Abstract
The invention relates to a synthesis process of graft copolymerized fiber slurry of collagen and acrylonitrile, the process comprises the steps of using a redox initiation system for carrying out graft copolymerization on a framework compound of the collagen and a first polymer monomer of the acrylonitrile or the first polymer monomer of the acrylonitrile and a second polymer monomer in concentrated zinc chloride water solution, wherein the redox initiation system is an organic substance, and the organic substance consists of an oxidant of organic peroxo acid and a reducing agent of glucose. Compared with the prior art, the synthesis process can greatly reduce the introduction of impurities in the zinc chloride solvent, be conductive to the recycling of the zinc chloride solvent, reduce the cost and reduce the environmental pollution.
Description
Technical field
The present invention relates to the polymerization of collagen protein and vinyl cyanide, especially relate to the synthesis technique of a kind of collagen protein and acrylonitrile graft copolymer fibre slurries.
Background technology
At present, collagen protein and acrylonitrile graft copolymer fibre slurries synthetic be with dense liquor zinci chloridi as solvent, under redox system caused, collagen protein and vinyl cyanide carried out uniform graft polymerization.In its redox system, oxygenant adopts ammonium persulphate, Sodium Persulfate, Potassium Persulphate, sodium chlorate more, and used reductive agent has the zinc sulfite of S-WAT, sodium bisulfite, potassium sulfite and invention afterwards etc.In above-mentioned redox system, no matter select which assembly to causing, reaction back system all can produce a large amount of sulfate anions and positively charged ions such as potassium, sodium, so also can cause adverse influence to the liquor zinci chloridi utilization regeneration as solvent.In suitability for industrialized production, must recycling as the zinc chloride solvent of main production cost, and at the inorganic impurity of non-native system that above-mentioned redox system is introduced, positively charged ion or negatively charged ion is when running up to some amount no matter, must influence the stability of slurries, so that have influence on the product quality of fiber.And in recovery operation, remove these impurity, then need huge and the complicated operations system.
Summary of the invention
Purpose of the present invention be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of cost low, pollute the few collagen protein and the synthesis technique of acrylonitrile graft copolymer fibre slurries.
Purpose of the present invention can be achieved through the following technical solutions: the synthesis technique of a kind of collagen protein and acrylonitrile graft copolymer fibre slurries, it is characterized in that, this technology be with framework compound collagen protein and the first polymerization single polymerization monomer vinyl cyanide or the first polymerization single polymerization monomer vinyl cyanide and second polymerization single polymerization monomer in dense solder(ing)acid, carry out graft copolymerization with redox initiation system, described redox initiation system is an organic substance, and this organic substance is made up of oxygenant organic peroxy scorbic acid glucose.
Described second polymerization single polymerization monomer is the vinyl unsaturated monomer with acrylonitrile compolymer, and in water soluble or the certain density liquor zinci chloridi.
Described second polymerization single polymerization monomer comprises methyl methacrylate or allyl sulphonic acid and salt thereof.
Described organic peroxide acid comprised oxy hexanoic acid, peroxyformic acid or peroxide trifluoro caproic acid.
The weight ratio of the described collagen protein and the first polymerization single polymerization monomer vinyl cyanide or the first polymerization single polymerization monomer vinyl cyanide and second polymerization single polymerization monomer is 1～4: 6～9.
The concentration of described solder(ing)acid is 40% to saturated (weight), and reactant is 3～15: 100 in the weight ratio of solder(ing)acid.
The weight ratio of described oxygenant organic peroxide acid and reductive agent glucose is 1: 0.1～1.
Described graft copolymerization reacted 0.5～24 hour under 0 ℃～60 ℃ and nitrogen protection.
Compared with prior art, therefore the present invention, just remain in the organic impurity of solvent as long as can finish by simple removal of impurities operation, handles ozone oxidation method etc. because the redox initiation system that uses is a organic substance by easy removal constitutes as activated carbon adsorption.And former known method, since the redox agent that uses all be contain sulfate radical, sodium ion, potassium ion, etc. inorganic substance, with general recycling and processing device, be difficult to removal at all, as not removing these impurity, can influence the stability of graft copolymerization again.So compared with former known any method, advantage of the present invention is tangible, use organic redox initiation system, substitute the graft copolymerization that inorganic redox initiation system carries out collagen protein and acrylonitrile monemer, the product quality of fiber will be better than the quality product that inorganic redox initiation system is produced.In addition, can significantly reduce the introducing of impurity in the zinc chloride solvent, help the regeneration of zinc chloride solvent, can reduce cost, reduce environmental pollution.
