In order to solve the above problems, a non-woven fabric with good mechanical properties, antistatic properties and abrasion resistance and a preparation method thereof are needed.
Disclosure of Invention
The invention aims to provide an anti-static wear-resistant non-woven fabric and a preparation method thereof, so as to solve the problems in the background technology.
In order to solve the technical problems, the invention provides the following technical scheme:
the anti-static wear-resistant non-woven fabric comprises the following raw material components: 30-40 parts of filler, 80-100 parts of polyethylene terephthalate, 80-100 parts of polytrimethylene terephthalate, 50-60 parts of coating liquid and 50-60 parts of polypropylene resin dispersion liquid.
Further, the filling material comprises the following raw material components: 50-60 parts of zirconium tetrachloride, 20-25 parts of 2-amino terephthalic acid, 30-35 parts of silver nitrate, 15-18 parts of polyvinylpyrrolidone and 21-24 parts of ferric trichloride.
The filler uses a metal organic framework taking high-valence metal zirconium as a center and takes the metal organic framework as a carrier to load the silver nanowires, and compared with the conventional metal organic framework, the metal organic framework taking zirconium as the center has higher crosslinking strength with the silver nanowires; the property in the reaction system is more stable; the metal organic framework with abundant redox active sites is also beneficial to the later growth of polyaniline and polypyrrole on the surface.
Further, the coating liquid comprises the following raw material components: 30-60 parts of repair master batch, 20-25 parts of aniline, 40-50 parts of pyrrole and 30-40 parts of butyl titanate.

After the prepared fiber filaments are made into non-woven fabrics, a layer of coating liquid is coated on the surfaces of the non-woven fabrics; the coating liquid is specially added with a repair master batch containing polyrotaxane; the polyrotaxane is mainly prepared by modifying hydroxyl-terminated polyethylene glycol into p-benzenesulfonyl-terminated polyethylene glycol and then carrying out self-assembly on the modified polyethylene glycol and cyclodextrin; the polyrotaxane is a supermolecular compound, has a unique topological structure, can form a mechanical interlocking structure with other macromolecules in the non-woven fabric, is mixed with polydimethylsiloxane, isophorone diisocyanate and dibutyltin dilaurate to prepare a repair master batch, and is coated on the non-woven fabric, so that the non-woven fabric has certain self-repair capability; when the surface coating of the non-woven fabric is scratched due to aging or external force factors, polyrotaxane molecular chains in the surface coating of the non-woven fabric can move, hydrogen bonds among the molecular chains are exchanged, new entanglement is generated among the molecular chains, and the healing of the scratch of the surface coating of the non-woven fabric is promoted; the polyrotaxane contains a large amount of hydrophilic hydroxyl groups, so that the prepared non-woven fabric has good moisture absorption and air permeability and is not easy to generate static electricity. Aniline and pyrrole in the coating liquid are subjected to in-situ oxidative polymerization on the non-woven fabric under the action of an initiator ammonium persulfate to generate polyaniline and polypyrrole; polyaniline and polypyrrole are mutually connected through electrostatic interaction, and meanwhile, the polyaniline and the polypyrrole are connected with polyrotaxane and a metal organic framework through coordination bonds and hydrogen bonds to generate a continuous and ordered hydrogel structure on the surface of the non-woven fabric, wherein the mechanical strength of the non-woven fabric can be remarkably enhanced through the synergistic effect of the hydrogen bonds and the coordination bonds; polypyrrole and polyaniline have stronger conductivity, and particle transmission ties can be formed on the surface of the non-woven fabric by the growth of the polypyrrole and polyaniline on the surface of the metal organic framework, so that the electron transfer rate is increased, and the problem of low conductivity of the metal organic framework is further solved; meanwhile, polyaniline and polypyrrole have certain tensile and bending properties, and when the polyaniline and the polypyrrole grow on the non-woven fabric, on one hand, the stability of the metal organic framework can be improved, so that the polyaniline and the polypyrrole are not prone to swelling and collapsing in the long-term use process, and on the other hand, the polyaniline and the polypyrrole can cooperate with the bending properties of the non-woven fabric and are not prone to falling off. A layer of polypropylene resin dispersion liquid is attached to the outer layer of the non-woven fabric to protect the non-woven fabric, and the prepared non-woven fabric has better wear resistance, antistatic property and mechanical property.

And (3) testing antibacterial performance: according to GB/20944.3-2008, evaluation of antibacterial performance of textiles part 3: testing by an oscillation method; the test results are shown in Table 2:
table 2.
As is clear from the data in the table, the surface resistances of the nonwoven fabric samples obtained in examples 1 to 3 were all 1.0X 108-1.3×108The friction voltage is less than 20V, and the antistatic performance is better; the wear-resisting strength is more than 25000 times, the wear resistance is high, the antibacterial effect is more than 99%, the antibacterial effect is good, the performances are excellent, and the non-woven fabric sample prepared in the embodiment 3 has the best effect.
Example 4: the difference from the embodiment 3 is that no filler is added, the filler is used as a winding site when polyethylene terephthalate and polytrimethylene terephthalate are mixed, so that the compatibility of two polyester materials is insufficient, the mechanical strength of the prepared non-woven fabric is deficient, meanwhile, the growth of polyaniline and polypyrrole on the surface of the non-woven fabric is influenced due to the lack of a metal organic framework as a carrier, the antistatic property and the wear resistance of the prepared non-woven fabric are insufficient, and meanwhile, due to the lack of silver nanowires, the antibacterial property of the non-woven fabric prepared in the embodiment is not ideal.
Example 5: the difference from the embodiment 3 is that the repair master batch is not added into the coating liquid, and the prepared non-woven fabric has reduced friction resistance and poor self-repair capability due to the lack of the repair master batch containing the polyrotaxane.
Example 6: the difference from example 3 is that the surface of the fiber filament is not roughened, the contact area between the fiber filament and the coating solution is reduced, physical lock catches are difficult to form between the fiber surface and the coating solution and the polypropylene resin dispersion solution, the adhesion of the coating solution and the polypropylene resin dispersion solution on the surface of the non-woven fabric is reduced, and the abrasion resistance of the non-woven fabric sample prepared in the embodiment is reduced.
Example 7: the difference from the embodiment 3 is that no coating solution is added, a stable three-dimensional network structure is not formed on the surface of the prepared non-woven fabric due to the lack of the coating solution, the bonding force among non-woven fabric fibers is insufficient, the non-woven fabric is easy to scatter and break under the action of external force, the mechanical strength is insufficient, and the prepared non-woven fabric is also deficient in antistatic capability and insufficient in self-repairing capability due to the lack of polyaniline and polypyridine.
Example 8: the difference from the embodiment 3 lies in that a common metal organic framework is used in the filler, the crosslinking strength of the common metal organic framework and the silver nanowires is reduced, the bacteriostasis rate of the non-woven fabric is reduced, meanwhile, the growth of polyaniline and polypyrrole on the metal organic framework is influenced, and the antistatic performance of the prepared non-woven fabric is slightly reduced.
From the above data and experiments, we can conclude that: the filler in the invention improves the problem of insufficient conductivity of a single metal organic framework, and optimizes the antistatic property of the non-woven fabric; the silver nanowires on the non-woven fabric have a strong antibacterial effect. The metal organic framework with the zirconium as the center and rich oxidation-reduction active sites is also beneficial to the growth of polyaniline and polypyrrole on the surface in the later period; the coating solution of the invention generates polyaniline and polypyrrole on the non-woven fabric in situ; polypyrrole and polyaniline have stronger conductivity, and particle transmission bands can be formed on the surface of the non-woven fabric, so that the electron transfer rate is increased, and the antistatic capability of the non-woven fabric is further enhanced; the repair master batch specially added into the coating liquid can enable the prepared non-woven fabric to have self-repair capacity, and the defect that when the repair agent is wrapped in a carrier by a traditional self-repair material, the same part of the fabric is damaged again and can not be repaired for multiple times is avoided; through each component synergism, the elasticity of the prepared non-woven fabric is better, when scratches appear on the surface of the non-woven fabric, the non-woven fabric can be self-repaired by the movement of the subchain in the non-woven fabric coating, and the non-woven fabric is good in antistatic performance, strong in friction resistance, difficult to pilling, firm and durable and has great practical value.
