Problems solved by technology

[0004] In the prior art, the types of flame retardants commonly used for flame retardant treatment of polyester fabrics are conventional additives such as aluminum diethylphosphinate, melamine cyanurate, and ammonium polyphosphate, but these additives themselves have general flame retardant effects. The stability and compatibility are also poor, which limits the further application of polyester fabric itself

Embodiment 1

[0037] Put 5g of TAIC-DOPO, 50g of polyurethane resin, and 10g of toluene into a stirring pot, mix and stir evenly at 25°C to form a uniform coating glue, coat the coating glue on the fiber, and dry it at 150°C for 3 minutes. The LOI of the obtained flame-retardant fiber was 23.3%, and the tensile strength was 51.7 MPa.

Embodiment 2

[0039] Put 30g of TGIC-DOPO, 80g of polyurethane resin, and 15g of xylene into a stirring pot, mix and stir at 20°C for 0.1h to form a uniform coating glue, coat the coating glue on the fiber, and dry at 170°C After 2 minutes, the LOI of the obtained flame-retardant fiber was 23.9%, and the tensile strength was 52.7 MPa.

Embodiment 3

[0041] Put 8g of TAIC-DOPO, 70g of polyurethane resin, 12g of aluminum diethylphosphinate, and 12g of xylene into a stirring pot, mix and stir at 50°C for 0.3h to form a uniform coating glue, and coat the coating glue On the polyester fabric, drying at 180°C for 10 minutes, the LOI of the obtained flame-retardant polyester fabric is 26.7%, and the tensile strength is 54.2MPa.

Abstract

The invention provides phosphaphenanthrene triazine double-radical compound attached fire-retardant fibers. The phosphaphenanthrene triazine double-radical compound attached fire-retardant fibers are mainly prepared from the following raw materials attached on surfaces of fibers in parts by mass: 5-30 parts of a phosphaphenanthrene triazine double-radical compound, 10-15 parts of an organic solvent, 50-80 parts of polyurethane resin and 0-30 parts of other fire-retardant compounds. A preparation method comprises the following steps of: mixing all the raw materials and uniformly stirring; controlling a stirring temeprature at 20-70 DEG C; coating a substance obtained by the step above on the surfaces of the fibers; and drying to obtain a product. The fire-retardant fibers of the phosphaphenanthrene triazine double-radical compound, provided by the embodiment of the invention, take the phosphaphenanthrene triazine double-radical compound as the main raw material; all the raw materials have good compatibility and the prepared fire-retardant fibers have high fire-retardant efficiency; a formed carbon layer is dense and has low poison in a combustion process.

Description

technical field [0001] The invention relates to the field of flame retardant product processing, in particular to a flame retardant fiber attached with a phosphaphenanthrenetriazine double base compound and a preparation method. Background technique [0002] Synthetic fiber is a material with a wide range of uses, and polyester is an important variety in synthetic fiber, and it is the trade name of polyester fiber in my country. It is a fiber-forming high polymer prepared from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or transesterification and polycondensation reactions- - Polyethylene terephthalate (PET), fibers produced by spinning and post-processing. [0003] Polyester fabric is the synthetic fiber with the largest production volume and widest application. It has excellent properties such as high strength, chemical resistance, wrinkle resistance and low price, so it is widely used in clothing fabric...
