Abstract

The invention discloses a flame-retardant composite material for the interior decoration of a new energy automobile and a preparation method of the flame-retardant composite material. The composite material comprises the following components in parts by weight: 30-45 parts of polypropylene resin, 1-5 parts of nickel powder, 12-15 parts of sodium silicate, 8-14 parts of steel fibers, 0.03-0.05 partof a toughening agent, 10-18 parts of ethylene glycol, 5-8 parts of terephthalic acid and 1-3 parts of inorganic phosphinate. Uniformly mixing sodium silicate, steel fibers, a toughening agent, ethylene glycol and terephthalic acid to obtain a first mixture; and adding polypropylene resin and nickel powder into a main feeding port of a double-screw extruder, adding the first mixture into a firstside feeding port, adding inorganic phosphinate into a second side feeding port, extruding, and cooling. The composite material disclosed by the invention has good ductility, good heat resistance andhigh melting point, the melting point of the composite material is further raised due to the addition of the steel fibers, the safety is improved when the composite material is applied to a new energyautomobile, the preparation method is simple, and the industrialization is easy.

Description

technical field [0001] The invention relates to the technical field of preparation of flame retardant materials, in particular to a flame retardant composite material for interior decoration of new energy vehicles and a preparation method thereof. Background technique [0002] Petroleum is one of the most important disposable energy sources in the world. With the development of the economy, people's demand for petroleum is increasing day by day, and the supply is in short supply. People begin to develop clean and renewable energy. With the advancement of technology, the energy sources of automobiles are becoming more and more diversified. It will be the development trend of new energy vehicles in the future to replace petroleum with electric energy as the driving energy. [0003] At present, the new energy vehicles on the market are mainly hybrid and pure electric vehicles, and these vehicles need to frequently charge the vehicle power supply and power battery. Regardless o...
