Abstract

The invention discloses an anti-aging ABS-TPU plastic alloy composed of the components of, by weight: 100 parts of ABS, 15-25 parts of TPU, and 0.5-1.5 parts of an anti-aging agent. With the ABS-TPU plastic alloy, TPU stress resistance and cracking resistance are sufficiently improved; stabilities of TPU against oxygen, ozone, and ultraviolet rays can be improved; ABS impact resistance, wearing resistance, and forming and processing performances can be improved. The plastic alloy can be used for producing auto parts, pulleys, low-load gears, and gaskets. The plastic alloy has excellent thermal-aging resistance, and can be applied under extreme-high-temperature environments.

Description

technical field [0001] The invention relates to a plastic alloy, in particular to an anti-aging ABS-TPU plastic alloy. Background technique [0002] ABS resin (acrylonitrile-styrene-butadiene copolymer, ABS is the acronym for AcrylonitrileButadieneStyrene) is a thermoplastic polymer material structure with high strength, good toughness and easy processing. [0003] ABS is a general-purpose thermoplastic engineering plastic developed in the 1940s. It is a plastic variety with excellent comprehensive mechanical properties. It not only has good rigidity, hardness and processing fluidity, but also has high toughness. It can be injected, extruded or heated. forming. [0004] Thermoplastic polyurethane elastomer, Thermoplastic polyurethane, referred to as TPU. [0005] However, the current ABS-TPU plastic alloy has poor aging resistance. Contents of the invention [0006] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the p...
