Abstract

The invention discloses a multifunctional fabric fire retardant as well as a preparation method and application of the fabric fire retardant. The structural formula of the fire retardant is as shown in the specification, wherein in the structural formula, the n is great than or equal to 2 and less than or equal to 10; R<1> is one of H, C(1-6) saturated aliphatic hydrocarbon, C(2-6) unsaturated alkyl and a compound with the structural formula shown in the specification; in the compound, the m is great than or equal to 1 and less than or equal to 10; the R<2> is one of H and C(1-6) saturated aliphatic hydrocarbon; the R<3> is one of H and C(1-6) saturated aliphatic hydrocarbon; R<4> is one of H and C(1-6) saturated aliphatic hydrocarbon. The fire retardant disclosed by the invention belongs to an intumescent fire retardant containing two fire-retardant elements, namely nitrogen and phosphorus and is excellent in fire-retardant effect; N-O bonds and quaternary ammonium ions are contained in molecules and the fire retardant has the functions of low yellowing and sterilization, so that multistep finishing can be realized in one time, the finishing cost of fabrics is greatly reduced and the pollutant discharge amount of printing and dyeing industry can be greatly reduced.

Description

【Technical field】 [0001] The invention relates to a multifunctional fabric flame retardant and its preparation method and application, belonging to the technical field of textile chemical industry. 【Background technique】 [0002] Polymer materials have many superior properties and are widely used in textiles, electronics, machinery, chemicals, aerospace and other fields. With the improvement of people's awareness of fire prevention and the enhancement of the concept of disaster reduction and disaster prevention, people's requirements for flame retardant materials are getting higher and higher, which makes the development, production, promotion and application of flame retardants develop rapidly. Increasingly, the output has risen sharply. [0003] There are usually two ways to prepare flame-retardant textiles. One is the additive type, that is, the flame retardant is mixed with the spinning dope, so that the spun fabric has flame-retardant properties. The other is the post...
