Description
Technical field
The present invention relates to fabrics flame resistance final finishing technical fields, and in particular to a kind of durable flame-proof fabric finishing liquor and durable
The preparation method of flame-retardant textile.
Background technique
Being usually used in the fire retardant of fabrics flame resistance final finishing at present is mainly inorganic fire retardants (such as aluminium hydroxide, magnesium hydroxide
Deng), halogenated flame retardant, phosphorus flame retardant etc., wherein inorganic fire retardants flame retarding efficiency is lower, to the adhesive force on fabric fibre surface
It is poor；Halogenated flame retardant pyrolysis release nocuousness, toxic gas, easily cause secondary injury, so that inorganic fire retardants and halogen system are fire-retardant
Agent is limited in the application of textile finishing flame retardant area.Organic phosphorus flame retardant mostly has many advantages, such as low cigarette, nontoxic, low halogen, Halogen,
With good development prospect.
DNA (DNA) is by pentose, nitrogenous base (including adenine, guanine, cytimidine, thymidine)
And phosphate group etc. composition, be the chief component of chromosome, be widely used in biological inductor and medicine preparation and
Environmental monitoring etc..In recent years, the long-chain polymer structure based on DNA containing a large amount of phosphorus, nitrogen, domestic and international researcher begin trying
Using pad, DNA final finishing in fabric fibre surface, is effectively improved its flame retardant property by LBL self-assembly (LBL) technique, act on
Mechanism mainly passes through: (1) a large amount of phosphorus, nitrogen play the role of cooperative flame retardant in combustion in DNA, and phosphate group is as acid
Source promotes to form heat-insulated carbon-coating under high temperature in polymer surfaces, and nitrogen-containing group can not combustion gas as release in gas source pyrolytic process
Body promotes thermal insulation layer foaming and intumescing, ultimately forms expansion carbon-coating, effectively completely cuts off mass exchange and heat exchange, to obtain good
Flame retardant property；(2) depolymerization forms and single-stranded need to absorb amount of heat (related data is shown under DNA molecular double-spiral structure high temperature
Caloric receptivity is up to 18000kcal/mol), further increase its flame retarding efficiency.Therefore DNA is a kind of efficient, environmentally friendly, resourceful
Green-fabrics finishing fire retardant, though will in the research of DNA flame-retardant after-finishing fabric find DNA molecular can improve fabric
Combustibility, but DNA mainly passes through electrostatic force and Van der Waals force is attached to fabric surface, for several times anti-flammability after washable test
It can decline obviously, almost lose flame retardant property after 20 washings, durability of fire-retardant is poor, therefore has limited to such green-fabrics environmental protection
Antiflaming finishing agent is preparing flame-retardant curtain, clothes, and the actual use in the products such as sofa cloth greatly limits DNA after fabric
Arrange the application and popularization in flame retardant area.
