Technical field

The present invention relates to non-woven fabrics waste material resource utilization field, more particularly to prepares magnetic carbon cloth using non-woven fabrics waste material Method and its magnetic carbon cloth and application.

Background technique

Non-woven fabrics industry has the characteristics that with short production cycle, high degree of automation, product audient are wide.Nonwoven production process In can generate a large amount of leftover bits and other wastes.It is not still formed at present for these waste materials, in industry efficient and rational Technology it is disposed.Other than small part waste material can be melted down and be re-melted, most waste material is at present mainly with landfill It is disposed with two ways is burned, waste material is low using added value.During landfill, the coloring agent in non-woven fabrics easily leads to soil and ground It is lauched and pollutes.And using incineration technology disposition non-woven fabrics waste material, then energy consumption is excessively high.Zero emission and waste recovery are to nothing Woven fabric industry is of great significance, and can not only further decrease nonwoven production cost, and it is attached can also effectively to promote waste material It is value added.Carbon cloth, which is prepared, as predecessor using non-woven fabrics waste material agrees with non-woven fabrics industry Green Development direction.

However dispose non-woven fabrics waste material using the mode that traditional atmosphere increases temperature, prepared char-forming material not only ash compared with High and electric conductivity and magnetic property are poor.It can even if loading some metal oxides on the fabric char-forming material surface of nonwoven by the later period To reduce the resistivity of fired carbon cloth to a certain extent, however not only process is complicated and to utilize waste non-woven fabric for later period load Cost has risen considerably for material production carbon cloth.

Microwave can be directed through material and enter inside it, balancedly be heated to material, and hydrone Blang is utilized to transport Mechanism significantly shortens the heating temperature raising time, and material may make to be carbonized rapidly under anaerobic.It is forerunner with non-woven fabrics waste material Object, the carbon cloth using microwave technology production high-performance, high added value is the key that solve the above problems.

Summary of the invention

Goal of the invention: magnetic carbon is prepared using non-woven fabrics waste material technical problem to be solved by the invention is to provide a kind of The method of cloth

Second technical problem to be solved by this invention prepares magnetic carbon cloth using non-woven fabrics waste material there is provided a kind of And its application.

Technical solution: in order to solve the above-mentioned technical problem, this invention takes the following technical solutions: a kind of to utilize nonwoven The method that cloth waste material prepares magnetic carbon cloth, the preparation method comprises the following steps:

2) non-woven fabrics is immersed in the sulphur ferrous solution that step 1) obtains, under air-proof condition, immersion 30~60 minutes, then Taking out non-woven fabrics and drying to its moisture content is 20%~40%；

3) non-woven fabrics for obtaining step 3) carries out microwave activation in MICROWAVE PROTECTION gas；

4) after reaching default microwave Deal with Time, terminate microwave activation, taken out after being cooled to room temperature and obtain magnetic carbon cloth.

Wherein, the iron ion in the step 1) iron chloride and sodium persulfate and peroxydisulfate molar ratio 2~5: 1.

Wherein, peroxydisulfate concentration is 0.01~0.05M in step 1) the sulphur ferrous solution.

Wherein, non-woven fabrics of the invention includes singly being not limited only to polypropylene fibre, terylene, polyamide fibre, viscose rayon, acrylic fibers, polyethylene, chlorine One of synthetic fibre non-woven fabrics etc..

Wherein, the step 2) non-woven fabrics and sulphur ferrous solution solid-to-liquid ratio are 1: 1~2mg/mL.

Wherein, the MICROWAVE PROTECTION atmosphere in the step 3) is nitrogen or argon gas.

Wherein, the microwave power in the step 3) is 600~900W, and microwave Deal with Time is 30~120 minutes.

The content of present invention further includes the magnetic carbon cloth that the preparation method prepares.

Wherein, the magnetic carbon cloth resistivity is 1.37~1.94 Ω m, 0.03~0.12mT of magnetic induction intensity.

The content of present invention further includes application of the magnetic carbon cloth in processing industrial wastewater.

The content of present invention further includes application of the magnetic carbon cloth in terms of preparing permeable membrane, electrode material, adsorbent material.

The working principle of the invention: under microwave action, the hydrone aggravation movement being trapped in non-woven fabrics gap is generated A large amount of heat, temperature rapid increase for entire non-woven fabrics.At high temperature, peroxydisulfate decomposes first generates potentiometric titrations. Potentiometric titrations can effectively decompose the pigment in oxidation non-woven fabrics, generate carbon dioxide free radical.Carbon dioxide free radical Part iron ion is restored, ferrous ion is generated.With the lasting raising of temperature, thermal cracking takes place in part non-woven fabrics, real Now gradually deoxidation is carbonized.In non-woven fabrics carbonisation, nonwoven surface generates the volatilization that erosional surface can promote cracking to generate The diffusion of property organic matter and iron ion.At the same time, heavy metal element micro in iron ion, ferrous ion and non-woven fabrics passes through It captures volatile organic matter gas molecule and absorbs the oxygen atom of non-woven fabrics cracking desorption, generate magnetic ferrites particle.Volatilization Property organic gas molecule timely capture and the fast transfer of oxygen atom further improve non-woven fabrics carbonation rate.

The utility model has the advantages that preparation manipulation process of the present invention is simple, agents useful for same is from a wealth of sources, can directly be commercialized popularization.This It invents and non-woven fabrics waste material carbonisation is strengthened simultaneously by iron ion and peroxydisulfate and generates in carbon cloth surfaces and effectively adds Carry magnetic ferrites.Resistivity minimum 1.37 Ω m of the present invention using the magnetic carbon cloth of non-woven fabrics waste material preparation, magnetic induction Intensity 0.12mT.The present invention not only effectively realizes the effective use of non-woven fabrics waste material, and also the production for magnetic carbon cloth has supplied one Kind new approaches.
