Technical method of magnetic damping material for saloon car

Abstract

The invention aims to provide a technical method of a magnetic damping material for a saloon car. The method is characterized by comprising the following technical steps: (1), ensuring that the magnetic damping material comprises the following components in ratio: 20 to 25 percent of POE resin, 9 to 12 percent of tackifying resin, 10 to 14 percent of magnetic powder, 5 to 7 percent of rubber powder, and 45 to 60 percent of packing, mixing the raw materials in ratio and then heating the materials, and uniformly stirring the raw materials; (2), putting the heated and uniformly stirred raw materials in the step one into an extruder at a constant speed, so as to perform extrusion treatment, performing flatting forming treatment on the extruded materials through a flatting forming machine, andfinally cutting the materials into pieces through a rotary cutter, so as to form a finished product. The method has the advantages that mechanical vibration energy can be converted into thermal energyto be dissipated, a damping effect is achieved, meanwhile the material further has good mechanical property and corrosion resistance, heat is isolated through a physical method, material wastage is small, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of equipment for automobile materials, including the research and development and improvement of the processing and structure of automobile polymer materials, and in particular to a process method of magnetic damping materials for automobiles. Background technique [0002] With the improvement of living standards, the use of automotive products has gradually increased, especially in the aspect of automotive interior parts. At this stage, people's use of cars is not only for transportation, but has entered the stage of enjoyment. For automobiles The comfort level during use, especially in the heat insulation part of the car, requires damping materials for heat insulation, but the heat insulation materials used in the past basically absorb and conduct heat through the chemical properties of the damping materials to achieve heat insulation effects. However, the use of this kind of heat insulation material consumes a lot,...

[0002] With the improvement of living standards, the use of automotive products has gradually increased, especially in the aspect of automotive interior parts. At this stage, people's use of cars is not only for transportation, but has entered the stage of enjoyment. For automobiles The comfort level during use, especially in the heat insulation part of the car, requires damping materials for heat insulation, but the heat insulation materials used in the past basically absorb and conduct heat through the chemical properties of the damping materials to achieve heat insulation effects. However, the use of this kind of heat insulation material consumes a lot, the service life is not long, and the replacement cost is increased.
