Abstract
The invention discloses a method for preparing hemostatic sponge by use of sisal cellulose oxide. The method comprises the following steps of: performing basic boiling of the sisal fiber waste by use of sodium hydroxide solution, washing to neutrality, and drying and crushing to obtain powder; adding the powder of the sisal fiber waste to the sodium periodate solution with adjusted pH, and stirring for reaction at constant temperature; after the reaction is over, adding ethylene glycol solution and continuing stirring; filtering, washing the filter cake with distilled water to neutrality, and drying to obtain the sisal cellulose oxide; preparing the mixed solution of sodium hydroxide and thiourea; adding the prepared sisal cellulose oxide to the mixed solution for low-temperature dissolution; adding the pore-forming agent sodium sulfate, stirring uniformly and adding absorbent cotton; after low-temperature ageing, performing regeneration reaction in the coagulating bath formed by concentrated sulfuric acid and sodium sulfate; and washing clean with water to obtain the hemostatic sponge. According to the invention, the sisal cellulose oxide sponge is prepared by use of sisal fiber waste, and the obtained sisal cellulose oxide sponge has good antibacterial activity and can be used as hemostatic sponge.
Description
Technical field
The present invention relates to a kind of preparation method who utilizes the SURGICEL styptic sponge, particularly utilize sisal fibers waste such as numb chaff and the numb first-class method for preparing the plain styptic sponge of oxidation sisal fibers.
Background technology
Sisal hemp is the plain crop of a kind of leaf fibres of Agavaceae Agave, originates in the Mexican Long Jiadan peninsula.Mainly grow in the Lezhou Peninsula and some areas, Guangxi in China.
Numb chaff, numb first-class waste that sisal fibers produces in the course of processing as if it directly being discharged or stacking, not only cause the waste of resource, and can pollute environment.The plain styptic sponge of sisal fibers be with sisal fibers waste such as numb chaff, fiber crops are first-class is basic raw material; The porous cellulose product for preparing through certain method, be used for replacing traditional sponge; Have the characteristics such as air-dry, durable, that wiping effect is good, water-retaining capacity is strong, biocidal property and waste be biodegradable by force that are prone to; And environment is not had any pollution, both can be used as cleaning and wiping that general cleaning supplies are used for the kitchen, can be used for medical treatment yet and go up hemostasis wrapping etc.
Loft is good, advantages such as quality is soft, good water absorption are used widely because of having for sponge, but the chemical ingredients of general sponge is materials such as PS, urethane.No matter the preparation of this type material still is that technology is seen from raw material, all can produce human body and the deleterious material of environment, runs counter to the theory of human environment protection and Sustainable development.The premium properties that utilizes the Mierocrystalline cellulose styptic sponge of sisal fibers waste preparation not only to have traditional sponge also have good bacteriostasis property and abandon after can under microbial process, be decomposed into micromolecular compound rapidly and degrade.Under the situation that reserves descend day by day, industrial chemicals is in short supply of current oil and coal, utilize Mierocrystalline cellulose to replace traditional industrial chemicals to produce novel daily product, crucial meaning is arranged.
Summary of the invention
The objective of the invention is provides a kind of cellulose castoff such as numb chaff and numb first-class method for preparing the Mierocrystalline cellulose styptic sponge that stays in the sisal fibers production process of utilizing to above-mentioned situation.
Concrete steps are:
(1) use concentration the sisal fibers waste to be carried out the soda boiling pre-treatment, to remove pectin and xylogen wherein as the sodium hydroxide solution of 120g/L～180g/L;
(2) the sisal fibers waste after step (1) is handled is washed to neutrality, dry, pulverize the plain waste powder of sisal fibers;
(3) in filling the brown there-necked flask of 300ml zero(ppm) water, add the sodium periodate wiring solution-forming of 18g～30g while stirring, regulate between pH to 1～4 with dilute sulphuric acid when its temperature is controlled at 20 ℃～28 ℃;
(4) in step (3) gains, add fast the sisal fibers waste powder that makes in about 9g～15g step (2), elevated temperature to 30 ℃～45 ℃, the constant temperature stirring was reacted in 4～8 hours;
(5) finish the analytical pure ethylene glycol solution that the back adds 6ml～12ml at above-mentioned (4) reaction soln, continue to stir 1 hour, obtain tawny turbid solution;
(6) the isabelline turbid solution with (5) gained filters with B, and filter cake is washed with distilled water to neutrality repeatedly, and it promptly is that the oxidation sisal fibers is plain that oven dry obtains pale brown toner end;
(7) in 100ml zero(ppm) water, add the sodium hydroxide of 8g～12g and the thiocarbamide of 6g～8g and get mixing solutions; The oxidation sisal fibers that in mixing solutions, adds preparation in 6g～8g step (6) is plain; Place under-12 ℃～-20 ℃ the temperature and dissolved 6～8 hours, obtain the plain viscous solution of oxidation sisal fibers;
(8) in step (7) gains, add the pore former sodium sulfate of 28g～32g, the back that stirs adds 1g～3g absorbent cotton, under-12 ℃～-20 ℃ condition aging 3～5 hours;
(9) in 100ml zero(ppm) water, adding 3ml～4.2ml massfraction is that the sodium sulfate of 98% the vitriol oil and 3.5g～5.5g forms precipitation bath; With step (8) gains put into above-mentioned precipitation bath and under 60 ℃～65 ℃ temperature manipulation of regeneration 1～3 hour, totally can obtain the plain sponge of oxidation sisal fibers with distilled water flushing at last; Because of having strong biocidal property, it can be used as the Mierocrystalline cellulose styptic sponge.
The present invention utilizes the sisal fibers waste to prepare the plain styptic sponge of sisal fibers, to reach the purpose of comprehensive utilization sisal hemp waste.
