Preparation method of light soundproof door composite board
The invention relates to a preparation method of a light soundproof door composite board, and belongs to the technical field of board preparation. The technical problems that an existing soundproof door is large in weight, poor in effect and high in production cost are solved. The preparation method comprises the following steps that S1, a soundproof door panel is prepared; S2, soundproof door keels are prepared; and S3, foamed aluminum is foamed to prepare the soundproof door composite board. Coal gangue, coal ash and other wastes are recycled, the prepared soundproof door is light in weight, large in density and high in strength, an inner cavity of the soundproof door is filled with the foamed aluminum material in a foaming mode, the soundproof effect is achieved, meanwhile, the bonding performance between the soundproof door panel and the keels is improved, and the service life of the soundproof door is prolonged.
本发明涉及一种轻质隔声门复合板材的制备方法，属于板材制备技术领域，解决现有隔声门重量大、效果差、生产成本高的技术问题，本发明包括以下步骤：S1、隔声门面板制备；S2、隔声门龙骨制备；S3、泡沫铝发泡，制得隔声门复合板材。本发明将煤矸石、粉煤灰等废物再利用，制备的隔声门质量轻、密度大、强度高，而且采用泡沫铝材料发泡填充隔声门内腔，起到隔声作用的同时，增加了隔声门面板和龙骨之间的结合性，有利于提高隔声门的使用寿命。
