Increasingly higher demands, in order to assign cellulose fibre good flame retardant property, widen its application field, both at home and abroad it is many specially
Family scholar has conducted intensive studies cellulose fibre/fabrics flame resistance.
Traditional halogenated flame retardant is considered as efficient cellulose fire retardant, but halogenated flame retardant is using process
The toxic and corrosive substance of middle release makes it gradually be used by limitation.Instead halogen-free flame retardants.Halogen-free flame retardants
Mainly comprising phosphate, phosphate, phosphorus-nitrogen compound, phosphorus silicon compound, nitrogen silicon compound, silicon boron compound etc..Wherein, phosphorus nitrogen
System fire retardant is most effective cellulose fire retardant.At present, the cellulose of industrialization is with phosphorus nitrogen flame-proof finishing process
Pyrovatex CP techniques, using N- methylols -3- (dimethoxy phosphono) propionamides and crosslinking agent under acid catalysis with
Cellulose crosslinks reaction, obtains durable flame-retardant cotton fabric.But it is collated after fabric during storage and use
Free formaldehyde can be released.To find a kind of nontoxic halogen-free flame retardants, Chinese patent CN1362413A utilizes melamine and phosphorus
Acid etc. prepares a kind of melamine phosphate fire retardant, among the high molecular materials such as various thermoplasticity and thermosetting property, obtains
Good durable flame-proof material, however solubility is minimum in water is unfavorable for native cellulose and regenerated cellulose for prepared product
Fire-retardant application.
In conclusion the present invention devises the preparation side of a kind of phosphorus-nitrogen containing antiflaming finishing agent and flame retardant cellulose fiber fabric
Method.

Molar ratio is 1:6~12 proportioning is added in reactor, under the conditions of 30~100 DEG C reaction 3~12 it is small when, be made it is fire-retardant into
Divide phytic acid ammonium.
A kind of cellulose base fiber fabric for cotton, fiber crops, bamboo fibre, viscose rayon, copper ammonia fiber cellulose fiber,
Lyocell fiber and ionic liquid spin one kind in cellulose fibre/fabric.
A kind of cellulose base fiber fabric flame-retardant finishing method, comprises the following steps：Flame-proof treatment, which uses, pads-does
Dry-baking, wherein padding in step, dressing liquid temperature is room temperature~70 DEG C, and soaking time is 10~120 minutes；It is described
In drying steps, drying temperature is 80~150 DEG C, and drying time is 5~15 minutes；Described to bake in step, baking temperature is
160~200 DEG C, the time is baked as 2~20 minutes.
Described pad in step soaks two roll process using two, and immersion liquid rate is 80~150%.
The invention has the advantages that：By the present invention in that it is prepared by the use of phytic acid as raw material with nitrogenous compound fire-retardant
Agent phytic acid ammonium, phytic acid are a kind of natural materials of high phosphorus content, and will not generate any has human body and environment in use
Noxious material, avoiding problems in widely used fire retardant processing procedure in the market discharge noxious material the defects of.In addition,
It is fine which solves many flame-proof treatments since the special construction of phytic acid and its ammonium salt makes it form chemical bond with cellulose fibre
The problem of dimension/fabric is not water-fastness solves the problems, such as flame retardant cellulose fiber/fabric durability.
