Abstract

The invention relates to the field of automotive interior materials, and discloses a lightweight extinction plastic master batch for an automotive interior and a preparation method of the master batch. The preparation method comprises the following process: (1) adding sodium phosphate, a soluble polymer, nano mica sheets and a soluble calcium salt into water to prepare a precursor liquid; (2) performing a microwave hydrothermal reaction on the precursor liquid to form calcium phosphate on the nano mica sheets, and performing assembling to form composite loose particles; and (3) mixing polypropylene carrier resin, the composite loose particles, an elastomer toughening agent, an inorganic nano filler and an auxiliary agent, and performing extrusion granulation to obtain the lightweight extinction plastic master batch for the automotive interior. Compared with a traditional plastic master batch for an automotive interior, the lightweight extinction plastic master batch prepared by the invention has the advantages of good surface extinction property, high toughness, good fluidity, lower costs and a high degree of lightness; and the preparation method has a simple manufacturing procedure and low comprehensive costs, and is especially suitable for the field of the automotive interior.

Description

technical field [0001] The invention relates to the field of automobile interior decoration materials, and discloses a lightweight matte plastic masterbatch for automobile interior decoration and a preparation method. Background technique [0002] In automobile manufacturing materials, the application of engineering plastics in automobile interior parts is mainly aimed at safety, environmental protection and comfort. For safety, environmental protection and comfort considerations, interior materials are generally required to have the following characteristics: good strength and stiffness, able to withstand a certain impact load; good dimensional stability, especially high temperature stability; good UV resistance and weather resistance to ensure a service life of more than 10 years; good solvent resistance; low odor; matte finish. [0003] In automotive interior materials, low odor and matte properties are especially important for interior materials on the premise of satisf...
