Summary of the invention

The purpose of the present invention is providing a kind of high dielectric hydrophobic finishing method of textile material for existing problem, Textile material according to this method preparation has excellent high dielectric property and hydrophobic performance.

The present invention is achieved by the following technical solutions:

A kind of high dielectric hydrophobic finishing method of textile material, includes the following steps, following raw materials by weight:

(1) preparation of composite coating slurry:

To 3-4 parts of dispersing agents are added in the nano barium phthalate, 4-5 parts of nano silvers of 35-40 parts of coating modifications, 80-90 parts are added Deionized water after ultrasonic disperse handles 30-40min, 15-25 parts of acrylic ester adhesives is added while stirring, are adjusted with ammonium hydroxide PH is 8-10, and 2-3 parts of thickeners are added dropwise and are uniformly mixed, obtain composite coating slurry；

Holimium oxide, magnesia, manganese oxide are coated on nano barium phthalate surface first with precipitating cladding process, then will by sintering Ho³⁺、Mg²⁺、Mn²⁺It is diffused into nano barium phthalate, adjusts its dielectric properties；Cladding holimium oxide contributes to form " core-shell " structure Crystal grain can significantly improve the dielectric-temperature stability of nano barium phthalate；Using the nano barium phthalate of coating modification, Argent grain as function Body, acrylate are that adhesive is prepared for composite coating slurry；

(2) the coating final finishing of textile material:

The textile material of chemical etching processing is fixed on and is applied in layer frame, by gained composite coating slurry in (1) in textile material Surface is uniformly scratched, then the textile material of coating is placed in 70-80 DEG C of baking oven and is heat-treated 5-10min, then is warming up to 120-130 DEG C of heat treatment 3-6min, obtains high dielectric coat textile material；

The Alkali reduction chemical etching processing of textile material, the weaving handled with chemical etching are realized using the processing method of improvement Material is base fabric, and using the nano barium phthalate of coating modification, Argent grain as functive, acrylate is that adhesive is prepared for compound painting Layer slurry, is handled using the textile material that coating final finishing mode handles chemical etching, preparation high dielectric constant weaving Material；Nano barium phthalate differs larger with surface energy polymer difference, gradually appears particle with the increase of nano barium phthalate packing ratio Reunion, and then generate gap hole, coating textile material dielectric constant increases, and the introducings of nano silver particles is so that coating is weaved Material dielectric constant improves, and since Coulomb blockade effect coating textile material dielectric loss maintains reduced levels；

(3) hydrophobic finishing of textile material:

1-2 parts of tridecafluoro-n-octyltriethoxysilanes, 0.4-0.5 parts of aminopropyl triethoxysilanes are dissolved in 6-7 parts of ethyl alcohol In the mixed liquor of 0.6-0.7 parts of water, vinegar acid for adjusting pH on the rocks is 5, after magnetic agitation 30-50min, is added drop-wise to 12-13 part two In silica hydrogel, after being stirred to react 2-4h, then ultrasonic uniform, adjusting pH is mixed with 16-19 parts of water, 1-2 parts of amido silicon oils For 8-9,0.1-0.2 parts of dopamines are added and stir evenly, 2- is wherein reacted into the high dielectric coat textile material submergence of gained in (2) It after 4h, takes out, rinsed with a large amount of clear water, bake 20-30min through 40-45 DEG C of drying, at 130-140 DEG C, it is hydrophobic to obtain high dielectric The textile material of arrangement；

Due to being connected with each other between nanoparticle, poly-dopamine, silicone elastomer three with covalent bond, the modified of preparation is spun It knits material surface and goes out preferable hydrophobic performance, by constructing for the compound coarse structure of micro-nano, by the weaving material of alkali decrement treatment For material after hydrophobically modified processing, all there is very big promotion in water contact angle and grafting rate；Modified textile material also has There is higher corrosion resistance, when being corroded by 98% concentrated sulfuric acid,

Concentrated sulfuric acid solution cognition tumbles rapidly from surface and does not leave apparent trace；

Further, in step (1) nano barium phthalate coating modification: it is different that 4-9 parts of nano barium phthalate 1:10 are added to solvent Barreling 1-2h obtains suspension in propyl alcohol, and 2-4 parts of holmium nitrates, 3-6 parts of magnesium acetates, 0.5-1 parts of manganese acetates are dissolved in 55-110 parts In ionized water, barreling 1-2h in suspension is added, it is 10 that ammonium hydroxide, which is added dropwise, to pH, and magnetic agitation 1-2h generates precipitating, is aged 1-2h Afterwards, it filters, wash, drying, pre-burning 1-2h obtains the nano barium phthalate of coating modification at 600-610 DEG C.

Further, in step (2) textile material chemical etching processing method: first by textile material ethyl alcohol and water logging Ultrasound 30-40min removal of impurities is steeped, then is soaked in the sodium hydroxide solution of 370-390g/L, is taken out after 5-10min, uses preservative film Package is put into 105-110 DEG C of baking oven after heating 3-5min, is cleaned with a large amount of clear water, is dried at 80-85 DEG C, obtain chemical quarter Lose the textile material of processing.

Further, the control of step (2) coating thickness is in 0.5-1mm.

The present invention has the advantage that compared with prior art

(1) coating modification is carried out to nano barium phthalate: is coated on holimium oxide, magnesia, manganese oxide first with precipitating cladding process Nano barium phthalate surface, then by being sintered Ho³⁺、Mg²⁺、Mn²⁺It is diffused into nano barium phthalate, adjusts its dielectric properties；Cladding Holimium oxide contributes to form " core-shell " structure crystal grain, can significantly improve the dielectric-temperature stability of nano barium phthalate；Changed with cladding Property nano barium phthalate, Argent grain be functive, acrylate be adhesive be prepared for composite coating slurry.

(2) the Alkali reduction chemical etching processing that textile material is realized using the processing method of improvement, at chemical etching The textile material of reason is base fabric, and using the nano barium phthalate of coating modification, Argent grain as functive, acrylate is adhesive preparation Composite coating slurry, is handled using the textile material that coating final finishing mode handles chemical etching, prepares high dielectric Constant textile material；Nano barium phthalate differs larger with surface energy polymer difference, with nano barium phthalate packing ratio increase gradually There is the reunion of particle, and then generate gap hole, coating textile material dielectric constant increases, the introducings of nano silver particles so that Coating textile material dielectric constant improves, and since Coulomb blockade effect coating textile material dielectric loss maintains lower water It is flat.

(3) it due to being connected with each other between nanoparticle, poly-dopamine, silicone elastomer three with covalent bond, prepares Modified textile material surface go out preferable hydrophobic performance, by constructing for the compound coarse structure of micro-nano, by alkali decrement treatment Textile material hydrophobically modified processing after, all there is very big promotion in water contact angle and grafting rate；Modifying textile Material corrosion resistance also with higher, when being corroded by 98% concentrated sulfuric acid,

Concentrated sulfuric acid solution cognition tumbles rapidly from surface and does not leave apparent trace.
