The invention discloses a preparation method of a light damping type bullet train/subway carriage bottom plate, which comprises the following steps of: assembling a wood veneer A, a wood veneer B, a non-woven fabric, a wood veneer A, a wood veneer B, a wood veneer A, a wood veneer C, a wood veneer B, a non-woven fabric, a wood veneer A, a wood veneer B and a wood veneer A in sequence from top to bottom, and then performing hot press molding, the wood-based composite base material is obtained; performing cold press molding with a bamboo charcoal plate to obtain a bamboo-based composite plate; and uniformly spraying a protective coating on the outmost layer of wood veneer A of the bamboo-based composite board to obtain the light shock-absorbing bullet train/subway carriage bottom plate. According to the manufacturing method, different wood veneers, non-woven fabrics and bamboo charcoal plates are compounded according to a certain assembly sequence through a method of combining hot pressing and cold pressing, the composite board meeting the technical specification requirements is manufactured, and the composite board has the advantages of being good in damping shock absorption performance, light in weight and the like and has the functions of flame retardance, formaldehyde removal, weather resistance and the like at the same time.
本发明公开了一种轻质减震型动车/地铁车厢底板的制备方法,该方法为:首先从上到下按木质单板A、木质单板B、无纺布、木质单板A、木质单板B、木质单板A、木质单板C、木质单板B、无纺布、木质单板A、木质单板B、木质单板A的顺序组坯,然后热压成型,得到木基复合基材;然后与竹炭板冷压成型,得到竹基复合板材;再在竹基复合板材的最外层木质单板A外均匀喷涂防护涂层,得到轻质减震型动车/地铁车厢底板。本发明通过热压和冷压相结合的方法,将不同的木质单板、无纺布、竹炭板按照一定的组坯顺序进行复合,制得符合技术规范要求的复合板材,该复合板材具有良好的阻尼减震性能和质量轻等优点,并且同时具有阻燃、净醛和耐候等功能。
