Embodiment Construction
[0011] The present invention will be further described in detail below in conjunction with the embodiments, so that those skilled in the art can implement it with reference to the description.
[0012] This case proposes a high-life sound-absorbing panel, which at least includes a combination of polyester fiber, phenolic resin, polyamide resin and pine wood chips. Among them, phenolic resin and polyamide resin are used to improve the structural strength and toughness of polyester fiber, and at the same time help to increase the sound absorption coefficient of the sound-absorbing board; pine wood chips can improve the sound-absorbing performance of the sound-absorbing board, and at the same time help to reduce the weight of the board.
[0013] In the above embodiments, preferably, in parts by weight, 100 parts of polyester fiber, 10-15 parts of phenolic resin, 20-25 parts of polyamide resin, and 8-10 parts of pine wood chips. At this ratio, the performance of the acoustic panel...
