Description
Technical field
The present invention relates to technical field of fiber preparation, and in particular to a kind of permanent anti-static acrylonitrile copolymer and its fibre
Tie up preparation method.
Background technique
The electrical property of high molecular material depends primarily on two physical quantitys, i.e. resistivity and dielectric constant, the resistance of material
Rate is lower, and the ability of dissipation electrostatic is stronger, and dielectric constant is lower, is often more easy to produce electrostatic.However, most of macromolecule materials
Expect surface resistivity (> 10 all with higher12Ω) with lower dielectric constant, therefore, this kind of material does not have antistatic property
Can, cause it to cause various problems and difficulty because of accumulation of static electricity in practical applications, for example, communication apparatus computer room can be because of electrostatic
There is random fault, malfunction or run-time error when computer being caused to run in accumulation, it is also possible to lead to certain components (MOS electricity
Road, bipolar circuit etc.) breakdown and breaking-up;Coal production and petrochemical industry production inventory transportational process can be led because of accumulation of static electricity
Cause fire explosion;Electrostatic caused by clothes friction can be such that the blood alkalinity of people increases, and cause pruitus, pigment heavy
, interfere the mood etc. of people.Make high molecular material that there is antistatic effect, most efficient method is exactly into high molecular material
Antistatic agent is added, to reduce its resistivity, improves conductive capability.
Currently, the antistatic agent of commercialization is many kinds of, wherein there is ionic liquid hardly possible to volatilize, steam forces down, ion-conductance
Conductance height, electrochemical window mouth width, the advantages that optical clarity is high are a kind of antistatic agents haveing excellent performance, therefore by people
Extensive concern.Application No. is a kind of polyacrylonitrile/ionic liquid is disclosed in 201510146416.9 Chinese invention patent
Body/polyaniline composite material preparation method, should be the preparation method comprises the following steps: right after first mixing aniline monomer with ionic liquid
Polyacrylonitrile plasticising and machine-shaping;Then shaped article is post-processed, i.e., under the acid condition containing oxidant, made
The aniline of interiors of products after molding occurs polymerization reaction and generates polyaniline, finally obtains polyacrylonitrile/ionic liquid/polyaniline
Conducing composite material.Application No. is disclosed in 201110237446.2 Chinese invention patent a kind of High-elasticity conductive fiber and
Preparation method, this method are to be uniformly mixed carbon nanotube with ionic liquid, are then blended again with strong flexible polymer, finally
Spinning is carried out, High-elasticity conductive fiber is obtained.But above-mentioned patent is all made of the mode system that ionic liquid is blended with macromolecule matrix
Standby conductive fiber, can not fundamentally solve the problems, such as ionic liquid precipitation easy to migrate, so can not achieve the permanent anti-of fiber
Electrostatic.In addition, polyaniline and carbon nanotube color are deeper, influence fiber can dyeability.
Application No. is disclosing in 201510449504.6 Chinese invention patent, a kind of permanent anti-static ionic liquid is high
Ionic liquid is grafted in a manner of being graft-polymerized and is total to by the block of monomer and acid anhydrides preparation by the preparation method of polymers masterbatch
On polymers, ionic liquid migration precipitation is solved the problems, such as with this, the high polymer masterbatch obtained using this method can effectively be dropped
The surface resistivity of low high molecular material makes material reach antistatic ability, in addition, high polymer masterbatch and a variety of high polymers are all
With good compatibility.Although the electric conductivity of ionic liquid is excellent, used using ionic liquid as single antistatic agent
In producing and exploitation antistatic products are primarily present two problems: on the one hand, ionic liquid as a kind of ionic anti-static agent,
It is influenced by ambient temperature and humidity than more serious;On the other hand, the ionic liquid largely haveing excellent performance is expensive, and adding proportion is big
Cause production cost excessively high.Application No. is disclosing in 02111399.8 Chinese invention patent, a kind of anti-static polyacrylonitrile is fine
The preparation method of dimension, has used that cost is lower, the stronger polyethylene glycol of wettability power is as antistatic agent.But the patent is only
It is that polyethylene glycol and polyacrylonitrile blended, the problem of equally existing antistatic agent migration precipitation be cannot achieve into permanent anti-static
Performance.Use polyethylene glycol to be primarily present following problems as antistatic agent: when additive amount is lower, antistatic property is poor;Addition
When measuring too high, water sorption is strong, causes material surface viscosity too high, influences following process and use.
