Technical field
The present invention relates to aramid fiber field of material technology, specifically a kind of modification of aramid fiber and its processing technology.
Background technique
Aramid fiber is the general designation of aromatic polyamide fibre, and according to the difference of chemical structure, aramid fiber can be divided into together
Position aramid fiber (MPIA) and para-aramid fiber (PPTA), amido bond and phenyl ring on p-aramid fiber molecular structure form π and are total to
Yoke effect has very high inward turning position energy, and strand stretches shape in rigidity, and there are very strong intermolecular hydrogen bonding, these structures
Characteristic imparts aramid-fiber super-high intensity, high-modulus, excellent heat resistance and dielectric properties, in aerospace material, body
It educates the fields such as articles, rubber product to have a wide range of applications, aramid fiber is ideal rubber framework material, and aramid fiber is not only
The performances such as high temperature resistant, fire-retardant, shock resistance, pressure resistance can be injected for traditional rubber product, while lightweight and section can also be reached
Can effect, although aramid fiber has excellent comprehensive performance, there is also interfacial adhesion performance is poor, compression modulus is small, resists
The disadvantages such as Compressive Strength is low, this is because active force is smaller between aramid fiber rigidity straight chain molecule, crystallinity is high, lacks chemical activity
Functional group.Therefore, processing is modified to the surface of aramid fiber, improves aramid fiber and rubber interface binding performance is very
It is necessary.
Traditional fiber surface modification means are divided into chemically and physically method, and chemical modification is by Strong oxdiative, chlorination, table
The chemical reactions such as face grafting carry out surface to fiber and are modified, i.e., introduce active group in fiber surface, pass through chemical bonding or pole
Property effect improve the interface binding power between fiber and matrix, chemic modified method has at high cost, severe reaction conditions, equipment requirement
The defects of high grade I toxicities are big.The processing such as plasma, electron beam, ultrasonic wave, radiation are common physical modified methods, pass through object
Reason modification can perform etching fiber surface, and introduce hydroxyl, carboxyl isoreactivity group or activated centre in fiber surface, with into
The reaction of one step initiation grafting, improves the physics and chemical state of fiber surface, improves the interface binding power between fiber and matrix, object
The modified active force for easily forming non-covalent bond on the surface of the material of reason, this active force have certain unstability and timeliness,
It easily causes the loss of material property therefore to find a kind of method for being effectively improved aramid fiber surface simultaneously, is that aramid fiber is multiple
Condensation material field urgent problem to be solved.

It is dry, obtain modification of aramid fiber.
As optimization, a kind of processing technology of modification of aramid fiber, the processing technology of the modification of aramid fiber includes following
Step:
(1) cleaning of aramid fiber: weighing aramid fiber, be placed in dehydrated alcohol, be cleaned by ultrasonic 1-3h, be then placed in again from
It is cleaned by ultrasonic 1-2h in sub- water, is placed in 60-100 DEG C of vacuum oven dry 3-5h；Aramid fiber is used to anhydrous second respectively
Pure and mild deionized water ultrasonic cleaning, is the grease stain and impurity in order to remove aramid fiber surface；
(2) pretreatment of aramid fiber: being immersed in 1-12h in sulfuric acid solution for step (1) resulting aramid fiber, stands after taking-up
10-30min is rinsed with deionized water, is then placed in sodium bicarbonate solution and impregnates 3-8min, use deionized water after taking-up again
10-20min is rinsed, dry 3-5h is placed in 60-80 DEG C of vacuum oven；Sulfuric acid is small molecule inorganic acid, low concentration
The corrosivity of sulfuric acid solution is milder, even if handling aramid fiber under heating conditions, to the strength loss of aramid fiber
Also smaller, using sulfuric acid treatment aramid fiber, aramid fiber occurs hydrolysis, makes the amido bond in aramid fiber macromolecular
Fracture, aramid fiber surface generate carboxyl；By aramid fiber sulfuric acid solution 1-12h, is considering energy-saving and saving
While time, is conducive to acid ion and hydrogen ion in sulfuric acid solution to spreading inside aramid fiber, keeps aramid fiber molten
Swollen and hydrolysis is more abundant；

In amido bond fracture, aramid fiber surface generates a certain number of carboxyls, and when sulfuric acid concentration is too low, aramid fiber surface is raw
At carboxyl negligible amounts；When acid concentration is too high, the hydrolysis strength of aramid fiber has been more than equalization point, and the hydrolysis of aramid fiber is strong
Power reduces instead, and it is 20-80% that the optimum concentration of concentrated acid solution, which is mass fraction,；It is fine in 30-80 DEG C of at a temperature of processing aramid fiber
Dimension, can promote the warm-up movement of hydrogen ion, be conducive to it to the absorption of aramid fiber surface and to inside aramid fiber
Diffusion, enhances the swelling and hydrolysis of aramid fiber, swelling action reduces the interaction between aramid fiber macromolecular
Power enters aramid fiber ontology for hydrogen ion and provides access, and heating accelerates amido bond fracture, so that aramid fiber
Carboxyl is more easily generated on macromolecular chain；Sodium bicarbonate solution is used for neutralisation of sulphuric acid solution.
As optimization, MgCl in step (4)2The mass fraction of ethanol solution is 3-8%.
As optimization, the mass concentration of aqueous dopamine solution is 1-5g/L in step (5).
As optimization, the pH value of buffer solution is 8-9 in step (5).
Compared with prior art, the beneficial effects of the present invention are:
A kind of modification of aramid fiber of the present invention and its processing technology, the present invention first using sulfuric acid solution to aramid fiber at
Reason, aramid fiber hydrolyze, Surface Creation carboxyl；Secondly the aramid fiber of Surface Creation carboxyl is taken with thionyl chloride
Generation reaction carries out chloride to aramid fiber；The aramid fiber of chloride is passed through into MgCl again2Ethanol solution processing, MgCl2
Complex reaction occurs with the carbonyl in aramid fiber molecule, aramid fiber surface etches groove, and surface becomes coarse；Finally again
Aramid fiber is handled by aqueous dopamine solution, self-polymeric reaction occurs for dopamine, and it is more to deposit a strata in aramid fiber surface
Bar amine coating, since aramid fiber passes through MgCl2Ethanol solution processing, the groove that aramid fiber surface etches can promote to gather
Dopamine coating is deposited on aramid fiber surface, so poly-dopamine coating coats more uniform in aramid fiber, more causes
It is close, so that aramid fiber is kept original form, improves the interface performance of aramid fiber, interface binding power is mentioned
It is high；In the preparation process of entire modification of aramid fiber, green, environmental protection, simple process have been operated, and are suitable for industrialized production.
