Abstract
The invention provides a kind of x-ray protection sheet material, as inorganic bonding material, and make screener with inorganic salts such as massicot, vulcanized lead, barium sulphate, barium chloride and barium carbonates with high-alumina cement, magnesium oxide, magnesium chloride and sodium silicate etc.Earlier cementing agent is mixed in proportion with screener, a kind of semifluid dung of mixing one-tenth, molding moulding on template thereafter obtains protective plates through curing.This board quality is light, intensity is high, and is not yielding, and convenient formation also has the fire prevention antihunt action, and the X line is had good protective capacities, can widespread use on the x-ray protection device.
Description
The present invention is relevant with ray protection material, more specifically says so about the protective materials of X ray.
Along with the development of modern science, radiation has been widely applied to the every field of national economy as a kind of new technology.X ray is more and more general in the application aspect medical, for fear of the X line human body is brought harm, and the protection of doing the X line well is necessary.Traditional protective materials of X line is plumbous.Plumbous mechanical property is bad, and physical dimension is very unstable, and is yielding, sagging, not shockproof, so lead can not be constructed separately, the clamping materials for support must be arranged.Because plumbous ratio is great, use very inconveniently, and lead resource lacks the use cost height.
The object of the present invention is to provide that a kind of barrier propterty is good, in light weight, easy-formation, the low protective plates easy to use of cost.
Solution of the present invention is that the compound substance made with a kind of screener, cementing agent and reinforcing material is as protective plates.Here said cementing agent is a kind of inorganic binder, can certainly use the organic binder bond of unsaturated polyester resin and so on.Said screener is a kind of inorganic salts.The constituent of making this protective plates comprises (weight %): 55～70 inorganic salts screener, 25～40 inorganic binder and 3～4 reinforcing material.
Said in the present invention inorganic salts screener is that lead compound and barium salt are formed.Select for use leadization thing or barium salt to make screener separately and also can obtain protection effect, but preferred composition is still selected both potpourris for use, its preferred proportion is 1: 1.Here the lead compound of indication is to be selected from massicot and/or vulcanized lead, both can use wherein a kind of separately, also can be with both potpourris; Said barium salt then is a barium sulphate, one or more potpourris in barium chloride and the barium carbonate.
The inorganic binder that uses among the present invention is to comprise a kind of solid binder composition and a kind of liquid adhesive glue composition, and both ratios are 1: 1.Said solid binder composition is selected from high-alumina cement and magnesium oxide, and both can mix use, also can choose one of them independent use wantonly, but preferred ratio still is 1: 1 a potpourri.Said liquid adhesive glue composition is selected from a kind of magnesium chloride brine and liquid sodium silicate.Both equally also can select for use separately, but method for optimizing also is to use both potpourris, and both preferred proportions are 1: 1.The concentration of said magnesium chloride is 65～80%(weight %), the concentration of sodium silicate is 10～50%(weight %).
The used reinforcing material of the present invention then is selected from a kind of in flaxen fiber, porcelain fiber or the glass fibre.
The production method of x-ray protection sheet material of the present invention is: (a) drop into cementing agent and screener in proportion in stirring mixer, mix, continue to be stirred to semi-fluid condition with stirring machine, make the semifluid binding that contains screener; (b) molding moulding.First shop one deck semifluid dung on template is then spread one deck reinforcing material, is that 150～200 the even vibration air exhaust of bumper is to smooth surface with frequency.So alternately lay 3～5 layers and make mold base.(c) 25～35 ℃ of following static curing 48～72 hours.(d) the said protective plates of the present invention is so just made in the demoulding, shaping.The advantage of using this inorganic binder is not to be afraid of wet environment in process of production, and is low to the humidity requirement of former material, can omit raw material drying technology, and can reduce cost.
Further specify technological process of the present invention with a concrete instance more below.In stirring mixer, drop into 2.5 kilograms of high-alumina cements and 2.5 kilograms of magnesium oxide, add again after 16 kilograms in 4 kilograms in massicot, barium sulphate mixes, 2.5 kilograms of sodium silicate that add 40% concentration again, 2.5 kilograms in the magnesium chloride of 70% concentration, continue to mix to presenting semi-fluid condition, obtain 30 kilograms of semifluid dung.Then on template, spread the semifluid dung of 1-1.5 millimeters thick earlier, repave layer of glass, spread one deck dung again, when vibration air exhaust is to smooth surface thereafter, continue again alternately to spread 3～5 layers, consume about 1.2 kilograms of glass fibre.So make the mold base of about 8 millimeters thick of thickness, 25～35 ℃ of down static curing 48～72 hours, the demoulding, shaping obtain thickness and are 8 millimeters one square metre of protective shield.
For showing the protection effect of the present invention, done the mensuration of barrier propterty by Taishan Hospital to the X line.Method of testing is measured with instrumental method according to the argumentation that old professor jade worker writes " X line physics " book, represents the receptivity of material to the X line with lead equivalent.The meaning of lead equivalent is: with measured material the thickness of the lead of same absorbent ability is arranged.With F34-1 type Stabilipan is radiographic source, the dose rate that sees through with the measurement of NYL-III type roentgenomater.
Assay method: select tube voltage 100KVP, Measuring Time 10 seconds,, write down the dose rate that sees through of each standard lead flake of 0.2～2.5 millimeters thick with the integral absorbed dose of roentgenomater.Result such as table 1.
Table 1, standard lead flake dose rate is measured
| Lead flake thickness (millimeter) | 0.3 0.4 0.5 0.6 0.7 0.8 …… | ||||||
| Dose rate (human relations/minute) | 4.8 3.2 2.1 1.6 1.3 0.9 …… | ||||||
With dose rate (human relations/minute) is ordinate, and standard lead flake thickness (millimeter) is abscissa, draws out logarithmic curve chart (accompanying drawing 1).
With measuring different plates that the present invention makes the dose rate that sees through under the condition to the X line, check in the lead equivalent of sample by accompanying drawing 1, and with iron plate product in contrast, test result such as table 2.
Table 2 plate property of the present invention is measured
| Sample number | The present invention | Reference substance |
| 1 2 | ||
| Thickness (mm) dose rate (human relations/minute) lead equivalent (millimeter) proportion (g/cm 3) | 8 16 0.5 0.05 1.2 2.2 3.4 3.4 | 5 0.7 1.1 7.81 |
Test result shows that the proportion of sheet material of the present invention is lighter than reference substance, but more much better than iron to the shielding properties of X line, has reached requirement of shelter.
Advantage of the present invention is clearly, uses this sheet material to make protective materials, light weight, intensity height, and more stable than the physical dimension of lead, not yielding, convenient formation need not any gripping object, and has the fire prevention shockproof properties.Cheap, durable in use, use light, can widespread use on the x-ray protection device.
Further specify the present invention with several embodiment more below, be not confined to this several example formulations scopes certainly.
