Abstract

The invention provides a low-odor, low-emission and flame-retardant composite material and a preparation method thereof, and relates to the technical field of high polymer materials. The low-odor, low-emission and flame-retardant composite material provided by the invention is prepared from the following raw materials: modified polypropylene, an inorganic filler, glass beads, modified sepiolite, amodified tourmaline powder, a lubricant, zinc stearate, a coupling crosslinking agent and an antioxidant. The polypropylene composite disclosed by the invention is a low-emission organic (benzenes and aldehydes and like eight substances are low) material with good flame retardance and low odor; the material provided by the invention can be extensively applied to the automobile industry, especially the exterior and interior decoration materials of the new energy automobile, is free from environment pollution, green and environment-friendly, and capable of guaranteeing the human health of the user.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a low-odor, low-emission, flame-retardant polypropylene composite material and a preparation method thereof. Background technique [0002] With the rapid development of polypropylene (PP) material modification technology, it is widely used in the automobile industry, especially for interior and exterior decoration materials of automobiles. With the development of the automobile industry, people put forward higher requirements for automobiles: light weight, energy saving, beautiful appearance, safety, environmental protection, etc. However, due to the fact that polypropylene materials release volatile substances containing some unpleasant odors or harmful to human health to varying degrees, they are increasingly questioned by consumers. The state is paying more and more attention to this. [0003] On March 1, 2012, GB / T27630-2011 "Guidelines for Evaluation of Air Quali...
