Easily poached and dyed PC/ABS composite material and preparation method thereof

Abstract

The invention discloses an easily poached and dyed PC / ABS composite material and a preparation method thereof. The composite material is prepared from special PC resin, ABS resin, a flexibilizer, a flow improver, an antistatic agent and titanium dioxide. The added flow improver improves the flowing property of a material greatly and reduces the processing temperature of the material, so that the material which poached is easily softened. By adding the flexibilizer, the problem that the toughness is poor as the flow improver is added is solved. By adding the anti-static agent to improve the surface polarity of the material, the material interacts with toner more easily, so that the material is dyed more easily; titanium and aluminum in the titanium oxide can be cheated with the antistatic agent, the PC resin and the toner, so that the coloring ability of the material is improved. The material is good in flowing property and high in surface polarity and has the chelating action. When thematerial is poached and dyed, the toner enters a resin matrix more easily. Finally, the color fastness is improved greatly while the material has excellent flowing property and toughness, and the appearance problem in an injection molding process is avoided.

Description

technical field [0001] The invention relates to a PC / ABS composite material and a preparation method thereof, in particular to a PC / ABS composite material which is easy to be boiled and dyed and a preparation method thereof, and belongs to the technical field of polymer composite materials and processing thereof. Background technique [0002] PC (polycarbonate) resin is a thermoplastic engineering plastic with excellent physical and mechanical properties, especially its excellent transparency and flame retardancy, so it has a wide range of applications, especially in the field of appearance products , but due to the high rigidity of the polycarbonate molecular chain, high melt viscosity, and high molding temperature, it is difficult to dye it at a lower temperature. In view of the above shortcomings, for the modification of PC products, ABS is usually added to the PC resin to improve the processing fluidity of the overall composite material, but its effect is extremely limit...

AI Technical Summary

Problems solved by technology

[0002] PC (polycarbonate) resin is a thermoplastic engineering plastic with excellent physical and mechanical properties, especially its excellent transparency and flame retardancy, so it has a wide range of applications, especially in the field of appearance products , but due to the high rigidity of the polycarbonate molecular chain, high melt viscosity and high molding temperature, it is difficult to dye it at a lower temperature

In view of the above shortcomings, for the modification of PC products, ABS is usually added to the PC resin to improve the processing fluidity of the overall composite material, but its effect is extremely limited. At the same time, as the proportion of ABS resin increases, the toughness of the composite material will decrease. Decrease, it is necessary to increase the overall toughness of the composite material by adding a toughening agent, but the toughening agent has a negative effect on the fluidity of the material

In the existing ordinary PC or PC / ABS products, due to the product structure and material characteristics, it is inevitable that there will be color difference or other appearance problems in color at the position of the welding line or some special structures of the above products
