Composite underwater sound transmission rubber material and preparation method thereof

Abstract

The invention relates to a composite underwater sound transmission rubber material and a preparation method thereof. A component A is prepared through steps of plasticating natural rubber, then adding into an internal mixer for mixing, adding metallic oxide, inorganic filler, active agent and accelerator for mixing, and discharging sheets by an open mill and testing; a component B is prepared through steps of plasticating chloroprene rubber, then adding into the internal mixer for mixing, then sequentially adding stearic acid, antiager, carbon black, inorganic filler and softener for mixing, adding sulphur for mixing, discharging sheets and cooling down; the composite underwater sound transmission rubber material is prepared through steps of mixing the component A and component B according to proportion of 1:1, packaging into triangle, thinning, discharging sheets, sampling for sulfuration test, and sulfurizing at relatively low temperature. The acoustic impedence of the material and acoustic characteristic impedence of water are well matched, the sound attenuation coefficient of sound wave transmitting in sizing material is low, the material has good hydrolytic resistance and silicone oil resistance; the material can be stored for long time, is safe to operate, has high underwater sound transmission performance, and can be sulfurized at low temperature so that the contradiction between low temperature sulfurization and normal temperature storage is relieved.

AI Technical Summary

Benefits of technology

Inventors have developed an improved type of elastomeric composition called BAKEL® (Bayer Plastics). These compositions consist mainly made up from different types of plastic with specific chemical structures attached through covalently bonded bonds. When combined together they form one part - a mixture of both polymers – these mixtures become more durable over longer periods without losing their effectiveness due to decomposition or deterioration caused by environmental factors such as sunlight exposure during manufacturing processes. Additionally, there has been research on how certain compounds added to improve its properties like flexibility, strength, resistance against tearing under load, etc., making them suitable for use in various applications where high tensile force needs to pass through.

Problems solved by technology

The technical problem addressed by this patented technology relates to developing an effective solution for producing elastomeric materials with excellent sound transmitting properties while also being able safely stored below certain conditions during production or use.
