Table 2 is a table of test results data for each example and comparative example:
TABLE 2 test result data table of each example and comparative example
By combining the embodiment 1, the embodiment 2 and the embodiment 41 and combining the table 2, the proportion of the modified nylon 66 is more accurate, the aging resistance of the modified nylon 66 is more stable, and the influence of aging on the binding performance of the binding tape is less by the addition amounts of the nylon 66, the maleic anhydride grafted POE flexibilizer, the polytetrafluoroethylene, the isobutanolamine, the compatilizer, the coupling agent, the lubricant, the antioxidant, the ultraviolet resistant agent, the heat stabilizer, the 7-dehydrocholesterol and the carbon black.
By combining the embodiment 2, the embodiment 3 and the embodiment 4 and combining the table 2, the proportion of the modified nylon 66 is more accurate and the aging resistance of the modified nylon 66 is more stable by adjusting the addition amount of the nylon 66.
By combining the embodiment 2, the embodiment 5 and the embodiment 6 and combining the table 2, the proportion of the modified nylon 66 is more accurate by adjusting the addition amount of the maleic anhydride grafted POE, the aging resistance of the modified nylon 66 is more stable, and the influence of aging on the binding performance of the binding tape is smaller.
Combine embodiment 2, embodiment 7 and embodiment 8 and combine table 2, through the addition of adjustment polytetrafluoroethylene for the ratio of modified nylon 66 is more accurate, and modified nylon 66's ageing-resistant performance is more stable, and ageing is less to ribbon ligature performance's influence.
Combining examples 2, 9 and 10 with table 2, it can be seen that as the amount of isobutanol amine added increases, the tensile strength of the unaged tie increases and then decreases, the loss of tensile strength after aging of the tie decreases and then increases, and the aging resistance of the tie increases and then decreases. The reason is that when the isobutanolamine is used as a dispersing agent to improve the dispersion uniformity of all raw materials of the modified nylon 66, the pH value of the modified nylon 66 mixture can be adjusted, an acid environment is provided for the decomposition of 7-dehydrocholesterol, and the efficiency of ultraviolet absorption of the ergocalciferol which is a decomposition product of the 7-dehydrocholesterol is improved, so that the decomposition efficiency of the nylon 66 is reduced, the aging resistance of the modified nylon 66 is improved, and the adverse effect of aging on the binding performance of a binding tape is reduced.
By combining the embodiment 2, the embodiment 11 and the embodiment 12 and combining the table 2, the proportion of the modified nylon 66 is more accurate by adjusting the addition amount of the antioxidant, the aging resistance of the modified nylon 66 is more stable, and the influence of aging on the binding performance of the binding tape is smaller.
By combining the embodiment 2, the embodiment 13 and the embodiment 14 and combining the table 2, the proportion of the modified nylon 66 is more accurate by adjusting the addition amount of the compatilizer, the aging resistance of the modified nylon 66 is more stable, and the influence of aging on the binding performance of the binding tape is smaller.
By combining the embodiment 2, the embodiment 15 and the embodiment 16 and combining the table 2, the proportion of the modified nylon 66 is more accurate by adjusting the addition amount of the coupling agent, the aging resistance of the modified nylon 66 is more stable, and the influence of aging on the binding performance of the binding tape is smaller.
By combining the embodiment 2, the embodiment 17 and the embodiment 18 and combining the table 2, the proportion of the modified nylon 66 is more accurate by adjusting the addition amount of the lubricant, the aging resistance of the modified nylon 66 is more stable, and the influence of aging on the binding performance of the binding tape is smaller.
By combining the embodiment 2, the embodiment 19 and the embodiment 20 and combining the table 2, the proportion of the modified nylon 66 is more accurate, the aging resistance of the modified nylon 66 is more stable, and the influence of aging on the binding performance of the binding tape is less by adjusting the addition amount of the ultraviolet resistant agent.
By combining the embodiment 2, the embodiment 21 and the embodiment 22 and combining the table 2, the proportion of the modified nylon 66 is more accurate by adjusting the addition amount of the heat stabilizer, the aging resistance of the modified nylon 66 is more stable, and the influence of aging on the binding performance of the binding tape is less.
By combining the embodiment 2, the embodiments 23 to 30 and the table 2, the proportion of the modified nylon 66 is more accurate, the aging resistance of the modified nylon 66 is more stable, and the influence of aging on the binding performance of the binding belt is less by adjusting the addition amounts of the 7-dehydrocholesterol and the carbon black.
In combination with example 2, example 24 and example 29, and with Table 2, it can be seen that increasing the amount of 7-dehydrocholesterol added without changing the amount of carbon black added increased the tensile strength of the unaged tie first and then decreased, and the loss of tensile strength after aging of the tie first and then increased. The reason is that the 7-dehydrocholesterol is decomposed under the action of ultraviolet rays and heat to generate ergocalciferol which effectively inhibits the growth of bacteria, so that the ribbon is not easy to age due to the influence of microorganisms; the ergocalciferol captures free radicals generated by photolysis of the nylon 66, so that the photodegradation rate of the nylon 66 is reduced, and the aging resistance of the modified nylon 66 is improved. The addition amount of the 7-dehydrocholesterol is continuously increased, the 7-dehydrocholesterol partially positioned in the ribbon is not easy to contact with ultraviolet rays, the content of ergocalciferol obtained by decomposing the 7-dehydrocholesterol is reduced, and the loss rate of the tensile strength of the ribbon is increased.
As can be seen by combining example 2, comparative example 1, comparative example 2 and comparative example 3, and by combining Table 2, the rate of loss of tensile strength after the aging treatment of the ribbon is reduced by the addition of 7-dehydrocholesterol.
Combining example 2, example 26 and example 27 with table 2, it can be seen that, in the case where the amount of added 7-dehydrocholesterol is not changed, the amount of added carbon black is increased, the tensile strength of the ribbon without aging treatment is increased and then decreased, and the loss of tensile strength after aging treatment of the ribbon is decreased and then increased, because the carbon black absorbs ultraviolet rays and visible light, so that the photodecomposition rate of nylon 66 is decreased, the ultraviolet resistance of the ribbon is improved, and the aging rate of the ribbon is decreased. The carbon black content is increased, the ultraviolet absorption rate of the carbon black is increased, and the heat energy converted by the carbon black absorbing ultraviolet and visible light improves the decomposition efficiency of the 7-dehydrocholesterol, so that the aging resistance of the modified nylon 66 is improved.
It can be seen from the combination of example 2, comparative example 1, comparative example 2 and comparative example 3, and from Table 2 that the tensile strength loss rate after the aging treatment of the ribbon decreases with the addition of carbon black.
Combining example 2, example 31, example 32 and example 33 with combination 2, it can be seen that the tensile strength of the unaged tie increases and then decreases, and the loss rate of the tensile strength after the aging treatment of the tie decreases and then increases, as the amount of tetrachloroisophthalonitrile added increases. The reason is that when the bandage is used in a dark environment, 7-dehydrocholesterol is not easy to decompose, and tetrachloroisophthalonitrile inhibits the breeding of mould and the like on the bandage; under illumination, tetrachloroisophthalonitrile and ergocalciferol jointly inhibit the growth of microorganisms, and tetrachloroisophthalonitrile has good illumination resistance and heat resistance stability, so that the microbial resistance of the ribbon under illumination is further improved; the tetrachloroisophthalonitrile and the ergocalciferol are used in a matched manner, so that the aging resistance of the ribbon under different environments is improved. With the continuous increase of the adding amount of tetrachloroisophthalonitrile, the content of the slow release stabilizer is reduced, the aging resistance of the modified nylon 66 is reduced, and the loss rate of the tensile strength of the cable tie after aging treatment is increased.
Combining example 2, example 34, example 35 and example 36, and combining table 2, it can be seen that as the amount of zinc powder added increases, the tensile strength of the unaged tie increases and then decreases, and the loss of tensile strength of the tie after aging decreases and then increases. The reason is that the zinc powder inhibits the breeding of strains on the binding belt and improves the bacterial resistance of the binding belt, so that the aging resistance of the modified nylon 66 is improved; under illumination, the nylon 66 is degraded to generate free radicals, and the zinc powder captures the free radicals, so that the degradation rate of the nylon 66 is reduced, and the aging resistance of the modified nylon 66 is improved; the zinc powder and the 7-dehydrocholesterol are adsorbed mutually, and the zinc powder is uniformly distributed in the mixture under the drive of the 7-dehydrocholesterol in the mixing stage of the modified nylon 66 raw material, so that the distribution uniformity of the zinc powder in the ribbon is improved, the zinc powder can fully play a role when the ribbon is used, and the aging resistance of the modified nylon 66 is further improved. The addition amount of zinc powder is continuously increased, the content of the slow release stabilizer is reduced, and the ultraviolet resistance of the modified nylon 66 is reduced, so that the aging resistance of the cable tie is reduced, and the loss rate of the tensile strength of the cable tie after aging treatment is increased.
Combining example 2 and example 37 with table 2, it can be seen that the increase of the combustion improver effectively increases the limiting oxygen index of the cable tie, so that the flame retardant property of the cable tie is enhanced.
It can be seen by combining example 38, example 39 and example 40 with table 2 that as the amount of flame retardant added increases, the limiting oxygen index of the tie increases, but the tensile strength of the tie decreases and the rate of loss of tensile strength after the aging treatment of the tie increases. The reason is that the flame retardant prevents the antioxidant, the 7-dehydrocholesterol and the carbon black from contacting with air, thereby reducing the ultraviolet absorption efficiency of the ribbon, and the photolysis rate of the nylon 66 is increased, thereby reducing the aging resistance of the ribbon.
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.
