Third, performance detection and analysis
Test one: easy printing Performance test
Test subjects: the printed oil-and voltage-resistant insulating elastomer materials prepared in examples 1 to 14 were used as test samples 1 to 14, and the elastomer materials prepared in comparative examples 1 to 5 were used as control samples 1 to 5.
The test method comprises the following steps: the test samples 1-14 and the comparison samples 1-5 are processed by a cold extrusion molding machine to obtain rectangular plates of 10cm by 1cm, 19 groups are obtained, 10 small samples are arranged in each group, the 190 rectangular plates are subjected to coding treatment in the upper, lower, left and right directions of the rectangular plates by a coding printing machine, and the effect of coding printing integrity is detected after the rectangular plates are dried and placed for 5 minutes, 20 minutes and 1 hour at normal temperature.
And (3) test results: as can be seen from tables 1 and 2, the test samples 1 to 14 were good in integrity, and exhibited a phenomenon in which a complete printed pattern was not partially formed, as compared with the control samples 1 to 3, and thus it was found that the test samples 1 to 14 were better in the effect of easy printing than the control samples 1 to 3. Secondly, after the test sample 1-14 was left for a period of time at room temperature, the color fading of the test sample 1-14 was not observed, while the color fading of the control sample 2 was significant, and the color fading phenomenon occurred in 36-30% of the printed codes of the control sample 1 and the control sample.
TABLE 1 detection Standard for easy printing of rectangular plate
TABLE 2 easy-to-print Performance test results for test samples 1-14 and control samples 1-5
And (2) test II: oil-resistant and voltage-resistant
Test subjects: the printed oil and voltage resistant insulating elastomer materials prepared in examples 1 to 14 were used as test samples 1 to 14, and the elastomer materials prepared in comparative examples 1 to 7 were used as control samples 1 to 7.
The test method comprises the following steps: and (3) carrying out cold extrusion molding on the test samples 1-14 and the reference samples 1-7 to obtain rectangular plates of 10cm by 1cm, and carrying out detection on the 21 rectangular plates by a GB/T3333 cable paper power frequency voltage breakdown tester to obtain a result.
The test samples 1-14 and the control samples 1-7 were immersed in petroleum according to the requirements of UL1581 to determine the rated oil-resistant temperature and the oil-immersion aging condition.
And (3) test results: as can be seen from Table 3, the breakdown voltages of the test samples 1 to 14 were all greater than 100KV/mm, while the voltage resistance of the comparative samples 1 to 7 was less than 100KV/mm, and thus they had good voltage resistance. Secondly, it can be seen from comparative samples 1 to 7 that the performance of comparative sample 1 is better than that of comparative samples 2 to 3, and thus it can be seen that the performance of the blended material with polypropylene alone is better than that with polyethylene alone. Secondly, the performance of the sample 1-14 is better than that of the comparison sample 1-7, and compared with the examples 4-6 and the comparison examples 4-5, the performance is poorer than that of the oil immersion aging effect compounded by the antioxidant 1010 or the antioxidant 168 when only the antioxidant is added. Meanwhile, the oil immersion aging is best when the weight ratio of the antioxidant 1010 to the antioxidant 168 is 1: 1.2.
