The invention discloses a diatomite environment-friendly acoustical board, relates to the technical field of acoustical boards, and mainly aims to solve the problem that most of existing acoustical boards adopt gypsum boards and are poor in water resistance. The acoustical board comprises the following raw materials: resin, diatomite, polypropylene fibers, bamboo charcoal fibers, glass fibers, attapulgite clay, modified mica powder, coarse stone powder, sodium alginate, modified fly ash, a polyolefin elastomer, water, an ethylene-vinyl acetate copolymer, lignocellulose, chitosan, a rare earthcatalyst, a water repellent, a flocculant, a binder, a flame retardant and a lubricant. The diatomite is added, so that the acoustic board has good extensibility, high impact strength, tensile strength, tearing strength, light weight, good internal grinding performance, good high-pressure strength and other excellent effects, the resin and the polyolefin elastomer are added, so that good elasticity is achieved, the sound absorption capacity of the acoustic board can be improved, and meanwhile toughness is enhanced.
本发明公开了一种硅藻土环保吸音板，涉及吸音板技术领域，主要为了解决现有吸音板大多采用石膏板耐水性差的问题；包括以下原料：树脂、硅藻土、聚丙烯纤维、竹炭纤维、玻璃纤维、凹凸棒石粘土、改性云母粉、粗石粉、海藻酸钠、改性粉煤灰、聚烯烃弹性体、水、乙烯‑醋酸乙烯共聚物、木质纤维素、壳聚糖、稀土催化剂、憎水剂、絮凝剂、粘结剂、阻燃剂、润滑剂，本申请的吸音板通过加入硅藻土，从而具有较好的延伸性，有较高的冲击强度、拉伸强度、撕裂强度、质轻软内磨性好、高压强度好等方面优质作用，加入树脂以及聚烯烃弹性体，具有好的弹性，能够提高吸音板的吸音能力，同时其也增强了韧性。
