摘要： The present invention relates to a sound-insulation shock-absorbing heat-resistant ABS resin composition for automotive interiors and a preparing method thereof. The resin composition comprises: 100 parts of ABS resin, 5-30 parts of heat-resisting agent, 5-20 parts of sound-insulation shock-absorbing polymer, 1-5 parts of hollow glass microspheres, 0.3-1.0 part of light stabilizer and 0.5-2.0 parts of auxiliary. The preparing method comprises the following steps: mixing the raw materials in a high-speed mixer, sending the mixture into a twin screw extruder via a metering device, melting and compounding the material under the delivering, shearing and mixing by screws; and performing extrusion, drawing, cooling and granulating. The method is simple and feasible; and the prepared resin composition has excellent sound-insulation and shock-absorbing effects and favorable mechanical properties, and is able to be applied in the field of automotive interiors.
