Abstract

The invention discloses a polyolefin master batch as well as a preparation method and application thereof, and belongs to the technical field of high polymer materials. The polyolefin master batch comprises the following components in parts by weight: 35-78 parts of non-polar polyolefin resin; 10 to 30 parts of expanded graphite; 1-3 parts of a coupling agent; 10 to 30 parts of a compatilizer; 2 to 10 parts of an antioxidant; and 0.1-2 parts of a lubricant. The crystallinity of the non-polar polyolefin resin is 60-90%, the test method is a DSC method, and the test condition is that the heating and cooling rate is 10 DEG C / min. According to the polyolefin master batch disclosed by the invention, through the synergistic effect of the non-polar polyolefin resin and the expanded graphite, the long-term aging resistance effect of the ABS composite material is effectively improved. The invention discloses an ABS (Acrylonitrile Butadiene Styrene) composite material with long-term thermal aging resistance. The retention rate of tensile strength tested after aging at 100 DEG C for 1000 hours is still 92% or above.

Description

technical field [0001] The invention relates to the technical field of polymer materials, and more particularly, to a polyolefin masterbatch, a preparation method and application thereof, and a long-term heat aging-resistant ABS composite material, a preparation method and application thereof. Background technique [0002] ABS is a terpolymer of three monomers of acrylonitrile (A), butadiene (B) and styrene (S), because of its excellent comprehensive physical and mechanical properties, dimensional stability, electrical properties, wear resistance It is widely used in the interior and exterior of automobiles because of its properties such as chemical resistance, dye resistance, finished product processing and mechanical processing. [0003] In recent years, the automotive industry has paid more and more attention to long-term thermal aging. The aging of automobile interiors is mainly due to the high temperature in summer, which will cause thermal aging of automobile interiors...
