Description
Technical field
The present invention relates to fiber production fields, synthesize more particularly, to a kind of milk protein modified acrylic fibre slurries
Technique.
Background technique
Milk protein modified acrylic fibre is a kind of side that milk casein (casein) is passed through graft copolymerization
Method grafts the new modified fiber of formation on polyacrylonitrile molecular side chain.In the patent 00116211.X delivered, by bone
Frame compound milk casein and acrylonitrile or acrylonitrile and vinyl unsaturated monomer are dissolved in liquor zinci chloridi, with oxidation
Reduction initiating system carries out graft copolymerization.Although the patent substitutes inorganic initiator using organic initiators, solves zinc chloride
The recycling problem of solvent and reduce environmental pollution.But since redox initiation system is made of two kinds of chemical substances,
It has the disadvantages that in the actual production process：1) more complicated for operation than single initiator；2) it adds speed and reaction rate is difficult to
Control；3) consumption is big, higher cost.
Summary of the invention
It is modified that it is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of milk proteins
Polyacrylonitrile fibre slurries synthesis technology.
The purpose of the present invention can be achieved through the following technical solutions：
Milk protein modified acrylic fibre slurries synthesis technology, using following steps：
(1) casein pre-processes：Casein is placed in urea liquid and carries out swelling pretreatment；
(2) polymerization process：The casein filtering of swelling is placed in solution, acrylonitrile is added and initiator is polymerize
Reaction, obtains milk protein modified acrylic fibre.
The concentration of urea liquid described in step (1) is 5-50wt%, and the mass ratio of casein and urea liquid is 1:20
~1:5, the temperature of swelling pretreatment is 25-95 DEG C, time 0.5-12h.
Solution described in step (2) is concentration 40wt% to saturation sodium thiocyanate solution, casein and sodium thiocyanate solution
Mass ratio be 3~15:100, the initiator is azodiisobutyronitrile, and the mass ratio of casein and acrylonitrile is 1~4:6~
9, the additional amount of initiator is 0.1~2wt% of solution total amount.
In former redox initiation system, using azodiisobutyronitrile as alternative initiator.Azodiisobutyronitrile is azo
Type radical initiator, azo-initiator stable reaction are first order reactions, and without side reaction, and medium temperature decomposes and is suitble to casein
Reaction, relatively good control, stabilization easy to operate such as use azo initiator, do not use other such as zinc chloride polar solvent, if made
It is acid too strong with the better solvent of polarity, it is easy to cause new decomposition of initiator, protein (casein) can also decomposed, this
Application is solved the above problems by using Sodium Thiocyanate Solvent to cooperate azodiisobutyronitrile.
It is more obvious using azo initiator advantage and fairly simple to the pretreatment of casein.Casein is isoelectric point
For the bisexual protein of pH4.8, exist in milk with the composite form of Dicalcium Phosphate, tricalcium phosphate or both, constructs pole
For complexity, up to now without completely specified molecular formula, molecular weight is higher, about 57000-375000.If the work by
Skill does not pre-process casein, then dissolubility of the casein in Sodium Thiocyanate Solvent is poor, will lead to polymerization reaction not
Thoroughly, the problems such as degree of polymerization and protein content of casein and acrylonitrile polymer are not easy to control, seriously affects aralac
Quality.It is pre- using urea by being pre-processed to casein for the use for cooperating the above azo initiator and dicyandiamide solution
Casein is handled, its swelling is made, and the macromolecular chain in protein is allowed to obtain softness and unfold.Then it enters back into solvent and neutralizes third
Alkene nitrile monomer is polymerize, to solve the problems, such as casein indissoluble in Sodium Thiocyanate Solvent.
Compared with prior art, the present invention has the following advantages that：
1, using a kind of initiator, cost is reduced；
2, azo-initiator stable reaction, without side reaction；
3, technique preferably controls, easy to operate；
4, unfold protein macromolecule sufficiently the pretreatment of casein, be easier to be polymerize with acrylonitrile monemer.
