Special flame retardant for nylon fabrics and preparation method of special flame retardant

Abstract

The invention relates to the field of C09K21 / 04, in particular to a special flame retardant for nylon fabrics and a preparation method of the special flame retardant. The special flame retardant is prepared from the following raw materials: a polyhalogenated aromatic compound, a nitrogen oxide, a protein refined derivative and an auxiliary agent, and the relative molecular mass of the protein refined derivative is 220-400. The flame retardant is good in flame retardant effect, can realize non-combustibility of nylon 66, and is suitable for various application scenes; after being coated with the flame retardant, the flame retardant has no influence on the mechanical property of the nylon 66; and the flame retardant in the prior art can reduce the oxidation resistance and wear resistance of nylon 66, and the flame retardant specifically solves the problems.

Description

technical field [0001] The invention relates to the field of C09K21 / 04, in particular to a special flame retardant for nylon fabric and a preparation method thereof. Background technique [0002] Nylon 66 is a thermoplastic resin composed of polyhexamethylene adipamide with high mechanical strength and mechanical strength. It is widely used in engineering plastics, mechanical accessories and synthetic fibers, but its flammability limits its use in many other fields. Therefore, the design concept of flame retardant nylon 66 has a very broad application prospect. [0003] CN109836817A discloses a halogen flame retardant and its application, using materials such as decabromodiphenylethane, aluminum fluoride, zinc borate, antimony trioxide, etc., the prepared flame retardant can be used for fire extinguishing, and reduces the flame retardant It is difficult to produce, but its compatibility with fabrics is poor, and it is not washable, so it cannot be applied to fabrics.

[0002] Nylon 66 is a thermoplastic resin composed of polyhexamethylene adipamide with high mechanical strength and mechanical strength. It is widely used in engineering plastics, mechanical accessories and synthetic fibers, but its flammability limits its use in many other fields. Therefore, the design concept of flame retardant nylon 66 has a very broad application prospect

[0003] CN109836817A discloses a halogen flame retardant and its application, using materials such as decabromodiphenylethane, aluminum fluoride, zinc borate, antimony trioxide, etc., the prepared flame retardant can be used for fire extinguishing, and reduces the flame retardant It is difficult to produce, but it has poor compatibility with fabrics and is not washable, so it cannot be applied to fabrics

[0004] CN102876030A discloses a composite environmentally-friendly flame retardant for nylon 66 and nylon 66 flame-retardant plastics, and uses materials such as antimony trioxide and melamine cyanurate to prepare a special flame retardant for nylon 66. However, when it is applied to clothing, it is easy to cause clothing to change. hard, less skin-friendly
