Description
The present invention relates to be used for the mechanical woven fabric used for radiation protection field.
Radioactive substance has fission character, can give off α, β, gamma-rays by cooling, their energy loss victimization soma and organs, thus cause various diseases even death.Along with the development and the increasingly extensive application of radio isotope of atomic energy industry, press for the material that can protect the radioactive substance irradiation.At first adopt the big material of density to shield in the prior art, protect the irradiation of radioactive substance, for example use lead, lead glass, lead rubber, cement, sandstone etc.Wear apron,lead personnel near radioactive source work, wear lead gloves, can play radiation-resistant effect, but leadwork is too heavy after all, pressing to such an extent that directly do not rise and work under the situation of waist and will soon tiredly can't bear, and if in the open air, more be not easy to action when working on the mine.In order to protect the radioactive substance irradiation, in the operating room, shield, but plumbous oxide is poisonous with stereotype.
The object of the invention be to provide a kind of protect the radioactive substance irradiation, can make clothes or paste on the wall the woven cloth of safety non-toxic.
Study for many years by the inventor, spraying is by barium sulfate (BaSO on the white lining cloth of textile microgroove
4) 45～60(weight) %, molybdenum bisuphide 15～25(weight) %, magnesium sulfate (MgSO
47H
2O) 4～6(weight) %, rubber adhesive (JFD) 14～18(weight) %, bleeding agent (JFC) 1～5(weight) % and softener (ES) 2～7(weight) the radiation proof composition formed of %, tie, dry and bake through partial desiccation, pressure then, make Antiradiation protection cloth.
Now Antiradiation protection cloth of the present invention is elaborated.
Because fabric can be made the clothes or the radome of different shape, so as long as can just can use with the material that radiation proof also can be bonded on the fabric in coating on the fabric for the irradiation of protection radioactive substance.Square being directly proportional of the shielding rate of considering radiation and shielding material density is so should select the big element compound of density.Barium is periodic table second main group (II A), atomic weight is 137.34, but the compound of all barium is all poisonous, be unsuitable for for Antiradiation protection cloth and use, having barium sulfate only is the white powder non-toxic compound of heavy, its proportion is 4～4.5, water insoluble, can stop x ray and shielding α, β, gamma-rays is so select the main composition of barium sulfate as radiation proof composition of the present invention, when its content less than 45(weight) during %, shielding property is relatively poor, and greater than 60(weight) during %, its poor adhesive force on fabric, powder will fall down, and be 45～60(weight so select the content of barium sulfate for use) % is advisable.
Because when list makes up owner's composition with barium sulfate as radiation proof, relatively poor to Beta-ray protection, and molybdenum has good screening ability to the β ray, molybdenum is periodic table the 6th subgroup (VIB) metallic element, its atomic weight is 95.94, molybdenum bisuphide is as the compound of molybdenum, the stable chemical performance acid and alkali-resistance, the radiation proof of the same energy with lead, but the toxicity resemble lead oxide does not exist, so select the second main composition of molybdenum bisuphide for use as radiation proof composition of the present invention, when its content less than 15(weight) %, shielding property is relatively poor, but as content greater than 25(weight) during %, the radiation proof composition is relatively poor to the adhesiveness of fabric, so the content range of selection molybdenum bisuphide is in 15～25(weight) %.
Magnesium sulfate is to contain the hydrate (MgSO of seven crystallizations water
47H
2O) use, magnesium sulfate can generate water-fast barium sulfate with the soluble barium salt, thereby removes the toxicity that is contained in the poisonous soluble barium salt in the barium sulfate, makes it become nontoxic barium sulfate, general its content is in 4～6(weight) % just can achieve the goal, and is useless at most.Other rubber adhesive (JFD), bleeding agent (JFC) and softener (ES) all are assistants habitual in textile industry, on market, can buy, their content is respectively in 14～18(weight) %, 1～5(weight) % and 2～7(weight) %, their effect is with Radioprotector compounds such as barium sulfate, the hydrate of molybdenum bisuphide and magnesium sulfate is bonded on the fabric, make said Radioprotector compounds permeate among fabric fibre and make it soft, in a word, aftermentioned is the additive that improves fabric property commonly used in textile industry for three kinds, and they all are no toxicants.
The white lining cloth of textile microgroove that process has sprayed radiation proof composition of the present invention is made Antiradiation protection cloth again through following operation:
Partial desiccation is that the cloth that has sprayed the radiation proof composition is passed through in 60～80 ℃ hothouse, only reach partial desiccation, so that following pressure knot operation, pressing knot is that half-dried Antiradiation protection cloth is passed through in two rollers, Radioprotector compounds tightly is bonded on the cloth, and then makes hothouse, make its drying by 60～80 ℃, baked 4～8 minutes in that 120 ℃ bake is indoor at last, promptly can be made into Antiradiation protection cloth.
Lift an embodiment of the invention now:
Spraying is by barium sulfate 50(weight on the white lining cloth of textile microgroove) %, molybdenum bisuphide 20(weight) %, magnesium sulfate (MgSO
47H
2O) 5(weight) %, rubber adhesive (JFD) 16(weight) %, bleeding agent (JFC) 4(weight) % and softener (ES) 5(weight) the radiation proof composition formed of %, then through half-dried under 70 ℃, press knot, 70 ℃ down dry and under 120 ℃, baked 5 minutes, make Antiradiation protection cloth.
Antiradiation protection cloth of the present invention was tested through packet header Institute of Metallurgical Technology of Ministry of Metallurgical Industry in May, 1985: in anti-alpha ray test, use FJ335D type α, β measuring instrument, use alpha probe, radioactive source is the natural uranium standard source, radioactive source and counting tube distance are 1.5 centimetres, after survey in 10～20 minutes is looked, record its α absorptivity more than 90%, can make the α population that sees through drop to background level; In anti-β ray test, still use above-mentioned instrument, but use beta probe, use
90Sr large tracts of land β standard source, distance is 2 millimeters and other different distance, records its β absorptivity more than 34%, and tangible absorption is arranged; In the anti-gamma-ray test, use FJ-317C type γ measuring instrument, use
60Co,
241Am and
137Cs is a radioactive source, to the low-grade energy gamma-rays for example
241The Am absorptivity can reach more than 30%, to the higher gamma-rays of energy (for example
60Co) absorptivity can reach more than 50%.
Hubei Province Puqi City boats and ships research institute is using the infrared inspection weld seam, be worn in staff's coat pocket after being placed on the two-phase photoplate in the special box, through after the certain hour, taking-up is carried out developing fixing to it and is handled, find that its amount of radiation surpasses 400 times of human body acceptable dose, and be installed with behind the Antiradiation protection cloth of the present invention made Work Clothes, its photoplate of wearing after treatment, its dosage of radiation is fully in ensureing the human body safe range.
Can protect radioactive substance irradiation and can make clothes or be attached to wall from the visible Antiradiation protection cloth of the present invention of above test and protect, safe and nontoxic.
