Problems solved by technology

However, the use of tougheners with high and low temperature properties can indeed improve the low temperature impact properties of materials, but because many low temperature toughness modifiers are not compatible with PC / ABS, adding a large amount will easily lead to other appearance and physical properties. Deterioration, in addition, its high cost will inevitably lead to an increase in material cost

Abstract

The invention discloses PC / ABS alloy with high low-temperature notched impact strength and a preparation method thereof. The PC / ABS alloy comprises the following compositions in parts by weight: 40-80 parts of PC, 20-50 parts of ABS, 0.5-10 parts of AS, 2-10 parts of a flexibilizer, 0.5-5 parts of a compatibilizer, 0.1-1 part of an anti-oxidant and 0.1-1 part of a lubricant. By adding low-molecular AS, the fluidity of the material is improved, the processing window of the material is expanded, and the reject ratio caused by post-processing is reduced. The prepared PC / ABS alloy keeps various mechanical properties basically unchanged while guaranteeing excellent low-temperature notched impact strength, and is especially applicable to automobiles internal / external decorative parts with relatively high requirement on low-temperature property, such as instrument panels, rearview mirrors, door handles, luggage supports and the like.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a PC / ABS alloy with high and low temperature notch impact and a preparation method thereof. Background technique [0002] PC / ABS alloy is an amorphous engineering plastic with excellent impact strength, heat resistance, high rigidity and other properties, and is widely used in automobiles, electronics, home appliances and other fields. Since automobiles need to be used in various complex environments, where there are many places with low temperature, higher requirements are put forward for the low temperature performance of automobile materials. Therefore, in these occasions, PC / ABS alloys need to have higher low temperature resistance to ensure product performance and vehicle safety. [0003] At present, the high and low temperature impact properties of PC / ABS alloys are mainly achieved by adding toughening agents with better low temperature toughness. [0004] In the 10172424...
