Abstract
The invention discloses glue for a nuclear-radiation shielding lead garment and a production method thereof, relating to a nuclear-radiation protection technology. The production method comprises the following steps: mixing natural glue, an accelerator, an oxidant, stearic acid, an antiager, rosin, light calcium carbonate, sulphur with gasoline; and then heating at high temperature so that the mixture is fully dissolved. The process is simple and reasonable and is easy for production and manufacture, and the prepared glue is in liquid state, is easy to spray and is easy to volatilize in the high temperature sulfidation process of gasoline. The glue for the nuclear-radiation shielding lead garment easily forms glue slurry, can perform sulfidation with lead fiber at low temperature, has good physical-mechanical properties, is in favor of economical production and lead fiber fixing and is good for repeated dressing and using; and on the premise of not reducing radiation protection function, the material of the lead garment is saved, and the lead garment is convenient for dressing and has good durability, so that the radiating time of maintenance personnel on the site is reduced by 50%.
Description
Technical field
The present invention relates to examine radiation protection technology, use the material production technical field especially for what make plumbous clothing inner bag that radioprotective uses.
Background technology
Studies show that, the external radiation exposure line of Nuclear power plants is mainly gamma-rays, it is mainly from the fission product of nuclear reaction with by the pipeline of neutron activation and valve, because the appearance of activation corrosion product in the pipeline, cause the deposition of radioactive particulate in the pipeline, make control region a lot of upkeep operation site surrounding dosage higher, increased staff's external irradiation dose, general employing shielding is removed.Therefore, on shielding material is selected, make every effort to highly effective and safe, low cost and save the space, select steel, lead, normal concrete and loaded concrete etc. usually.The intensity of steel is better, but price is higher; Concrete more cheap than heavy metal, but density is little, and shielding thickness is big; Plumbous advantage be density height, fusing point low, anti-corrosion, to gamma-rays good adsorption is arranged and be difficult for by through characteristic, be easy to cast and relative shielding thickness less, so lead is the shielding material of first-selection.
At present, China is at the Nuclear power plants of operation, the shielding goods (plumbous clothing or lead shield) that control region biological shielding system adopts mainly are: " the no gap solid metal block shape stereotype " of roll forming, this metal stereotype exist that protective value is low, conformal performance can be poor, the generation waste material is many, resource utilization is not high; The product heaviness, it is big to cause shielding operation labor intensity, and staff's exposure time is long, dosage is big, easily causes thermal insulation layer distortion, tenesmus, and the control region roentgen dose X increases, and safety coefficient is low, and potential risk is big; Be not suitable for special-shaped equipment such as pipeline, valve and personnel's shielding; And be difficult for decontamination, drawback such as work-ing life is short.Therefore, stereotype shielding goods are difficult to compatibility, sustainable development of incompatibility nuclear industry and the needs that people-oriented on shield effectiveness and structure function.
Studies show that anti-nuclear radiation biological shielding goods also must possess good physical and mechanical property (obdurability, thermostability etc.) except that will having higher shield effectiveness.It is reported that current, the material and the goods that are used for anti-nuclear radiation biological shielding mainly contain following four classes.One class is based on general industry lead, the no gap metal block shape stereotype of roll extrusion or casting, lead brick, sheet lead concrete etc.; Second class is based on lead powder, and rubber, polyethylene foam etc. are as mixed flexible article and coating, the tackiness agent etc. that are composited of base-material; The 3rd class be with no gap metal block shape sheet lead as heart, ectonexine coats crosslinked foaming material and the continuous synthetic fibre material product of synthetic rubber; The 4th class is to make light-weight high-strength materials such as cenosphere with heavy metals such as lead.Facts have proved that although stereotype, the anti-nuclear radiation effect of sheet lead goods are preferable, usage quantity is big when building shielding harness, it is big to build difficulty, inefficiency, and it is many to produce waste material, and potential risk is big; And stereotype goods conformal performance is poor, can not bend, and is not suitable for the shielding of special-shaped equipment such as pipeline, valve, and careless manipulation easily drops and hurts sb.'s feelings or damage equipment.And mixed goods, coating and the tackiness agent that is composited of lead powder and rubber, polyethylene foam-material, though have certain flexibility, but because the lead powder particle easily gathers, be difficult in base-material evenly mixed, so shielding properties is inhomogeneous, and protective value is low, rubber and polyethylene etc. are easily aging, influences shield effectiveness, brings by radiating danger to the staff.The cenosphere light-weight high-strength material that heavy metals such as lead are made, though anti-nuclear radiation performance is excellent, cost height, cost are big, generally are used for the anti-nuclear radiation of nuclear rocket engine and leak.
The contriver if can substitute thick and heavy stereotype, sheet lead with galvanized wire after further research, makes the sandwich layer of chip shielding goods, then can overcome the defective of above prior art.
Summary of the invention
The object of the invention is to propose the plumbous clothing glue of a kind of nuclear radiation shield of being convenient to wear.
Mainly form by natural gum, promotor, zinc oxide, stearic acid, anti-aging agent, rosin, light calcium carbonate and sulphur.
The mass ratio of natural gum of the present invention, promotor, zinc oxide, stearic acid, anti-aging agent, rosin, light calcium carbonate and sulphur is 1000 ︰, 10～12 ︰, 50 ︰, 7～9 ︰, 5 ︰, 20 ︰, 200 ︰ 20～22.
The plumbous clothing of nuclear radiation shield of the present invention easily forms rubber cement with glue, can form sulfuration at low temperatures with lead fiber silk, has good physical-mechanical properties, also be beneficial to save and produce, be beneficial to lead fiber silk and fix, be beneficial to dress repeatedly and use, under the prerequisite that does not reduce radiation proof function, make saving, conveniently wear with material of plumbous clothing, wearing quality is good, and the maintenance personnel is subjected at the scene according to time decreased 50 ﹪.
Another object of the present invention is to propose the production method of the plumbous clothing of nuclear radiation shield:
After natural gum, promotor, oxygenant, hard ester acid, anti-aging agent, rosin, light calcium carbonate, sulphur and gasoline mixing, extremely dissolve fully through heat.
Technology of the present invention is simple, reasonable, is easy to manufacture, and the glue of making is liquid, is easy to spraying, is easy to volatilization in the high temperature vulcanized process of gasoline.
