Problems solved by technology

[0004] However, in the existing FRP-rubber-FRP "sandwich" structure, the rigidity of the sound-permeable rubber material used for the composite sonar dome panel is insufficient. In order to make up for this defect, it is usually necessary to set a With rectangular mesh FRP grille
However, in the actual test process, it was found that the existence of grid-shaped FRP grille caused serious sound wave scattering, which greatly reduced the sound transmission performance of the fairing shell plate
[0005] It can be seen that the rubber materials in the prior art cannot simultaneously meet the requirements of sound permeability and rigidity

Abstract

The invention provides a rubber material and a preparation method thereof, and particularly provides a composite sonar dome shell plate prepared by using the rubber material. The rubber material is prepared from the following components as raw materials in parts by mass: 100 parts of a rubber raw material, 4-6 parts of a vulcanizing active agent, 2-6 parts of an anti-aging agent, 20-70 parts of carbon black, 15-50 parts of a fiber material and a tubular rodlike material, 1-10 parts of a reinforcing and hardening agent and 1.5-10 parts of a vulcanizing system. The rubber material has the average sound transmission coefficient of 95% or above 95% for the sonar frequency of 500-10000Hz, and has the compression modulus being 15MPa or greater than 15MPa; in addition, the rubber material has excellent conventional physical and mechanical properties, so that the rubber material can fully meet using requirements of the sonar dome shell plate.

Description

technical field [0001] The present application provides a rubber material and a preparation method thereof, in particular a composite sonar deflector shell plate prepared by using the rubber material. Background technique [0002] The diversion shell is composed of shell plates and reinforcing components. It has two main functions. The first is the diversion effect, so that the ship has good downstream performance, not only has small sailing damping, but also produces low flow noise; in fact, it is to protect the sonar The underwater array makes it have a quiet acoustic environment, which can fully penetrate the sound waves so as to exert the detection performance of sonar. In the 1990s, the shroud was supported and fixed with a single layer of stainless steel and reinforced with plate ribs. Not only the sound permeability of the metal material of the shroud was too poor, but also the ribs played a role in scattering sound waves. Subsequently, a titanium alloy double-layer ...
