Abstract
A method for preparing radiation proof coating material used for shielding protection against x and y ray includes preparing radiation proof base material made of barium salt, iron oxide red, calcium carbonate, and ground quartz, mixing propared base material with cement, binding admixture of organic polyester and small amount of additives. Its dried powder is prepared by mixing the base material, cement and early strong water-reducing agent and its semi-fluid final product can be obtained by mixing dried powder with water and organic polyester binding admiture.
Description
Technical field: the present invention relates to a kind of X of stopping, gamma-ray radiation shielding coating and preparation method thereof, belong to antiradiation material and preparation method's technical field.
Background technology: along with radioactive rays at field widespread use, particularly X, gamma-rays such as health care, defence and military, scientific research, industry, agriculturals, become people to use maximum ionizing rayss; Radiotechnology has been brought huge economic benefit to society, and but then, because its energy height, penetration power is strong, and human physiological functions is had in various degree detrimental effect; Symptoms such as skin burn, trichomadesis, lens opacity of eye, leukopenia, sexual hypofunction can appear in the people as long-term contact x-ray bombardment; Weight person causes genetic flaw and brings out cancer; For stopping X, gamma-ray radiation, early stage people adopt the stereotype protection, and well-known, plumbous matter is soft and poisonous, long easy creep of time, and construction of prevention work program complexity costs an arm and a leg; X, gamma-rays all have stronger penetration power, and it can pass general thickness building masonry wall, ceiling, though yield of radiation weakens to some extent, assist but still HUMAN HEALTH is constituted certain prestige, block ray for making body of wall, usually with its thickening, this method is not only wasted material of construction, also useful spaces that accounted for more; X, gamma-rays are adopted stereotype, barium cement, composite protective plate such as Japanese Patent Publication 64-6433 more both at home and abroad at present, CN92 1 06491.8, CN 86 1 00457.4, protective coating such as CN 88 1 05952.8, filling anti-radiation material such as CN 90 1 06378.9 carry out radio-protective; Barium cement and protection body adhesiveproperties are poor, easily chap, come off; Composite protective board production technology complexity, the seam thread cast-off also is difficult for handling between plate; Existing radiation shielding coating, filling anti-radiation material all contain hazardous and noxious substances lead and compound, volatile organic compounds and the free formaldehyde of national standard restriction; The filling anti-radiation material is to be filled in the middle of the body of wall in addition, has destroyed the body of wall complete structure, has building safety hidden danger, crack or hole occur as charges in construction and use, can't be it is found that to have potential hazard.
Summary of the invention: The present invention be directed to the deficiencies in the prior art, seek that production technique is simple, easy construction, the occupation of land space is little, raw material sources abundant, cheap and not leaded and hazardous and noxious substances such as compound, volatility toxic pollutant, prevent X, the effective radiation shielding coating of gamma-rays, and a kind of radiation shielding coating and preparation method thereof is provided.The radioprotective base-material that radiation shielding coating is made up of barium salt, silica powder, red iron oxide and lime carbonate, caking agent, compound and the water be made up of cement and organic polyester tackiness agent are formed;

It is stand-by that its mixing and stirring is mixed with the radioprotective base-material;
The preparation method of radiation shielding coating: 0.25%～4% the early strength water-reducing agent that radioprotective base-material, 13%～25% cement, the granularity of getting 71%～85% mixing and stirring is that 300 orders are above, weight ratio is cement weight, its mixing and stirring is made into dry powder material, get 1%～3% white glue with vinyl again, by white glue with vinyl: water=1: 5 is mixed into milk sap, pour in the dry powder material that mixes, adding water again stirs, be the moving state of semi-fluid, the suitable building plastering mortar of denseness is promptly made radiation shielding coating and can have been used.
The present invention is suitable for radiation working space shielding protection very much, as hospital's x ray room, CT Room, industrial x-ray crack detection room and radio isotope machine room etc.
The present invention has following beneficial effect, advantage and characteristics:
1, radiation shielding coating of the present invention has good shielding property, when its area density is 4.5kg/m
2The time, protective value reaches 1.68mmpb.
2, not leaded and compound in the radiation shielding coating component, poisonous and harmful tackiness agent, free formaldehyde etc. can not pollute the working space.Waste material can not cause the secondary pollution ecotope.
3, radiation shielding coating easy construction, good with the protection body adhesiveproperties, not chap, do not come off, no matter newly-built or original radiation working space all can adopt.
4, the radiation shielding coating raw material sources are abundant, and cheap, production technique is simple and reliable, and it is low to consume energy, and product performance are stable, transport easily and store.
