Abstract
The invention provides a novel anti-radiation material and a CT (computed tomography) chassis made with the novel anti-radiation material. The anti-radiation material comprises a resin material, a fiber material and a tungsten-molybdenum material. Due to combination of the resin material and the fiber material, high strength of the material can be ensured. Moreover, since the tungsten-molybdenum material of a high atomic number is used, the function of absorbing radiation can be achieved, and the impact on the human body and the environment is very low.
Description
Technical field
The present invention relates to a kind of radiation proof material, also relate to a kind of CT casing that utilizes this kind radiation proof material to process.
Background technology
At present, CT has become important medical imaging equipment.Increasing people accept CT scan in medical diagnosis.But X ray can increase and receives radiation person and suffer from the probability of cancer, especially bigger for women and children's risk.Therefore how to reduce radiation dose is perplexing industry all the time.
Up to now, most CT shells are processed by glass fiber reinforced plastics, but this shells does not have the radiation shield function, thereby cause requiring very high to the radiation proof of CT Room.
In addition, adopt lead material as radiation proof material in the prior art usually, but, human health and environment have all been brought adverse influence because lead material toxicity is high.
Therefore, the radiation proof material that needs a kind of environment-protecting asepsis and have the good material performance.
Summary of the invention
In view of this, the present invention proposes a kind of radiation proof material.It can prevent radiation effectively, and is very limited to the influence of human body and environment simultaneously.
The object of the invention can realize that this radiation proof material comprises resin material through following radiation proof material, fibrous material and tungsten and molybdenum material.
Preferably, fibrous material of the present invention can be spun glass or carbon fibre.Spun glass or carbon fibre can strengthen the intensity of this radiation proof material greatly.
In another selectivity scheme, the tungsten and molybdenum material in this radiation proof material is tungsten powder or molybdenum powder, selects for use tungsten powder or molybdenum powder can reduce the cost of selecting for use tungsten plate or molybdenum plate to be produced greatly, plays identical substantially radiation proof effect simultaneously.
Further preferably, among the present invention, the diameter of tungsten powder or molybdenum powder is less than 15 microns, and the tungsten powder of above-mentioned size or molybdenum powder can be mixed with fibrous material with resin material more equably mutually, thereby realize better radiation proof effect.
Equally preferably, said resin can be a kind of in epoxy resin, vinyl acetate or the thermoplastic polyester, selects for use above-mentioned resin can play the effect of reinforcing material.
Optionally, said radiation proof material may further include aluminium oxide, thereby this radiation proof material can possess fire-proof function simultaneously.
Preferably, said radiation proof material comprises the skin of being processed by resin material and fibrous material, and be clipped between the said skin, by the middle layer that resin material and tungsten and molybdenum material are processed, sandwich construction is the intensity of reinforcing material further.
Further preferably, the said outer field outside is coated with the gel coat coating, is used to protect coated inside and beautifies outward appearance.
The invention allows for a kind of CT casing that utilizes above-mentioned radiation proof material to process.Preferably, this CT casing can further be added with alumina material.
Can find out that from such scheme utilizing the radiation shield shell of the CT machine that radiation proof material of the present invention processes is a kind of effective means that reduces unnecessary radiation, also can not influence the quality of imaging simultaneously.This CT casing also has other function, promptly shields from main radiation component, such as banj, collimating apparatus and detector (detector), and it prevents that patient from accepting excess radiation, and the shielding properties of enhanced system.Simultaneously, the processing with low cost and easy of this radiation proof shell meets the RoHS standard.

Embodiment
For making the object of the invention, technical scheme and advantage clearer, below lift embodiment to further explain of the present invention.Below explanation will be explained the present invention as an example with the shell of CT machine, but should be noted in the discussion above that this material is not limited only to make CT machine shell.Simultaneously, alleged " tungsten and molybdenum material " is not limited in " tungsten " perhaps " molybdenum ", and is meant this tungsten series elements material.
As shown in fig. 1, in one embodiment, radiation proof material of the present invention can be a sandwich construction, comprises middle layer 1 and outer 2.Middle layer 1 can be the tungsten and molybdenum material plate, also can be formed by resin and tungsten and molybdenum material powder mixes.Adopt the potpourri of resin material and tungsten and molybdenum material powder can overcome the relatively poor restriction of simple tungsten and molybdenum material plate rigidity.Select for use the reason of tungsten and molybdenum material to be that tungsten belongs to high atomicity element, has superior X-ray absorptive character.Simultaneously, tungsten and molybdenum material toxicity is little, and is also little to the influence of environment.
As the resin of base material, can select epoxy resin, vinyl acetate or thermoplastic polyester for use.
In a preferred embodiment of the invention, the diameter of tungsten and molybdenum material powder is less than 15 microns, and the tungsten and molybdenum material powder can be blended in other material more equably like this, realizes better radiation proof effect.
Simultaneously, according to the difference that in the practical application strength of materials is required, can select different fibrous materials as skin 2, to reach the purpose of reinforcing material.Preferably, can select glass fiber material, its Costco Wholesale is cheap and intensity is very high.Further preferably, if higher, then can select carbon fibre material to requirement of strength.
In another preferred embodiment of the present invention, can also optionally add alumina material, it can realize the fire performance of radiation proof material.
In addition; Can also want mixture layer 7 surface applied gel coats (gel coating resin) 6; Gel coating resin is a kind of special resins in the unsaturated polyester resin; Its role is to improve spun glass, strengthen the presentation quality of unsaturated polyester resin base glass fiber reinforced plastics product and the material of protection structural sheet does not receive the external environment erosion medium resistance, promptly to the incrustation of this composite product with to the protection of structural sheet.
Below will combine Fig. 2 that the processing technology of this sandwich construction radiation proof material is described.
A. at first on open mold 3, apply the skin (appearance) that gel coating resin is processed;
B. resin and hardening agent are coated on the gel coating resin;
C. at above-mentioned surface tiling fibrous material layer 5, it is real with lamination to solidify roller 4 with wetting this part and utilization, squeezes with the bubble with interlayer;
