Description
Technical field
The present invention relates to high-molecular compound preparing technical fields, being suitable for opposed polarity model in particular to one kind
Enclose the aromatic polymer fiber of high composite performance and preparation method thereof of matrix resin.
Background technology
Aromatic polymer fiber is a kind of heat safe high-performance fiber of high-strength and high-modulus, and mostly important application is exactly
High-Performance Composite Materials Based on Resin as Matrix is prepared as reinforcement, suffers from and is widely applied in multiple military civil fields, including
With rubber is compound prepares tire and sebific duct, and epoxy resin, bimaleimide resin is compound prepares aircraft structure composite wood
Material, high-end sports equipment is prepared with polypropylene composite materials.But aromatic polymer fiber does not have also as composite material reinforcement body
Have and play its excellent performance completely, this is because the overall performance of composite material depends not only on resin matrix and fiber
Performance, also and the interfacial adhesion of composite material is closely bound up.Aromatic polymer fiber possesses higher crystallinity and surface
Smooth, inertia is presented in surface, so it is poor with the adhesive property of various resins, so that the composite material prepared by it
It can be far below expection.
Generally, the adhesive property at fiber/polymer object interface is determined by three kinds of interactions.They are (1) machines
Tool lock knot；(2) polarities match；(3) it is chemically bonded.These interactions can be accordingly by increased fiber surface area, introducing
Van der Waals force/chemical bond etc. between electrostatic interaction and fiber and resin is introduced.Have largely about fibre at present
Dimension table face, which is modified, to be reported to introduce these interactions, including soda acid processing, chemical oxidation, plasma and γ radiate and
Directly fluorination etc..However, most methods may be only available for a kind of resin matrix.This is because being glued with different resins matrix
It is different to tie the interaction needed, especially polarities match interacts.Different resin system polarity is different, they are needed
The fiber of opposed polarity carries out polarities match.For example, in order to improve the adhesive property of fiber/epoxy resin, phosphoric acid processing is commonly used
Fiber introduces polar carboxyl and hydroxyl on surface, is matched with improving the higher epoxy resin of fiber surface polarity and polarity
(Zhao J.Effect of surface treatment on the structure and properties of para-
aramid fibers by phosphoric acid[J].Fibers and Polymers,2013,14(1):59-64.).And
When carrying out compound tense with natural rubber, the above method is clearly inappropriate, this is because the polarity of rubber matrix itself is relatively low,
This requires the surfaces of aromatic polymer fiber should also have lower polarity, introduces carboxyl and hydroxyl further destroys instead
Polarities match in interface.Therefore, it is necessary to obtain it is a kind of can with the matrix resin of opposed polarity range have good interface
Aromatic polymer fiber of compatibility and preparation method thereof.
In view of this, special propose the present invention.
Invention content

Enough active groups being chemically bonded with the base resin.
According to an aspect of the present invention, the invention further relates to the aromatic polymer fibres that method as described above is prepared
Dimension.
Since the benzimidazole group on aromatic polymer fiber is utilized as reaction site in the method for the present invention, carry out
Silica coarse structure is introduced into fiber surface by grafting, greatly improves the tree of fiber surface and various opposed polarity ranges
Mechanical lock knot interaction between fat, is then re-introduced into amino, epoxy group, vinyl using the Si-OH structures of silica
Deng, and these groups can be formed at interface with the resin of opposed polarity range and are chemically bonded, it will by strong chemical bond
Fiber is connected with resin, therefore significantly improves the caking property of polymer fiber and the various resins of opposed polarity range
Can, obtain a kind of aromatic polymer fiber of the high composite performance suitable for opposed polarity range matrix resin.
Since the method for the present invention is in the group (such as benzimidazole group) of aromatic polymer fiber surface chemical constitution
Macromolecular side group reaction is carried out, macromolecular main chain is completely retained, and chemical oxidation treatment, plasma irradiation etc. are relied on other
It is compared by the method for breaking to form active site of macromolecular main chain, does not destroy fiber bodies structure, can effectively solve to be modified
In journey the problem of fiber bodies mechanical properties decrease, the excellent results of the high composite performance of not damaged modification are realized.
Method and process provided by the invention is easy, and cost is relatively low, and modified effect is good, has stronger application prospect.
