Problems solved by technology

Taking the 50mm thick board as an example, the composite rock wool board can meet the requirements of B-15 fire protection level, and the sound insulation is about 32dB, but it is heavy and the surface density reaches 17kg / m 2 Left and right, and the environmental protection of rock wool construction is not good, it is easy to produce fibers that are irritating to the human body, and it is prone to moisture, and the thermal insulation performance will deteriorate after being wet; although the aluminum honeycomb panel is light, its surface density is only 12kg / m 2 However, the sound insulation is about 2dB lower than that of the composite rock wool board, and the fire protection level can only reach the B-0 level, and the high thermal conductivity of aluminum leads to poor thermal insulation performance of the board

Abstract

The invention discloses a lightweight acoustic insulation and fire resistant ship compartment wallboard and a production method thereof. A connecting structure is arranged on the side of the ship compartment wallboard; the ship compartment wallboard comprises a five-layer structure, namely a panel (1), an interlayer thermal insulation material layer (2), a supporting core material layer (3), another interlayer thermal insulation material layer (2) and another panel (1) in sequence; thermal insulation materials of the interlayer thermal insulation material layers (2) are aerogel. Compared witha composite rockwool panel, the ship compartment wallboard disclosed by the invention has light weight; compared with an aluminum honeycomb panel, the ship compartment wallboard has the advantages that fire-resisting separating performance and acoustic insulation performance are greatly improved.

Description

technical field [0001] The invention belongs to the field of ship cabin wall panels, in particular to a lightweight sound-insulating and fire-resistant ship cabin wall panel and a preparation method thereof. Background technique [0002] Ship cabin wall panels mainly play the role of separating cabin space, sound insulation, heat insulation and fire prevention. At present, the commonly used ship cabin wall panels are mainly composite rock wool panels and aluminum honeycomb panels. Taking the 50mm thick board as an example, the composite rock wool board can meet the requirements of B-15 fire protection level, and the sound insulation is about 32dB, but it is heavy and the surface density reaches 17kg / m 2 Left and right, and the environmental protection of rock wool construction is not good, it is easy to produce fibers that are irritating to the human body, and it is prone to moisture, and the thermal insulation performance will deteriorate after being wet; although the alum...
