Abstract

The invention discloses an environment-friendly bamboo-plastic automobile instrument and a manufacturing method thereof. The environment-friendly bamboo-plastic automobile instrument comprises the following components in parts by weight: 100 parts of polypropylene, 20-30 parts of polyolefin elastomer, 20-40 parts of bamboo fibers and 0.4-0.8 part of a modifying agent. The environment-friendly bamboo-plastic automobile instrument disclosed by the invention is good in forming processability and mechanical performances. According to the environment-friendly bamboo-plastic automobile instrument and the manufacturing method thereof, the pure natural bamboo fibers are used as materials for reducing the using amount of the plastic material, so that the environment-friendly bamboo-plastic automobile instrument is green and environment-friendly; moreover, the manufacturing method is simple and easy to realize large-scale continuous production. The bamboo fibers are added, so that the environment-friendly bamboo-plastic automobile instrument has excellent antibacterial performances.

Description

technical field [0001] The invention relates to an automobile instrument panel and a preparation method thereof, in particular to an environment-friendly bamboo-plastic automobile instrument panel and a preparation method thereof. Background technique [0002] Automotive interior parts, mainly refers to the automotive products used in the interior modification of the car, involving all aspects of the car interior, such as glove boxes, car seat back panels, car inlays, car side panels, pillar guards, door panels, car instrumentation Panels, car sub-dashboards, glove boxes, radio boxes and central consoles are all automotive interior products.
