Abstract
The invention discloses a protective material and a method for eliminating radiation of a building material. The method comprises the following steps of: mixing 60-95% of building raw material with 5-40% of protective material in percent by weight; and preparing an anti-radiation building material according to the traditional process used for preparing the required building material, wherein the protective material is prepared by mixing the following materials in percent by weight: 5-80% of barium sulphate, 4-20% of silicon dioxide and 10-90% of thin and thick aggregate composed of magnetic iron ore, brown iron ore or/and barite. In the invention, high-density thin and thick aggregate is adopted, thus Gamma ray can be shielded; the silicon dioxide can effectively capture neutron current and does not form a secondary Gamma ray, shielding effect to neutron current Gamma ray is better, the adopted barium sulphate is non-toxic and tasteless, has no toxic or side effect to human body and has stronger shielding effect to X ray.
Description
Technical field
The present invention relates to a kind of protective materials, especially relate to a kind of protective materials for building that can protect α, β, γ, X ray and neutron current radiation, and a kind of method of using this protective materials to eliminate the building materials radiation.
Background technology
The material that uses in buildings is referred to as building materials.The wide range that novel building materials comprises.Building materials can be divided into structured material, ornament materials and some proprietary material.Structured material comprises timber, bamboo wood, stone material, cement, concrete, metal, brick and tile, pottery, glass, engineering plastics, compound substance etc.; Ornament materials comprises various coating, paint, coating, veneer, ceramic tile of all kinds, has the glass of special-effect etc.; Proprietary material refers to be used for waterproof, protection against the tide, anticorrosion, fire prevention, fire-retardant, sound insulation, heat insulation, insulation, sealing etc.
Even in some days hot building materialss, such as granite, radioelement such as uranium-bearing, thorium, the radiation of generation is unfavorable for health.For preventing the injury of ray, exist the building materials of radiation that protection body must be set to some to human body.What protection body generally will prevent is α, β, γ, X ray and neutron current.Because α, β ray penetration capacity are low, easily be absorbed, even the protective materials of very little thickness also can block them fully, so surfacecti proteon material itself just can protect.In design, the most important thing is to consider shielding to gamma-rays and neutron ray.Therefore, protection question mainly is summed up as the protection to gamma-rays and neutron ray.And the gamma-rays penetration capacity is strong, and during usually by the high density building materials, its energy can be weakened, and when reaching certain density and thickness, can be absorbed fully.Neutron ray is made up of the particulate of charged nuclear not, has the penetration capacity of height, wherein can be divided into quick middling speed and neutron at a slow speed, because their protective mechanism is different, so only consider that for the protection of neutron ray the density of material greatly also misses one's aim.
At present, composite protective material, stereotype, protective coating etc. are adopted in X ray, the auxilliary protection of penetrating of gamma-rays mostly.Though the stereotype protection effect is good, and is poisonous, and costs an arm and a leg.Chinese patent ZL90106378.9 is that the lead ore powder cement of employing brown iron oxide, ground barium sulfate, silicon dioxide, leaded grade is the packing material that radiation proof material is made.Other has the covil construction of x radiation x or anti-x radiation x occasion generally can't use.
Summary of the invention
The present invention propose a kind of can α, β, the protective materials of γ, X ray and neutron current radiation, and a kind of method of using this protective materials to eliminate the building materials radiation, solving present building materials needs to adopt protective shield and the not good technical matters of protection effect to gamma-rays, X ray and neutron current protection.
The present invention adopts following technical scheme to realize: a kind of protective materials is mixed by following substances in percentage by weight: barium sulphate 5-80%; Silicon dioxide 4-20%; By magnetic iron ore, limonite ore or/and the thickness that barite is formed is gathered materials 10-90%.
Wherein, the thickness grain size of gathering materials is the 150-200 order.
The present invention also discloses a kind of method of eliminating the building materials radiation, and it comprises step:
Building material with 60-95% mixes with the protective materials of 5-40% by weight percentage;
Employing adds water stirring, pressure forming or baking combination in any technology and makes radiation-resistant building materials;
Wherein, protective materials is mixed by following substances in percentage by weight: barium sulphate 5-80%; Silicon dioxide 4-20%; By magnetic iron ore, limonite ore or/and the thickness that barite is formed is gathered materials 10-90%.
Wherein, the protective materials by 90% building material and 10% mixes by weight percentage, and wherein, building material is barite, unsaturated polyester resin, drying promoter.Each component is pressed column weight amount percentage mix: barite 85%; Unsaturated polyester resin 4.8%; Drying promoter 0.2%; Barium sulphate 5%; Silicon dioxide 2%; Thickness gathers materials 3%.
Wherein, the protective materials by 80% building material and 20% mixes by weight percentage, and wherein, building material is gesso or concrete.Each component is pressed column weight amount percentage mix: building material 80%; Barium sulphate 10%; Silicon dioxide 3%; Thickness gathers materials 7%.
Compared with prior art, the present invention has following beneficial effect:
The present invention adopts the high thickness of density to gather materials can shield gamma-rays, silicon dioxide can effectively be caught neutron current and do not formed the secondary gamma-rays, better to neutron current gamma ray shielding effect, used barium sulphate is nontoxic, tasteless, without any side effects to human body, X ray is had stronger shielding action.
