Abstract
A kind of Fypro fire retardant, fire-retardant polyamide fibre fiber and preparation method thereof, shown in the chemical structural formula such as formula (I) of the Fypro fire retardant；
Description
Technical field
The present invention relates to field of textile industry, more particularly to a kind of Fypro fire retardant, fire-retardant polyamide fibre fiber and its
Preparation method.
Background technology
Fypro is commonly called as nylon, polyamide fibre, be on molecular backbone containing recurring amide radical group-[NHCO]-thermoplastic
Property fiber general name.Nylon fiber has the characteristics that good wearability, high resilience, dyeability be good, good mechanical performance, can apply with
The fields such as clothes, building, chemical industry.But the hot property of currently used polyamide fibre 6 and polyamide fibre 66 is bad, easy firing, polyamide fibre 6 melts
225 DEG C of point, 264 DEG C of 66 fusing point of polyamide fibre, and its heat decomposition temperature and ignition temperature be at 400 DEG C or more, thus in burning easily
The melting dropping of generation causes fire spreading, so as to limit the application range of nylon fibre.
In recent years, the application field of high molecular material is constantly widened, but thing followed fire also comes clearly into view, largely
Casualties and property loss so that people for high molecular material flame retardant property require be continuously improved.Polymer it is fire-retardant
It is fire-retardant fire-retardant with condensed phase that process according to preventing to burn can be divided into gas phase.Gas phase is fire-retardant mainly largely to be captured in flame zone
Lightweight free radical and hydroperoxyl radical reduce number of free radical, so as to inhibit or interrupt the chain reaction of burning, play and hinder in gas phase
Combustion acts on.Fire-retardant condensed phase is the heat scission reaction course for changing in condensed phase reaction zone fiber macromolecular chain, promotes to occur de-
The reactions such as water, condensation, cyclisation, crosslinking, until charing, to increase carbonization residue, reduces the generation of imflammable gas and into carbon
Protective effect afterwards.
Halogen flame once captured industrial fire retardant half of the country for a long time, but since toxic gas can be generated after its burning,
Its use is limited, and fire retardant focuses primarily upon halogen-free flameproof at present, mainly there is copolymerization method, blending method, finishing method.Copolymerization
Method is to add in the fire retardant with reactivity in the course of the polymerization process to participate in polymerisation, molecular weight and its distribution to polymer
Large effect is generated, is affected to polymer spinning properties, it is also difficult to achieve industrialized production so far；Blending method is to spin
Fire retardant is added to direct fabrics in spinning melt before silk, and finishing method is then to carry out the techniques such as tie dyeing, spraying to fabric.
Being blended and be copolymerized flame-retardant modified effect usually has durability, and the method durability of flame-retardant after-finishing is slightly worse.
The research of polyamide fibre fire retardant is concentrated mainly in polyamide fibre plastics at present, this kind of flame-proof PA 6 often flame retardant agent content
Higher, processing or shaping are affected, suitable for plastics-production, it is difficult to be spun into fiber, such as：CN 104177824B mention one kind
Novel phosphor nitrogen system halogen-free flame-retardant nylon 6 and preparation method thereof；CN 103160949B mention a kind of nano flame retardant nylon 66 fiber and
Its preparation method, using a variety of flame retardant combinations such as organo montmorillonite, ammonium polyphosphate, there are dosage is big, the phase with nylon fibre
Capacitive problem causes the physical mechanical property of nylon fibre to decline.
Graphene (Graphene) be one kind by carbon atom with sp2The cellular flat film that hybrid form is formed, graphite
Alkene has higher specific surface area, lamella iris action, can provide charing point, but cannot independently be used as fire retardant, needs
Cooperative flame retardant effect is played with other fire retardants, it is also poor with the compatibility of high molecular material.CN 103910907A mention one kind
The method of graphene oxide graft modification melamine pyrophosphate fire retardant, stone is grafted to using by melamine pyrophosphate
Black alkene gets on, but melamine pyrophosphate decomposition temperature is relatively low, poor with the compatibility of polyamide fibre, in nylon polymerization object easily
It is precipitated, influences spinning properties, apply in general to, the engineering plastics such as polyamide, polyester.A kind of rich phosphatization stones of CN 106883450A
Black alkene fire retardant and preparation method thereof, there is also with nylon fibre consistency problem.CN 106835333A mention with fire-retardant and
Graphene/the nylon 6 fiber and preparation method of uvioresistant performance, fire-retardant using copolymerization method, the compatibility with nylon 6 fiber is than altogether
It is mixed, but graphene is used alone, and flame retardant effect is bad, and there are problems that industrialized production.
Melamine cyanurate (MCA), containing substantial amounts of amide group (- [NHCO] -), with polyamide fibre compatibility most
Good, heat decomposition temperature height (350 DEG C) generates substantial amounts of CO2、NH3、N2Non-flammable compressive gases are waited, dilute surface oxygen concentration, but it is anti-
Molten drop is poor, only source of the gas, lacks acid source and carbon source, when causing melamine cyanurate dosage larger, just has certain fire-retardant
Effect.
Graphene fire retardant is more for polyamide fibre composite material at present, but for spinning-grade nylon fiber material compared with
Few, main cause is：
1st, existing fire retardant additive amount is big, and the physical mechanical property decline of nylon fibre is larger.
2nd, the Graphene fire retardant of blending method addition and the compatibility of polyamide fibre are poor, easy fracture of wire in spinning process；
3rd, the Graphene fire retardant of copolymerization method addition, compatibility is better than blending method, complicated for operation but there are industrialized productions
Problem.
