| titleOfInvention | Mineral wool acoustic board and preparation method thereof |
| abstract | The invention discloses a mineral wool sound-absorbing board and a preparation method thereof, wherein the formula of the mineral wool sound-absorbing board comprises, by weight, 100-150 parts of mineral wool fibers, 120-28 parts of a binding material, 5-10 parts of a binding material 2 starch, 11.5-2.5 parts of a flocculating agent, 21-3 parts of a flocculating agent and 0.4-2.0 parts of emulsified paraffin. The preparation method comprises the steps of weighing the bonding material 1, uniformly mixing and activating the bonding material 1, grinding the bonding material 1, fully stirring the ground bonding material, the flocculant 1 diluted by water, the mineral wool fiber, the starch of the bonding material 2, the flocculant 2 and the emulsified paraffin with water in a stirrer to obtain mixed slurry, forming the mixed slurry, drying to obtain a semi-finished product, and carrying out post-treatment on the semi-finished product to obtain a finished product. The mineral wool sound-absorbing board uses the phosphogypsum as the binding material, so that the application range of the phosphogypsum is expanded, the stacking of harmful substances is reduced, and the effect of resource recycling is achieved. |
