Abstract

The invention discloses anti-impact modified polycarbonate plastics for automotive interior parts and a preparation method thereof. The polycarbonate plastics comprise the following ingredients in parts by weight: 100 parts of polycarbonate, 10-20 parts of calcium carbonate nanoparticles, 1-5 parts of coupling agent, 15-40 parts of anti-impact modifier and 10-35 parts of filler modifier. The preparation method comprises the following steps of: weighing raw materials according to a proportioning ratio, mixing the raw materials to be uniform, then, carrying out melting compounding, and carrying out extrusion pelleting, thereby obtaining the polycarbonate plastics. The anti-impact modified polycarbonate plastics for the automotive interior parts, disclosed by the invention, have the appearance and performance of a rubber body, have higher pulling strength, bending strength, bending modulus and gap impact strength and can be easily processed into automotive interior parts of various shapes through an injection molding process, such as a glove box inner cover plate, a glove box bucket, a vice instrument panel body, a storage box liner and a panel storage box.

Description

technical field [0001] The invention relates to a plastic and a preparation method thereof, in particular to an impact-resistant modified polycarbonate plastic for automotive interior parts and a preparation method thereof. Background technique [0002] Polycarbonate plastics, referred to as PC plastics, are high molecular polymers containing carbonate groups in their molecular chains. According to the structure of ester groups, they can be divided into aliphatic, aromatic, aliphatic-aromatic and other types. Among them, the low mechanical properties of aliphatic and aliphatic-aromatic polycarbonates limit their application in engineering plastics. At present, only aromatic polycarbonate has been industrialized. Due to the special structure of polycarbonate, it has become the fastest-growing general-purpose engineering plastic among the five major engineering plastics. [0003] However, the impact resistance of PC plastic products is not good, which greatly limits the appl...
