Abstract
The invention discloses a kind of preparation method of aromatic polyamide staple fiber that metallizes and stand-by provisions processed, the device is equipped with Porous Base in the plating cylinder of plating cylinder group and porous pressing plate constrains the fiber of tiling, fibre metal is carried out in conjunction with the mode that liquid circulation in storage tank acts on fiber in plating cylinder, it specifically includes tiling fiber, decontamination, pretreatment, reduction, the step of chemical plating and dehydration and drying, using device and method of the present invention by the way of the fixed liquid circulation of fiber, it is possible to prevente effectively from being intertwine with each other between aramid fiber short fibre, and different types of metallization aramid fiber short fibre can be prepared in batches.
Description
Technical field
The present invention relates to a kind of preparation method of staple fiber and stand-by provision processed more particularly to a kind of fragrant adoptions of metallization
The preparation method of amide staple fiber and stand-by provision processed belong to organic fiber metal lining technical field.
Background technique
Aromatic polyamide fibre abbreviation aramid fiber, English are Aramid fiber, are developed earliest by DuPont Corporation, are
A kind of typical and most widely used high performance fibre material, has high-strength, Gao Mo, high temperature resistant, ingrain fireproofing and acid-fast alkali-proof
Equal excellent properties, are widely used in the high science and technology field such as aerospace.Aramid fiber mainly has p-aramid fiber (poly- paraphenylene terephthalamide
P-phenylenediamine, PPTA, Fanglun l414) and meta-aramid (poly, PMIA, aramid fiber 1313) two types
Type, wherein PPTA have superelevation it is strong and modulus, be mainly used in Lightweight high-strength composite material reinforcing material and it is shellproof,
The protective materials such as explosion-proof, anti-cutting；PMIA takes adaptive with good, is mainly used for high-performance individual protection field.Two class aramid fibers
Molecular structure it is as follows:
Aramid fiber surface is metallized, so that obtaining one kind has both aramid fiber lightweight, high-strength, flexible and metal material
Excellent electricity, magnetic property are always a hot research problem in the novel conductive fibrous material of one.Aramid fiber surface gold
Categoryization, commonly used chemical plating process realize that comprehensive existing disclosed patented technology is also primarily present following ask at present
Topic: (1) using the strong corrosives reagent such as the concentrated sulfuric acid and metalating reagent (NaH-DMSO), although can effectively realize to aramid fiber fibre
The surface etch of dimension, but it is easy to cause the excessive loss of fibrous mechanical property；(2) complex technical process, some are also continuing to use chlorine
Change the traditional handicraft of stannous and palladium chloride activation sensitization；(3) fiber is easy to intertwine with each other during plating, it is difficult to realize that batch is made
It is standby.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of preparation methods of aromatic polyamide staple fiber that metallizes
And stand-by provision processed, in conjunction with herein described device and using herein described simple process and to the small no palladium of fibre damage
Depositing process is learned, can effectively avoid the entanglement between fiber, and is able to achieve efficient, batch the production preparation metallization short fibre of aramid fiber
Dimension.
The technical scheme is that
The invention discloses a kind of metallization aromatic polyamide staple fiber stand-by provision, which includes passing through pipeline
The plating cylinder group and liquid storage groove group of tandem connection circulation, and plate the pipeline between cylinder group and liquid storage groove group and be equipped at least one
A circulating pump, wherein
Plating cylinder group includes the plating cylinder of several tandems connection, and the bottom of each plating cylinder is positioned puts equipped with a tiling
The Porous Base set, and the movable positioning in top for plating cylinder is equipped with the porous pressing plate that a tiling is placed, and plates Porous Base in cylinder
The accommodating area for the fiber that tiles is formed between porous pressing plate；
Liquid storage groove group includes that several of parallel connection independently pass in and out the storage tank of liquid, which includes extremely
A few decontamination liquid storage tank, at least one cleaning solution storage tank, at least one pretreatment fluid storage tank, at least one reducing solution storage tank and
At least one metal plating liquid storage tank, wherein decontamination liquid storage tank is provided with decontamination liquid, and cleaning solution storage tank is provided with cleaning solution, pretreatment
