Embodiment 1

[0034]Cold-resistant, twist-resistant, flame-retardant foam coating glue, raw material weight ratio:

[0035] Mix soft elastic foam coating glue 80, blocked isocyanate crosslinking agent 2, and high-permeability softener 1, and then add crystalline type II ammonium polyphosphate 20, expanded graphite 10, and polytetrafluoroethylene micropowder 4. The high-speed stirring of the machine makes the material fully mixed into the air to reach the foaming state, and the volume of the mixed material is increased by 1-1.5 times, and the coating glue is obtained.

[0036] Cold-resistant, twist-resistant, flame-retardant foam coating treatment method:

[0037] (1) Fabric pre-calendering treatment, pressure 9 Mpa, temperature 60 ℃, speed 20m / min;

[0038] (2) Use the coating glue prepared by the above method to coat the fabric, and bake at 150°C-155°C-155°C-160°C for 2 minutes.

Embodiment 2

[0040] Cold-resistant, twist-resistant, flame-retardant foam coating glue, raw material weight ratio:

[0041] Mix flexible elastic foam coating glue 88, blocked isocyanate crosslinking agent 2.5, high penetration softener 2, mix and stir evenly, then add crystal type II ammonium polyphosphate 22, expanded graphite 12, polytetrafluoroethylene micropowder 5, use dispersion The high-speed stirring of the machine makes the material fully mixed into the air to reach the foaming state, and the volume of the mixed material is increased by 1.5-2 times to obtain a coating glue.

[0042] Cold-resistant, twist-resistant, flame-retardant foam coating treatment method:

[0043] (1) Fabric pre-calendering treatment, pressure 9 Mpa, temperature 70 ℃, speed 15m / min;

[0044] (2) Use the coating glue prepared by the above method to coat the fabric, and bake at 150°C-155°C-155°C-160°C for 2.5 minutes.

Embodiment 3

[0046] Cold-resistant, twist-resistant, flame-retardant foam coating glue, raw material weight ratio:

[0047] Mix flexible elastic foam coating glue 95, blocked isocyanate crosslinking agent 3, high penetration softener 2.5, mix and stir evenly, then add crystal type II ammonium polyphosphate 24, expanded graphite 13, polytetrafluoroethylene micropowder 5.5, use dispersion The high-speed stirring of the machine makes the material fully mixed into the air to reach the foaming state, and the volume of the mixed material is increased by 2-2.5 times to obtain a coating glue.

[0048] Cold-resistant, twist-resistant, flame-retardant foam coating treatment method:

[0049] (1) Fabric pre-calendering treatment, pressure 10 Mpa, temperature 65 ℃, speed 25m / min;

[0050] (2) Use the coating glue prepared by the above method to coat the fabric, and bake at 150°C-155°C-155°C-160°C for 3 minutes.

Abstract

The invention provides a cold-resistant anti-twisting anti-bending flame-retardant foamed coating adhesive for a textile and a treating method. The cold-resistant anti-twisting anti-bending flame-retardant foamed coating adhesive is prepared by uniformly mixing, by weight, 80 to 100 of a flexible and elastic foamed coating adhesive, 2 to 4 of an enclosed type isocyanate cross-linking agent and 1 to 3 of a high-permeability softening agent under stirring, then adding 20 to 25 of crystal II type ammonium polyphosphate, 10 to 15 of expandable graphite and 4 to 6 of micro polytetrafluoroethylene powder, and adequately introducing air until a foaming state is reached so as to allow the size of the obtained mixture to increase by 1 to 3 times so as to obtain the coating adhesive. A fabric is subjected to calendering pretreatment and then coated with the prepared coating adhesive. The coating adhesive is simple and convenient to produce, effectively overcomes the problem of hygroscopicity of ammonium polyphosphate and the problem of meltability of a flame-retardant textile, and has good flame retardation, cold resistance, twisting resistance, bending resistance and air permeability; and the treated fabric has good elasticity and is comfortable to wear.

Description

technical field [0001] The invention relates to textile post-finishing technology, in particular to a cold-resistant, twist-resistant, flame-retardant foaming coating glue applied to chemical fiber, pure cotton and chemical fiber and cotton blended fabrics and a treatment method. technical background [0002] Flame-retardant coating technology is a common textile functional finishing technology. Currently, traditional halogen flame retardants are better and cheaper, but they will produce a lot of toxic and harmful fumes during their use. [0003] At present, environmentally friendly phosphorus-nitrogen flame retardants are widely used. Among them, ammonium polyphosphate is a non-halogen flame retardant with non-toxicity, good stability and good flame retardancy, and its flame retardancy mainly comes from the synergistic effect of phosphorus and nitrogen; but as a powder filler used in textiles, its Its own strong moisture absorption will lead to a decrease in the flame reta...
