oc, relative humidity 85%, test period 1000h, need in test the transmittance conservation rate and the yellowness index that draw often kind of print, transmittance conservation rate and yellowness index measure by the following method.
1. printing opacity conservation rate:
Transmittance measures according to GB/T2410;
Transmittance conservation rate calculates by this formula, the average transmittance %*100% before the average transmittance %/test after transmittance conservation rate=test.
2. yellowness index: yellowness index (△ YI) is analyzed according to GB2409-80.
The wet and heat ageing resistant performance index of several ethylene-vinyl acetate copolymer glued membranes obtained by above-mentioned testing method the results are shown in Table 1.
The wet and heat ageing resistant performance index result of table 1 E1 ~ E4 and C1
Can clearly be found out by table 1: the ethylene-vinyl acetate copolymer glued membrane (E1 ~ E4) that with the addition of carbon free radical trapers compares the ethylene-vinyl acetate copolymer glued membrane (C1) not adding carbon free radical trapers, after hydrothermal aging 1000h, the two transmittance conservation rate is without larger, obvious difference, all more than 90%, yellowness index then E1 ~ E4 is significantly less than C1, and thus the wet and heat ageing resistant performance of E1 ~ E4 is obviously better than C1.
In addition, can also clearly be found out by table 1: with the addition of benzofuranone (namely 5, 7-di-t-butyl-3-(3, 4-3,5-dimethylphenyl) 3H-benzofuran-2-ones and 5, 7-di-t-butyl-3-(2, 3-3,5-dimethylphenyl) mixture of 3H-benzofuran-2-ones) the ethylene-vinyl acetate copolymer glued membrane (E1) of carbon free radical trapers is after hydrothermal aging 1000h, transmittance conservation rate is apparently higher than other carbon free radical trapers of interpolation and the ethylene-vinyl acetate copolymer glued membrane not adding carbon free radical trapers, and yellowness index is minimum, compare the yellowness index of the ethylene-vinyl acetate copolymer glued membrane not adding carbon free radical trapers, difference is up to 2.8 times.
Therefore, the present invention to be frozen etc. except aging resistance except having excellent UV resistant, high-low temperature resistant and moisture-proof, also there is excellent wet-hot aging performance, aging yellowness index is little, adapt to be on active service (comprising the climatope of rare oxygen or anaerobic) for a long time in very harsh, complicated outdoor climatope, long service life.
