The invention relates to a production process of rock wool board with sound-absorbing and noise-reducing functions. The steps are as follows: stirring and crushing corn stalk fiber, sugarcane fiber and chitosan; filtering and drying after anaerobic fermentation; polyvinyl alcohol, oxidized Calcium and mugwort oil are mixed and then electrified; the two mixtures are mixed and pressurized; hydroxyacrylic resin and thermosetting phenolic resin are added to pulverize and grind after adding activated carbon, condensed and refluxed; Dolomite, hydroxyapatite, perlite, expanded graphite, phenolic resin, water repellent, and coupling agent are mixed; after high-temperature melting, they are centrifugally rotated and blown to the cotton collector; they are folded into a rock wool structure by the pendulum method, and Spray the adhesive; after solidifying, cutting and trimming the cotton silk, the rock wool board is formed; the invention provides a production process of the rock wool board with sound-absorbing and noise-reducing functions, and the produced rock wool board has sound-absorbing The noise reduction function can effectively reduce the interference of external noise. |
