Description
Technical field
The present invention relates to a kind of preparation method of Nonwoven Filter Material, in particular to a kind of viscose for filtering is living
Property charcoal non-woven cloth and preparation method thereof, belongs to textile material technical field.
Background technique
With the rapid development of social economy and the enhancing of people's environmental consciousness, active carbon is as a kind of low-carbon energy-saving
Product increasingly approves that China also takes a large amount of scientific research energy to the preparation of active carbon by masses.Especially in recent years,
Haze seriously affects people's health, and people need new material reply air pollution, to reduce the shadow to human airway
It rings, and expends a tremendous amount of effort to communicate on research and development new product, such as: active carbon mask.
Traditional activated carbon felt is generally referred to as active carbon nonwoven fabric, has the disadvantage in that 1, by by auxiliary agent and bonding
Agent dissolves and prepares the mode of non-woven cloth dipping in the solution, and adhesive can be by the micropore of activated carbon surface in the method
Blocking, largely effects on absorption property；2, the ratio of auxiliary agent and active carbon is indefinite can make it thicken in improvement process aspect；
3, the adhesive that traditional handicraft uses can be dissolved in water, will receive influence in terms of water filtering；4, traditional to impregnate non-woven cloth
It is directly dried in mixed liquor, its surface can be made full of active carbon powder, cause carbon granule de- in terms of test fabric performance test
The influence fallen makes load charcoal amount lose.
The viscose active carbon non-woven cloth and preparation method thereof that the invention proposes a kind of for filtering.Preparation method is easy
It is easy, the problem of not only solving above-mentioned active carbon nonwoven fabric, and the viscose active carbon that can be used for filtering that is prepared is non-knits
It makes cloth and shows good effect with metal ion, dye filtering field in water filtering, to the sustainable of environmental protection and resource
Development has great progradation.
In textile material technical field, Chinese patent (CN200510049884.0) " active carbon nonwoven fabric and its manufacture work
Skill " is imposed with selectivity to be unreeled step, preceding mixing networking step, sheds active powdered carbon step, selectively impose glue spraying step, add
Heat setting step, product crimping procedure merge active powdered carbon uniform adsorption within non-woven fabrics matrix, then heated sizing system
At product.Chinese patent (CN201120539045.8) " a kind of non-woven fabrics containing active carbon " includes upper layer non-woven fabrics and lower layer
It is equipped with activated carbon non-woven layer of cloth between non-woven fabrics, is equipped with arlt's strata between upper layer, surface is coated with sterilizing layer, has played
Antibacterial is imitated, and can large area absorption peculiar smell and pernicious gas effect." one kind is equipped with lives Chinese patent (CN201410229428.3)
The sanitary napkin of property charcoal nonwoven layer " provides a kind of spunlace non-woven cloth surface layer, non-woven wraps water-absorption fiber sandwich layer and waterproof bottom
Activated carbon non-woven layer of cloth is added between film respectively, with stronger adsorption capacity, and there is antibacterial ability.Chinese patent
(CN201510002711.7) " a kind of active carbon multiple emulsion cladding non-woven sound-absorbing material of polypropylene-base for automobile interiors " will
Multiple emulsion is coated on modified polypropylene matrix and is meltblown manufactured filametntary surface, and the material being prepared not only adheres to
The advantages of conventional polypropylene non-woven material is a kind of automobile-used sound-absorbing material of novel practical.So far, it yet there are no with poly-
Vinyl alcohol, lauryl sodium sulfate and active carbon mixed liquor immersion coating non-woven cloth, reusable heat melten gel two sides heat pressure adhesive obtain
To the appearance of the related process of viscose active carbon Nonwoven Filter Material.
Summary of the invention
There is high absorption, the high viscose active carbon non-woven cloth for carrying charcoal amount in order to obtain, the present invention is by viscose non-woven cloth
It is non-woven to obtain viscose active carbon for immersion coating, reusable heat melten gel two sides heat pressure adhesive by a certain percentage with active carbon and auxiliary agent
Cloth filtering material, for water filtering and metal ion, dye filtering field.The object of the present invention is to provide a kind of for filtering
Viscose active carbon non-woven cloth and preparation method thereof.
To achieve the above object, the technical scheme is that using following steps:
1) active carbon powder for weighing 1.5~6g dry 1~2h in 60~80 DEG C of drying box is added 15~35ml and goes
Ionized water, stirring is uniformly distributed in it in solution, then weighs 0.5~2g lauryl sodium sulfate and the poly- second of 0.5~2g respectively
Enol is separately added into 15~35ml deionized water in beaker, with 5~15min of magnetic stirrer heating stirring until being completely dissolved,
After cooling, first poly-vinyl alcohol solution is added in Actidose, stirring is uniformly mixed to solution, then by lauryl sodium sulfate
Solution is added in mixed liquor, and 5~15min of stirring obtains mixed impregnant liquor to being uniformly mixed；
2) mixed impregnant liquor for obtaining step 1) is coated uniformly on viscose non-woven cloth, is flattened with pressure roller, and temperature is put into
Degree cools down at room temperature to take out to place after 1~3h dry in 60~80 DEG C of drying boxes, obtains active carbon non-woven cloth；
3) the active carbon non-woven cloth melt viscosity for obtaining step 2) serves as a contrast two-sided fixation to get non-to viscose active carbon
Nonwoven filter cloth.
The medium particle diameter of the active carbon is 150~200 mesh.
The polyvinyl alcohol is 1788 type polyvinyl alcohol.
The viscose non-woven cloth is the viscose non-woven cloth that the area cut is 15cm × 20cm.
The material quality ratio of the mixed impregnant liquor is polyvinyl alcohol: lauryl sodium sulfate: active carbon=1:1:3.
The pressure of the pressure roller is 20N ± 2N.
Compared with the background art, the invention has the advantages that:
The present invention carries out immersion coating using viscose non-woven cloth and active carbon, then carries out hot melt adhesive bonding, makes after drying
Sample is obtained, has the characteristics that low-carbon environment-friendly.Viscose active carbon Nonwoven Filter Material be water filtration art have value and
Meaning works well especially in terms of the filtering of metal ion and dyestuff.Present invention improves over adhesives in bonding active carbon
Application method between non-woven cloth, at the same improve traditional dispersing agent and surfactant with when traditional dipping
Mode is prepared using the mode that the coating of maceration extract surface and pressure roller uniformly flatten, and working well for application is practical,
It is not only all of great significance to activated carbon technology processing industrial wastewater, sewage, dyestuff, while improving China's activity
The technology content of charcoal nonwoven product plays good impetus to enterprise development and technical progress of industry.
