Abstract

The invention discloses a low surface temperature polypropylene composition and a preparation method and application thereof. The low surface temperature polypropylene composition comprises 47 to 85 parts of polypropylene resin and 5 to 20 parts of an elastomer. The low surface temperature polypropylene composition comprises 1000-4000ppm of a pigment and the pigment comprises one or more of rutile-type pigments, spinel-type pigments and hematite-type pigments. The preparation method comprises uniformly mixing the polypropylene resin, the pigment and the elastomer, adding the mixture into a twin-screw extruder, carrying out melting mixing and carrying out extrusion granulation to obtain the low surface temperature polypropylene composition. The low surface temperature polypropylene composition has high near-infrared reflectance. After same-frequency near infrared radiation of the low surface temperature polypropylene composition and other polypropylene compositions on the market for some time, the low surface temperature polypropylene composition has a lower surface temperature. The low surface temperature polypropylene composition can be widely used for fascia consoles, auxiliary fascia consoles, door plates, chair seats or bumpers.

Description

technical field [0001] The invention relates to the technical field of plastic modification, in particular to a polypropylene composition with low surface temperature and its preparation method and application. Background technique [0002] Polypropylene has strong competitiveness in the automotive industry, but because of its low modulus, heat resistance, and poor impact strength, it cannot be directly used as auto parts. All used in cars are modified polypropylene products. Its heat resistance can be increased from 80°C to 145°C~150°C, and it can withstand high temperature for 750~1000 hours without aging or cracking. But in the hot summer, after the car is exposed to sunlight, the temperature of various accessories in the car will rise sharply, and the driver and passengers will be very uncomfortable when entering the car, and accessories made of modified polypropylene will even be damaged. To burn the human skin, you can only turn on the air conditioner and wait for the...
