Problems solved by technology

[0004] However, different from the relatively simple components and synthesis process of halogen-based flame retardants, the phosphorus-nitrogen intumescent halogen-free flame retardant IFR often involves the synthesis and use of multiple organic compounds, which will inevitably affect the performance of flame retardants. Some environmental indicators such as odor and total carbon (TVOC) of flammable materials have negative impacts, especially when used as automotive interior parts, and related situations have not attracted attention in the current research on halogen-free flame retardant

Abstract

The invention discloses a highly environmental-friendly flame retardant reinforced PC / ABS blending material and a preparation method thereof. The flame retardant reinforced PC / ABS blending material comprises the following raw materials in percentage by weight: 50-80% of PC, 10-30% of ABS, 5-15% of flame retardant and 3-15% of carbon fiber. The carbon fiber is subjected to surface activating treatment. The flame retardant reinforced PC / ABS blending material obtained through the technical scheme of the invention has the many advantages, such as high strength, high flame retardance and high environmental-friendly property. By addition of the carbon fiber subjected to surface activation, stretching and bending performance of the blending material can be enhanced, and various organic volatile matter constituents in the PC / ABS can be adsorbed effectively by lots of micropores on the surface of the carbon fiber, so that multiple environmental indexes, such as material odor and TVOC (Total Volatile Organic Compounds), are improved, more importantly, the promotion of environmental performance is not at the cost of sacrificing the flame retardance of material, on the contrary, the flame retardance of the blending material is also promoted, the combustion time of the blending material away from the fire becomes shorter, and the self-extinguish ability of the blending material becomes better.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a highly environmentally friendly flame-retardant reinforced polycarbonate (PC) / acrylonitrile-butadiene-styrene (ABS) blend material and a preparation method thereof. Background technique [0002] On the one hand, the PC / ABS blend material has the high mechanical properties, impact resistance, excellent heat resistance and chemical resistance of PC materials, and the addition of ABS can make up for the processing problems caused by the high melt viscosity of PC. , so that the processing fluidity of the material is greatly improved, and there is good compatibility between the two, so it is widely used in the fields of automobile interior and exterior decoration, electric tools, household appliances and lighting equipment. [0003] With the continuous development of the modern automobile industry, automobiles have become an indispensable and important tool in ...
