Abstract
The invention provides a quick dry type neutron-shielding lacquer putty and a method for preparing the same. The quick dry type neutron-shielding lacquer putty is used for filling a hole or an aperture of a neutron radiant point shielding structure in order to reduce the leakage of neutron radiation and improve the whole protective performance of a shielding system. The material is prepared by adopting a coagulant, a neutron moderator, a neutron absorber, a colorant, water and other compositions mixed together. The quick dry type neutron-shielding lacquer putty has good neutron-shielding performance, short drying time, simple structure, convenient construction, strong practicability and good economical benefit.
Description
Technical field
The present invention relates to a kind of anti-neutron size putty and preparation method thereof, be used for the shielding protection in all kinds of neutron radiations sources such as isotope neutron source, nuclear reactor, rumbatron.
Background technology
Isotope neutron source, nuclear reactor and accelerator can produce nuclear radiation in operational process, especially the neutron radiation penetrativity is very strong, and operator's health is caused huge threat.General now use iron, lead, polyethylene, paraffin or composite shielding material carry out shielding protection to these source of radiation, these materials are in the process of installing and using, the material junction can stay a little slit, and neutron radiation can be damaged operator by these places, slit, reduces the protection effect of bulk shielding structure greatly.Secondly pipeline and hole road are more around source of radiation, and the void shape irregular that forms on shielding construction adopts existing shielding material to be difficult to accomplish tight radio-protective.In order in construction process, these slits and cavity effectively to be shielded and to protect, adopt and prevent that neutron putty is filled up these slits and the cavity is the obvious and inexpensive method of effect.
Traditional aqueous putty is at normal temperatures because the water velocity of evaporation is slower, putty is longer time of drying, and necessary rapid drying after some particular application requires the putty construction to finish, with the security of assurance equipment and shielding construction, so be badly in need of a kind of rapid drying type neutron shield putty of exploitation on the market.
Summary of the invention
The object of the present invention is to provide a kind of anti-neutron size putty, be used for filling up of neutron emitter shielding system cavity and slit.
Above-mentioned purpose of the present invention reaches by the following technical programs:

A kind of preferred version is characterized in that: described peptizer is putty powder, cement or gypsum etc.
A kind of preferred version is characterized in that: described neutron moderator is a polyethylene.
A kind of preferred version is characterized in that: described neutron-absorbing material is szaibelyite, borax, boron powder, norbide, lithium fluoride, gadolinium sesquioxide.
A kind of preferred version is characterized in that: described tinting material is iron oxide black, carbon black.
The production technique of anti-neutron size putty is various solid powders to be mixed in proportion to make putty powder earlier, during construction putty powder and water is in harmonious proportion in proportion use, finishes construction in 1～2h.Water also has the effect of neutron moderator.
Beneficial effect:
Anti-neutron size putty disclosed by the invention, the neutron shield excellent performance, anti-neutron performance is better than the polythene material of stack pile, time of drying is at 3～4h, meet the construction needs, technology is simple, easy construction, can be widely used in the construction aspect of isotropic substance radioactive source, Nuclear power plants, nuclear reactor, accelerator shielding safeguards, have wide economic benefit and good social benefit.
