Abstract

The invention discloses an anti-aging polypropylene composition with a temperature change function and a preparation method and application thereof. The anti-aging polypropylene composition with the temperature change function comprises the following components in parts by weight: 85-99 parts of polypropylene, 0.2-2 parts of an antioxidant, 0.5-5 parts of a dispersing agent and 0.5-4 parts of a temperature change pigment, the average particle size of the antioxidant is 0.2-3 [mu] m, the average particle size of the dispersing agent is 0.2-5 [mu] m, and the average particle size of the temperature change pigment is 1-10 [mu] m. The temperature change pigment is added to the polypropylene matrix, and the particle sizes of the antioxidant, the dispersant and the temperature change pigment are controlled so that the polypropylene composition has the good aging resistance, the antioxidant and the dispersant cannot completely wrap the surface of the temperature change pigment, the good light transmission is maintained, and the temperature change effect is excellent.

Description

technical field [0001] The invention relates to the technical field of polymer materials, and more specifically, relates to an aging-resistant polypropylene composition with a temperature change function, a preparation method and application thereof. Background technique [0002] Polypropylene material has a very wide application market. In addition to its strong plasticity and low price, polypropylene also has good solvent resistance. With the popularity of household appliances, more and more plastic materials, especially polypropylene materials, are used in daily life. [0003] With the continuous pursuit of people's quality of life, some plastic materials with special functions have emerged as the times require. For example, the polypropylene material with temperature change function can display different colors according to the temperature change, so as to directly reflect the temperature of the material. For home appliances such as vacuum flasks, rice cookers, and hum...
