Abstract

The invention discloses a halogen-free flame-retardant polypropylene material for automotive interiors, which is prepared from the following raw materials in parts by weight: 40-70 parts of polypropylene, 10-20 parts of coated ammonium polyphosphate, 5-10 parts of piperazine pyrophosphate, 5-10 parts of a synergistic flame retardant, 0.5-2 parts of a compatilizer, 0-10 parts of an inorganic filler, 10-20 parts of a flexibilizer, 0.2-1 part of a deodorant and 0.3-1.5 parts of a stabilizer, wherein the coated ammonium polyphosphate is prepared by carrying out surface coating modification on high-polymer ammonium polyphosphate by using melamine formaldehyde and epoxy resin. The polypropylene material provided by the invention not only meets the requirement for flame retardant property, but also has the characteristics of excellent rigid-tough balance, precipitation resistance and low odor, is suitable for being applied to automobile industry interiors, and is particularly suitable for passenger car interiors.

Description

technical field [0001] The invention relates to the technical field of polymer material modification, in particular to a halogen-free flame-retardant polypropylene material for automobile interior decoration and a preparation method thereof. Background technique [0002] With the improvement of people's awareness of safety and environmental protection, especially the frequent occurrence of bus fire accidents in recent years, the society has paid great attention to the combustion safety performance of bus materials. The latest national standard "GB38262-2019 Combustion Characteristics of Passenger Car Interior Materials" will be officially implemented on July 1, 2020. The new national standard puts forward stricter requirements for horizontal combustion, vertical combustion, oxygen index, and smoke density. In addition, people have higher and higher requirements for the air quality in the car, and major domestic and foreign automobile manufacturers have made clear requirement...
