Description
Technical field
The present invention relates to shielding coating field, specifically a kind of Lead free coating and its preparation for shielding X-ray
Method.
Background technique
Since discovery X-ray in 1895, discovery naturally radioactive in 1896, discovery artificial radioactivities in 1934 and 1938
It was found that ionising radiation is followed in various industry, agricultural, medical and health organization, education, research institution and nuclear fuel since nuclear fission
It is widely used in ring facility and fast-developing.Especially it is indispensable to have become modern medicine for X ray image technology
Important component, X-ray provide indispensable application value for clinical diagnosis.It is well known that X-ray is to tissue
There is stronger penetrability, and to the tissue penetration of different densities difference.Therefore, black and white layer can be shown through X-ray
Secondary different tissue image, is shown by film or fluorescent screen, and doctor can diagnose the illness whereby or implement to perform the operation.X is penetrated
Line image technology has become the indispensable important component of modern medicine.However X-ray itself is to by according to doctor and patient
Body cause to damage.In order to protect the health of doctor and patient, the material for needing to have strong absorption with a kind of pair of X-ray
Protective articles is made into shield the irradiation of X-ray.Moreover, in recent years, the every basic research for surrounding ray applications and carrying out
The impetus with industrial technology exploitation is in the trend risen rapidly, this also requires the fixed occasions such as building instrument to have good ray
Shielding properties.
Current main radiation proof material has radiation protection lead glass, stereotype, protective door and various wardrobe for lead protective clothes etc., but on
It states that radiation protection material is not only toxic but also quality is hard, cannot attach and be set with curved-surface structure, complex appearance well
Standby instrument periphery carries out effective radiation protection, and scienology development is maked rapid progress, and in terms of modern science viewpoint, this material is not
It is able to satisfy the needs of social development.
Summary of the invention
The present invention in order to overcome the deficiencies of the prior art, uses tungsten powder and bismuth meal for packing material, and acrylic resin is matrix,
A kind of Lead free coating and preparation method thereof for shielding X-ray is prepared, material non-toxic had both been able to satisfy and there is stronger ray
Absorbability, and be able to achieve and be widely used easy for construction etc. require.
To achieve the above object, a kind of Lead free coating and preparation method thereof for shielding X-ray, including following matter are designed
Measure the raw material of percentage: raw material A, 0~85%wt of tungsten powder, 0~80%wt of bismuth meal, 15~20%wt of acrylic resin；Raw material B, alcohol
90~95%wt, 5~10%wt of silane coupling agent；Respectively account for total weight 50% of the raw material A and raw material B；
Its preparation flow includes the following steps: S1, is modified processing to tungsten powder, bismuth meal；Propylene is added in S2 in the mixing container
Tungsten powder, bismuth meal is added in acid resin while stirring；The anti-settling agent of coating quality 1% and 1% defoaming is added after stirring six hours in S3
Agent；S4, viscosity as needed are added dilution regulator and adjust stickiness.
Include the following steps: S11 in the step S1, a certain amount of alcohol is taken to be placed in water bath with thermostatic control equipment, silicon is added
Alkane coupling agent, is mixed；After being sufficiently mixed uniformly, tungsten powder, bismuth meal is added, and ensure that alcohol did not had tungsten powder, bismuth meal in S12；
S13, constant temperature stir two hours, to vaporized alcohol it is complete after, be put into baking oven ten hours, it is spare；Baking oven temperature in the step S13
100 DEG C of degree.
In the step S3, the mode of stirring uses magnetic agitation.
The present invention compared with the existing technology, uses tungsten powder and bismuth meal for packing material, and acrylic resin is matrix, is prepared for
Novel ray shielding coating；Not only it had been able to satisfy material non-toxic and there is stronger ray absorption capacity, but also be able to achieve to be widely used and apply
Work, which facilitates etc., to be required.
