Embodiment 1
[0034] A production process of rock wool boards with sound-absorbing and noise-reducing functions, the steps are as follows: (1) Add ethanol to corn stalk fibers and sugarcane fibers to soak for 2 hours, then take them out, and put the mixture into hot water at 65°C After soaking for 3 hours, chitosan and polypropylene fibers were added and stirred at 55°C for 5 hours, and then the mixture was put into a crushing device for crushing; , chitosan, polypropylene fiber mass ratio is 5:2:1:2;
[0035] (2) Put the mixture into the anaerobic fermentation tank, and make the mixture undergo anaerobic fermentation for 6 days, then filter and dry;
[0036] (3) After mixing 3 parts of polyvinyl alcohol, 3 parts of calcium oxide, and 13 parts of mugwort oil, 24 parts of distilled water were added, and the mixture was stirred at 26°C, and then energized for 1.5 hours;
[0037] (4) Mix step (2) and step (3), put the mixture into a pressure device, and let the mixture react at 70MPa for 14 m...
Embodiment 2
[0055] A production process of rock wool boards with sound-absorbing and noise-reducing functions, the steps are as follows: (1) Add ethanol to corn stalk fibers and sugarcane fibers and soak them for 4 hours, then take them out, and put the mixture into hot water at 60°C After soaking for 5 hours, chitosan and polypropylene fiber were added and stirred at 50°C for 7 hours, and then the mixture was put into a crushing device for crushing; in the step (1), corn stalk fiber, sugarcane fiber , chitosan, polypropylene fiber mass ratio is 5:2:1:2;
