Abstract
The invention discloses a medical fiber membrane for preventing X-rays. The technique for preparing the medical fiber membrane comprises the following steps: a viscose stock solution is uniformly mixed with rare earth carbonate particulates according to the mass ratio of 100 to 2 under the condition of 160 DEG C to obtain a mixed liquor, wherein the viscose stock solution is a sodium hydroxide solution containing cellulose sodium xanthate, and pure alpha-cellulose is extracted from a cellulose raw material, and is processed through caustic soda and carbon disulfide, so that the cellulose sodium xanthate in the sodium hydroxide solution is obtained; a defoaming agent is added into the mixed liquor; the mixed liquor is extruded from a spinneret orifice to form the mixed liquor trickle, and the primary raw silk is coagulated via the coagulating bath, wherein the coagulating bath comprises the following components: 90 g/L of H2SO4, 170 g/L of Na2SO4 and 85 g/L of ZnSO4; the primary raw silk is drawn to form a composite fiber filament. The medical fiber membrane disclosed by the invention can prevent irradiation of X-rays well, can be used for a protection suit of a sickroom, and causes no side effects to human bodies and the environment.
Description
Technical field
The present invention relates to a kind of medical fibre film for X-ray-preventing, belong to weaving face fabric technical field.
Background technology
Along with the raising day by day of people's awareness of safety, in world wide, the total flow of security protection series products is also the trend of increase year after year.Security protection fiber is one of important kind of security protection material, be widely used in the fields such as oil, chemical industry, metallurgy, shipbuilding, fire-fighting, army and have naked light, distribute spark, motlten metal and have the place of combustible material.Due to attention to dangerous operation place personnel safety guard of scientific and technological progress, expanding economy, particularly government, make security protection material all or part of employing new and high technology composite already.
By safeguard function, divide health type protection, as radiation proof, cold-proof, heat insulation and antibacterial etc.; Safety-type protection, as fire-retardant, antistatic, shellproof, anti-stab, acid-proof and insect protected etc.; For keeping the protection of health, as grease proofing, dustproof and refuse water etc.The material of protection, except meeting high-strength, high-anti-friction etc. requires, often different variant because of protection object, protection principle, generally there are the physics of defence, chemistry and biological etc.
Ray is just more and more paid attention to by people the harm of human body, and the staff under many specific work environments needs to dress special ray protective clothing.
In general, ray protection material, according to the kind of shielded ray, is also divided into two classes, one is X-ray protection material, main protection X ray gamma rays etc., another kind is the protective materials of common Non-ionizing radiation, is mainly used to protect electromagnetic radiation and part long wave ray.At present, X-ray protection material mainly uses the rubber of leaded (Pb) to make, and is used at present hospital radiological department, school laboratory, nuclear industry environment etc.
Lead belongs to heavy metal has very large harm to human body.Lead can not be decomposed in water, and people drinks rear toxicity and amplifies, and other toxin in water are combined and are generated the larger organic matter of toxicity.Lead is generally extensively present in occurring in nature with natural concentration, but because exploitation, smelting, processing and the business manufacturing activities of the mankind to heavy metal is increasing, causes many lead to enter in atmosphere, water, soil, causes serious environmental pollution.The heavy metal that human injury exists with various chemical states or chemical form will retain, accumulates and move after entered environment or the ecosystem, works the mischief.Plumbous: to be the one that heavy metal pollution Poisoning is larger, once entering human body will be difficult to get rid of, the directly brain cell of harm people, the particularly nervous system of fetus, congenital feeblemindedness can be caused, people's headache, dizziness, insomnia, forgetful, refreshing smart entanglement, arthralgia, calculus, cancer can be caused.Plumbous pollution problem is more and more paid attention in China.
Summary of the invention
The object of the invention is to provide a kind of medical fibre film for X-ray-preventing, and this medical fibre film can well prevent the irradiation of X ray, can be used for the protective clothing in ward, and has natural degradable function, and human body and environment are all free from side effects.
For achieving the above object, the technical solution used in the present invention is: a kind of medical fibre film for X-ray-preventing, and the described medical fibre film for X-ray-preventing obtains by following process, and this comprises the following steps process:
Step 1, viscose glue stoste and rare earth carbonate particulate are evenly mixed under 160 ℃ of conditions to acquisition mixed liquor by the mass ratio of 100:2, this viscose glue stoste is the sodium hydroxide solution that includes sodium cellulose xanthate, and in sodium hydroxide solution, sodium cellulose xanthate is by being extracted pure alpha-cellulose, processing and obtain with caustic soda, carbon disulfide by cellulosic material;
Step 2, defoamer is added to the mixed liquor through step 1, in order to remove the foam in mixed liquor;
Step 3, the mixed liquor obtaining is cooked to further filtration;
Step 4, the mixed liquor of step 3 is extruded and formed after mixed liquor thread by spinneret orifice, then through 90～95 ℃ of coagulating baths, this mixed liquor thread is frozen into spun filament, this coagulating bath comprises following component:
H
2SO
4 90g/L，
Na
2SO
4 170g/ L，
ZnSO
4 85g/ L；
Step 5, the spun filament of step 4 is carried out to drawing-off form composite fibre long filament;
In described step 2, defoamer is silicone defoaming agent, and addition adds 0.05 ~ 0.10% after pressing 1:6 dilution.
As preferably, between described step 1 and step 2, be provided with filtration treatment, for the larger particle of filtering and impurity.
As preferably, the time of stirring while evenly mixing in described step 1 is 60min.
As preferably, in described step 5, the extensibility of drawing-off is 15～20%.
Because technique scheme is used, the present invention compared with prior art has following advantages and effect:
The present invention is for the medical fibre film of X-ray-preventing, and it makes cotton sheet through nonwovens process, cotton sheet is placed on and on X ray test instrument, tests its lead equivalent, its test result: lead equivalent is 0.63mmPb.(the protection highest level III of X-ray protection clothes requires lead equivalent >=0.50mmPb), can be found out by above-mentioned test result, the composite of making by the method has the function of good X-ray-preventing; Secondly, because two main raw material viscose glue stostes of the present invention and rare earth carbonate are all natural natural components, there is natural degradable function, human body and environment are all free from side effects.
