Abstract

The invention discloses a polypropylene composite material as well as a preparation method and application thereof. The polypropylene composite material is prepared from the following raw materials: polypropylene, POE, a nucleating agent, a mineral filler, a coupling agent, a free radical capturing agent, a thermal oxidation resistant stabilizer, an extracting agent, a scratch resistant agent anda lubricating agent, and the melt flow rate of the POE under the test conditions of 190 DEG C and 2.16 kg is 0.5 g / 10 min to 5 g / 10 min. According to the invention, polypropylene is used as a matrix,POE with low melting performance is added, and the mineral filler, the nucleating agent and the extractant are scientifically matched so that the impact performance of the polypropylene composite material is improved, the composite material has good heat resistance and low odor, and the high-quality requirement of the seamless airbag instrument board is met.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a polypropylene composite material and its preparation method and application. Background technique [0002] The materials industry is the backbone of the automotive industry. With the continuous development and progress of society, the sales of automobiles are increasing year by year, and the requirements for materials of automobiles are getting higher and higher. [0003] As the most important interior part of a car, the instrument panel is a thin-walled, large-area, and complex-shaped auto part with many holes for installing instrument components. Interior parts that combine performance and decoration. Before the instrument panel is delivered for use, it is necessary to conduct high and low temperature airbag point explosion experiments to ensure that the airbag pops up safely and effectively. Therefore, there are extremely high requirements for the low...
