TABLE 1 concrete compounding ratio (parts by weight) of each component in each example and comparative example
Figure BDA0003388536670000051
TABLE 2 Performance test data for each of the examples and comparative examples
Figure BDA0003388536670000061
Figure BDA0003388536670000071
As can be seen from examples 1-9, the weather-resistant, high temperature and high humidity resistant ABS composition has good compatibility, the retention rate of impact property after aging is more than 85%, the color difference Delta E is less than 2, and the composition has excellent weather-resistant, high temperature and high humidity resistant property and good molding processability. As can be seen from examples 1 and 2, SAN having a higher AN content has a poor compatibility with PMMA and EMMA, and the impact toughness retention of the composition after accelerated aging is slightly reduced. As can be seen from examples 3 and 4, the ABS high rubber powder with too high a butadiene content has relatively poor impact toughness retention and poor color difference after accelerated aging of the composition due to more residual monomers. From the comparison between example 5 and example 6, the melt flow rate of PMMA is too low, and the melt viscosity difference with the composition system is too large, so that the compatibility of the system is affected, and the impact property retention rate and the color difference of the composition after accelerated aging are relatively poor. In comparison between examples 5 and 10, the melt flow rate of PMMA is too high, which reduces the impact retention and color difference of the composition. From examples 7 and 8, it can be seen that when the melt flow rate of EMMA is relatively low, EMMA is not easily enriched on the surface of the product during injection molding, and the barrier effect on light, heat, oxygen and water vapor is reduced during accelerated aging, thereby affecting the impact retention rate and color difference. As can be seen from comparative example 1 and comparative example 5, the introduction of the organic modified montmorillonite improves certain weather resistance, high temperature resistance and high humidity resistance. As can be seen from comparative example 2 and example 1, the addition ratio of the organic modified montmorillonite is too high, and the weather resistance, high temperature resistance and high humidity resistance of the composition are reduced. As can be seen from the comparison of comparative example 3 and example 1, EMMA resin can improve the high temperature and high humidity resistance of ABS. As can be seen from the comparison between comparative example 4 and example 1, PMMA can further improve the compatibility between ABS and EMMA, and improve the weather resistance, high temperature resistance and high humidity resistance of the composition.
