Abstract
The invention relates to a method for preparing flame-retardant silk. A technical problem needing to be solved by the method is to improve the flame-retardant capability of the silk. The preparation method comprises the following steps: the silk is submerged in a flame retardant treatment solution in an oscillating sealed water-bath container, wherein the bath ratio of the silk to the flame retardant treatment solution is 5-20:1; when the sealed container is heated to 50 to 60 DEG C, a potassium persulfate solution is added in the flame retardant treatment solution, and the mass of the potassium persulfate solution is 2 to 5 percent of that of the flame retardant treatment solution and the concentration of the potassium persulfate solution is between 1 and 5 percent, the mixed solution isheated to 80 to 90 DEG C, and then is insulated for 2 to 4 hours; and after thermal insulation is over, the silk is taken out, washed with soap liquid, washed with water, rinsed and dried. The components of the flame retardant treatment solution by weight percentage are: 5 to 30 percent of methacrylate acyl-oxygen ethyl dimethyl phosphate and the balance being purified water. Formic acid is used for regulating pH value to between 3 and 5. The soap liquid is an alkyl benzene sulfonate solution, a fatty alcohol sodium sulfate solution or an alkyl sodium sulfonate solution.
Description
Technical field
The present invention relates to a kind of preparation method of flame-retardant silk.
Background technology
According to statistics, the fire that is caused by textiles accounts for 50% of annual fire sum.Textiles directly contacts with human body mostly, in case catch fire, the little human body skin that then makes is partly burnt, threat to life greatly then, and therefore, the anti-flammability that improves textiles has crucial meaning to the protection people life property safety.Britain has just implemented the premises fabrics flame resistance and has handled rules from 1989.The U.S., Japan then force legislation, require the import textiles need reach MIN fire-retardant, children below 6 years old and more than 60 years old old man's clothes reach moderate fire-retardant.
Real silk is because its soft natural gloss, exclusive scrooping feel, good health care and comfortableness and liked by the consumer, and China is that the cocoon silk quilt of raw material manufacturing all occupies big share in bed necessaries market at home with silk.
At present, known cocoon silk quilt main raw material is a silk etc.Correlative study shows that this class silk is when doing testing vertical flammability, and igniting 15s just burns up fully with interior.And used medicine is generally Chinese herbal medicine in the medicine cocoon silk quilt, is inflammable articles.Because cocoon silk quilt directly contacts with human body mostly, the cocoon silk quilt that the silk that using does not have anti-flaming function is made, security relatively is short of.Thereby it is carried out flame treatment research, to improving its security against fire performance, reach the right property detection index request of cocoon silk quilt outlet resistance and have crucial meaning.At present, the also unprecedented report of Chinese patent.
Summary of the invention
The technical issues that need to address of the present invention are to improve the firing resistance of common silk.
The preparation method of flame-retardant silk of the present invention, it is characterized in that in vibration sealing water bath containers, with the silk fire-retardant treatment liquid that submerges, its bath raio is 5 :～20:1, airtight container, when being warming up to 50～60 ℃, the concentration that adds fire-retardant treatment liquid quality 2～5% is the potassium persulfate solution of 1～5% (being preferably 3%), is warming up to 80～90 ℃ of insulations 2～4 hours; After insulation finishes, take out silk and clean with soap lye, washing rinses, oven dry;
Described fire-retardant treatment liquid composition percentage by weight is: methylacryoyloxyethyl dimethyl phosphate 5～30%, and all the other are pure water; With first acid for adjusting pH value to 3～5;
Described soap lye is selected from alkyl benzene sulphonate sodium solution (being preferably 2% concentration), fatty alcohol sulphuric acid sodium solution, alkyl sulfonic acid sodium solution.Through after the flame treatment, methylacryoyloxyethyl dimethyl phosphate is contained on the silk surface, thereby has fire retardation.
The silk of the inventive method preparation also has good flame retardancy except keeping self premium properties, its limited oxygen index can be up to about 35%, and the long test of charcoal is also by the fire-retardant index request of country to textiles.The cocoon silk quilt of making of this silk also has good flame retardant property except that having the warming anti-mite of common cocoon silk quilt, promoting the health properties such as sleep, delay senility, and helps reducing personnel and property loss in the fire.
The specific embodiment
Embodiment 1:
Fire-retardant treatment liquid is formed percentage by weight: methylacryoyloxyethyl dimethyl phosphate 15%, pure water 85%; It is 2% alkyl benzene sulphonate sodium solution that soap lye is selected concentration for use.
In vibration sealing water-bath, above-mentioned fire-retardant treatment liquid pH value is transferred to 4, silk is immersed wherein (bath raio is 10:1) under room temperature, be warming up to 50 ℃, the concentration that adds fire-retardant treatment liquid quality 2% is 3% potassium persulfate solution, is warming up to 80 ℃ of insulations 2 hours.After insulation finishes, take out silk, soap, washing, oven dry.To make the silk core as stuffing through the silk of flame treatment, with constituted fire-retardant health-care silk quilt by overcoat.This cocoon silk quilt limited oxygen index can reach 27%, and limited oxygen index belongs to the firing-difficult matter product between 26～34%, and as seen this cocoon silk quilt fire resistance is good, and is nonflammable.
Embodiment 2: fire-retardant treatment liquid is formed percentage by weight and is: methylacryoyloxyethyl dimethyl phosphate 30%, pure water 70%.It is 3% alkyl sulfonic acid sodium solution that soap lye is selected concentration for use.
In vibration sealing water-bath, above-mentioned fire-retardant treatment liquid pH value is transferred to 4.5, silk is immersed wherein (bath raio is 15:1) under room temperature, be warming up to 50 ℃, the concentration that adds fire-retardant treatment liquid quality 3.5% is 3% potassium persulfate solution, is warming up to 85 ℃ of insulations 3 hours.After insulation finishes, take out silk, soap, washing, oven dry.To make the silk core as stuffing through the silk of flame treatment, with constituted fire-retardant health-care silk quilt by overcoat.This cocoon silk quilt limited oxygen index can reach 34.5%, and limited oxygen index is belonging to the incombustible product more than 35%, this shows that this cocoon silk quilt approaches the incombustible product, has greatly improved its security against fire performance.
