Problems solved by technology

Among them, the plate-shaped structure is the simplest and the most widely used; it has a good effect on high-frequency sound absorption, but the low-frequency sound absorption effect is not good; the function is single, and it cannot decorate the environment except for the incomplete sound absorption effect. , cleaning and other functions; in terms of construction, a large number of keels are needed as a support, which affects the sound absorption effect to varying degrees; the production process of the sound-absorbing body is complicated and requires multiple processes to complete

Abstract

The invention relates to the preparation method of an acupuncturing 3D sound-absorbing body. The preparation method comprises the following steps:(a) weighting the first polyester staple fiber and fiber A respectively; (b) then entering into the cotton rolling equipment to carry out opening and mixing;(c) the fiber after processed by the cotton rolling equipment entering into a cotton mixing machine for further uniform mixing;(d) entering into the combing equipment and forming a fiber network after opening; (e) the fiber network entering into a stacking device for stacking;(f) forming cellucotton after first acupuncturing of the stacked fiber network; (g) placing a cotton blanket on the cellucotton, then carrying out the second acupuncturing to form into a acupuncturing cotton blanket;(h) cutting the acupuncturing cotton blanket into acupuncturing cotton blanket blocks by the cutting equipment; (i) enabling the acupuncturing cotton blanket blocks to enter into the heat setting equipment for heat setting; and(j) squeezing the acupuncturing cotton blanket blocks by a mould, so as to obtain the acupuncturing 3D sound-absorbing body. The 3D sound-absorbing body provided by the invention has the effects of sound absorption, noise reduction and decoration.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a method for preparing an acupuncture 3D sound-absorbing body. Background technique [0002] When the existing sound-absorbing body is prepared, it is inevitable to use a binder, thereby introducing harmful substances. The patent application with the application number 200910071340.2 discloses "a fiberboard with self-absorbing formaldehyde function and its manufacturing method". The scheme uses wood fiber, aldehyde adhesive and activated carbon as the main raw materials; Activated carbon is spread on the wood fiber, and the fiber board can be made by hot pressing. Because this kind of fiberboard adopts aldehyde adhesive in the preparation process, and the aldehyde adhesive itself will release harmful gas, which is not environmentally friendly; moreover, the adsorption effect of this kind of fiberboard is not very ideal. [0003] At present, the sound-absorbing bodies on the ma...
