Polypropylene composite flame-retardant material for vehicle interior decoration as well as preparation method and application thereof

Abstract

The invention belongs to the technical field of flame retardance, in particular to a polypropylene composite flame-retardant material for vehicle interiors. Based on a condition that the total mass ofthe polypropylene composite flame-retardant material is 100%, the composite flame-retardant material comprises the following raw material components in percentage by mass: 40-90% of polypropylene, 2-15 of a brominated flame retardant, 1-5% of antimonous oxide, 0-10% of a flexibilizer, 0-40% of an inorganic filler, 0.2-10% of a smoke suppressant, 0.1-0.5% of an anti-dripping agent, 0.2-2% of a scratch-resistant agent, 0.2-2% of an antioxidant, 0.2-2% of a light stabilizer and other additives. The polypropylene composite flame-retardant material for vehicle interior decoration has good tensilestrength, bending property, impact strength and other mechanical properties, and also has the properties of high limit oxygen index, low smoke density grade, low odor, low total carbon, light resistance and the like.

Description

Technical field [0001] The invention belongs to the field of flame-retardant technology, and in particular relates to a polypropylene composite flame-retardant material used for vehicle interior decoration and a preparation method and application thereof. Background technique [0002] In recent years, fires caused by the spontaneous combustion of buses have been reported frequently, causing great harm to people's lives and property, and arousing high attention from the society on the combustion safety performance of passenger car interior materials. There are many types and quantities of passenger car interior materials. In the event of a fire, it is easy to produce molten drips, accompanied by a large amount of dense smoke, which will cause oxygen deficiency and suffocation of passengers in a short time. Therefore, automotive interior materials not only require a certain degree of flame retardancy, but also put forward higher requirements for the degree of smoke after combustion...
