Table 2 detection of radiation resistance of radiation resistant fabric
Figure BDA0002849357010000101
Figure BDA0002849357010000111
As can be seen from the data in examples 1 to 7 and table 2, the radiation-resistant fabrics prepared in examples 1 to 7 have better shielding effectiveness for electromagnetic waves of different frequencies, and after being washed for 10 times, the electromagnetic shielding effectiveness is not significantly reduced.
In examples 8 to 10, before the pretreatment of the nano silver fiber, the surface impurities are removed by treating with deionized water, acid solution, etc., so that the components such as indium are uniformly and densely deposited on the surface of the nano silver fiber, and the oxidation resistance of the anti-radiation fabric is improved, thereby improving the electromagnetic shielding performance.
In examples 11 to 12, the surface of the nano-silver fiber subjected to magnetron sputtering was coated with components such as an organic silicon modified acrylic emulsion, so that the nano-silver fiber had a high washing effect.
In examples 13 to 15, the radiation-resistant composite fibers were added, so that the electromagnetic shielding performance of the radiation-resistant fabrics prepared in examples 13 to 15 was enhanced, and the electromagnetic shielding effect on the electromagnetic waves having frequencies of 30MHz, 300MHz, and 3000MHz was significantly enhanced as compared with examples 1 to 12.
In example 16 and example 17, because the protein film powder and the poly (lactic-co-glycolic acid) copolymer are not added when the anti-radiation composite fiber is prepared, it can be seen from the data in table 2 that the electromagnetic shielding effect of example 16 and example 17 is not greatly changed compared with examples 13-15, but after 10 times of washing, the electromagnetic shielding effectiveness of the anti-radiation fabric to different frequencies is obviously reduced compared with that before washing, which shows that the water resistance effect of the anti-radiation composite fiber can be effectively increased by the protein film powder and the poly (lactic-co-glycolic acid).
In example 18, alpha-cycloalanine is not added, and as can be seen from the data in table 2, the electromagnetic shielding performance of the radiation-resistant fabric is significantly reduced compared with examples 13 to 15, but after 10 times of washing, the electromagnetic shielding performance is not significantly reduced compared with that before washing, which indicates that the alpha-cycloalanine can effectively enhance the electromagnetic shielding performance of the radiation-resistant composite fiber.
In example 19, the loofah sponge and the pomegranate rind are not added, in example 20, the loofah sponge and the passion fruit shell are not added, and in example 21, the passion fruit shell and the pomegranate rind are not added, and it can be seen from the data in table 2 that the electromagnetic wave shielding performance of the radiation-resistant fabric prepared in examples 19 to 21 is reduced compared with that of examples 13 to 15, which indicates that the compound of the three substances, namely the loofah sponge, the pomegranate rind and the passion fruit shell, has a good radiation-resistant effect.
In example 22, the surface of the nano silver fiber is cleaned, the nano silver fiber is coated with the organic silicon modified acrylic emulsion after magnetron sputtering, and then the nano silver fiber and the organic silicon modified acrylic emulsion are mixed with the anti-radiation composite fiber, so that the anti-radiation fabric prepared in examples 1 to 5 is improved in anti-radiation performance, strong in water washing resistance, and still has strong electromagnetic shielding performance after being washed for 10 times.
Comparative example 1 since the nano silver fiber is not subjected to the magnetron sputtering pretreatment, the radiation resistant fabric prepared in comparative example 1 has a reduced shielding effect on electromagnetic waves compared to examples 1 to 7, and the water resistance effect of the radiation resistant fabric is reduced compared to examples 13 to 15.
In comparative examples 2 to 5, any component used in the pretreatment of the nano silver fiber was not added, the electromagnetic shielding effect of the anti-radiation fabric prepared in comparative examples 2 to 5 was not significantly changed compared to examples 1 to 7, and the electromagnetic shielding effect before and after washing was not significantly changed compared to examples 1 to 7.
Comparative example 6 the electromagnetic shielding effectiveness and the water resistance effect of the radiation resistant fabric prepared by simply mixing the nano silver fibers with the pretreatment components are not much different from those of examples 1 to 7.
Comparative example 7 is a radiation resistant fabric prepared by the prior art, and the electromagnetic shielding effect is inferior to that of examples 1 to 5 of the present application.
Secondly, detecting the oxidation and color change resistance: the initial shades of the radiation-resistant fabrics prepared in the examples and comparative examples were measured with a Canon canoscanLIDE100 shade scanner, recorded in table 3, and then subjected to the following tests:
1. and (3) detecting the oxidation resistance: placing the anti-radiation fabric in a sodium sulfide solution with the concentration of 5%, carrying out constant-temperature water bath for 1 hour at 30 ℃, then fully washing and drying, detecting the gray level after accelerated vulcanization by using a scanner, and recording the detection result in a table 3; 2. and (3) oxidation and water resistance fastness: a washing test was carried out in accordance with GB/T3921.3, and the gray scale of the radiation-resistant fabric after washing was scanned by a scanner and the detection results were recorded in Table 3.
TABLE 3 detection of antioxidant Properties of radiation resistant Fabric
Figure BDA0002849357010000121
Figure BDA0002849357010000131
As can be seen by combining the data in examples 1 to 7 and table 3, the radiation-resistant fabrics prepared in examples 1 to 7 have less surface gray level reduction and less gray level change after accelerated vulcanization compared with those before vulcanization, and the gray level change is less compared with that before washing after washing, which indicates that the radiation-resistant fabrics prepared in the present application have better oxidation resistance and can prevent silver fibers from oxidative discoloration.
In the embodiment 8-9, when the nano silver fiber is pretreated, the operations such as washing, pickling and the like are performed on the nano silver fiber, so that the deposition of the antioxidant component on the surface of the nano silver fiber is more uniform and compact, and the oxidation resistance of the radiation-resistant fabric is further improved.
In examples 10 to 11, the surface of the nano-silver fiber subjected to magnetron sputtering is coated with the organic silicon modified acrylic emulsion and 3-mercaptodimethylsilane, so that the radiation-resistant fabric has small gray level change after accelerated vulcanization, and the gray level value reduction after washing is smaller than that of examples 1 to 7, and the washing-resistant effect is improved.
In examples 13 to 15, the radiation-resistant composite fibers were added to the warp yarns, and the gray values of the radiation-resistant fibers after accelerated vulcanization are increased compared with those of examples 1 to 7, which indicates that the addition of the radiation-resistant composite fibers can also improve the oxidation resistance of the radiation-resistant fabric.
In example 16, the eggshell membrane powder is not added, and in example 17, the poly (lactic-co-glycolic acid) copolymer is not added, and the data in table 3 show that the grey value of the radiation-resistant fabric prepared in example 16 and example 17 is obviously reduced after the fabric is washed by water, which shows that the eggshell membrane powder and the poly (lactic-co-glycolic acid) copolymer can enhance the washing-resistant effect of the radiation-resistant fabric.
Examples 18-21 produced radiation resistant fabrics that varied significantly from examples 13-15, both before and after vulcanization and before and after washing.
In example 22, when the anti-radiation fabric is prepared, the nano silver fibers are washed, pickled, the antioxidant component is sputtered in a magnetron manner, the organic silicon modified acrylic emulsion is coated, and the anti-radiation fabric is blended with the anti-radiation composite fibers, so that the gray value of the prepared anti-radiation fabric after vulcanization has small change, insignificant color change and good anti-oxidation effect compared with the gray value before vulcanization, and the gray value of the fabric after washing and before washing has small change and strong washing resistance.
In comparative example 1, because the nano silver fibers are not pretreated, the anti-radiation fabric prepared in comparative example 1 has obvious color change and larger gray value reduction after vulcanization, and the gray value is reduced and the color change is obvious after water washing, which shows that the untreated nano silver fibers have poor oxidation resistance and are easy to change color.
In the comparative example 2, no indium is added, in the comparative example 3, no 2, 2-dibutyldihydro-6H-1, 3, 2-oxathiin hexacyclic-6-ketone is added, in the comparative example 4, no ruthenium tetroxide is added, in the comparative example 5, no traditional Chinese medicine extract is added, after the radiation-resistant fabric prepared in the comparative examples 2-5 is vulcanized in an accelerated manner, the surface gray level is obviously reduced, the color of the radiation-resistant fabric is darkened, and the oxidation phenomenon occurs, which shows that the nano silver fiber is subjected to magnetron sputtering by using indium, 2-dibutyldihydro-6H-1, 3, 2-oxathiin hexacyclic-6-ketone, ruthenium tetroxide and the traditional Chinese medicine extract, and the oxidation resistance of the nano silver fiber can be effectively improved.
In the comparative example 6, when the nano silver fiber is pretreated, indium, 2-dibutyldihydro-6H-1, 3, 2-oxathiostannum hexacyclo-6-ketone, ruthenium tetroxide and the traditional Chinese medicine extract are simply mixed with the nano silver fiber, and the nano silver fiber obtained by pretreatment is made into the anti-radiation fabric, so that the anti-radiation fabric has poor oxidation resistance and is easy to discolor.
Comparative example 7 is the anti-radiation fabric prepared by the prior art, the nano-silver fiber contained in the fabric has poor oxidation resistance, is easy to discolor, and has obvious oxidation after water washing.
The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
