preparation example Construction

[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...

Abstract

The invention belongs to the technical field of hollow fiber damping materials, and discloses a preparation method of a hollow fiber damping material adjusted by a joint type air bag, comprising: preparing a hollow spinning casting liquid; adding the completely dissolved casting liquid to the spinning Stir in the stirring tank of the machine; make the casting liquid spray out from the spinneret of the spinning machine, and spin to obtain the hollow fiber of hydrogenated nitrile rubber; The two halves of the buckle mold clamp the hollow fiber into a long and short joint type, and then place it in clean water for soaking and phase separation; place the hollow fiber with a complete phase transition, take it out and place it to dry at room temperature. It is hollow fiber damping material. The invention improves the adjustment method of airbag damping of the hollow fiber damping material and has important application value, and solves the problem that the airbag of the hollow fiber damping material whose section does not change along the axial dimension is too single.

Description

technical field [0001] The invention belongs to the technical field of hollow fiber damping materials, and in particular relates to a preparation method of a hollow fiber damping material with coupling-type air bag adjustment. Background technique [0002] With the development of science and technology, the demand for damping materials for vibration and noise reduction is becoming more and more stringent, and there is little research on multi-component damping composite damping materials. Therefore, it is necessary to develop lightweight and high-performance polymer damping materials to satisfy people Demand has become a research hotspot in the field of environmental functional materials; the rational use of damping materials can not only achieve the purpose of reducing vibration and noise of mechanical equipment and partitions, prevent noise from polluting the environment, ensure people's quality of life, but also prolong the service life of equipment. The service life ensu...
