Embodiment 1

[0037] Add 35 parts of FEVE resin with a fluorine content of 25%, a hydroxyl value of 45 mgKOH / g, and an acid value of 5 mgKOH / g, 6 parts of ammonium polyphosphate, 10 parts of titanium dioxide, and 4 parts of nano-silica by adding 20 parts of 150# solvent Oil and 30 parts of methyl isobutyl ketone and mixed solvent, and add an appropriate amount of dispersant, defoamer and leveling agent and other additives, disperse and grind to form a uniform dispersion; then add 15 parts of curing agent Add VP LS2253 into the dispersion liquid and stir evenly to make a coating liquid. Apply the coating liquid on the front and back sides of the polyester fiber cloth by roller coating, and the coating amount is 3.7g / 100cm 2 . Then put the coated fiber cloth into an oven at 110-200° C. to dry for 10 minutes, and then the coated fiber fireproof cloth of the present invention is produced.

Embodiment 2

[0039] Add 42 parts of FEVE resin with a fluorine content of 18%, a hydroxyl value of 65 mgKOH / g, and an acid value of 13 mgKOH / g, 9 parts of ammonium polyphosphate, 13 parts of titanium dioxide, and 2 parts of nano-silica by adding 20 parts of 150# solvent oil and 40 parts of methyl isobutyl ketone, and add an appropriate amount of dispersant, defoamer, leveling agent and other additives, disperse and grind to form a uniform dispersion; then add 23 parts of curing agent Add VP LS2253 into the dispersion liquid and stir evenly to make a coating liquid. Apply the coating liquid on the front and back sides of the polyester fiber cloth by roller coating, and the coating amount is 2g / 100cm 2 . Then put the coated fiber cloth into an oven at 110-200° C. to dry for 15 minutes, and then the coated fiber fireproof cloth of the present invention is produced.

Embodiment 3

[0041] Add 30 parts of FEVE resin with a fluorine content of 26%, a hydroxyl value of 30 mgKOH / g, and an acid value of 2 mgKOH / g, 2 parts of ammonium polyphosphate, 15 parts of titanium dioxide, and 3 parts of nano-silica into 20 parts of 150# solvent Oil and 30 parts of methyl isobutyl ketone and mixed solvent, and add an appropriate amount of dispersant, defoamer and leveling agent and other additives, disperse and grind to form a uniform dispersion; then add 5 parts of curing agent Add VP LS2253 into the dispersion liquid and stir evenly to make a coating liquid. Apply the coating liquid on the front and back sides of the polyester fiber cloth by roller coating, and the coating amount is 3.7g / 100cm 2 . Then put the coated fiber cloth into an oven at 110-200° C. to dry for 3 minutes, and then the coated fiber fireproof cloth of the present invention is produced.

Abstract

The invention discloses a coated fiber fireproof fabric and a preparation method of the coated fiber fireproof fabric. The coated fiber fireproof fabric comprises a fiber base fabric and fluorine coatings formed on both sides of the fiber base fabric. The fluorine coatings are cross-linked solidified layers formed by use of a fluorine-containing resin, a fire retardant, titanium dioxide, nanosilicon dioxide and a hardener. The preparation method of the coated fiber fireproof fabric comprises the following steps: adding the fluorine-containing resin, the fire retardant, the titanium dioxide and the nanosilicon dioxide to a mixed solvent and carrying out dispersing milling to a certain fineness, and filtering to obtain an even dispersion liquid; next, adding the hardener and stirring evenly to obtain a coating liquid; applying the coating liquid to both sides of the fiber fabric in a roller painting method and controlling the coating amount in the range of 2-7g / 100cm<2>; drying the coated fiber fabric in a drying oven at 110-200 DEG C for 3-30 minutes, thereby obtaining the coated fiber fireproof fabric. The coated fiber fireproof fabric is good in flame retardant efficiency and excellent in weather fastness, and meanwhile, has certain antifouling effect and also meets the requirement on the flexing resistance of the fabrics.

Description

technical field [0001] The invention relates to a coated fiber fireproof cloth and a preparation method thereof, in particular to a coated fiber fireproof cloth based on a fluorine-containing coating and a preparation method thereof, belonging to the field of processing and manufacturing fireproof cloth products. Background technique [0002] Fire is one of the major disasters faced by human beings, and fire often causes heavy casualties and property losses. At present, fiber cloth materials are widely used, but their flammability is an important reason for fires. In order to prevent the occurrence of fire or in order to ensure the safety of the public and reduce property losses when a fire occurs, people have tried various methods to protect the fiber cloth from fire and make it into a fireproof fiber cloth. [0003] The treatment method of coating the surface of the fiber cloth material for fire protection can not only maintain the excellent performance of the original fi...
