The invention relates to a production technology of a rock
wool board with the functions of sound absorption and
noise reduction. The production technology includes the following steps that corn stalk fibers, sugarcane fibers and
chitosan are stirred and smashed; after anaerobic
fermentation,
filtration and
drying are conducted; after
polyvinyl alcohol,
calcium oxide and
mugwort leaf oil are uniformly mixed, a circuit is closed; two obtained mixtures are mixed and compressed; after
activated carbon is added and
reflux condensation is conducted, hydroxyl
acrylic resin and thermosetting phenolic resin are added, smashed and grinded; after
ultrasonic dispersion, a mixture is taken out, silica sand is added, and dolerite,
dolomite, hydroxyapatite,
perlite, expansile
graphite, phenolic resin,
moisture repellent and a
coupling agent are added and mixed; after being fused at a high temperature, a mixture is subjected to centrifugal rotation and wafted to a
wool collecting
machine; a
pendulum method is adopted, the mixture is folded to be of a rock
wool structure, and a binding agent is sprayed; wool filaments are solidified,
cut and subjected to edge
cutting, and the rock wool board is obtained. By the adoption of the production technology of the rock wool board with the functions of sound absorption and
noise reduction, the produced rock wool board has the functions of sound absorption and
noise reduction and can effectively reduce the disturbance of
external noise.
