Mineral wool acoustic board and preparation method thereof
The invention discloses a mineral wool acoustical board and a preparation method thereof. The mineral wool acoustical board is prepared from the following components in parts by weight: 100 to 150 parts of mineral wool fibers; 20 to 28 parts of binding material 1; 5 to 10 parts of binding material starch 2; 1.5 to 2.5 parts of flocculating agent 1; 1 to 3 parts of flocculating agent 2; and 0.4 to2.0 parts of emulsified paraffin. The method includes the steps of: weighing the binding material 1, uniformly mixing the binding material 1 to prepare binding slurry for later use; fully stirring theflocculant 1 diluted by water, the mineral wool fibers, the binding material starch 2, the flocculating agent 2 and the emulsified paraffin with water in a stirrer to obtain mixed slurry; molding anddrying the mixed slurry to obtain a semi-finished mineral wool board wet board; spraying the binding slurry on the surface of the mineral wool board wet board, and carrying out post-treatment to obtain a finished product. According to the mineral wool acoustic board, phosphogypsum is used as the binding material, so that the application range of the phosphogypsum is expanded, stacking of harmfulsubstances is reduced, and the effect of recycling resources is achieved.
本发明公开了一种矿棉吸音板及其制备方法，所述矿棉吸音板配方组成按重量计包含矿棉纤维100‑150份、粘结料1 20‑28份、粘结料2淀粉5‑10份、絮凝剂1 1.5‑2.5份、絮凝剂2 1‑3份和乳化石蜡0.4‑2.0份。所述方法包括，称取粘结料，将粘结料1混合均匀后制成粘结料浆待用，将经水稀释后的絮凝剂1、矿棉纤维、粘结料2淀粉、絮凝剂2和乳化石蜡在搅拌机中与水充分搅拌后得到混合料浆，之后将混合料浆成型，干燥得到半成品矿棉板湿板，将粘结料浆喷涂在矿棉板湿板表面，通过后处理得到成品。本发明所述的矿棉吸音板使用磷石膏作为粘结料扩大了磷石膏的应用范围，降低了有害物质的堆放，起到了资源循环利用的作用。
