Background
With the gradual implementation of environmental protection policies in recent years, traditional post-treatment processes for surfaces of workpieces such as spraying and water transfer printing are gradually resisted by more and more enterprises due to the defects of strong smell, toxicity, poor production environment and the like, and the spraying-free materials formed in one step through injection molding are slowly accepted and adopted by more enterprises. By adding aluminum powder with a certain proportion and particle size specification in the injection molding process, metal texture similar to aluminum alloy can be formed on the surface of plastic, and the research on the spraying-free material is more and more emphasized due to the convenience of processing, the designability of surface appearance effect and the cost advantage compared with the traditional spraying product.
In the use process of the metal spraying-free ABS material, the phenomenon of performance reduction caused by damp-heat aging deformation or discoloration and the like is often encountered, and the phenomenon of small molecule substance precipitation appears on the surface along with the change of temperature or humidity, and the phenomenon is caused because the damp-heat aging resistance level of the ABS is poor, and the small molecule precipitation is caused because a large amount of small molecule substances are brought in the synthesis or processing process, so that the small molecules are transferred out of the matrix along with the change of external temperature and humidity.

The temperature of each section of the machine body of the double-screw extruder is 180-190 ℃, 190-200 ℃, 210-220 ℃, 220-230 ℃ and the temperature of the machine head is 230-235 ℃ in sequence; the screw rotating speed of the extruder is 400-500 r/min, the cooling water temperature is 25 ℃, the vacuum degree is 1.0MPa, the drying temperature is 80 ℃, and the time is 6h.

the impact property retention rate is the ratio of the notch impact strength after accelerated aging to the notch impact strength before aging; the color difference delta E is the difference value between the color after the accelerated aging test and the color before the aging test.
TABLE 1 concrete compounding ratio (parts by weight) of each component in each example and comparative example
TABLE 2 Performance test data for each of the examples and comparative examples
From examples 1-7, it can be seen that the impact property retention rate of the metal spraying-free ABS material with low precipitation resistance to damp-heat aging is greater than 80% after aging, the color difference Delta E is less than or equal to 2, the metal spraying-free ABS material has excellent damp-heat aging resistance, no obvious precipitation on the surface, and good metal texture. As can be seen from examples 1-7, the emulsion ABS has a high retention rate of impact toughness, and maintains good resistance to wet heat aging under a certain content of the additive; as can be seen from comparative examples 1, 10, 11 and 12 and example 7, the type and content of the antioxidant can affect the stability of the material after the material is subjected to damp-heat aging, the impact retention rate is reduced to a certain extent by increasing the content, the color difference is gradually increased, and the precipitation is easier to occur; as can be seen from comparative examples 2, 13 and 14 and example 7, too high a content of the lubricant results in more residuals, the color difference of the material after accelerated aging is relatively poor and precipitates, and other types of lubricants all precipitate to a certain extent but have less impact; from comparison between comparative example 3 and example 7, it can be seen that the appearance of the material after resistance to wet heat aging is also affected by the increased content of the weathering agent, resulting in increased color difference, and the accelerated aging depends on the type of the weathering agent; as can be seen from comparative example 4 and example 7, too high a content of aluminum powder reduces the retention of impact properties after aging of the material and increases the color difference. It can be seen from comparative examples 6 and 7 and example 7 that the increase of the vacuum degree of the extruder slightly increases the retention rate of the impact strength of the material after accelerated aging, the color difference is significantly increased, the precipitation condition of the surface of the material is greatly improved, mainly due to the increase of the vacuum degree of the extruder, the removal of the small molecular monomer in the ABS is facilitated, the unstable migration of the small molecular monomer in the processing process is one of the main reasons for the precipitation of the material due to the wet heat aging, the improvement of the precipitation further reduces the color difference, and meanwhile, the better retention rate of the impact performance is maintained. From comparative examples 8, 9 and example 7, it can be seen that the impact retention of bulk ABS is better, but the color difference change due to aging degradation is larger, and the combination property is poorer than that of emulsion ABS (preferably MI20 emulsion ABS); in conclusion, the micromolecular auxiliary agents (the antioxidant, the lubricant and the weather-resistant agent) are the important reasons for influencing the wet and heat aging performance of the ABS, and different types of auxiliary agents are selected, and the dosage of different auxiliary agents is adjusted, so that the wet and heat aging performance of the material is favorably improved. The molecular weight of the auxiliary agent is low, the auxiliary agent is easier to migrate out of a matrix in extrusion and injection molding, and the auxiliary agent is also easy to expose on the surface of the material due to instability of the auxiliary agent in a damp heat aging test. And the effects of the substrate, filler and process cannot be neglected.
