Abstract
The present invention relates to radiation protecting coating material and a preparation method thereof, which is used for shielding protection of buildings of X rays and gamma rays in working places. The radiation protecting coating material is composed of radiation protecting base material made of 40% to 70% of barium salt, 5% to 20% of iron oxide red, 10% to 20% of calcium carbonate and 10% to 20% of quartz powder, an adhesive agent made of cement, an organic polyester adhesive agent, and a small quantity of additives, wherein 71% to 85% of the radiation protecting base material, 13% to 25% of the cement, and an early strength water reducing agent with the mesh over 300 and with the proportion by weight of 0.25% to 4% of the cement are prepared into dry powder material through mixing and uniform stirring and are mixed into a semi-fluid state after added with water and the organic polyester adhesive agent; the radiation protecting coating material is used for shielding protection of X rays and gamma rays of the buildings in the working places by directly painted on a building shielding body. The radiation protecting coating material produced by the method has the advantages of low cost, innocuity, high safety, easy construction and good protective property; when the thickness of the coating is 15MM, the lead equivalent is 1.68 mmpb.
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, additive and the water be made up of cement and organic polyester adhesive are formed;
