Description
Technical Field
The invention relates to the technical field of textile materials, in particular to a piece of dirt-resistant clothing and a preparation method thereof.
Background
Along with the development of society, the development of technology makes organic polymer materials have various functions, including optical, electrical, magnetic, separation, shape memory, etc. Such materials generally have other functional properties than the usual structural materials, in addition to mechanical properties. The development and application of organic polymer materials with various functions in daily life have been the subject of development by a wide range of organic chemistry researchers.
At present, more and more functional organic polymer materials are widely applied to daily textile clothes, such as fire-fighting clothes with flame-retardant and heat-insulating functions and fire-extinguishing blankets; racing clothes with anti-collision protection function and bulletproof clothes; diving suit with waterproof and compression-resistant functions. Meanwhile, a plurality of newly developed functional organic polymer materials are not widely applied to daily textile clothes, such as shape memory organic materials, organic photoelectric materials, organic magnetic materials and the like. The organic materials have the same performance as inorganic materials, the density is far smaller than that of the inorganic materials, and meanwhile, the organic materials are easy to adjust and modify through chemical reaction, so that the organic materials have good application prospect. The invention prepares the organic photoelectric material and the organic magnetic material through reaction, and combines the organic photoelectric material and the organic magnetic material into the fiber to prepare the clothing, the magnetic field change of the dust and the inherent magnetic field of the organic magnetic material interact through the photo-magnetic effect to generate vibration so as to lead the dust to fall off, and meanwhile, the electron hole generated by the illumination of the organic photoelectric material and the electric field generated by the diversion under the inherent magnetic field of the organic magnetic material achieve the effect of sterilization.
Disclosure of Invention
The invention aims to provide a piece of dirt-resistant clothing and a preparation method thereof, which are used for solving the problems in the prior art.
The dirt-resistant clothing is characterized by mainly comprising the following components in parts by weight: 8-12 parts of ferromagnetic organic metal compound, 10-15 parts of polyacrylic acid and 20-25 parts of modified conjugated macromolecular polymer.
Preferably, the ferromagnetic organic metal compound is prepared by complexation reaction of modified thiophene and ferric chloride.
The modified thiophene is prepared by occupying the beta position of thiophene by one of straight-chain sodium alkoxides with 6-12 carbon atoms.
As optimization, the modified conjugated macromolecular polymer is prepared by adding hexabenzocoronene in the pi-pi stacking polymerization process of conjugated macromolecules and then reacting with hydrogen peroxide.
The conjugated macromolecule is prepared by reacting 1, 2-phthalaldehyde with 1, 4-cyclohexanedione, then reacting with carbon tetrabromide, and finally reacting with p-hydroxyphenylboric acid.
As optimization, the dirt-resistant clothing comprises the following raw material components in parts by mass: 12 parts of ferromagnetic organic metal compound, 15 parts of polyacrylic acid and 25 parts of modified conjugated macromolecular polymer.
As optimization, the preparation method of the dirt-resistant clothing mainly comprises the following preparation steps:
(1) Reacting 4, 4-bis (4-hydroxyphenyl) valeric acid with 1, 4-dichlorobutane to obtain polybutadienediphenyl valeric acid, reacting polybutadienediphenyl valeric acid with epoxycorticosterone acetic anhydride, and placing the reaction product in sulfuric acid solution to obtain modified polybutadienediphenyl valeric acid;
