[0025] An aspect of the embodiments of the present invention provides a method for preparing a multifunctional superhydrophobic textile finishing agent, which includes:
[0026] (1) Disperse the precursor of the oxide sol and the graphite oxide aqueous dispersion in deionized water, add an anionic surfactant, and stir at room temperature for 20 to 30 minutes. After uniform dispersion, add a catalyst for hydrolysis and condensation reactions to form a mixed reaction system;
[0027] (2) Heating the mixed reaction system obtained in step (1) to 30-50° C., stirring and reacting at a speed of 200-1000 rpm for 3-12 hours, and then ultrasonically treating for 10-20 minutes to form a hydrosol;
[0028] (3) Add a functional agent to the hydrosol obtained in step (2), and perform ultrasonic treatment for 10-100 min to obtain the multifunctional superhydrophobic textile finishing agent.
[0029] In some embodiments, the precursor includes any one or a combination of two or more of tetr...
Embodiment 1
[0052] (1) Disperse 10 mL of tetrabutyl titanate and 4 mL of graphite oxide aqueous dispersion (concentration: 10 mg / mL) in 200 mL of deionized water, add 0.1 g of sodium dodecylbenzenesulfonate, and stir vigorously at room temperature for 20 min, After uniform dispersion, 5 mL of hydrochloric acid with a concentration of 0.1 mol / L was added dropwise to carry out hydrolysis and condensation reactions.
[0053] (2) The temperature of the mixed reaction system obtained in step (1) was raised to 30° C., and the magnetic stirring reaction was continued at a speed of 300 rpm for 3 h, followed by ultrasonic treatment for 10 min to obtain a clear and transparent hydrosol.
[0054] (3) Add 5mL of octyltriethoxysilane, 1gTiO 2 and carbon black, 0.2g polyphosphoric acid, 0.2g nano-silver and 0.4g silk protein, and then ultrasonically treated for 50 minutes to obtain a uniform and stable dispersion, which is the multifunctional superhydrophobic textile finishing agent.
