Abstract
The invention discloses a heat-resistant glass fiber-reinforced PC / ABC composite material and a preparation method thereof. The heat-resistant glass fiber-reinforced PC / ABC composite material comprises the following components in percentage by weight: PC resin 5-80, ABS resin 5-80, glass fibers 10-40, compatilizer 3-15, heat-resistant stabilizer 0.1-2 and other assistants 0.2-4. Concretely, the method comprises the following steps: weighing all materials except the glass fibers; mixing the materials in a high-speed mixer for 3 to 5 minutes; and adding the mixed materials into a double-screw extruder, wherein the glass fiber is added from a first exhaust hole, the temperatures front a feed inlet to a mold head is 200 to 220 DEG C, 220 to 250 DEG C, 240 to 260 DEG C, 240 to 270 DEG C and 240 to 260 DEG C and the rotating speed of the main machine is 20 to 50Hz; and making a sample by using a plastic injection machine. The composite material is heat resistant, can be stored at high temperature for a long time and has stable performance, impact resistance and high processability.
Description
technical field [0001] The invention relates to a PC / ABS composite material, in particular to a heat-resistant glass fiber reinforced PC / ABS composite material and a preparation method thereof, belonging to the field of polymer composite materials. Background technique [0002] Glass fiber reinforced PC / ABS alloy can effectively improve the mechanical properties of composite materials, and can also effectively increase its heat resistance temperature, expanding the application field, not only can be used as automotive decorative parts, but also can be used as automotive structural parts. [0003] Due to the good ductility of glass fiber reinforced PC / ABS, the energy absorption during impact is 50% higher than that of traditional instrument panel materials, bringing more safety to passengers, and at the same time, it has good processing performance , is the preferred material for many companies to produce dashboards for cars. However, as a material for an instrument panel, i...
