[0023] Such as figure 1 As shown, the preparation method of the hollow fiber damping material with coupling airbag adjustment provided by the embodiment of the present invention includes the following steps:
[0024] S101: According to the concentration of the blended polymer being 22%, the blending mass ratio is 40:60, respectively weigh a certain quality of hydrogenated nitrile butadiene rubber raw materials (acrylonitrile content reaches 36%) and polyvinyl chloride raw materials, and measure a certain amount. The volume of organic solvent N'-N'dimethylacetamide is heated and stirred in a constant temperature water bath with the help of a container, the temperature is controlled at 50°C, and it is continuously heated and stirred for 8 hours to dissolve it, and the hollow spinning casting solution is prepared;
[0025] S102: Add the completely dissolved casting solution into the stirring tank of the spinning machine and stir until the material is completely dissolved, then st...
Embodiment 1
[0031] The preparation method of the hollow fiber damping material provided by the embodiment of the present invention with coupling-type airbag regulation includes the following steps:
[0032] Step 1, according to the concentration of the blended polymer is 22%, the blending mass ratio is 40:60, respectively weigh a certain quality of hydrogenated nitrile butadiene rubber raw material (acrylonitrile content reaches 36%) and polyvinyl chloride raw material, and measure A certain volume of organic solvent N'-N'dimethylacetamide is heated and stirred in a constant temperature water bath with the help of a container, and the temperature is controlled at 50°C. It is continuously heated and stirred for 8 hours to dissolve it, and is prepared into a hollow spinning casting solution;
[0033] Step 2: Add the completely dissolved casting solution into the stirring tank of the spinning machine for stirring, stir until the material is completely dissolved, and stand at a constant temper...
