Abstract
The invention discloses radiation-proof putty powder and a preparation method and application thereof. The radiation-proof putty powder is characterized by consisting of the following components in part by weight: 65 to 75 parts of quartz powder, 5 to 15 parts of barite powder and 15 to 25 parts of limestone powder. A formula of the radiation-proof putty powder material is obtained; and after the putty powder is coated on the surface of a wall or a brick, the putty powder can effectively shield the radioactivity of the wall or the brick. Tested by the applicant, the combination of the barite powder (barium sulfate), the quartz powder (silicon dioxide) and the limestone powder can effectively shield the radiation of radioactive substances and achieve the using effect of the putty powder at the same time. Therefore, the invention provides a new thought for the application field of barite, and improves the use value of the barite.
Description
Technical field
The present invention relates to a kind of radioprotective putty powder, belong to the putty powder preparing technical field.
Background technology
It is Powdered that putty powder is, and is before the lacquer class is constructed, construction surface to be carried out pretreated a kind of surperficial packing material.In the prior art, the raw material of putty powder mainly is a calcareous material, adds a spot of tamanori, mainly is when application, construction surface to be handled, and makes construction surface smooth, so that carry out the coating operation.
Summary of the invention
The objective of the invention is to, a kind of radioprotective putty powder is provided.Can effectively stop the radiation of radioactive substance.
Technical scheme of the present invention.The radioprotective putty powder by weight, is made up of 65-75 part konilite, 5-15 part ground barium sulfate and 15-25 part limestone powder.
Above-mentioned radioprotective putty powder by weight, is made up of 68-72 part konilite, 7-12 part ground barium sulfate and 18-22 part limestone powder.
Above-mentioned radioprotective putty powder by weight, is made up of 70 parts of konilites, 10 parts of ground barium sulfates and 20 parts of limestone powders.
The preparation method of radioprotective putty powder stirs after konilite, ground barium sulfate and the limestone powder mixing with above-mentioned weight proportion, obtains finished product.
Above-mentioned preparation method, konilite, ground barium sulfate and limestone powder all are crushed to the 325-400 order.
The application of ground barium sulfate in preparation radioprotective putty powder.
The present invention has obtained a kind of radiation-resistant putty powder material mixture ratio that is used for, adopt putty powder of the present invention to be coated in body of wall, brick surface after, can effectively shield its radioactivity.As the flyash brick (radioactivity internal radiation index is 1.1-1.6 Becquerel/kilogram) that adopts radioactivity to exceed standard; After applying the putty powder of the present invention of one deck 0.5 millimeter; Detect its internal radiation index decreased to 0.3-0.5 Becquerel/kilogram, reached national internal radiation index (less than 1 Becquerel/kilogram) standard.The applicant at ground barium sulfate (permanent white) but the enterprising row in radiation-safe basis further study, develop another purposes of barite deposit, promptly be used for the preparation of radioprotective putty powder coating.China's tiff aboundresources, 26 provinces in the whole nation, all there is distribution in city autonomous region; Mainly concentrate on south, Guizhou Province accounts for national total reserves 1/3rd, and Hunan, Guangxi occupy second, third position, the whole nation respectively; China's tiff not only reserves is big, and of high grade, BaSO4>92.8%.And in the prior art; Tiff is mainly used in industrial sectors such as oil, chemical industry, paint, filler, is used in the radioprotective field, also just simply with tiff as filler; Put into concrete or pavior, do not have the relevant report of tiff as the putty powder coating.Through applicant test, ground barium sulfate (permanent white) is added that konilite (silicon-dioxide) and limestone powder (lime carbonate) combine, can effectively shield the radiation of radioactive substance, the while can also reach the result of use of putty powder.Therefore, the present invention provides a kind of new thinking for bar Application Areas, has improved the use value of barite deposit.
Embodiment
Embodiments of the invention 1.The radioprotective putty powder by weight, by stirring after 65-75 part konilite, 5-15 part ground barium sulfate and the mixing of 15-25 part limestone powder, obtains the radioprotective putty powder.Konilite, ground barium sulfate and limestone powder all are crushed to the 325-400 order.
Embodiments of the invention 2.The radioprotective putty powder by weight, is made up of 68-72 part konilite, 7-12 part ground barium sulfate and 18-22 part limestone powder, and above-mentioned materials all is crushed to 350 orders, obtains the radioprotective putty powder after stirring.Wherein, Konilite is that dioxide-containing silica grinds the silica powder that obtains in the natural powdery quartz ore deposit more than 98%; Ground barium sulfate is that barium sulfate content grinds the ground barium sulfate that obtains at the barite deposit more than 90%, and limestone powder is that calcium carbonate content grinds the limestone powder that obtains at the limestone mine more than 90%.
Embodiments of the invention 3.The radioprotective putty powder by weight, is made up of 70 parts of konilites, 10 parts of ground barium sulfates and 20 parts of limestone powders.Wherein, the dioxide-containing silica of konilite is more than 99%, and the barium sulfate content of ground barium sulfate is more than 92%, and the calcium carbonate content of limestone powder is more than 92%.Konilite, ground barium sulfate and limestone powder all are crushed to 380 orders.
