Sound insulation and heat preservation board
The sound insulation and heat preservation board comprises a first board body and a second board body bonded with the first board body, a plurality of grooves are formed in the side, close to the second board body, of the first board body, a plurality of noise reduction parts are arranged on the side, close to the first board body, of the second board body, and the noise reduction parts and the grooves are arranged in a one-to-one correspondence mode. The noise reduction part is arranged in the groove; the noise reduction piece comprises a plurality of trapezoidal blocks, and each trapezoidal block is provided with a large end face and a small end face. The noise reduction device is novel in design and easy to operate, by arranging the noise reduction pieces and the like, the noise reduction pieces are multiple trapezoidal blocks, after the first plate and the second plate are connected, the multiple trapezoidal blocks on the second plate can be located in the grooves in the first plate, then when noise penetrates through the grooves, sound waves in the grooves can be reflected by the multiple end faces of the trapezoidal blocks, and the noise reduction effect is improved. And meanwhile, the noise in the grooves is further absorbed by the sound-absorbing cotton, so that the noise penetrating through the second plate is little, and the sound insulation effect is good.
本发明提出了一种隔音保温板，包括：第一板材以及与第一板材粘接的第二板材，其中：第一板材靠近第二板材的一侧设有若干个凹槽，所述第二板材靠近第一板材的一侧设有若干个降噪件，若干个降噪件与若干个凹槽一一对应设置，并且降噪件置于凹槽内；所述降噪件包括多个梯形块，梯形块具有大端面和小端面。本发明设计新颖，操作简单，通过降噪件等的设置，降噪件为多个梯形块，在将第一板材与第二板材进行连接后，第二板材上的多个梯形块会位于第一板材上的凹槽内，进而在噪音穿过凹槽时，凹槽内的声波会被梯形块的多个端面进行反射，同时吸音棉对凹槽内的噪音进行进一步的吸收，使得穿过第二板材的噪音很少，隔音效果好。
