The invention discloses a preparation method of noise reduction and sound absorption fibers for an automobile. The noise reduction and sound absorption fibers for the automobile are prepared through a mixing device; the mixing device comprises a base, a water washing mechanism, a filtering mechanism, a driving motor and a stirring mechanism; and the stirring mechanism comprises a heating barrel, a barrel cover hinged to the top of the heating barrel, a rotating rod rotationally connected to the bottom of the heating barrel, positioning rings welded to the outer wall of one side of the rotating rod and distributed at equal intervals, stirring rods welded to the outer walls of the four sides of the positioning rings, an inclined plate welded to the bottom of the inner wall of one side of the heating barrel, and a discharge port formed in the bottoms of the heating barrel and the inclined plate. According to the preparation method of the noise reduction and sound absorption fibers for the automobile provided by the invention, multiple sliding grooves are formed in the inner wall of a filtering box and can be connected with a filtering plate, and raw materials can be filtered for multiple times, so that the quality of the raw materials is improved; and a handle can be pulled to take out the filtering plate for replacement, so that the filtering effect can be greatly improved, the filtering plate can be conveniently replaced, the practicability of the device can be improved to a certain extent, and the product quality is improved.
Description
technical field [0001] The invention relates to the technical field of sound-absorbing and sound-absorbing fibers for automobiles, in particular to a method for preparing sound-absorbing and sound-absorbing fibers for automobiles. Background technique [0002] Fiber refers to a substance consisting of continuous or discontinuous filaments. In animals and plants, fibers play an important role in maintaining tissues. Fibers are widely used and can be woven into thin threads, thread ends and hemp ropes. They can also be woven into fiber layers when making paper or felt; they are also commonly used to make other materials. And together with other materials to form composite materials, natural fibers exist in nature, and fibers can be obtained directly. According to their sources, they can be divided into three types: plant fibers, animal fibers and mineral fibers. In the automotive field, sound-absorbing fibers need to be used. [0003] The existing sound-absorbing fiber produc...
