Description
Technical field
The present invention relates to radioactive contamination Engineering Control and decontamination material field is removed, there is core spoke more particularly, to one kind
Penetrate the radioactive contamination control and removing decontamination material of function of shielding.
Background technique
Well known, continually developing and applying with nuclear power source is also improved day by day about the applicable technology of core, although core
The development and utilization of energy brings huge economic benefit and social benefit to the mankind, but is influenced by the prior art, in nuclear facilities, core
In the link of fuel processing and application, such as in the places such as exploitation, transport, processing, storage and nuclear waste disposal, all different journeys
Degree generates a large amount of radioactive contamination, in addition, nuclear power plant accident, nuclear radiation attack of terrorism etc. can all generate largely
Radioactive contamination brings threat to the living environment of the mankind；Currently, Engineering Control and removing material master for radioactive contamination
Have: dry remover, decontaminant, chemical foam/gel detergents and peelable film coverture etc., wherein due to peelable film
Coverture radioactive contamination can be pressed into building machinery sprinkling or by way of brushing and equipment surface forms covering
Layer, and radioactive pollution is removed by way of removing cover film after drying and forming-film, therefore, peelable film coverture just becomes
Material is removed in a kind of more common radioactive contamination；However, only radioactivity is stained with when using such material decontamination
Dye is wrapped in coverture, dry in cover film and before removing, and the nuclear radiation harm for being infected with place always exists, this will be
The exposure duration that operating personnel is greatly increased when extensive radioactive contamination disposition, to subsequent disposing task and operating personnel
It adversely affects, has been greatly reduced the timeliness of radioactive contamination emergency disposal, i.e., existing stripping film coverture is not because having
Standby radiation shielding capability can not be advantageously applied to extensive radioactive contamination Engineering Control and remove operation.
Summary of the invention
In order to overcome the shortcomings in the background art, the object of the present invention is to provide a kind of putting with radiation shielding capability
Penetrating property contamination control and removing material.
For achieving the above object, the present invention adopts the following technical scheme:
A kind of radioactive contamination control with radiation shielding capability presses matter by following component with removing material, the material
Measure number composition: 100 parts of acrylate polymer, 20~35 number of lead oxide powder, 1~3 part of polyvinyl alcohol.
Further, the material is made of following component by mass parts: 100 parts of acrylate polymer, lead oxide powder
20 parts, 1 part of polyvinyl alcohol of end.
Further, the material is made of following component by mass fraction: acrylate polymer 100, lead oxide powder
Last 30, polyvinyl alcohol 2；The material is made after 0.5h is mixed in normal temperature environment in said components.
Further, the material is made of following component by mass fraction: 100 parts of acrylate polymer, lead oxide
35 parts of powder, 3 parts of polyvinyl alcohol.
Further, the acrylate polymer is by butyl acrylate, ethyl methacrylate, acrylonitrile, acrylic acid
It is formed by the mass ratio of 45:45:8:2 through free radical polymerization.
Further, the lead oxide powder can be substituted by ceruse or lead tungstate.
Further, the material is according to 6kg/m2Dosage spilt by corresponding spray appliance in air or earth's surface cloth.
Due to the adoption of the technical scheme as described above, the invention has the following beneficial effects:
Radioactive contamination control of the present invention with radiation shielding capability can be in normal temperature environment with removing material
Lower simple, rapid synthesis, and it is capable of the radioactive contamination of adsorption and sedimentation air and earth's surface after spraying, and pollutant is suppressed
It is isolated in ground and forms continuous cover film, so that radioactive contamination be prevented to have the radiation hazradial bundle of the area people and equipment
Effect solves existing pollution cleanup material because of operation exposure duration length, membrane body removal caused by not having radiation shielding capability
The problem that preceding nuclear radiation always exists；Be very suitable to speedily carry out rescue work to Nuclear Accident Emergency the radioactivity of the rescue passage area that must pass through
Contamination carries out quickly disposition operation, and the dose of radiation of operating personnel and equipment can be greatly reduced, to effectively enhance disposal area
Passability and emergency management and rescue timeliness.
Specific embodiment
The synergistic effect between the effect and each component of each component in the present invention is explained as follows below:
1, acrylate polymer, as basic film forming matter, i.e., by acrylate polymer be sprayed on ground or
In equipment, the coating of membrane structure is formed after to be dried, radioactive contamination is wrapped in coating；
2, lead oxide powder is used for radiation shield, for chemically reacting with the carboxyl in acrylate polymer
Lead element is introduced, so that material of the present invention be made to have radiation shielding capability；
3, polyvinyl alcohol is dispersing agent, can be effectively reduced group of the lead oxide powder in acrylate polymer emulsion
It is poly-, to play the dispersing uniformity for increasing lead oxide powder, be conducive to the introducing of lead oxide.
Specific implementation of the invention is illustrated below by way of three embodiments:
