mixed uniformly, carries out melt-spraying spinning jointly.
The present invention has advantages below compared with prior art：
In summary, compound melt-blown nonwoven cloth material of the present invention, during for filtering flue gas
While filtering noxious gas can be played, nonwoven cloth material will not be destroyed because of the high-temperature gas discharged from flue gas, and
And nano-fiber material is located at the compound melt-blown nonwoven cloth material that polymeric fiber surface is formed and compares meltblown polypropylene fibres
Filtration resistance substantially reduce.
Embodiment
The invention discloses a kind of compound melt-blown nonwoven cloth material, the material contains polypropylene fibre, described material
Material also includes inorganic combustion inhibitor and nano-fiber material.
Having many uses for nanofiber, is such as implanted into fabric face by nanofiber, can form one layer of stable gas membrane,
Double thin property interfaces fabric is made, it is both waterproof, again can be grease proofing, antifouling；The advanced protective garment made of nanofiber, its fabric are more
Hole and there is film, can not only make air permeable, tool can respiratory, moreover it is possible to minuteness particle is kept out the wind and filtered, has block to aerosol,
Can anti-chemical and biological weapons and noxious material.In addition, nanofiber can be additionally used in the purification of the products such as chemical industry, medicine, filtering etc..
And the most important parameter for influenceing air cleaner strainability is：Particle diameter, air velocity, fibre diameter and
Filling rate.Generally speaking fiber is thinner, fills more closely knit, be more uniform, and the filtrable particle of institute is smaller, and filter efficiency is higher,
But corresponding filtration resistance is also bigger.The filter efficiency for being meltblown base fabric is 30%, and layers of nanofibers surface density only reaches in base fabric
0.7g/m2When, filter efficiency can increases to 92%, is 2.4g/m in layers of nanofibers surface density2When, filter efficiency reaches
100%.
Therefore the present invention uses a kind of compound melt-blown nonwoven cloth material not only to increase the filter efficiency to flue gas,
And smoke rate is not interfered with, avoid the formation of blocking.
