Embodiment 1
[0060] Example 1: The TPE-S substrate is composed of N250 white oil-extended SEBS-G1654 and PP-R370Y, and the composite system composed of hexaphenoxycyclotriphosphazene and organically modified MDH H7C / 2 is flame-retardant agent, the ratio of the above two flame retardants is 1:1, the PPO-S201A of Japan Asahi Kasei Co. 1 in. From the test results of Example 1 in Table 4, it can be found that the prepared flame-retardant composite material and the extruded wire have good mechanical properties and flame-retardant properties, the tensile strength of the wire is 16.5Mpa, the elongation at break is 413%, and the UL94 vertical burning The test result is V-0 level, and the UL1581 test result is VW-1 level. After aging at 136°C for 168 hours, the retention rate of tensile strength is 92%, and the retention rate of elongation at break is 94%, both of which greatly exceed the provisions of the UL1581 thermal aging standard (≥75%); there is no cracking phenomenon after thermal shock, a...
Embodiment 2
[0061] Example 2: SEBS-G1650 is used instead of SEBS-G1654, and the base material is composed of N250 white oil extension and PP-R370Y, and the composition of other components is equal to that of Example 1. From the test results of Example 2 in Table 4, it can be found that compared with Example 1, the tensile strength of the prepared flame-retardant composite material and the extruded wire, and the strength retention rate after aging are slightly reduced, but they are still far from It is higher than the lower limit requirement of the UL standard, except that the melt index of the material increases from 2.5g / 10min to 8.6g / 10min, and other physical properties generally change little. Overall, the wires and materials have excellent comprehensive properties, meeting the requirements of charging wires for electric vehicles. At the same time, compared with Example 1, the fluidity of the material in Example 2 is increased, and it is easier to extrude wires with thinner walls.
Embodiment 3
[0062] Example 3: SEBS-G1650 is used to replace 50% of the added amount of SEBS-G1654, and the TPE-S substrate is composed of white oil N250 oil-extended and PP-R370Y, and the composition of other components is equivalent to that of Example 1 and Example 2 composition. From the test results of Example 3 in Table 4, it can be found that the properties of the prepared flame-retardant composite material and the extruded wire are between those of Example 1 and Example 2, and the overall performance is good, which fully meets the requirements of the charging wire for electric vehicles. Requirements.
[0063] Comparative Example C-1: On the basis of Example 3, keep the total amount of hexaphenoxycyclotriphosphazene and MDH H7C / 2, and only change the addition ratio of the two flame retardants (from the original 1:1 to 2:1), and the other components and ratios remained unchanged. From the test results of Comparative Example C-1 in Table 5, it can be found that the flame-retardant pe...
