Description
Technical Field
The invention belongs to the fields of polymer blending and polymer molding processing, and particularly relates to an alloy material with excellent low-temperature multi-axial impact performance and a preparation method thereof.
Background
Compared with PC/ABS, PC/ASA has better illumination resistance, and PC/ASA is often used to replace PC/ABS in some parts with higher requirements on illumination resistance in the field of automobiles, such as automobile interior rearview mirrors, auxiliary instrument panels and other parts.
The mechanical property of PC/ASA is close to that of PC/ABS in normal temperature environment, but the toughness of PC/ASA is obviously poorer than that of PC/ABS in low temperature environment (such as-30 ℃), but a plurality of automobile parts can have good toughness at low temperature. The low-temperature multi-axial impact property is commonly used for representing the low-temperature toughness of the material, a plurality of host factories put forward the low-temperature multi-axial impact test requirements on the material, and the common PC/ASA alloy material is difficult to meet the low-temperature multi-axial impact test requirements, thereby limiting the use of PC/ASA on automobiles to a certain extent. For example, patent CN109852025A discloses a high impact resistant, high weather resistant PC/ASA alloy material for automobile exterior parts, which comprises the following components: 50-70 parts by weight of polycarbonate; 10-40 parts of styrene-acrylonitrile copolymer; 10-20 parts of impact modifier; 5-10 parts of a compatilizer; 0.2-1 part of antioxidant; 0.3-1 part of light absorber; 0.3-1 part by weight of lubricant; 0.5-1 part of black master batch. The alloy material has excellent impact resistance, especially low temperature impact resistance. However, the low-temperature impact performance of the alloy material only represents low-temperature notch impact, but does not represent low-temperature landing impact, and the low-temperature landing impact can simulate the low-temperature toughness of parts. And the PC/ASA alloy material obtained by blending common PC and the anti-slave modifier has poor low-temperature ball dropping performance.
Therefore, the research on how to improve the low-temperature multi-axial impact property of the PC/ASA has practical and important significance for the application of the PC/ASA in the field of automobiles.
