Description

Technical Field

[0001] The invention relates to a noise-reducing floating dressing and a production process thereof, which can be applied to dressings on ships with high noise levels. Background Art

[0002] At present, the cabin deck is generally a steel deck, which has poor anti-vibration performance and poor sound insulation effect. Long-term exposure to noise environment will lead to accelerated fatigue, distraction and distortion of communication information, which will affect the safety of ship navigation for the crew and may cause accidents. Therefore, it is necessary to set up a kind of anti-vibration and sound insulation dressing for some special cabins to meet people's needs. In order to facilitate icebreaking conditions on ships like icebreakers, the noise value of the cabin can be significantly reduced, effectively reducing the harm to people's physical and mental health. Summary of the invention

[0030] In the figure: 1-damping layer, 2-first dressing layer, 3-rock wool layer, 41-top steel plate, 42-damping, 43-lower steel plate, 5-second dressing layer, 6-PVC floor. DETAILED DESCRIPTION

[0031] Example 1

[0032] This embodiment provides a noise reduction floating dressing for ships, which is laid on the deck 7 and has a structure as shown in FIG. Figure 1 As shown, the deck 7 includes a damping layer 1, a first dressing layer 2, a rock wool layer 3, a composite layer, a second dressing layer 5 and a PVC floor 6 arranged on the surface of the deck 7 from bottom to top, wherein:

[0033] The composite layer is composed of a top steel plate 41, a bottom steel plate 43 and a damper 42. The damper 42 is brushed on the surface of the bottom steel plate 43, the top steel plate 41 is laid on the damper 42, and damping seals are used at the edges of the top steel plate 41 and the bottom steel plate 43.

[0034] In this embodiment, the top steel plate 41 and the bottom steel plate 43 in the composite layer are fixed by using rivets or self-tapping screws.

[0035] In this embodiment, the top steel plate 41 and the bottom steel plate 43 are respectively formed by galvanized steel plates arranged in a left-right staggered manner.

[0036] In this embodiment, the rock wool layer 3 is formed by staggered rock wool boards.

[0037] In this embodiment, the thickness of the damping layer 1 is 1-1.5 mm.

[0038] In this embodiment, the first dressing layer 2 and the second dressing layer 5 are both made of self-leveling dressing MS-1200; the thickness of the first dressing layer 2 is 10-15 mm.

[0039] The production process of the above-mentioned noise-reducing floating dressing for ships specifically includes the following steps:

[0040] (1) Grind the welds on the deck surface clean, and then apply primer on the deck surface after grinding. The deck surface should be completely covered with shop primer. The existing primer should be used. The deck surface should be cleaned to ensure that there is no oil, water, particles, dust or other debris to facilitate the adhesion of the primer.

[0041] (2) Damping: According to the thickness of 1-1.5mm, use a scraper to apply Decidamp SLC damping on the deck to form a damping layer. The weight of the damping applied is 1.10kg / M2 / mm per square meter with a thickness of 1mm, and the weight is 1.10kg;

[0042] (3) Wait for the Decidamp SLC damping material to dry. The drying time should be controlled within 6-8 hours. During the process, a hot air blower may be required to provide a suitable temperature. The temperature should be controlled at 15-20°C, and the minimum temperature should not be lower than 5°C.

[0043] (4) After the damping is dry, apply 10-15 mm thick MS-1200 dressing on the damping layer to form the first dressing layer, and cure it at 20°C for 18-24 hours;

[0044] (5) Use a bulk density of 140 kg / m on the first dressing layer. 3 The rock wool is laid closely together to form a 50mm thick rock wool layer. The rock wool should be laid in staggered joints to avoid the joints being in a straight line.

[0045] (6) Lay the lower steel plate on the rock wool layer with a controlled thickness of 3mm, apply a 1mm thick damping layer on the surface of the lower steel plate, and fill the gaps. Lay the top steel plate with a thickness of 2mm directly on the wet damping to form a composite layer, and ensure that each gap of the top steel plate has a little overflow of damping. The edges of the top steel plate and the lower steel plate are sealed with damping, where:

[0046] The top steel plate and the bottom steel plate are formed by staggered arrangement of galvanized steel plates, and the galvanized steel plates in the top steel plate and the bottom steel plate are partially overlapped, and the overlapping part is guaranteed to be at least 30cm in length or width;

[0047] A distance of 5-10mm should be maintained between the galvanized steel plates in the top steel plate and the lower steel plate, between the top steel plate and the lower steel plate and the bulkhead, the hull structure and the through-cabin space. A gap of 5-10mm should be left between the steel enclosure and the lower steel plate, because steel structures can easily transmit noise, and leaving a gap can effectively achieve the noise reduction effect.

[0048] (7) Fix the top steel plate and the lower steel plate with rivets or self-tapping screws, and clean up the excess damping after fixing;

[0049] (8) Apply ARDEX P82 glue on the composite layer by roller coating or brushing, and wait until the surface of ARDEX P82 glue turns transparent and fully dries;

[0050] (9) Apply dressing MS-1200 on the surface of the dried ARDEX P82 glue to form a second dressing layer of 8 mm. The curing time is controlled at 18-24 hours at 20°C.

[0051] (10) A 2 mm thick PVC floor is laid on the surface of the second dressing layer to eventually form a noise-reducing floating dressing.

[0052] In this embodiment, the amount of ARDEX P82 glue used on the top steel plate in the composite layer in step (8) is about 75 g / m2; the temperature of ARDEX P82 glue during construction and drying is 5-35°C.

[0053] The present invention is convenient for use on ships such as icebreakers that have particularly high requirements on noise levels. The floating dressing has been independently developed and uses domestically available materials to adopt a layered design and layered construction, thereby effectively reducing noise.

[0054] In addition to the above embodiments, the present invention may also have other implementation modes. Any technical solution formed by equivalent replacement or equivalent transformation falls within the protection scope required by the present invention.
