Embodiment 1

[0025] Embodiment 1: (1) Cotton fabric is cut into the piece of fixed size, removes the grease and the wax on fabric surface with ether. Using citric acid as a modifying reagent and sodium hypophosphite as a catalyst, a modified solution was prepared, wherein the content of citric acid in the modified solution was 9wt% (citric acid: sodium hypophosphite = 3:2), and the cotton fabric Carboxyl modification is carried out by dipping in the modifying solution twice and rolling, and the modified fabric must be placed for more than 12 h to achieve equilibrium.

[0026] (2) Under the condition of 35±0.5 ℃, add 0.1 mol / L dilute NH 3 · h 2 O solution was added dropwise to 200 mL polyvinylpyrrolidone solution (10 g / L) to adjust the pH of the system to 10.0±0.2, and then 0.05 mol / L MgCl was added at a rate of 10 mL / hr 2 The solution was added dropwise to dilute NH 3 · h 2 In the mixed liquid of O solution and polyvinylpyrrolidone, the liquid addition time lasts for 2 h, during whi...

Embodiment 2

[0034] (1) Cut the sulfonamide fabric into blocks of a fixed size, remove the oil agent on the surface of the fabric with ether, and use 7.5g / l sodium hydroxide as a modifying agent to immerse the sulfone fiber fabric in the modifying solution for two Carboxyl modification is carried out by dipping and padding, and the modified fabric must be placed for more than 12 hours to achieve equilibrium.

[0035] (2) Under the condition of 35±0.5 ℃, add 0.1 mol / L dilute NH 3 · h 2 O solution was added dropwise to 200 mL polyvinylpyrrolidone solution (10 g / L) to adjust the pH of the system to 10.0±0.2, and then 0.05 mol / L MgCl was added at a rate of 10 mL / hr 2 The solution was added dropwise to dilute NH 3 · h 2 In the mixed liquid of O solution and polyvinylpyrrolidone, the liquid addition time lasts for 2 h, during which, 0.1mol / L NH 3 · h 2 The pH value of the O solution control system is in the range of 10.0-10.5. After the liquid addition is completed, the reaction solutio...

Abstract

The invention discloses a preparation method of an open-fire resistance thermal insulation textile. The preparation method comprises the steps of: firstly modifying fiber surfaces, so that the fiber surfaces generate a plurality of-COOH groups so as to adsorb Mg(OH)2 seed crystals, then adopting a secondary growth method to enable the Mg(OH)2 seed crystals to grow for the second time on the fiber surfaces, preparing Mg(OH)2 crystal films which are completely coated on the fiber surfaces, then mixing a high-temperature resistance polymer solution and different dosages of organic pillar vermiculites by taking a high-temperature-resistant polymer phenolphthalein-based polyether sulphone as a continuous phase, so as to realize the uniform mixing of high-temperature-resistant polymers with different proportions and the organic pillar vermiculites by a physical means of supersonic wave cell smashing, coating fiber fabrics by the prepared high-temperature-resistant polymers and a vermiculite mixed liquid, wherein magnesium hydrate crystal films grow on the surfaces of the fiber fabrics, and forming vermiculite film protective layers with different thicknesses on the fiber surfaces through appropriate thermal treatment, so as to obtain the textile with strong open-fire resistance and thermal insulation property. The open-fire resistance thermal insulation textile prepared by using the preparation method has the advantages of improving the open-fire resistance and the thermal insulation property.

Description

technical field [0001] The present invention relates to the use of flaky Mg(OH) on fibers 2 The combined effect of crystal film and polyarylethersulfone / vermiculite composite film protective layer is used as the outer layer material of special protective clothing such as fire fighting uniforms, which improves the fireproof and heat insulation ability of the outer layer material, and has a long-term open flame resistance for development. A method for preparing a fire-resistant and heat-insulating textile that plays a decisive role in a fire-fighting combat uniform with high heat insulation, comfort and flexibility. Background technique [0002] With the acceleration of China's urbanization process, high-rise and super high-rise buildings are gradually increasing, and more and more people work and live in them, and the accompanying fire problems in high-rise buildings are also attracting more and more attention from the world. According to fire data statistics, it is known th...
