Description

Technical Field

[0001] The utility model relates to the technical field of sound-absorbing lining boards, in particular to a sound-absorbing lining board for ships. Background Art

[0002] Sound-absorbing lining is an ideal sound-absorbing decorative material with many advantages and a wide range of applications. There are many types of sound-absorbing panels, including wooden sound-absorbing panels, polyester fiber sound-absorbing panels, and aluminum honeycomb perforated sound-absorbing panels. Wooden sound-absorbing panels are made of fine processing according to acoustic principles and are composed of veneer, core material, and sound-absorbing felt. Polyester fiber sound-absorbing panels are made of polyester fiber as raw material and are made by hot pressing to have sound-absorbing functions. They are often used in engineering noise reduction, especially for high-frequency and high-decibel noise. The structural structure of aluminum honeycomb perforated sound-absorbing panels consists of a perforated panel and a perforated back panel, which are directly bonded to the aluminum honeycomb core with high-quality adhesives to form an aluminum honeycomb sandwich structure. This structure not only improves the sound absorption coefficient, but also enhances the strength of the panel, allowing the size of a single panel to be larger and providing greater design freedom.

[0003] However, after the two sets of sound-absorbing lining panels are fixed to the hull using the keel fixing method, the two sets of sound-absorbing lining panels are usually in contact with each other and are not connected, which will affect the fixing stability of the sound-absorbing lining panels to a certain extent. Therefore, a sound-absorbing lining panel for a ship is invented. Utility Model Content
