The invention discloses a plastic for automobile inner ornaments and a preparation method thereof. The plastic for automobile inner ornaments comprises the following components in parts by weight: 30-50 parts of polypropylene, 20-40 parts of ethylene propylene diene monomer, 20-40 parts of LDPE (low-density polyethylene) resin and 0.5-1.5 parts of anti-yellowing agent. The preparation method comprises the following steps: proportionally weighing the raw materials, uniformly mixing, melting and compounding, and extruding and granulating. The plastic for automobile inner ornaments has favorable light aging resistance, and can be made into cockpit outer lateral side plates, small covers, lateral side plate inner plates, inner lateral side plate plastic parts, passenger seat outer lateral side plates, door plate armrest frameworks, door insertion plate frameworks, door insertion plates and other automobile inner ornaments by an injection molding technique.
Description
technical field [0001] The invention relates to a plastic material and a preparation method thereof, in particular to a plastic for automotive interior parts and a preparation method thereof. Background technique [0002] Automotive interior parts, the English name Automotive Interior, 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 inlay panels, car side panels, and pillar guards , Door panels, car sub-dashboards, glove boxes, radio boxes and central consoles are all automotive interior products. The automotive interior system is an important part of the car body, and the design workload of the interior system accounts for more than 60% of the car styling design workload, far exceeding the car shape, and is one of the most important parts of the car body. [0003] In the current technology, plastic materials are usually used for automotive interi...
