Performance detection
The test method comprises the following steps: the anti-aging nitrile latex gloves of examples 1-4 were subjected to thermal aging tests at 70 + -2 deg.C for 166 + -2 h in a thermal aging test chamber. Specific detection results are shown in table 1.
TABLE 1 Performance test
| Group of | Tensile strength/MPa | Elongation at break/%) |
| Example 1 | 28 | 585.0 |
| Example 2 | 29 | 586.8 |
| Example 3 | 26 | 583.2 |
| Example 4 | 27 | 584.4 |
| Unaged product | 31 | 600.0 |
As seen from Table 1, the aged products of examples 1-4 showed less reduction in tensile strength at break than the unaged product, wherein the elongation at break of the product of example 1 was reduced by 2.5% compared to the unaged product; the elongation at break of the product of example 2 is reduced by 2.2% compared to the unaged product; the elongation at break of the product of example 3 was reduced by 2.8% compared to the unaged product; the elongation at break of the product of example 4 was reduced by 2.6% compared to the unaged product.
