Acoustic material manufacturing method

Abstract

The invention provides an acoustic material manufacturing method, and solves such technical problems as no corresponding manufacturing method for a traditional acoustic material, need of manufacturing by dint of experiences and complicated manufacturing. The acoustic material manufacturing method comprises the following steps: (a) the following raw materials are weighed in parts by weight: 14-20 parts of cotton fibers, 6-7 parts of glass fibers, 10-14 parts of aluminum fibers, 8-12 parts of gypsum powder, 6-9 parts of asbestos powder, 3-10 parts of wood fibers, 2-6 parts of nanocarbon, 3-5 parts of magnesium oxide, and 1-3 parts of antiaging agent; (b) the raw materials are poured in a stirring machine to prepare a mixture; the stirring time is 5-15 min; and the stirring speed is 150-350 r / min; (c) the mixture is hot pressed as a strip-shaped plate; and the thickness of the strip-shaped plate is 60-120 mm; (d) protective liquid is sprayed to the surface of the strip-shaped plate through spraying equipment; a drying system is used for drying; the drying temperature is 40-60 DEG C; and the drying time is 15-25 min; and (e) the strip-shaped plate is cut as a needed shape to obtain an acoustic material. The acoustic material manufacturing method has the advantage of convenience in manufacturing.

Description

technical field [0001] The invention relates to a method for making a sound-absorbing material. Background technique [0002] Almost all the owners who live in the building have this kind of trouble. The various sounds from the neighbors are very disturbing, especially when falling asleep at night, it is easy to be woken up by the sudden sound, and it is difficult to fall back asleep after waking up. , This kind of voice is especially reflected in the days when there are major competitions like the European Cup. It is really not easy to interfere with others. You must let them stay in your own home. In fact, the solution is very simple, that is, to use professional sound-absorbing materials to achieve. Most of the sound-absorbing materials are loose and porous materials, such as slag wool, blankets, etc. The sound-absorbing mechanism is that the sound waves penetrate into the pores of the material, and the pores are mostly open holes that communicate with each other interna...

Problems solved by technology

[0004] Although the sound-absorbing material disclosed in this patent is non-toxic and harmless, there is no corresponding production method for the sound-absorbing material, which needs to be produced by experience, and the production is cumbersome. Therefore, it is necessary to design a production method for the sound-absorbing material
