Abstract
The invention relates to an automobile door trim prepared from a polypropylene / clay nano composite material, particularly an automobile door trim prepared from a composite material, belonging to the field of new materials for automobiles. The automobile door trim is prepared from the following raw materials in parts by weight: 80-86 parts of polypropylenecopolymer, 6-10 parts of phyllosilicate inorganic nano filler, 2-10 parts of polymer with polyolefine copolymer, 0.5-1.5 parts of phenolic antioxidant and 0.5-1.5 parts of hindered amine light stabilizer. The automobile door trim is prepared by an injection forming method. The invention has the advantage of stable forming technology, the technological parameters are easy to adjust and control, and the door trim product has the advantages of stable quality and low density, thereby achieving the goal of lowering weight and cost of the product.
Description
technical field [0001] The invention belongs to the field of new automobile materials, in particular to an automobile door guard plate made of composite materials. Background technique [0002] Polymer materials for automobiles occupy an increasingly important position in my country's polymer production. The development and application of high-quality polymer composite materials for automobiles has become an important topic in the current automobile and polymer industries. At present, inorganic or organic nanomaterials have been widely used in the research field of polymer-based composite materials, which has changed the concept that inorganic fillers mainly play an incremental role, and it can improve various indicators of the comprehensive performance of materials at the same time. Since the 1990s, polymer / clay nanocomposites have attracted widespread attention due to their excellent properties. [0003] At present, the materials used to produce automobile door guards, t...
