Preparation method of aluminum oxide sound insulation plate
The invention discloses a preparation method of an aluminum oxide sound insulation board, which comprises the following steps: feeding limestone clay into a pulverizer, pulverizing to prepare limestone clay powder, adding an adhesive into a container containing the limestone clay powder, fully stirring for 10-20 minutes, then adding water, adding the adhesive again, and stirring for the second time to obtain a mixture I; aluminum oxide particles with a certain particle size are added in the preparation process of the sound insulation board, and epoxy resin is adopted for bonding and mixing, so that the effect of circulating sound insulation can be achieved, all the raw materials are mixed more tightly, the sealing performance of the sound insulation board is greatly improved, and the service life of the sound insulation board is prolonged. The structural strength of the sound insulation board is guaranteed, the sound absorption coefficient of the sound insulation board can be improved, a good sound insulation effect is obtained, meanwhile, the water repellent agent and the flame retardant are added, and therefore the sound insulation board further has water absorption and flame retardant performance, and actual use is facilitated.
本发明公开了一种氧化铝的隔音板制备方法，包括以下步骤：将石灰石粘土送入粉碎机中进行粉碎，制成石灰石粘土粉，并向盛有石灰石粘土粉的容器中加入黏合剂，充分搅拌10‑20min，然后加入水，并再次加入黏合剂，进行二次搅拌，得到混合物一，本发明通过在隔音板的制备工序中加入具有一定粒径的氧化铝颗粒，并采用环氧树脂进行粘接混合，不仅能够达到循环隔音的效果，而且使得各项原料之间的混合更加的紧密，极大的提高了隔音板的密封性能，在保证隔音板结构强度的同时能够提高隔音板的吸声系数，获得较好隔音效果，同时还加入了抗水剂与阻燃剂，从而使得隔音板还具有吸水与阻燃性能，有利于实际的使用。
