Description

Radon-proof gas coiled material and preparation method and application thereof
Technical Field
The invention belongs to the technical field of radon gas-proof materials, and particularly relates to a radon gas-proof coiled material, and a preparation method and application thereof.
Background
Radon is colorless, odorless and tasteless inert gas, is the only natural radioactive gas in the nature, is the decay product of radium metal, has radioactivity, has half-life of only 3.8 days, mainly comes from room foundation soil, building materials, water supply, natural gas for heating and kitchen equipment and the like, and can permeate into general air or water bodies from soil and rocks. In many areas with special geology around the world, the stratum contains uranium ore (or radioactive seeds of uranium such as radium) and causes trace radon gas in the air, if the ventilation in the room is poor, the radon gas can be accumulated to the concentration which can generate poison, the radon gas cannot generate immediate poison when being inhaled, and the main influence of the radon gas on human health is lung cancer.
At present, protection against radon gas is mainly accomplished by using paint. CN105885618A discloses a radon-proof paint which is prepared from the following raw materials in parts by weight: 10-20 parts of titanium dioxide, 32-50 parts of water-based epoxy resin emulsion, 3-8 parts of water-based color paste, 5-12 parts of beeswax, 4-8 parts of paraffin, 1-3 parts of aluminum oxide, 5-8 parts of dimethyl carbonate, 12-22 parts of high-boiling-point solvent, 3-8 parts of organic silicon modified acrylic resin, 2-5 parts of oily flatting agent, 3-5 parts of silicon dispersing agent, 2-4 parts of defoaming agent and 25-35 parts of deionized water. The provided radon-gas-proof paint can form a compact physical paint film on a wall surface, the paint film has good radiation resistance, the paint film is kept from being damaged, and the radon gas in the wall body can be shielded for a long time from harming human bodies; so that the indoor radon gas concentration is lower than 60Bq/m for a long time and accords with the national regulation. CN101880504A discloses a water-based radon-gas-proof interior wall coating, which consists of A, B components, and a water-based radon-gas-proof interior wall coating which consists of A, B components, wherein the A component contains: 12-20 parts of water, 20-25 parts of pigment, 50-60 parts of water-based epoxy resin emulsion and 0-2 parts of water-based color paste, wherein the component B comprises: 20-30 parts of water-based curing agent, 50-60 parts of filler and 15-25 parts of water, and the coating formed by the components can form a compact physical paint film which has good radiation resistance and can shield the harm of radon gas in a wall body to human bodies for a long time. The coating is scrubbing-resistant and stain-resistant; by adding different color pastes and adjusting the consumption of raw materials, the coating with various colors can be obtained, and the decorative effects of highlight, mercerization, matte and the like can be obtained according to the requirements, thereby meeting the requirements of different interior decorations. CN104263037A discloses a water-based radon-gas-proof interior wall coating, which is composed of the following raw materials in parts by weight: 0.6-1 part of 5-hydroxy-2-adamantanone, 0.7-2 parts of hydroxy silicone oil, 2-4 parts of zinc borate, 801-2 parts of polysorbate, 0.7-1 part of calcium acetylacetonate, 2-4 parts of ethylene glycol ethyl ether acetate, 0.7-1 part of sodium carboxymethylcellulose, 0.4-1 part of cross-linking agent TAC, 3-5 parts of bamboo charcoal powder, 2-3 parts of polyisoprene, 10-14 parts of wollastonite powder, 70-100 parts of tetramethyl tetravinylcyclotetrasiloxane, 120-160 parts of butyl methacrylate, 130-200 parts of isooctyl acrylate, 500-600 parts of deionized water, 2-4 parts of sodium persulfate, op-103-4 parts and 4-5 parts of bonding auxiliary agent. However, the radon gas-preventing effect of the three methods is still to be improved because the paint film is loose and has air permeability, a real compact paint film cannot be formed, and the radon gas diffusion from the wall building material cannot be shielded.
Therefore, the development of the radon-proof coiled material with excellent radon-proof effect has important significance.

And (3) performance testing:
(1) radon gas permeability: testing was performed according to YBB00082003-2015 gas transmission capacity assay;
(2) water impermeability: the test was carried out according to GB/T328.10-2007 "bitumen and Polymer waterproofing roll".
The radon-shielding gas coiled materials obtained in examples 1 to 6 and comparative examples 1 to 3 were tested according to the above test method, and the test results are shown in table 2:
TABLE 2
Figure BDA0002814152140000111
As can be seen from the data in table 2:
the radon-preventing coiled material provided by the invention has an excellent radon-preventing effect and excellent water impermeability; specifically, the radon gas permeation amount of the radon gas-proof coiled material provided in embodiments 1 to 5 is 0.0029 to 0.0082cm3/m224 h.0.1 MPa; and the water is not permeable when the test pressure is 0.4MPa and the test time is 120 min; compared with the radon-proof coiled materials provided by the comparative examples 1-3, the radon gas permeation amount is reduced by 12-628%, and in the comparative example 3, because no reinforcing layer is arranged, the obtained radon-proof coiled material starts to permeate water when the test pressure is 0.4MPa and the test time is 120 min.
Comparing example 1, example 4 and example 5, it can be seen that the barrier effect of the sheet of radon gas obtained by adding either basf puritar 3-15 (example 5) or activated carbon (example 4) alone is inferior to the barrier effect of the sheet of radon gas obtained by adding both (example 1).
Comparing example 1 with example 6, it can also be found that the radon gas transmission amount of example 1 is lower, which indicates that it has better radon gas-proof effect, and it is proved that the radon gas-proof effect of the radon gas-proof coiled material can be further improved by using the aluminum foil composite polyester shielding film as the reinforcing layer.
The applicant states that the present invention is illustrated by the above examples to provide a radon-proof gas roll and a method for preparing the same and a process for applying the same, but the present invention is not limited to the above examples, i.e., it does not mean that the present invention must be implemented by the above examples.
