Description
Technical field
The present invention relates to a kind of fibroin composite coating liquid and preparation method thereof and application.
Background technology
Fibroin contains 18 seed amino acids, and wherein glycine, alanine, serine account for more than 70%, is functional outstanding nutrient substance, is widely used in medicine, food, cosmetics, leather and fabric etc.Daily-use sanitary parent skin articles for use (sanitary towel, protective pad, diaper, cotton pads etc.) market potential is huge.Containing abundant serine and threonine in the fibroin, is natural and the affine nutrient substance of human skin; And fibroin contains very abundant polarity side an aromatic plant metioned in ancient books aminoacid, and NMF content is abundant, has fine water absorption, wet putting and moisture retention, can regulate the skin trophic function; Simultaneously, discover that fibroin to itching of causing of weather or human body particularity and eczema has preventive and therapeutic effect, has antibacterial characteristics.Based on the characteristics of fibroin, be applied to the production of health parent skin articles for use, will have than existing product that close skin is comfortable, the protection skin, breathability, hygroscopicity is strong, the top layer is dry and comfortable and anti-inflammation, prevent the advantage of dermatosis.At present, do not see that yet the silkworm silk series products is used to prepare the coating liquid of woman, baby, child parent skin articles for use.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of fibroin composite coating liquid is provided.
Another object of the present invention is to provide the preparation method of this fibroin composite coating liquid.
The present invention also has a purpose to be this fibroin composite coating liquid is applied to producing of woman, baby, child's parent's skin articles for use.
For achieving the above object, the present invention has taked following technical scheme:
Fibroin composite coating liquid by weight percentage, is made of following material:
Cross-linking agent: 2～10% acetic acid: 0.5～2%
Fibroin: 10～20% all the other be water.
In the technique scheme, described fibroin is the water-solubility protein that comprises silk peptide, silk essence, sericin, comprises the water-insoluble fibroin of fibroin, or the nanometer fibroin; As preferably, described nanometer fibroin is the nanometer fibroin of granule in the 1000nm-1nm scope.
In the technique scheme, described cross-linking agent is Pupa bombycis chitosan (chitosan), chitosan (deacetylation chitin) or hydrocarbyl si lanes compounds and catalyst ZnCL
2Complex.
In the technique scheme, the preparation process of described Pupa bombycis chitosan is as follows:
(1) decalcification: in dried Pupa bombycis shell: the hydrochloric acid of 3-5% weight concentration is 1: 15～20 ratios batchings; Earlier 3-5% hydrochloric acid is added acid-resistant tank, drop into the Pupa bombycis shell then and stir repeatedly, make it even; Soak after 20-24 hour and to take out, in the acid of desalting of plastic filter screen upward filtration; Wash shell from the beginning to neutral; Dry with centrifuge, put into the drying room oven dry, temperature 70-80 ℃;
(2) refining is boiled: by the dried shell of decalcification: the caustic lye of soda of 5-10% weight concentration is 1: 20 part by weight, drops into enamel reaction still, is warming up to boiling, starts blender, boils to boil to stop heating in 2-4 hour, cools off, and blowing is gone into drainage screen, and shell leaches.With the tap water flushing, identical until the washing liquid color with tap water, dry with centrifuge, put into the drying room oven dry, bake out temperature is 70-80 ℃; Moisture content takes out less than 10%, gets the crude product chitin;
(3) chitin is refining: by the crude product chitin: the w/v of the potassium permanganate solution of 0.5-1% weight concentration is that 1: 20 prescription decolours; At room temperature stirred 0.5～1 hour, and poured cloth bag elimination potassium permanganate liquid into, and use pure water rinsing, be washed till that to extrude liquid identical with the pure water color, dry, survey moisture content with centrifuge;
(4) chitosan is produced: by chitin: the w/v of 35-45% weight concentration NaOH aqueous solution is 1: 20 a prescription, drops into enamel reaction still, and warming while stirring is warming up to boiling, and temperature is controlled at 110 ℃-120 ℃; Seething with excitement stops heating after 4-6 hour, with acidproof filter screen elimination high alkali liquid, pure water washing again is until no phenolphthalein reaction; Centrifuge dries; 10 times of volumes of ethanol with 95% soaked 10 hours, leached ethanol, and centrifuge dries, and puts into the drying room drying, temperature 70-80 ℃; Moisture content can take out cool cold below 8%.
The preparation method of fibroin composite coating liquid comprises following technical step:
(1) fibroin produces
(a) with tap water silkworm silk was soaked more than 12 hours, the reuse pure water cleans 3～5 times, uses centrifuge dewatering, surveys moisture content;
(b) by silkworm silk: the weight ratio of water is that 1: 6～10 bath raio is put into the still that comes unstuck with silkworm silk and water, under 0.1～0.2mpa steam pressure, comes unstuck 0.5～2 hour, pulls fibroin out, cleans in pure water, uses centrifuge dewatering, surveys moisture content;
(c) be immersed in the NaOH aqueous solution of 4～6% weight concentrations 20～30 hours by natural silk; Natural silk: the weight ratio of NaOH aqueous solution is 1: 10～12;
(d) soaked after, in above-mentioned solution, add the sulfuric acid solution neutralization of 10% weight concentration, to PH be 5～7;
(e) use centrifuge dewatering, put into drying room, bake out temperature is 70-80 ℃, dry by the fire to moisture content less than 10%;
(f) pulverize 3-5 time with accurate pulverizer; Soluble in water the powder after pulverizing with the NF membrane filtration, make fibroin particle diameter≤400mm; The reuse centrifuge dewatering is put into the drying room oven dry, and temperature is controlled at 70-80 ℃, and moisture content takes out cool cold less than 8%;
(2) fibroin composite coating liquid is produced
Water is warmed up to 60-90 ℃, adds 2-10% cross-linking agent and 0.5-2% acetic acid, stirred 0.5～3 hour; The fibroin that adds 10-20% again stirs well, and gets coating liquid.
In the technique scheme, described fibroin composite coating liquid is used for producing of woman, baby, child's parent's skin articles for use.
Compared with prior art, the present invention has following beneficial effect:
1. fibroin of the present invention has abundant nutritive value, usually as the nourishing additive agent of food, health product, cosmetics, in the research and development of more than ten years, we find that fibroin not only has higher nutritive value, and having Glycerin, control is caused a disease and is pressed down the effect of oxygen bacterium, acid-producing bacteria.Apply woman, baby, child's articles for use with fibroin and can solve because of dermatosis and pudendal infection such as the allergy that articles for use material reason causes, wet diseases, make they with after dryer and comfortableer, grow skin, joyful.
2, the present invention utilizes chitosan cation group characteristic and fibroin albumen, sericin polar group characteristic how to carry out crosslinked coating, has realized green, natural crosslinked prescription, the craft science uniqueness.
3. preparation technology of the present invention is simple, easy to operate, and the utilization scope is wide, and is effective;
4. fibroin of the present invention has effects such as the skin moistening of pure natural, antibiotic, antiallergic, can be used for producing woman, baby, child parent skin articles for use, reaches Glycerin, and moisture absorption is antibiotic, the purpose of control skin allergy;
5. the product that makes of the present invention has significant Glycerin, and moisture absorption is ventilative, prevents skin allergy, and bacteriostasis presses down the oxygen bacterium to causing a disease especially, and acid-producing bacteria has the obvious suppression effect.
