Abstract
The invention discloses flame-retardant animal protein artificial hair and a preparation method thereof. The flame-retardant animal protein artificial hair of the invention mainly comprises a chemical cross-linking agent and chemically-modified mixed protein; the mixed protein is prepared mainly by animal protein, ethylene monomers and a fire retardant. The fire retardant is a red phosphorus microcapsule or pentabromodiether; the animal protein is keratin, collagen or a mixture of the two. According to the invention, the protein artificial hair is provided with flame retardancy, and thus the safety of wig modification objects is improved.
Description
Technical field
The present invention relates to a kind of flame retardant type artificial hair made from animal protein, and the preparation method of this artificial hair.
Background technology
The people sends out resource scarcity, and rise in price is very fast, can not satisfy the raw material demand of hair product industry.The protein artificial hair has emulation property preferably.It can partly replenish in short supply that the people sends out.But most protein artificial hairs are inflammable.Therefore fire-retardant upgrading becomes pressing for of consumer.
Summary of the invention
The technical issues that need to address of the present invention are to disclose a kind of flame retardant type artificial hair made from animal protein, to overcome the flammable defective that prior art exists.
Another purpose of the present invention is to provide a kind of preparation method of flame retardant type protein artificial hair.
Technical scheme of the present invention: a kind of flame retardant type artificial hair made from animal protein preparation method; Water-fast fire retardant is added in the spinning slurry of graft copolymerization of protein and vinyl-type monomer and stirs; Filter impurity elimination; Remove bubble, leave standstill the back adopt wet spinning and post processing process finished product.
Further; The object of the present invention is to provide a kind of spinning slurry that the flame retardant type artificial hair made from animal protein is used for preparing, it is characterized in that: said spinning slurry mainly contains vinyl graft copolymer and the spin solvent and the initator of fire retardant, protein.
Said fire retardant is microcapsules or the decabromodiphenyl oxide that contains red phosphorus, and it accounts for the 1-10wt% of contained total solid in the spinning slurry.
Said protein is one or both mixtures in keratin protein, the collagenic protein.
Said vinyl-type monomer is a kind of in acrylonitrile, methyl methacrylate, butyl methacrylate, the vinyl chloride or 2 kinds.
Total solid is the term in the wet spinning, is meant the total amount of the solids after spinning slurry solidifies, and it comprises the total amount of the protein solid, additive, colorant etc. of chemical modification.The total solid method of testing: take by weighing 0.1000 gram spinning pulp, be tiled on the glass plate, this glass plate is dipped in the distilled water, treat that spinning pulp is solidified after, epistasis comes off from glass plate automatically, weigh W gram of oven dry epistasis, total solids content=W/0.1000 * 100%.
A kind of flame retardant type artificial hair made from animal protein preparation method, concrete steps are:
(1) animal protein is dissolved in the spin solvent; Add vinyl-type monomer and initator then; Solution is heated to 50-80 ℃, when being reacted to 3rd hour, adds fire retardant, react to stop after 4-5 hour heating and be cooled to 35 ℃; Vacuumize and remove residual vinyl-type monomer, it is for use to process spinning slurry;
(2) spinning slurry that step (1) is made carries out wet spinning, and during wet spinning, above-mentioned spinning slurry is extruded from spinneret cap, in coagulating bath, is frozen into tow;
(3) with after the washing of above-mentioned tow, in boiling water stretching 3-6 doubly, the tow after the stretching is relaxation processes in 110-135 ℃ of hot blast;
(4) tow after drawn, the relaxation processes being dipped in concentration is that 2-10%, temperature are to do chemical crosslinking in 90-99 ℃ the hydrazine hydrate aqueous solution to handle 2-3 hour, washing then, and last silicone oil, oven dry must products.
The adding of vinyl-type monomer described in the step (1) is in batches or disposable adding.The addition of vinyl-type monomer with the ratio of the addition of protein is: 1: 0.1-10.
Above-mentioned initator is azodiisobutyronitrile or ABVN, and its addition is the 0.02-1.5% of vinyl-type monomer weight.
The vinyl graft copolymer of protein content in spinning pulp is 5-14wt%.
The micro-pore diameter of the spinneret cap of used wet spinning is 0.35-0.45mm.The aperture is prone to during less than the 0.35mm spinning stop up; The aperture is greater than 0.45mm, and then flow is too big, the measuring pump supply bottleneck, and pipe diameter is limited, can't bear load.
Used spin solvent is sodium thiocyanate water solution or solder(ing)acid.The concentration of sodium thiocyanate water solution is 48-56wt%; The concentration of solder(ing)acid is 55-66wt%.
The coagulating bath concentration of wet spinning has considerable influence for the flexibility of artificial hair.As far as sodium thiocyanate water solution, solidification liquid concentration is advisable with 20-30wt%, the too low hair embrittlement of concentration; Excessive concentration is then solidified too fast, can not ordinary production.As far as solder(ing)acid, solidification liquid concentration is advisable with 20-40wt%, and concentration is too low, the hair embrittlement.
Coagulation bath temperature is advisable with 10-25 ℃, and temperature is too high, and the too fast cortex of hair shaping breaks; Temperature is too low, and energy consumption is too big.
Beneficial effect: a kind of flame retardant type artificial hair made from animal protein provided by the invention, it has flame retardancy, increases the security of wig trim.
