Abstract

The invention relates to a high-temperature underwater sound transmission rubber material and a preparation method thereof. The crystallization of chloroprene rubbers is restrained through selecting the chloroprene rubbers with slow crystallization speed and using butadiene rubbers (BR) with a certain ratio, so that the sound transmission performance and the temperature stability of the rubber material are improved; a certain parts of nanometer clay are added in a formula system to improve the water tightness of the sound transmission material; quick low-temperature and low-pressure vulcanization (100-120 DEG C, 30-40 minutes) of the rubber material is realized through optimizing the rubber material formula and the processing technique design. The underwater sound transmission rubber material with high sound transmission performance, high temperature stability, high water tightness and excellent physical and mechanical properties can be prepared through the method. The material can satisfy the requirements of a coating material of ship underwater sound equipment, and is an excellent underwater sound transmission material.

Description

technical field [0001] The invention relates to a method for preparing a high-performance underwater acoustic sound-permeable rubber material. The prepared sound-permeable material can be used as a coating material for underwater detection devices such as ship underwater acoustic equipment and seabed oil exploration equipment. Background technique [0002] In marine engineering, using sonar detection technology to locate targets is a relatively common method in marine detection, and sonar mainly relies on its key component, the transducer, to transmit and receive acoustic signals, and to ensure the normal operation of the transducer is The basic premise of realizing the detection. Therefore, higher requirements are put forward for the cladding materials of transducers and other underwater acoustic equipment: on the one hand, they must have high sound permeability; on the other hand, they must have good water tightness; . Rubber materials with high sound permeability, good ...
