Abstract
This invention relates to one environment friendly anti-radiation compound board, which comprises the following materials: polychloroethylene, polypropylene, polyethylene, polyphenylacetylene, each kind of plastic resin adhesive agent and barium sulfate, barite powder, wherein, it is added with proper silver, copper, iron, aluminum powder and its oxidation and metal salt.
Description
Technical field the present invention relates to a kind of radiation proof material, particularly a kind of environment-friendly type radiation protection composite board.Be applicable to that hospital, factory, scientific research institution etc. have the workplace of x, γ, β neutron and radionuclide source to carry out radiation protection.
The existing radiation protection material of background technology mainly adopts the stereotype goods, uses the said goods, has following shortcoming: not environmental protection, and harmful, environment there is pollution, because of lead and very easily oxidation in air of leadwork, generate Pb
2O
3Or Pb
3O
4, can be free in the air simultaneously, increase lead content in the air, cause contact poisoning or breathing to be poisoned, produce a series of toxicity symptoms, surrounding environment also there is bigger pollution; Cost height, lead are heavy metals, and the domestic and international market price raises year after year in recent years, and the stereotype price has reached 1.2 ten thousand yuan/ton, use stereotype radiation proof cost higher; Protection effect is undesirable: stereotype density is higher, though radiation is had stronger protective capacities, easily produces Secondary radiation and scattered ray, staff's health is damaged, and relatively poor to the neutron protective capacities; Difficulty of construction is big, and is softer because of plumbous quality, when using stereotype and the radiation proof of stereotype goods, all need use other propping material, increased difficulty of construction like this, increased construction cost.
Summary of the invention the object of the present invention is to provide a kind of environmental protection, economy, novel radiation proof material easy to use, particularly a kind of environment-friendly type radiation protection composite board.
The technical scheme that solves the technology of the present invention problem is: adopt Polyvinylchloride or polypropylene, tygon, plastics such as polystyrene, plastic resin and corresponding adjuvant, inserts uses barium sulphate, barite powder and other barium salt, increase silver in right amount, copper, iron, calcium, aluminium, metal powder or their metal oxides such as tungsten, metal salt powder, make a kind of anti-x by a kind of production technology, γ, the compound substance of ray such as β and neutron, in plastics, fill above-mentioned barium sulphate, ground barium sulfate and other barium salt and metal, metal oxide and slaine, thus ray is protected preferably.The composition of raw materials weight portion is 1 part of plastics such as Polyvinylchloride or polypropylene, tygon, polystyrene or resin and a corresponding adjuvant, barium sulphate or other barium salt, ground barium sulfate pellet 1-10 part, other metal, metal oxide or slaine 0.01-1 part.
The present invention compares with existing stereotype and leadwork material, has the following advantages:
One, environmental protection: not leaded because of this material, it is mainly formed is to be made of the stable material of some physicochemical properties, does not therefore have the poisonous and harmful substance volatilization and leaks, simultaneously, the recyclable regeneration of this material can not constitute pollution to environment yet, and is particularly harmless to staff in this environment.
Two, economy: this material is mainly by PVC or other plastics of cheapness, barium sulphate, barite material and a small amount of other metal, metal oxide and metal salt material are formed, its cost of products is lower than stereotype, and in use stronger physical strength and stable physicochemical property are arranged because of this product, do not need to use propping material, use cost is lower.
Three, radiation proof is effective: multiple metallic elements such as argentiferous, copper, iron, aluminium, tungsten in the material of the present invention; constituted the composite protective performance; it can not only penetrate by the block radiation line; but and ABSORPTION AND SCATTERING line; like this; greatly reduce the Secondary radiation in the machine room, can effectively protect the staff to avoid the scattered ray injury.
Four, easy construction: because of this product strength is big, can saw, glue, nail, subsides and assembly unit, it is very convenient to construct, and detachably installs when machine room is reconstructed, and repeatedly uses.
Appended drawings is that the present invention makes flow process for two kinds: one: batching, mixing, pulverizing, banburying, refining glue, compressing tablet, lamination, moulding, finished product; Its two: batching, mixing, pulverizing, banburying, refining glue, extruding, finished product.
Embodiment the present invention realizes by following manner: with PVC or other plastics, various plastic resins, corresponding adjuvant and blanc fixe or ground barium sulfate and argentiferous, copper, iron, aluminium, the powder of metals such as tungsten or raw materials such as oxide or slaine or barium salt, add 1 to 10 part of blanc fixe or ground barium sulfate by 1 part of PVC or other plastics or various resin, add appropriate amount of auxiliary materials and plastifier, stabilizing agent, components such as release agent are through batching, mix, pulverize, banburying, refining glue, compressing tablet, the mode of lamination or extrusion molding obtains the environment-friendly type radiation proof PVC composite plate or the composite panel of plastic material of big specification.Its finished product thickness is 3mm to 50mm, and finished width is 100cm to 122cm, and length is no more than 500cm.
Radiation protection effect detection: cut 10cm * 10cm respectively, thickness is the PVC radiation protection composite board of 5mm, 10mm, 15mm, 20mm, under the 500MA X-ray machine, shine, use plumbous ladder to compare, put in the rare earth magazine with " 5 * 7 " X film and to expose, the time is 1 second, measures its transmittance with the automatic film developer back of developing a film with instrument, carry out lead equivalent relatively, draw lead equivalent data such as following table:
Lead equivalent data such as following table:
| Sheet metal thickness | 80KV 50mmA | 100KV 50mmA | 120KV 50mmA | Remarks |
| 5(mm) | 0.5 | 0.52 | 0.56 | Detecting data all represents with the mmpb equivalent |
| 10(mm) | 1.1 | 1.13 | 1.18 | |
| 15(mm) | 1.7 | 1.75 | 1.8 | |
| 20(mm) | 2.4 | 2.48 | 2.56 |
Above data show that when protecting with this composite protective plate, the result shows that X line kilovolt is high more, and composite plate lead equivalent is corresponding increases for this, and its protection effect is also good more.
