Abstract

The invention discloses a polypropylene composite material and a preparation method thereof. The composite material comprises the following raw materials in parts by weight: (1) 35-85 parts of polypropylene; (2) 5-35 parts of a toughening agent; (3) 5-40 parts of a mineral filler; (4) 0.3-15 parts of a composite antistatic agent, wherein the composite antistatic agent is composed of a polymer permanent antistatic agent and an inorganic permanent antistatic agent, and the composite material can also comprise a porous adsorbent, an acid acceptor, an antioxidant and a light stabilizer. Accordingto the invention, the polypropylene composite material disclosed by the invention adopts the composite antistatic agent, has low volume resistivity, and can meet the antistatic and dustproof requirements of automotive trim materials; by adding deodorants with different smell removal mechanisms, the smell of the product is low, so the product can meet the requirements of automotive trim materials for smell; and the polypropylene composite material has characteristics of excellent mechanical properties, simple preparation process, good processability, low cost, and facilitation of large-scale commercial production.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a polypropylene composite material for permanent antistatic and low-odor automobile interior decoration and a preparation method thereof. Background technique [0002] With the rapid development of the automobile industry, the requirements for lightweight, energy saving and emission reduction are becoming more and more stringent, and more and more plastic materials are applied to the interior and exterior parts of automobiles. Polypropylene (PP) has been widely used in instrument panels, door panels, floor mats, trunk covers, and pillars in recent years because of its low density, low price, good mechanical properties, and excellent processing properties. And other automotive interior parts. [0003] Although polypropylene resin has many advantages as a material for automotive interior parts, because its molecular chain is non-polar, its volume resistivity ...
