Abstract

A novel underwater sound-absorbing rubber product and a preparation method thereof. It relates to an underwater sound-absorbing rubber product and a preparation method. When the sound frequency is 2-80KHz, the sound absorption coefficient reaches 99%, and the water quality is kept clean even after long-term immersion in water. Each component is 100 parts of synthetic rubber, 1-10 parts of zinc oxide, 1-5 parts of stearic acid, 2640.5-2 parts of anti-aging agent, 30-45 parts of high wear-resistant carbon black N33030, 0-90 parts of light calcium carbonate, Talc powder 0-50 parts, aromatic oil 1-30 parts, naphthenic oil 0-20 parts, paraffin wax 1-10 parts, HY-2056 resin 15-40 parts, Na220-3 parts, DM0-5 parts; mica powder 50 parts -100 parts, 8-15 parts of 100 mesh vermiculite powder, 8-15 parts of 20 mesh vermiculite powder. According to the order of synthetic rubber masticating; adding and mixing of compounding agents; after cooling, add vulcanizing agent and accelerator and mix evenly; when the roller distance is 8mm and ≥65°C, quickly add 20 mesh vermiculite powder, and then vulcanize and form the sheet. Suitable for underwater sound-absorbing rubber products of various shapes and specifications.

Description

Technical field:

[0001] The invention relates to an underwater sound-absorbing rubber product and a preparation method. In particular, a novel underwater sound-absorbing rubber product and a preparation method thereof. Background technique:

[0002] The anechoic pool is a free sound field created in the laboratory. It can simulate the marine environment, identify, calibrate and conduct acoustic navigation tests on underwater acoustic instruments. It is essential for the research and development of underwater acoustic science and the production of underwater acoustic testing instruments. One of the devices. The underwater sound-absorbing rubber product is the laying material of the anechoic pool. Its special underwater sound-absorbing performance makes the anechoic pool similar to an anechoic chamber, and it is the main component of the anechoic pool.

[0003] Since the underwater sound-absorbing rubber products have been soaked in the muffler pool for a long time, it shoul...
