The invention discloses a flame-retarding PC (Polycarbonate) / ABS (Acrylonitrile Butadiene Styrene) blend material for automobile interior trimmings. The flame-retarding PC / ABS blend material comprises the following formula in a percentage by weight: 60-80% of PC, 10-30% of ABS, 5-15% of halogen-free flame retardant and 3-10% of compound auxiliary. The halogen-free flame retardant in the system is used in combination with the compound auxiliary which consists of magnesium hydroxide, zinc borate and molecular sieve activated powder so as to obtain an excellent effect. The halogen-free flame retardant has a great flame-retarding effect and generates a small quantity of smoke. The compound auxiliary does not contain volatile organic substances and has remarkable heat and smoke absorbing effects after combustion. Due to the adoption of the technical scheme, the flame-retarding performance indexes, such as oxygen indexes and combustion smoke generating quantity, of the flame-retarding PC / ABS blend material for the automobile interior trimmings are obviously improved, the main VOC(Volatile Organic Compounds)index of the blend material is obviously reduced, high environment-friendly performance is represented, and meanwhile, the requirements of the existing automobile interior trimmings on the combustion and VOC performances of the material can be simultaneously met.
Description
technical field [0001] The invention relates to a flame-retardant polycarbonate (PC) / acrylonitrile-butadiene-styrene (ABS) blend material, in particular to a flame-retardant PC / ABS blend material for automotive interior parts and a preparation method thereof. Background technique [0002] PC / ABS blended materials are widely used in automotive trim, industrial electronics, household appliances and other fields because of the excellent characteristics of both PC and ABS. Among them, PC endows the blended materials with good chemical resistance and excellent impact resistance. The addition of ABS can reduce the viscosity of PC melt, significantly improve the fluidity of melt, and improve the processing performance of blended materials. [0003] With the development of the modern automobile industry, the application proportion of plastics in automobiles is getting higher and higher, especially the interior parts that have the most contact with drivers and passengers.
